Safety first – critical health and safety issues you must consider before choosing a water birth pool

Posted on by K.D.Brainin

We are acutely aware of the health and safety risks that are associated with water birth pools.

Back in the mid-80’s when we began to look at designing specialised pools for labour and birth we realised that if safety was not of the highest standard the use of water for labour and birth would not be possible.

Conversations we had with health and safety, infection control and manual handling professionals instilled a passion for safety  that has been there driving force behind every aspect of design, engineering, materials and manufacture.

In 2016, this ongoing dedication led us to publish the Water Birth Safety Initiative (MIDIRS 2016), marking a significant milestone in our quest to elevate safety standards across the globe for water births.

Our profound awareness of the potential health and safety challenges associated with water birth pools compelled us to innovate.

We introduced introduced a range of innovative features that not only mitigate risk but also amplify safety to the highest degree.

Before choosing a water birth pool we invite you to explore the information and guidelines presented in the articles below…

Water safety and infection control risks you should know about before choosing a birth pool

Posted on by K.D.Brainin

Purchasing a water birth pool is a big responsibility.

Not only must financial considerations be taken into account, but more importantly Health and Safety risks.

There are other manufacturers who produce water birth pools that are safe but, many water birth pools are equipped with features that at first might seem safe or even an advantage, but in reality present risks or breach regulations.

These water birth pools (mainly produced in Europe) are over engineered and equipped with a profusion of fittings and features that put mothers and midwives at risk.

(We’re not showing images of other birth pools to illustrate the points below as this could be contentious.)

This whirlpool bath clearly shows a large number of unsafe fittings and systems as applied to water birth pools.
Note the overflow drain, recirculating water system, Swan neck tap, integral shower, rim mounted plumbing and controls

Because they are mounted on the pool, close to the water the potential for pool mounted fixtures and fittings to become contaminated with bacteria and cross infect is greatly increased.

Rim Mounted Taps and Spouts

Rim mounted taps, spouts and showers are one the biggest Health and Safety risks

These fittings present a serious infection control risk as the space between the surface of the pool and the fitting is a suitable breeding ground for bacteria.

Remember – bacteria are microscopic – even though the fitting may appear flush to the surface of the pool there is space for micro-organisms to establish themselves.

The risk that bacteria will propagate in the moisture between the plate and the rim is unacceptable.

There is also a risk that rim mounted taps could be contaminated with water from the pool and flow back into the tap.

There is the potential for back contamination of the tap, with bacterial colonisation into the system in contravention of water fitting regulations

Taps and spouts for water birth pools should be wall mounted 25cm above the pool and fitted with back flow protection as shown in the photo of the Active II Water Birth Pool below:

Surface Mounted Hand Grips (internal and rim mounted)

Surface mounted handgrips are a serious infection control and manual handling risk.

Some water birth pools feature surface mounted hand grips similar to the ones shown above.

The is great potential for bacteria to become established between the fitting and the pool which makes these fittings an unacceptable infection control risk.

The risk of cross-infection is dramatically increased with surface mounted metalwork that is inside the pool as they come into direct contact with the water while the mother is using the pool.

From a manual handling perspective these handgrips are dangerous as they form an obstruction that mothers can hurt themselves on and they interfere with movement around the pool.

Swan Neck Taps

Swan neck taps are often seen mounted on the rims of water birth pools. Though attractive this type of tap presents a significant infection control risk.

Swan neck taps retain larger volumes of water which then stagnates and HFN 30 and HPSC recommends that swan-neck taps should not be used.

This is because they do not empty after use and could be prone to microbial biofouling with microorganisms including Legionella and P. aeruginosa the latter of which was associated with a swan neck tap during the neonatal outbreak in Northern Ireland  (HPSC, 2015).

Re-circulating water systems

Re-circulating or pumped systems with jets such as whirlpools and  jacuzzi present the perfect conditions for the growth of micro-organisms.

Water systems like these present the highest levels of risk as they produce aerosols.

Aerosols are generated when the water surface is broken – for example, by falling water droplets, splashing, or by bubbles breaking at the surface.

Once introduced to these systems, Legionella and Pseudomonas thrive and can become aerosolised and then inhaled.

Integral Plumbing Systems

Plumbing systems like these utilise flexible and non-flexible piping, overflow drains, handheld showers, pumps, hoses, heaters, surface mounted fittings and filters.

 These systems are impossible to clean, disinfect or monitor and therefore present an extremely high Infection Control Risk.

Stagnant water within the system is an ideal breeding ground for bacteria.

UK regulations state that water birth pools fitted with thermostatically controlled  mixer taps plumbed directly into the hospitals water supply.

Hand held showers

Handheld showers present a significant infection control risk.

If the shower head falls in the pool it may be contaminated with bacteria that could breed and be passed on next time the shower is used.

Department of Health regulations clearly stipulate that handheld showers and bath/shower mixers are not installed for use with water birth pools as they present a Fluid Category 5 risk to the mains water supply.

N.B. There are systems available that enable you to detach the hose and shower head from the tap. These are permissible as long as the shower fittings are detached when the pool is in use and only employed afterwards for cleaning.

Integral Plumbing Systems

Plumbing systems like these utilise flexible and non-flexible piping, overflow drains, handheld showers, pumps, hoses, heaters, surface mounted fittings and filters.

These systems are impossible to clean, disinfect or monitor and therefore present an extremely high Infection Control Risk.

Stagnant water within the system is an ideal breeding ground for bacteria.

UK regulations state that water birth pools should be filled with wall mounted, thermostatically controlled mixer taps plumbed directly into the hospitals water supply.

Pumped heating systems

Heating systems for water birth pools are not necessary and present unacceptable infection control risks.

Water is pumped through a heat exchanger and then back into the pool creating the ideal environment for bacteria to breed.

These systems present one of the highest infection control risks and should not be utilised.

Bacteria filters and disinfection systems

Some water birth pools are equipped with these devices in an attempt to mitigate the risk of infection and bacteria infestation that are inherent in built-in plumbing systems.

Bacteria filters and disinfection systems can not be relied upon and will not guarantee adequate hygiene standards.

Overflow drains

Overflow drains harbour bacteria and can serve as a conduit for cross infection.

Regulations are very clear on this point.

Overflow drains should not be fitted to water birth pools as they constitute a constant infection control risk.

Surface mounted metalwork

Metalwork such as grab rails, taps and handles are an obstacle that comes between mother and midwife.

These fittings ALL present a serious infection control risk as the space between the surface of the pool and the fitting are perfect for bacteria.

Remember – bacteria are microscopic – even though the fitting may appear flush to the surface of the pool there is space for bacteria!

Doors

There is no reason for a water birth pool to have a door and many reasons why they should not.

Doors are mistakenly used for two reasons:

  1. To facilitate emergency evacuations
  2. To help mothers get in and out of the pool

Doors present an extremely high risk of infection and should be banned from use in water birth pools for this reason alone.

The door seal (typically foam or rubberised material) is the perfect breeding ground for bacteria.

From manual handling perspective doors are not practical or fit for purpose.

They actually complicate emergency evacuations and put mothers and midwives at risk.

Winner – Building Better Healthcare Awards

Posted on by K.D.Brainin

At the ‘Building Better Healthcare’ awards ceremony the Active Birth Pool was highly commended in the award for best internal building product.

In their comments the judges praised the quality of  our design and manufacturing process and went on to say that they found the Active Birth Pool very appealing.

active-birth-pool-award
All aspects of design, engineering and manufacture were focused on develop a water birth pool of unparalleled beauty, quality, functionality and durability that is backed by an extraordinary life-time year guarantee.

Foremost consideration was given to how mothers and midwives relate to and interact with the pool employing ergonomic principles to design for the interaction and dynamic at play.

Mothers have the space to move freely and comfortably and are supported in the postures natural to a physiological labour and birth.

The “signature” extra-wide rims with broad “bull-nosed” shaped edges flowing into the skirting panel and down to the floor are an important feature of the Active Birth Pool that sets it apart.

The wide flat rim allows mothers to lean forward, resting on their forearms in comfort – one of the most natural and effective positions during labour.

It provides secure, safe, stable support for women to enter and leave the pool and for midwives and partners to lean or rest on while attending the mother.

The handrails, which are set into the profile of the rim, provide perfect support for the mother in upright positions.

The critical issue of emergency evacuation has been resolved by incorporating features into the pool to give midwives several options for evacuating the mother that are in compliance with Health & Safety and Manual Handling regulations.

The Labour Support and Safety Seats are distinguishing features of the Active Birth Pool

1) This physiologically designed labour support seat has proven to help the mother’s pelvis and birth canal open in preparation for a natural, physiological birth.

2) The distinctive rim level safety seat provides a wide comfortable platform for the mother to lean on, a safe means for emergency evacuation and is ideal for midwives to monitor the mother without her having to stand up or leave the pool.

The unique seamless one-piece construction incorporates a deeply sculpted concave skirting panel to allow midwives to work in comfort with their legs well under the pool.

The new Active Birth Pool is fabricated in Ficore® composite, a proprietary material that was specially developed for baths and designed to negate the risk of problems associated with other materials.

Ficore is 50% harder than acrylic and fibreglass (which other birth pools are made from) and highly resistant to chemicals.

Despite the rigidity and hardness of the surface it is extremely smooth, tactile and warm to the touch.

Its high insulation factor enables the Active Birth Pool to maintain its temperature up to six times longer than standard acrylic or fibreglass birth pools.

To help mothers control, define and personalise the delivery room, the Active Birth Pool is equipped with multi-colour chromotherapy LED lighting and integral bluetooth sound.

Our ingenious Integral Bluetooth Sound System allows the mother to wirelessly connect her phone and listen to the music of her choice.

Two integral speakers turn the birth pool into a highly refined audio loudspeaker.

When you examine the new Active Birth Pool you’ll immediately notice the superior finish and signature design elements.

Look a little closer and the quality of the components such as the drainage system, the support structure that underpins the pool, the fittings on the access panel, the lighting system, handrails and metal work becomes apparent.

If you are looking for a water birth pool to install in a maternity unit the incomparable new Active Birth Pool should be your first choice.

Handmade and custom built to order by a team who together have over 95 years experience in the design and production of high-end baths the new Active Birth Pool will provide decades of service and be an invaluable aid to mothers who want to have a natural birth.

The Active Birth Pool conforms to regulations issued by the Department of Health and the guidelines set forth in the Water Birth Safety Initiative.

Guidelines: Getting in and out of the pool

Posted on by K.D.Brainin

The simple act of getting into the pool is one of the most misunderstood aspects relating to the use water birth pools.

The truth is that multi-step units are dangerous and in the case of Active Birth Pools unnecessary as the video below clearly demonstrates.

Health and Safety and Manual Handling experts strongly advise against the use of multi-step units as they present unacceptable safety risks.

They say that, “mothers in strong labour should not climb up and over the rim of the pool and down onto a submerged plinth because it is not safe or practical”.

In addition these bulky step unit take up too much space, obstruct movement around the pool and are a trip hazard.

With the help of Manual Handling  and Ergonomic Design  experts we designed a simple, safe way for mothers to get into our pools.

The distinctive extra-wide, bull-nosed shaped rim is relatively low making it perfect for mothers to sit on and gently swivel into the water.

There is no climbing – mothers are grounded at all times and safeguarded from risk.

All women no matter what their shape or size will find it exceptionally easy to get into our pools.

Mothers don’t even think about it – they move instinctively and naturally lower themselves into the water.

And midwives will be safeguarded from the risk associated with physically supporting mothers as they climbs up the steps .

To put this in perspective:

The average height of our pools is 75cm – about the same height as a desk or dining table.

Our 15cm high single step makes the height of the pool  60cm – the same height as an ordinary bathtub.

You don’t need a big step unit to get into your bath at home, do you?

Guidelines: Dealing with emergency evacuation

Posted on by K.D.Brainin

Active Birth Pools give midwives safe, practical options for dealing with emergencies.

The evacuation a collapsed woman is potentially hazardous and poses risk of injury to mother and midwife.

If the need for an emergency evacuation arises the midwife should:

  1. summon help
  2. stabilise the mother
  3. turn the taps on to raise the water to rim level.

The buoyancy of the water reduces the relative weight of the mother by approximately 33% making it easier to move her and effect safe evacuation.

Midwives should float/move the mother onto a seat or support and hold her safely until help arrives.

Basics:

  1. The mother should be screened to ensure that she meets the inclusion criteria prior to entering the birth pool.
  2. Continuous risk assessment is essential to reduce the incidence of emergencies in the pool.
  3. At the first sign of a contraindication the mother should be asked to get out of the water and assisted from the pool for monitoring and care.
  4. If the mother is unable to leave the pool under her own power or has collapsed an emergency evacuation will need to be conducted.
  5. A trolley should be available
  6. for the mother to be moved onto.
  7. Care must be taken that proper lifting techniques are employed to avert strain & injury.

Example 1: Emergency evacuation utilising the labour support seat

Active Birth Pools are portable hoist compatible

Manual Handling advisors may insist that women are evacuated from the birth pool with a hoist and that this facility is provided for.

Active Birth Pools are designed to accommodate a portable hoist should the need arise.

  • Venus II Water Birth Pool: 2050 x 1420 x 890mm 205kg
  • Princess Birth Pool: 1670 x 1170 x 890mm 145 kg

The birth pool should be unpacked from the timber crate but left in its protective packaging for moving from the delivery point to the room where it will be installed.

The pool should be gently turned on its side onto a padded movers dolly or two to  enable it to be easily moved along corridors and through doorways. It’s best to handle the pool by the rim as this is the strongest point.

Installation

Prior to moving the birth pool into position against the wall the plumbing (taps and drainage) and electrical services should be in place ready for final connection to the pool.

Taps

Fix a 3/4″ thermostatically controlled mixer tap with a 150mm spout on an IPS panel 25 cm above the rim of the pool (rim height 75cm).

We suggest that you consider the Rada Sense Bath T3 (or similar) as it is a digital tap that not only enables you to programme the http://activebirthpools.com/wp-content/uploads/2015/10/Rada-1.pdfwater temperature but also the fill time.

A filling time of 20 – 25 minutes is acceptable.

Drainage

The pool is supplied with a bespoke brass 40mm pop up waste that is operated by a control that is fixed to the rim.

The waste is connected to a P Trap  and a McAlpine T25 adaptor

Height from the floor to the centre of the T25 adaptor is 11cm

From the T25 adaptor you can utilise of a wide variety of commonly available parts to connect to the pipework of the buildings drainage system.

When electrical and plumbing services are in place and ready for the final connection to the pool’s systems the pool should be moved into position and fixed to the floor.

Final connection of services can be carried out through the access panel when the pool is secured in place.

Fixing the birth pool to the floor

All feet MUST be in solid contact with the floor.

If the floor is not level or smooth be sure to adjust the feet or level the floor so that all of the feet are in firm contact with the floor and there is no rocking or movement.

The bottom flange of the outer panel should be in contact with the floor but is not the primary support structure of the pool and must not bear the full weight of the filled birth pool.

The water birth pool is supplied with 3 x 100 mm x 30 mm fixing brackets.

You’ll find the brackets taped to the pool just inside the access panel that can be opened with a 10mm Allen Key.

It is essential these brackets are securely fixed to the floor with suitable hardware to immobilise the pool and prevent it from moving when empty.

Failure to secure the pool to the floor with the fixing brackets will endanger the end user and VOID the guarantee.

Locating and fixing the brackets

Step 1: All Models:

Mark the central position of the water birth pool on the wall that it is being fitted on.

Step 2:  Active Birth Pool – front fixing bracket

Measure 1220 mm from the centre point on the wall and mark this as the point to locate the bracket so that the long flat piece is projecting away from the wall and the raised short section faces forward into the room.

Fix the bracket to the floor using suitable hardware.

Front bracket right centre – Back bracket lower left

Step 2:  Active II Water Birth Pool – front fixing bracket

Measure 1330 mm from the centre point on the wall and mark this as the point to locate the bracket so that the long flat piece is projecting away from the wall and the raised short section faces forward into the room.

Fix the bracket to the floor using suitable hardware.

Front bracket right centre – Back bracket lower left and right

Step 2: Venus Birth Pool – front fixing bracket

Measure 1070 mm from the centre point on the wall and mark this as the point to locate the bracket so that the long flat piece is projecting away from the wall and raised short section faces forward into the room.

Fix the bracket to the floor using suitable hardware.

Front bracket right centre – Back bracket lower left

Step 2: Venus II Water Birth Pool

– front fixing bracket

Measure 1330 mm from the centre point on the wall and mark this as the point to locate the bracket so that the long flat piece is projecting away from the wall and the raised short section faces forward into the room.

Fix the bracket to the floor using suitable hardware.

Front bracket right centre – Back bracket lower left and rightt

Step 2: Princess Birth Pool Pool – front fixing bracket

Measure 1020 mm from the centre point on the wall and mark this as the point to locate the bracket so that the long flat piece is projecting away from the wall and raised short section faces forward into the room.

Fix the bracket to the floor using suitable hardware.

Front bracket right centre – Back bracket upper left

Step 3: All Models

Place the birth pool at least 60 mm away from the rear wall before moving it onto the bracket and flush against the wall.

Push the birth pool towards the wall so that the flange of the pool slides under the bracket.

This secures the front of the pool to the floor.

Step 4: All Models – back fixing bracket

The 2nd fixing bracket should be fixed in position on the bottom flange of the pool below the access panel as indicated in the images above.

You will see that a hole has been drilled in the flange. Line the bracket up with this hole. You can fix the pool to the floor with a raw plug and suitable hardware to guarantee that it is secure.

The long flat piece should be fixed to the floor with suitable hardware so that the short section is holding the flange securely to the floor.

Step 5: All Models

Seal the water birth pool to the floor and wall using a suitable sealant to prevent ingress of water and dirt.

Multi-Colour LED Lighting

Installation

Connect the light to a circuit breaker, then to the power supply.

The system should be protected by a 6 AMP RCD with 30 -32 MA Sensitivity.

The LED is transformed down to 12 volts and has a power rating of 2.5 watts.

A separate means of Isolation should be provided for future maintenance.

Operating voltage 220/230 volts – 50/60 hertz

Operating instructions

The system is operated by the control pad on the rim of the pool.

To activate the system press the button once.

The white light will come on.

To choose another colour continue to press the button and the system will cycle through the range of colours – light blue, blue, purple, magenta, red, pink, orange, yellow, apple green and green.

To turn the system off press and hold the button down for 2 seconds.

The light should be switched off when the pool is not in use.

Bluetooth Sound System

Connect the factory fitted bluetooth sound system to a circuit breaker and then to the power supply.

The system is always on standby waiting for users to pair and connect.

It’s operated directly from the users mobile phone or bluetooth enabled device and has no controls of its own.

N.B. If there is more than one birth pool with bluetooth sound being installed in the same unit you will need to fit a remote switch to enable the users to turn the system on and off.

This is to prevent people accidentally activating the system instead of the one in their room.

  • Transformed Voltage 12 Volt DC / 3 amp.
  • Waterproof Rating IP67.

Cleaning and Care:

Safety comes 1st!

Active Birth Pools  are Rated No.1 for water safety and infection control standards.

This is because the material we use (Ficore) is 5 x harder than other materials and is immune to the effects of disinfection with 10,000ppm hypo-chlorite.

Seamless one-piece construction and the absence of surface mounted metal work deny micro-organisms the environment they need to propagate.

Active Birth Pools Cleaning and Disinfection Guidelines

This is a two-step procedure – first cleaning of the pool and surround, then disinfection of the pool and surround.

  1. Prior to emptying the pool remove debris and larger particles from the water with a sieve to prevent it from blocking or obstructing the outlet.
  1. Use the standard infection control precautions (plastic apron, disposable gloves and eye protection) when cleaning the pool. Ensure the area is well ventilated.
  1. Cleaning – use a non-abrasive detergeant with non-abrasive sponge or cloth to thoroughly clean the pool. Ensure the tap is cleaned first, so as not to transfer micro-organisms from the “dirty” pool area to the cleaner tap region. Rinse well with warm water.
  1. Disinfecting – use chlorclean or similar hypochlorite disinfectant following the directions on the packet for mixing the solution to the correct concentration for disinfecting the birth pool and surround.  Do not use bleach as it is highly corrosive and could cause damage to the fittings.
  1. Apply the solution to the tap and spout prior to disinfecting the pool.
  1. There are 3 methods for disinfecting the pool that are commonly used in hospitals:

1) Fill the pool with cold water and add the requisite amount of disinfectant – leave for ten minutes.

The advantage of this method is that it is 100% effective but wasteful of water, time consuming and uses a large amount of disinfectant

2) Make up 2-3 litres of solution and pour it around the inside of the rim. Then use a new disposable mop or cloth to spread the disinfectant over the surface of the pool. Leave for ten minutes.

The advantage of this method is that it is economic in terms of time and cost but relies upon the person carrying out the task to ensure that 100% of the pools surface is disinfected.

3) Fill a spray bottle with disinfectant and thoroughly spray the surface of the pool and surround. Then use a new disposable mop or cloth to spread the disinfectant over the surface of the pool. Leave for ten minutes.

The advantage of this method is that it is economic in terms of time and cost but relies upon the person carrying out the task to ensure that 100% of the pools surface is disinfected

  1. Open the drain outlet and empty the pool of the disinfectant.
  1. Using cold water, rinse the tap then the pool to remove all traces of the disinfectant, to prevent any residue being left on the pool surface.
  1. Dry the entire surface of the pool using a new cloth or disposable mop head.
  1. Keep the drain outlet closed when not in use.

If you are duty flushing the taps with hot water/steam add a few inches of cold water to the pool first.

Damage resulting from higher water temperatures, steam cleaning or use of products not approved by Active Birth Pools will not be covered by our guarantee.

If you are duty flushing the taps with hot water/steam add 10cm of cold water to the pool first.

Important Update

Hospitals worldwide are starting to use Copper / Silver orca disinfection systems in an effort to combat bacterial issues and improve water safety.

We have discovered that there is great potential for staining with the Copper / Silver orca disinfection system

Copper-silver ionization systems introduce trace amounts of copper into the pool water.

In some cases, exposure to elevated copper levels can lead to staining of the sanitary ware and other surfaces, such as walls, floors, or fixtures.

Please note that staining caused by these systems is NOT covered by our guarantee.

If your hospital is using one of these water treatment systems we suggest that you contact the department responsible for water safety as regular monitoring and appropriate copper levels are essential to mitigate the risk of staining.

Protocols from hospitals using Active Birth Pools.

 

How to restore your old birth pool to pristine condition

We’ve been supplying water birth pools to hospitals since 1989.

Many of the pools we supplied in the 90’s are still in active service!

We occasionally receive reports that the pools are not looking as clean and bright as they originally were.

Not to worry.

There is a product called tide mark cleaner that was developed for spas and swimming pools.

You can either use it to remove stains or brighten up the appearance of the pool when necessary.

It will restore your pool to pristine condition.

Water Birth Safety Initiative

Posted on by K.D.Brainin

Hospitals in the United Kingdom began allowing women to use specially designed pools of water for labour and birth during the 1980’s.

The wide-spread popularity and acceptance of water birth pools as a standard part of the maternity care package necessitated the development of guidelines & regulations to define standards and ensure they’re met.

The United Kingdom Department of Health has published a panoply of water safety directives that apply to water birth pools.

Policies and recommendations set forth in the Water Birth Safety Initiative are based upon these publications.

The Water Birth Safety Initiative (WBSI) calls for development of international standards modelled on the UK’s so that women the world over can benefit from the use of water for labour and birth safeguarded from risk.

The WBSI calls for the implementation of stricter protocols and sets forth recommendations for equipment standards.

The guidelines set forth in the WBSI are intended to serve as a framework of standards for birth pool suppliers, hospitals and midwives to work with to establish  safe codes of practice.

Guidelines for Water Birth Pools Installed in Hospital

Water is more prone to bacteria growth after it leaves the public water distribution system and enters a building’s plumbing.

There it finds warmer temperatures, stagnation, and smaller pipes, valves and fittings.

Biofilm that forms on valves and fittings and pipe walls not only feeds bacteria but also protects them from the hot water and chlorine that typically would kill free-floating organisms.

Large systems with complex piping networks — like those found in hospitals, hotels and large apartment buildings — are especially prone to bacteria growth.15

Water Birth Pools that are installed in hospitals have the benefit of being maintained by staff to ensure that protocols are established, met and maintained.

Consideration and due diligence with regard to the prospective purchase of water birth pools and the assessment of pools already in use needs to be taken to ensure that the associated plumbing and electrical systems meet relevant safety standards.

The United Kingdom’s Department of Health and National Health Service has an exemplary safety record achieved by establishing rigorous sets of guidelines and regulations for the design, installation, use and maintenance (cleaning/disinfection) of water birth pools.

In the UK water birth pools are classed as a Category Fluid 5 water risk which represents a serious health hazard due to the concentration of pathogenic organisms, radioactive or very toxic substances, e.g. containing faecal material or other human waste; butchery or other animal waste or pathogens.

Water Birth Pools must be installed in compliance with water regulations as set forth in The Water Supply (Water Fittings) Regulations 1999.11

The 7 sins of water safety

To ensure high standards are met it is strongly advised that you do not use a water birth pool that has any of these features:

  1. Overflow drains
  2. Internal water inlets
  3. Hand-held showers
  4. Systems with flexible hoses or extended pipes
  5. Integral or secondary plumbing systems
  6. Any type of recirculating or pumped water systems such as whirlpool, jacuzzi, spa, bubbling, filtering etc
  7. Heating systems

1) Overflow drains

Overflow drains harbour bacteria and can serve as a conduit for cross infection.

Regulations are very clear on this point – overflow drains should not be installed on water birth pools as they constitute a constant infection control risk much more significant than the possible risk of damage due to water overflowing.11,12

Some digital taps on the market can be set for filling time thus obviating the risk of the pool overflowing.

2) Internal water inlets

Internal water inlets act in place of taps to fill the pool.

They are installed on the inside of the pool just above the water line and connected with pipework to a thermostatic valve.

If the water level rises there is a high risk of back flow enabling bacteria to enter the system creating a risk of cross infection.7

3) Handheld showers

Handheld showers present a significant infection control risk due to the fact that they can fall in the pool and be contaminated with bacteria that could breed and be passed on next time the shower is used.

Department of Health regulations clearly stipulate that handheld showers and bath/shower mixers are not installed for use with water birth pools. 13

Handheld showers present a Fluid Category 5 risk to the mains water supply.

It must not be possible to submerge the showerhead in the water due to risk of cross infection.

In order to comply with category 5 water regulations covering back siphonage, a class AUK3 air gap would be required, which generally prevents the use of handsets, unless there is a separate break tank installed in the hospital plumbing system.

4) Systems with flexible hoses or extended pipes

Systems that employ flexible piping, have branch pipes or hold stagnant water present a potential hazard and must not be used with water birth pools.

It is impossible to clean, disinfect or monitor these systems.

They have been proven to be a source of Legionella and Pseudomonas. 14

Weekly flushing recommendations recommended by the department of health cannot be executed with such systems, and the effectiveness of this cannot be monitored due to the inacessibility of the closed system.

5) Integral or secondary plumbing systems

Integral, secondary or proprietary plumbing systems are fitted to some water birth pools.

As these systems can employ flexible and non-flexible piping, overflow drains, handheld showers and are often pumped or recirculating they present a significant infection control risk and should be banned from use.

Regulations stipulate that water birth pools are filled from thermostatically controlled wall mounted mixer taps plumbed directly into the hospitals water supply with the minimum of pipework.

Not only do secondary or integral plumbing systems present unacceptable risks, they are impossible to clean, disinfect or monitor and therefore present an extremely high and unacceptable infection control risk.

They must not be present on pools used for labour and birth. 10

6) Recirculating or pumped water systems

Recirculating or pumped water systems such as whirlpool, jacuzzi, spa, bubbling, filtering etc. have the perfect environmental conditions to be a potential source for the growth of microorganisms, including legionella bacteria and must not be installed on water birth pools.

Water systems that are able produce aerosols represent the highest levels of risk.

Aerosols can be generated very easily when the water surface is broken -for example, by falling water droplets, splashing, or by bubbles breaking at the surface.

Once introduced to artificial water systems, Legionella can thrive in warm water (30 – 35 °C) and has been shown to be present on flexible seals and metal surfaces within plumbing systems used in domestic potable water supplies.

Inadequately maintained spa pools (birth pools with pumped or recirculating systems) provide ideal conditions to support the growth of legionellae and other microorganisms, which may then become aerosolised and subsequently inhaled.15


7) Heating systems

Heating systems for water birth pools are not necessary and present unacceptable infection control risks.7

There are two types of heating systems in use:

1. Recirculating system with a heat exchanger

Water is pumped out of the pool and through a heat exchanger and then flows back into the pool.

These systems present one of the highest infection control risks and should not be installed on a water birth pool under any circumstances. (covered by points 4, 5 and 6 above).

2. Electric heating systems

Similar to under floor heating found in homes do not present an infection control risk.

But, they do present an unacceptable health and safety risk and should therefore not be installed in water birth pools.

These systems consist of a network of cables embedded in the fabric of the birth pool that are attached to the power supply through a thermostat.

The heat is transmitted from the cables through the floor of the pool and then transferred to the water.

The inherent problem with these systems is that the water is relied on to take the heat away from the material.

If a woman remains motionless the heat becomes concentrated and a “hotspot” develops which can result in the woman being burned.

Recommendations

Plumbing for filling and emptying water birth pools should be simple, straight forward and kept to the minimum.

A set of taps (see below) mounted on the wall 15cm above the rim and a drainage system similar to that of a normal bath is all that is required.

Rim mounted taps present two areas of risk:

1. Women may hit their head on taps that are mounted on the rim of the pool causing injury.

In the throes of labour a woman is not as cognisant of her surroundings as she normally is.

She needs to be protected from the potential harm that could result from hitting her head or other part of her body on the spout.

2. Risk to the taps and pool caused by the labouring woman grabbing onto the spout for support could easily cause damage to the fitting or fabric of the pool.

Filling the birth pool

Water Birth Pools should be filled directly from the hospitals main water supply through a ¾ Thermostatic Mixing Valve (TMV).

To comply with UK National Health Service regulations the valve must have TMV3 approval for use in Healthcare and Commercial situations and certify that it conforms to the performance requirements of the Department of Health.16

To kill legionella and other bacteria, water in hospitals systems is heated to 60 – 80 °C.

Water temperature entering the birth pool should be limited by the TMV to 44 °C to prevent scalding.

The added benefit of using a TMV connected directly to the hospitals main water supply is that it can be set to automatically flush itself of stagnant water twice a day and be thermally disinfected periodically.

dsc_2965

The use of a TMV ensures a safe water supply.

Digital thermostatic mixing valves with enhanced thermal performance that incorporate these features are ideal:

1) Programmable control to accurately mix and maintain the temperature of the water flowing into the birth pool and limit the temperature of the water to 44 °C to prevent scalding.17

2) Programmable fill duration to fill the pool to the desired depth and then turn off.

This is important as water birth pools are not allowed to have overflow drains installed and this feature will prevent the pool from overflowing when unattended.

3) Programmable duty flushing to ensure that water does not stagnate within the tap and associated pipe work, effectively controlling the multiplication of legionella & other bacteria in infrequently used outlets.

Flushing duration is in line with HSE L8 recommendations.18

4) Programmable high-temperature thermal disinfection to destroy the proteins in viruses and bacteria and render them as dead or inert.

Thermal disinfection works by achieving a moist heat which is set at a specific temperature for a set amount of time.

Viruses and bacteria are very sensitive to heat and they will die if exposed to higher temperatures. 19

Emptying the Pool

Water from a birth pool needs to be treated as Fluid category 5 waste representing a serious health hazard due to the concentration of pathogenic organisms derived from fecal material or other human waste and emptied directly into the hospital’s waste water system.20

The pipework needs to have a trap or U bend fit as close to the waste/drain as possible.

The drainage fitting or waste should seal neatly into the drain.

The drainage fitting should be cleaned and flushed through with disinfectant and then dried as part of the cleaning protocol.

The waste should be kept closed when the pool is not in use.

There should be NO flexible pipe used in the drainage pipework.21

The waste should be remotely operated (i.e. pop up waste with rim mounted control) and of the best quality, preferably high-grade brass, to resist the corrosive action of chlorides and other disinfectants.

The Water Column takes water safety to a new level

Posted on by K.D.Brainin

Freestanding water birth pools are becoming increasingly popular.

These installations typically present significant water safety and hygiene risks as rim mounted plumbing and fixtures provides the perfect breeding ground for micro-organisms to thrive.

For wall mounted installations the thermostatic taps, spout, handheld shower and grab rail are fixed to an IPS Panel in accordance with health department regulations.

For freestanding birthing pools a solution needed to be found.

To solve this problem we developed the Water Column – a bespoke design concept that separates the plumbing from the pool to optimise hygiene and water safety and provide crucial support for mothers and midwives.

It’s highly utilitarian, sleek ergonomic design complements the look and usability of our pools to create the ideal facility for water birth.

The wide rim, step unit and grab rail make it safe for mothers to get in and out of the pools.

The column is the perfect height for midwives to rest and lean on while attending the births.

Mothers have a choice of hand holds for support in upright and standing positions.

Adding colour to the column and step adds another dimension to the ambiance of the room.

The Water Column is available in the full range of British Standard or RAL colours.

The demountable handheld shower is essential for cleaning the pool after the birth.

It should be removed while the pool is being used to maintain optimum hygiene standards  and to not contravene relevant water safety regulations.

The Water Column has a large access panel at the back that opens up to give plumbers plenty of room to install the thermostatic mixing valve, pipework and associated fittings.

We supply the Water Column only, and not the plumbing or fittings pictured in the images above.

Shown is the Rada T3 Bath/Shower Tap with Rada Spout and Grohe Demountable Handheld shower.

How to restore your old birth pool to pristine condition

Posted on by K.D.Brainin

We’ve been supplying water birth pools to hospitals since 1989.

Many of the pools we supplied in the 90’s are still in active service!

Below Venus Pool at the Royal Berkshire Hospital 1992 – still in use today

hospital birth pools client list

We occasionally receive reports that the pools are not looking as clean and bright as they originally were.

Not to worry.

There is a product called tide mark cleaner that was developed for spas and swimming pools.

You can either use it to remove stains or brighten up the appearance of the pool when necessary.

It will restore your pool to pristine condition.

When it comes to the creation and care of water birth facilities nothing is more important.

Micro-organisms breed freely in warm moist environments and must be prevented from propagating.

Below a list of guidelines to help you create a safe water birth facility.

 

Birthing Pool Rules: Journal of Water Safety Forum Spring 2021

Posted on by K.D.Brainin

Water births are largely considered safe — but are there potential microbiological risks? And what are the best recommendations to eliminate any possible dangers?

Dr Jimmy Walker clarifies some of the advice outlined in an upcoming ‘back to basics’ book* aimed at training and education on the potential microbiological risks from water in healthcare facilities.

Water births have long been considered a safe way of giving birth for women who are not expected to have complex deliveries, with the literature backing up this record to show that rates of neonatal infections are no greater in water births than conventional bed births.1,2,3,4

However, this doesn’t mean there are no risks at all. Rare instances of adverse events have occurred, including microbial neonatal infections caused by a range of organisms that have included Legionella, the cause of Legionnaires’ disease, and Pseudomonas aeruginosa — although these have largely been related to home births.

There are several routes for potential contamination of water during a water birth:

Water supply

If either of the above organisms were found in a pool, this would indicate either contamination in the water system or at the tap outlet. If only a tap outlet were colonised, the contamination may be diluted to negligible levels in the pool once that tap is run. However, running a tap when there is biofilm build-up, either in the last two metres or further back in the system, would continue to release microorganisms leading to microbial concentrations in the pool water that could lead to infections.

This is a highly unlikely scenario that would only occur if water maintenance has been neglected enough to allow conditions for microbial growth to develop: for example where pipes have not been lagged properly causing the hot water to become cooler and the cold pipe to become warmer, creating ideal temperatures to enable growth of Legionella bacteria, for example.

Bodily fluids, birthing ‘debris’ and maternal contamination

As part of the birth process, water in birthing pools will inevitably be contaminated by bodily fluids and ‘debris’, such as placenta, some of which will be caught in strainers. Pool water can also be contaminated by faecal matter and any P. aeruginosa the mother may be carrying (P. aeruginosa can occur naturally on the skin of healthy individuals), although newborns are unlikely to be at risk from maternal ‘flora’.

A clear protocol is essential for drainage of the pool, cleaning and also disinfection to remove this contamination. All accessories must also be cleaned and thoroughly disinfected — or be single use.

If contamination is not properly dealt with, then any remaining residues will encourage microbial growth that could lead to potentially dangerous contamination of the next user’s water.

 Drains

The role of drains as a source of healthcare associated infections (HAIs) and potential reservoirs of antibiotic resistant organisms is now being regularly documented, with carbapenem-resistant Enterobacteriaceae (CREs) a particular concern.

Single use plugs and strainers are now most commonly used, with a large access valve for nurses and midwives to retain water in the bath. However, because birthing pools are usually located at floor level, the gradient of the drainage pipework may not be sufficient to remove the material caught in the drain. Although such an event has not yet been reported, this creates the potential for biofilmbuild-up over time, to a level that may be difficult for disinfectants to penetrate and possible contamination of the pool as soon as it is filled.

Birthing pool design

Birthing pools could be improved to prevent this backflow scenario from the drain, with designs that ensure efficient drainage of contaminating material and valves and drains that are easy to disinfect.

There are also examples of birthing pools where the pool is filled via a wall tap that enters the pool at a level where the water could flow back into the tap. This again has the potential for back contamination of the tap, with bacterial colonisation reaching even further back into the system in contravention of the water fitting directive.

Birthing pools should be designed with taps that are well above the pool’s edge and which are fitted with suitable backflow protection.

Some birthing pools also have an associated showerhead for cleaning the pool after use. However, this is also inadvisable as the flexible hose and shower head may become contaminated when they are suspended in the water. This could not only lead to backflow and contamination of the supply, but also, the contaminated hose and shower head could introduce harmful bacteria to the pool if they are not cleaned and disinfected appropriately or replaced between uses.

In addition, because water births are not always considered appropriate, there may be a prolonged period when the pool is not used. Where this is the case, a flushing regime is essential to minimise water stagnation, biofilm build-up and microbial proliferation in the water supply.

Resolving issues

Maternity units are well aware of the risks and must carry out their own risk assessments, but it is important that they are assisted in this by appropriate members of the hospitals’ water safety groups (WSGs – see p 10-12), who can provide additional specialist knowledge e.g. from microbiologists and the estates team.

Health and Safety Advisory: WARNING Swan Neck Taps Present a Significant Infection Control Risk

Posted on by K.D.Brainin

Swan neck taps are often seen mounted on the rims of water birth pools.

However, swan neck taps retain larger volumes of water which then stagnates and HFN 30 and HPSC recommends that swan-neck taps should not be used as they do not empty after use and could be prone to microbial biofouling with microorganisms including Legionella and P. aeruginosa the latter of which was associated with a swan neck tap during the neonatal outbreak in Northern Ireland  (HPSC, 2015).

Taps for water birth pools should be wall mounted, NOT rim mounted and conform to WRAS regulations.

The use of water for labour and birth – Colchester University Hospital

Posted on by K.D.Brainin

Feeling relaxed, secure and in control and being able to move about freely can make
it more likely for you to have a quicker and more natural birth.

For some women using a birthing pool can offer all of these benefits.

Today more and more women are considering using water for pain relief in labour.

A midwife can support you in using a birthing pool at home or in our midwife-led units
at Colchester General Hospital and Clacton and Harwich hospitals in the community.

Using a birthing pool is likely to increase the chances of a normal vaginal delivery
and therefore we would like to offer this option to as many women as possible.

We have compiled this leaflet to give you and your partner relevant information about
labouring and giving birth in water.

Please talk to your midwife during the antenatal period who will be able to answer any questions you may have.

The use of water in labour and birth – NZ College of Midwives

Posted on by K.D.Brainin

The New Zealand College of Midwives (Inc) supports immersion of women in warm water during labour as a method of pain management.

There is no evidence that remaining in water for the birth of the baby leads to adverse outcomes for the mother or baby where the labour has been within normal parameters.

Definition:

Water birth means where a baby is born fully submerged into water.

Rationale:

• Evidence supports immersion in warm water as an effective form of pain relief that reduces the use of narcotics.

• There is no evidence to suggest that immersion in water during labour or birth in water leads to any detrimental effects for either the mother or her baby.

• Evidence that immersion in water during labour reduces the length of active labour is inconclusive.

• Evidence that birth in water reduces perineal trauma or blood loss is inconclusive.

Guidelines:

Midwives offering water immersion for labour and for birth are responsible for ensuring the information given to women is accurate and up to date.

The following guidelines are recommended:

• There are no adverse factors noted in foetal or maternal wellbeing during labour.

• Baseline assessments of both maternal and baby wellbeing should be done prior to entering the bath/pool and assessments continued throughout the time in water as for any normal labour.

• Vaginal examinations can be performed with the woman in water.

• Pethidine should not be given to women labouring in water.

• The water temperature should be kept as cool as the woman finds comfortable during the first stage of labour (around 35oC) and increased to no more than 37oC for the baby’s birth.

• If maternal temperature rises more than 1oC above the baseline temperature then the water should be cooled or the woman encouraged to leave the bath/pool. Women need to be aware of this in advance.

• Water temperature should be recorded as the woman enters the bath/pool and regularly during the time she remains in the pool.

• Careful documentation should be kept of maternal and water temperatures, FHR and the approximate surface area of the woman’s body submerged.

• The cord should not be clamped and cut until after the birth of the baby’s body.

• The baby should be brought to the surface immediately, with the head facing down to assist the drainage of water from the baby’s mouth and nose.

• The baby’s body can remain in the water to maintain warmth, unless the baby’s condition dictates otherwise. (Note: babies born in water may take slightly longer to establish respirations than those born into air. Maintain close observation of colour, heart rate and respirations.)

• Third stage should be managed physiologically as for any other low risk birth. If oxytocin is required or third stage is prolonged the woman is assisted to leave the bath/pool.

• Midwives must ensure that baths and pipes are thoroughly cleaned after use.

Watford General Hospital: Cleaning & disinfecting water birth pool and surrounding area

Posted on by K.D.Brainin

Watford General Hospital

Before use

The pool needs to be cleaned every 24 hours, as per instructions below. On completion The Pool Cleaning Record is signed by the member of staff performing the procedure.

Prior to each use and every 24 hours (to coincide with the daily pool cleaning), the pool taps need to be run for 2 minutes, as per water flushing guidelines.

After Use

1. Use the standard infection control precautions (plastic apron, disposable gloves and eye protection) when cleaning the pool. Ensure the area is well ventilated.

2. Remove any debris from the pool, using the sieve, before emptying the pool (to prevent debris blocking the pool outlet). Please ensure the thermometer has been removed from the pool prior to empyting the pool, in order not to block the pool outlet.

3. Use a non-abrasive detergeant to clean the pool of any further debris and blood; ensure the tap is cleaned first, so as not to transfer micro-organisms from the “dirty” pool area to the cleaner tap region. Please see guidance on cleaning sinks/basins and taps below. Rinse well with warm water.

4. Ensure the pool tap outlet is turned to “closed” prior to cleaning the pool tap and pool area with the chlorclean solution (2 tablets in 2 litres of cold water).

5. Clean the pool tap first prior to cleaning the pool with the chlorclean solution, as above.

6. When cleaning the pool itself, pour the chlorclean solution around the side of the pool. Using a clean disposable mop head/cloth, clean the surfaces of the pool and leave the solution in the pool for 10 minutes. Discard this mop head.

7. Open the tap outlet and empty the pool of the chlorclean solution.

8. Using cold water, rinse the tap then the pool to remove all traces of the chlorclean solution, to prevent any residue being left on the pool surface.

9. Dry the entire surface of the pool using a clean cloth or fresh disposable mop head. the pool is dried ensure the mop bucket asigned for cleaning the pool is cleaned and dried throroughly. Store it with the mop handle in room 8. Ensure all disposable mop heads used are disposed of in a yellow clinical waste bag.

11. Ensure the outside of the pool, window ledges, sink and its tap are cleaned with a chlorclean solution.

12. To clean the equipment (sieve, pool thermometer, mirror) used: wash and rinse these in warm water. Then soak for a minimum of 30 minutes in a chlorclean solution (2 chlorclean tablets in 2 litres of cold water), to cover equipment. After this, rinse and dry the equipment before placing these on a clean inco sheet on the top of the delivery box.

13. Finally, after the pool room has been restocked of equipment, towels, draw sheets etc, the floor is mopped using a chlorclean solution and a separate mop/bucket supplied by Medirest.

Guidance on cleaning of sinks/basins and taps in West Hertfordshire Hospitals NHS Trust
(to minimise risk of Pseudomonas aeruginosa)

Step 1 – cleaning the surrounding area

All basins, sinks and surrounding areas should e free from clutter and debris:

• Put on disposable gloves and apron
• Using a new disposable cloth and detergeant damp-clean the paper towel holder, then the soap dispenser, paying particular attention to theunderside of the soap dispensing unit, finishing with the nozzle.
• Then clean the underside of the sink/basin working from the higher level downwards.
• Carefully dispose of the cloth into the appropriate waste bag.
• Dry all surfaces with disposable cloth/towel as above.

Step 2 – Cleaning the wash-hand basin

• Using a new disposable cloth and sanitiser clean tap(s) first – start at the tap outlet end (do not put the cloth into the tap outlet), finish at the base and then clean tap handles.
• Then clean around the inside of the sink/basin from top rim of bowl, then overflow and waste outlet (do not put cloth into the overflow or waste outlet)
• Rinse as above
• Carefully dispose of cloth in appropriate waste bag.
• Dry all surfaces with disposable cloth/towel as above
• Dispose of gloves and apron in appropriate waste bag and decontaminate hands between the cleaning of each sink.

Guidelines for a safe water birth

Posted on by K.D.Brainin

Barbara Harper 2006

The aim of this guideline is to provide a review of information on labor and birth in water and to suggest possible strategies to minimize the potential hazards to mothers and infants.

It can also be used to promote the maternal and infant benefits, which may arise from choosing this type of birth experience, but are not easily quantifiable.

It is written with the belief that clinically sound, evidence based guidelines improve quality of care.

These recommendations are not intended to dictate an exclusive course of management or treatment.

They must be evaluated with reference to individual client’s needs, resources and limitations unique to the place of birth and variations in client choices.

Rationale

The therapeutic properties of warm water immersion have been known for centuries. Baths, showers and whirlpools have been used for comfort during labor for many years. Over the past two decades the use of warm water immersion for the birth of the baby has aroused interest in many countries and an increase in the number of women requesting this option for both hospital and out-of-hospital births is occurring.

Waterbirth International has reviewed the best available evidence and offers this guideline to assist midwives and women in their decision making process around the use of water immersion for labor and birth. The body of evidence is small but growing.

Evidence

Maternal and neonatal outcomes after water immersion for labor and birth have been assessed in two large surveys over a four year period in England and Wales (Alderdice, Renfrew & Marchant, 1995; Gilbert & Tookey, 1999) Researchers reviewed 4693 and 4032 births, respectively, where water immersion was used and found no difference in outcomes for women and their newborns compared to a cohort group of low risk women who did not use water.

The perinatal mortality rate for these births was comparable to other low risk births in the UK. (Gilbert and Tookey 1999). This study tried to estimate mortality and morbidity rates for babies delivered in water.

The data collected was compared to other sources of data providing similar estimates for babies delivered conventionally to low-risk women. They examined adverse outcomes, which were reported over a two-year period between 1994 and 1996 from approximately 4,000 births in water. 1500 consultant pediatricians were surveyed and asked to report any cases of baby deaths associated with waterbirth. None of the five perinatal deaths recorded among the waterbirths was attributable to delivery in water.

Admissions to special care baby units were slightly lower for the water-born babies than admissions for other low-risk babies. This was a landmark study in providing significant reassurance about the safety of waterbirth.

Other researchers (Burns 2001; Lenstrup et al, 1987; Rush et al,1996; & Waldenstrom et al, 1992) have made similar outcome reports. A recent Canadian randomized control trial reported women experienced less pain after water immersion than their non-immersion counterparts and over 80% of the water immersion group said they would use the tub in subsequent labors (Rush et al, 1996).

There have been a few highly controversial reports in the literature, especially in the journal Pediatrics on the negative effects of water immersion for babies. “Water Birth: a near drowning experience (Nuygen et al, 2002) suggests that every case of waterbirth should be evaluated as a possible fresh water drowning. The authors’ conclusions that the use of water for labor and birth may contribute to adverse outcomes should be viewed with considerable caution.

There are several methodological problems with this case study and these results are not congruent with the findings of many large trials. It is clear more research is needed into this form of care. But opinion pieces should be viewed at just that, opinion and not referred to as scientific or medical evaluation of the evidence.

In the absence of a substantial body of evidence on the use of warm water immersion for labor and birth, the potential advantages and disadvantages, which follow, are primarily derived from experience. This guideline will be updated as more evidence becomes available.

Eligibility

Water immersion for labor and birth should be available to all clients who request it, who have been screened and who have discussed the risks and benefits with their care provider. Some practices may choose to use a standard informed consent form for the use of warm water immersion.

Water Immersion Defined

Water immersion must be defined at providing a depth of water which enables the mother to sit in water that covers her belly completely and comes up to her breast level or kneel in water on her haunches which comes up to just below her breast level.

Any amount of water less than this does not constitute true immersion and will not create the buoyancy effect and produce the chemical and hormonal changes which enhance a more rapid labor. After an initial immersion of approximately thirty minutes the body responds by releasing more oxytocin, but only if the body experiences deep immersion, leading to buoyancy.

When to enter the bath in labor

It has been reported in the literature that labor slows down or stops if the woman enters the bath too soon. Guidelines were established to prevent a woman from entering the bath before the start of active labor, by definition: established labor pattern, dilation of the cervix to 4cm or greater and the need to concentrate during the contraction.

We argue that observation has led us to believe that a woman should be given the opportunity to use immersion as soon as her body and her brain have the desire to bathe. Women have been observed in very early labor relaxing, letting go of fear and progressing quickly to an active and pushing phase of their labor.

Using the water effectively often requires a “trial of water,” to see how the mother will respond. It has been noted with the advent of underwater continuous fetal monitoring that contraction patterns once thought to space out and become less frequent were in fact exactly the same in or out of the water. The mother’s response to those contractions in the water was vastly different from the response on the bed, thus making everyone believe that they were less intense.

The chemical and hormonal effects of immersion take effect after no less than twenty minutes and peak around ninety minutes. It is therefore suggested that a change of environment, such as getting out and walking be recommended after about two hours of initial immersion. The midwife can make an evaluation of the mother’s condition at that time.

Getting back in the water after thirty minutes will reactivate the chemical and hormonal process, including an sudden and often marked increase in oxytocin.
Dianne Garland, registered midwife, lead waterbirth researcher in England and the author of, ” Waterbirth: An Attitude to Care,” says the following:
” Just as labors can be slower or stop out of water so is true of water. Changes to the woman’s body are normal in labor and each of us will tolerate different lengths of first and second stage. Just as we all deal with different amounts of fatigue and stress, so each woman is individual and should be treated as such in labor.

The point of this with water labor and waterbirth is that as each woman is an individual, so her labor should be cared for, within the normal parameters set by ourselves as autonomous practitioners. Or within the maternity units where we work. Fundamental changes to normal practice may need to be made in units where active management of labor prevails.”

Summary of benefits for labor and birth in water

  • Facilitates mobility and enables the mother to assume any position which is comfortable for labor and pushing
  • Speeds up labor
  • Reduces blood pressure
  • Gives mother more feelings of control
  • Provides significant pain relief
  • Promotes relaxation
  • Conserves her energy
  • Reduces the need for drugs and interventions
  • Protects the mother from interventions by giving her a protected private space
  • Reduces perineal tearing
  • Reduces cesarean section rates
  • Is highly rated by mothers – typically stating they would consider giving birth in water again
  • Is highly rated by midwives
  • Encourages an easier birth for mother and a gentler welcome for baby

Theoretical Potential Disadvantages

  • Decrease in uterine contraction strength and frequency, especially if entering the bath too soon
  • Neonatal water aspiration
  • Maternal hyperthermia may contribute to fetal hypoxemia
  • Neonatal hypothermia
  • Cord immersion in warm water may delay vasoconstriction, increasing red cell transfusion to the newborn and promoting jaundice
  • Blood loss estimation and assessment not accurate
  • Maternal and Neonatal infection may be increase – not supported by the evidence
  • Risk of acquiring blood born infection or sustaining back injury for caregivers

    Recommended Criteria for the use of a water pool

  • An uncomplicated pregnancy of at least 37 weeks gestation
  • Established labor pattern – good regular contractions
  • Reassuring fetal heart tones
  • Absence of bleeding greater than bloody show
  • Spontaneous or on-going labor after misoprostol or Pitocin

    Contraindications for birth in a water pool

    There are no contraindications to labor in water, as evaluated by the literature and from experience. Immersion is a client/provider decision. Birth in water comes with a few “ABSOLUTE” contraindications and a few “CONTROVERSIAL” contraindications.

    Absolute contraindications

  • Pre-term labor
  • Excessive vaginal bleeding
  • maternal fever> 100.4, or suspected maternal infection
  • Any condition which requires continuous fetal heart rate monitoring
  • Untreated blood or skin infection
  • Sedation or epidural
  • Fearful Attendant
  • Inflexibility in the client

    Controversial contraindications

  • Meconium staining in amniotic fluid

    The presence of meconium should be evaluated with fetal well-being and taken by itself as a reason to ask the mother to leave the water. Meconium washes off the baby in the water. Baby can be suctioned as soon as it has been brought to the surface of the water. Some practices are now only limiting thick meconium cases.

  • HIV, Hepatitis A, B, C, GBS

    Evidence shows that HIV virus is susceptible to the warm water and cannot live in that environment. Proper cleaning of all equipment after the birth needs to be carried out. Hepatitis should be the discretion of the attending medical caregiver.
    There is absolutely no evidence that GBS positive cases should be asked to leave the water. Most hospitals allow IV antibiotic administration while in the water.

  • Herpes

    Some providers will cover the lesion, especially if it has peaked and is sloughing off. Others will require a cesarean. Some feel it is safer to deliver in the water due to the dilution effect of the water.

  • Breech or multiple births

    In the H. Surreys Hospital in Ostend, Belgium, frank breech is an indication for a waterbirth. Their vast experience has led them to believe that the absence of gravity, the warm water and the buoyancy create the perfect environment for a hands free breech birth. Labor in water for both breech and multiples is well documented and recommended. This should be a client/provider decision.

  • Shoulder Dystocia or Macrosomia with suspicion of Shoulder Dystocia

    This is usually considered an obstetric or midwifery emergency by most. Current protocols in most hospitals require the mother who is anticipating a large baby to leave the water. There is mounting evidence that providers find it is easier to assist a shoulder dystocia in the water. It is believed that tight shoulders happen more often because of mom or caregiver trying to push before the baby fully rotates. Better to wait a few contractions, with the head hanging in the water and allow baby to rotate. Because position changes in water are so much easier than dry land, a quick switch to hands and knees or even standing up with one foot on the edge of the pool helps to maneuver baby out. (research indicates that you can’t predict shoulder dystocia)

  • VBAC

    As the controversy over vaginal birth after previous cesarean section continues, it has been noted that mothers who labor for subsequent births have a much higher success rate in giving birth vaginally. Some hospitals refuse to allow women into the water because they don’t provide waterproof continuous fetal monitoring.

  • Intrathecal use

    A few hospitals will allow a mother into the water after receiving an intrathecal Monitoring of the baby is suggested as continuous, but some hospitals allow intermittent monitoring.

  • Induction or augmentation

    Many hospital practices will now allow mothers whose labors are initiated by Misoprostal or Pitocin to get in the pool as soon as a labor pattern is established.

    Some even allow mothers with a Pitocin drip to labor in water, as long as fetal heart rate assessment can be monitored with continuous underwater equipment.

  • Tight nucal cord

    Under no circumstances should the cord be clamped or cut under the water. Babies can be delivered through the cord and ‘unwound’ under the water. Be cautious of cord snapping.

  • Water temperature at time of birth

    Some providers will not allow women to birth in water that is lower than body temperature due to the possibility that the baby will attempt to inhale under the water from a change in temperature. There is no evidence that supports this theory, in fact there is more evidence that now shows that lower water temperatures increase the baby’s muscular activity and awareness.

    Water babies are slow to start breathing due to the delay in stimulation of the trigeminal nerve receptors in the face and around the nose and mouth. You must consider the birth of the baby from the time it leaves the water, not from the delivery of the baby into the water. German midwife, Cornelia Enning, states that babies are more vigorous at a temperature around 92-95 degrees Fahrenheit. If the mother is comfortable in the water, the temperature is OK for baby with only one restrictive parameter – NEVER higher than 100 degrees Fahrenheit.

  • Placental delivery in water

    There is no reason not to allow the birth of the placenta in water. Objections include inability to judge blood loss, possible water embolism and inability to contain all the by products of conception in one place. Evidence now shows that delivery of the placenta is safe, blood loss can be estimated by color evaluation and determination of where the bleeding is arising and there is absolutely no scientific basis for worry over water embolism. Placenta and pieces can be placed in a floating bowl in the water without difficulty. Cutting and clamping of the cord is not recommended with the delivery of the placenta in the water.

    Helpful reminders for the use of water immersion for labor and birth

  • Midwives should discuss the potential advantages and disadvantages of water immersion for labor and birth with each woman prior to labor.
  • The fetal heart should be monitored according to accepted guidelines. Use of a waterproof Doppler is recommended.
  • The woman should be encouraged to maintain adequate hydration and leave the pool to urinate at regular intervals.
  • The woman should be asked to leave the water if there are any concerns about her or her baby’s well being.
  • The water should be kept as clean as possible. Stool and blood clots should be removed from the pool immediately. The pool should be drained, cleaned and refilled if contaminants cannot be easily removed.
  • A small amount of blood often looks like a lot. Undisturbed blood in a pool often congeals at the bottom of the pool into a small clot.
  • The pool or tub should be deep enough for the mother to assume any position comfortably.
  • Encourage mother to help guide her own baby out.
  • Suturing may need to be delayed due to water saturation of tissues.
  • The baby should be born completely underwater with no air contact until the head is brought to the surface, as air and temperature change may stimulate breathing and lead to water aspiration. If a change in position during delivery causes the baby to come in contact with air, the birth should be finished in the air.
  • Care should be taken to avoid undue traction on the cord. There have been reports of cord tearing.
  • The warm water helps maintain the newborn’s temperature to prevent hypothermia. Keep baby submerged with head out only for best heat conservation. Next to mother is best.
  • Encourage breast contact immediately, but breastfeeding is not always possible in the water, especially due to water high water levels.
  • You can insert a footstool or other object (husband) to raise a mother up high enough after the birth.
  • Birth pools should be cleaned completely between uses with a chlorine-releasing agent. All pumps and hoses should also be rinsed with bleach.
  • Outdoor hot tubs are OK to use for labor and birth, if they are cleaned and maintained prior to the labor.
  • Jetted pools are ok to use if they are cleaned properly between patient use.
  • Small amounts of chlorine or bromine are not harmful to mothers or babiesAs when caring for any mother or newborn, the midwife is responsible for using her clinical judgment, responding appropriately to problems that may arise, and for documenting her actions.
