Delayed cord clamping
Delayed cord clamping – or optimal cord clamping as it is starting to become known – is when a delay is made between a baby being born and its umbilical cord being clamped and cut. This delay is considered anything from around a minute or longer. This has been discussed much in the press in 2015 as many important institutions have recognised studies that show that delayed cord clamping has huge benefits and adjusted their guidelines accordingly.
Early cord clamping
It is fairly routine in western society to clamp and cut a babies cord immediately after birth (within seconds) but it is a relatively recent phenomena and, as we are discovering, it is not remotely evidence-based.
Historically, evidence can be found of early cord clamping (ECC)as early as the 1600s but really only took hold as a routine procedure from about the 1960s, touted as a way to reduce post-partum haemorrhage (PPH) in mothers.
It can also been seen to help reduce the incidence of jaundice due to a reduction of bilirubin in the baby’s blood – however, there has been no evidence of this link found and anyway, jaundice in itself is not a life-threatening condition in most cases especially when treated in a western country.
Here is a lovely blog post detailing how this baby was resuscitated with the cord intact and the placenta providing blood to the baby while the medical team helped baby.
Baby’s blood at birth
At birth around one third of the baby’s blood is in the placenta. In the few minutes immediately after birth, the placental blood is transfused into the baby, stimulating it’s heart and lungs and helping its organs start working independently. As the baby’s body takes over its life support from the placenta, the blood transfer between the baby and placenta equalises, the wharton’s jelly that surrounds the veins and artery inside the cord starts to solidify, and the cord starts to naturally close off.
Early clamping of the umbilical cord means that this extra 33% of the baby’s blood is not getting to the baby.
Here is a great video that shows you the volumes of blood involved and the equivalent amounts for an adult
Stop the mess!
In fact the only reason why the cord is clamped is because it is being cut too early when blood is still present. So if it isn’t clamped you get blood all over the floor as the placenta is still trying to pump the blood into the baby!
So why do we do it?
Benefits to the baby
There have been studies – some of which are linked to below or linked to articles that reference them – that show many benefits to the infant when delayed cord clamping happens.
- Improved iron levels up to 4-6 months (depending on study)  which resulted in
- Significantly better personal-social and fine-motor functioning at 4 years old 
- lower risk of brain bleeds 
- Gives baby all the blood they need
- Helps stimulate organs at birth
- Helps achieve successful natural third stage (delivery of placenta)
What if my baby need resuscitating?
There is growing consensus that even if a baby requires resuscitation then it should be done next to the mother before the cord is clamped – after all, the cord is supplying the baby with oxygen so it seems pretty daft to cut off it’s life-line!
The UK Resuscitation council guidelines state that:
At present there is insufficient evidence to define an appropriate time to clamp the cord in babies apparently needing resuscitation. However, this may be because time is the wrong defining parameter and perhaps the cord should not be clamped until the baby has started breathing.
What should the cord look like?
Delayed cord clamping of one or more minutes allow the blood to pump into the newborn and after 5+ minutes the cord will stop pulsating as the blood transfer eases off. It will start by looking very thick with dark veins inside, and end up looking thin and white.
There is also a wonderful birth photographer who has compiled photos of intact cords left to empty themselves of blood, check out her blog post.
Who else agrees?
In the 6 months between Dec 2014 and June 2015 3 major institutions have changed their guidelines in the face of this evidence.
UK Resuscitation Council Guidelines 2010
- Delayed clamping by at least one minute in healthy term infants, but ideally up to 3 minutes or until the cord has stopped pulsating.
NICE Guidelines Dec 2014
- Do not clamp the cord earlier than 1 minute from the birth of the baby unless there is concern about the integrity of the cord or the baby has a heartbeat below 60 beats/minute that is not getting faster.
- If the woman requests that the cord is clamped and cut later than 5 minutes, support her in her choice. [new 2014]
WHO guidelines Jan 2015
- Delaying cord clamping allows blood flow between the placenta and neonate to continue, which may improve iron status in the infant for up to six months after birth.
RCM Guidelines April 2105
- The paper states that immediate cord clamping reduces the flow of blood to the baby and can deprive the baby of iron. Iron deficiency in the first few months is associated with neurodevelopmental delay.
- Looking at existing evidence for term births, the paper looks at the Cochrane review, which concluded that the evidence justifies a more liberal approach to delaying clamping of the cord, as long as access to treatment for jaundice is available.
- Once delivered, the baby can be placed on the mother’s abdomen or chest with the cord intact and the timing of clamping should be recorded
There are a thousand books on how to have a natural birth with different techniques and methods. Very few of them address the reality that over 50% of mothers in the UK have some form of intervention or birth pain relief in childbirth, and the number is...
What are birth interventions. On the whole, birth interventions are not usually planned for in early pregnancy. However, the two major interventions many parents face are an induction of labour or caesarean. In many cases, birth interventions are required for medical...
Pain Relief vs Natural Birth When preparing for birth, most women's first instincts are to find out all they can about natural birth and not really consider labour pain relief. We have done it for millions of years, after all, and the excitement that...
Clary Sage Oil Clary sage oil is often touted as an effective method to induce labour naturally and enhance contractions once labour has started. The reality is that babies come precisely when they are ready. Studies have shown that labour is triggered once the baby's...

TENS Machine in Labour Most women don't like the idea of using pain relief in labour and so any methods that are side-effect-free are a bonus. There are many things you can do in labour to minimise the pain and using a TENS Machine in labour is a popular...

Allowing The Impossible in Birth You often hear the question "am I allowed" asked in the context of birth, particularly in the hospital setting. Am I allowed to get off the bed? Am I allowed to have something to eat? Am I allowed to change position?...
Birth is everywhere! Everyone is born, after all, and 4 in 5 women will go through the experience (1). For some, giving birth is a wonderful life-affirming event - even describing it as orgasmic! - but for many women, labour and birth is painful, difficult...
