Wait! Don’t cut your baby’s cord too soon!

Preparing for birth involves knowing about the third stage of labour (birthing your placenta). At the time of birth, the placenta continues to function pumping blood to the baby (Enning 2007) but eventually the umbilical cord stops pulsing and the placenta will need to be birthed.

In many Australian hospitals it is quite common for delivery of the placenta to be ‘managed’. This involves an injection of synthetic oxytocin. A natural third stage (without drugs being used) is called a ‘physiological third stage’. It is also quite common to clamp the cord soon after birth, however, there is no sound scientific evidence that supports the immediate clamping in vaginal or cesarean births (Emerson 2012).

The World Health Organization states that even if you want/need the synthetic oxytocin injection, you can still leave the baby attached to receive the benefits of delayed cord clamping (Cernadas 2006).

These photos were taken by Nurturing Hearts Birth Services and show how the cord visibly changes as the blood transfers to the baby after birth.

What does it mean to delay cutting the cord?

According to Abalos (2009) an exact definition of ‘delayed’ cord clamping is unclear, however, it is generally understood to mean a delay of cutting the cord until 2-3 minutes after birth or when the cord has stopped pulsing.

What are the benefits of delayed cord clamping?

  1. At the time of birth, up to one-third of the baby’s blood volume is still in the placenta (Buckley 2009). By allowing the cord to finish pulsing, the baby will receive most or all of its blood. This extra blood contains iron, oxygen and stem cells and is beneficial for the baby to receive it! Stem cells may even help with recovery from the birth (Reed 2015).
  2. Gentle transition to earth: It’s a big transition to make from womb to world. The baby needs to initiate breathing and this can take a little time. By leaving the cord unclamped, the baby can continue to receive oxygen from the placenta via the pulsing umbilical cord (Buckley 2009). This gives the baby time to expand it’s lungs and get used to breathing on it’s own (before this oxygen supply is removed).
  3. Keeping mother and baby close to each other helps with bonding and helps the mother to release her own natural oxytocin which helps prevent post-partum hemorrhage and helps her to safely birth the placenta (Buckley 2009).

A 2013 Cochrane review (McDonald et al) found “There are some potentially important advantages of delayed cord clamping in healthy term infants, such as higher birthweight, early haemoglobin concentration, and increased iron reserves up to six months after birth. These need to be balanced against a small additional risk of jaundice in newborns that requires phototherapy.”

When is a good time to cut the cord?

Dr Sarah Buckley (2009) recommends delaying the cord clamping for as long as possible and ideally after the mother has birthed the placenta. If this is not possible, then consider waiting until:

  1. After the baby takes its first breath
  2. After 30 seconds from birth
  3. After 3 minutes or so after birth
  4. After the cord stops pulsing

World Health Organisation (2013/2014) recommends:

Waiting to cut the cord until at least one to three minutes after birth or after the cord stops pulsating. This leads to improved infant and maternal health.

When does the cord stop pulsing?

Did you know you can actually feel the cord pulsing? It feels like a pulse through a thick udon noodle. According to Dr Rachel Reed (2015), textbooks will tell you it stops pulsing between 3-7 minutes, but she has felt cords pulse for longer than that.

Hold the baby below the placenta

Once the baby is born, where it is placed (ie; on mothers chest) will impact how quickly the placenta can transfer the extra blood. If the infant is held below the level of the placenta, then this accelerates the transfusion of blood from placenta to baby (Buckley 2009). For a baby who is being held skin-to-skin on the mothers chest, a five minute delay will allow enough time for the baby to receive all its blood from the placenta (Mercer and Erikson-Owens 2012).

Cesarean births

According to Dr Buckley (2009), several studies have shown that respiratory distress can be eliminated (babies can establish breathing easier) when they have been allowed to receive their full placental transfusion (their full blood supply from the placenta).

In a cesarean birth, it’s possible to request that the doctor wait until your baby takes its first breath before cutting the cord. The baby can also be positioned lower than the placenta and the blood can be ‘milked’ from the cord to the baby to help it establish breathing and receive it’s normal blood volume (Emerson 2011).

So, when writing your birth preferences, be sure to include your ideas surrounding delayed cord clamping and make sure your care provider knows your wishes!
