Cutting the cord! For some birth partner’s it’s a rite of passage, for other’s they’d rather hand it over to the midwife! We’ve often thought about WHO’s going to ‘cut the cord’, but have you given any consideration as to WHEN they’re going to cut it?
After your baby has been born, it will still be attached to the placenta, by the umbilical cord. The placenta is still providing oxygenated blood to the baby until it has stopped pulsating (approximate 3-5 minutes after birth). After that, the placenta will detach from the uterus and be born.
Did you know? There’s usually no need to cut the cord before it has stopped pulsating, or even before you have birthed the placenta.
Early cord clamping became commonplace in the sixties following the introduction of new drugs in an attempt to prevent too much maternal bleeding after birth. Thought this was never based on any evidence!
Following more recent research, The World Health Organisation now recommends waiting until the cord has stopped pulsating before cutting, usually between 3-5 minutes. But why? I’ve summarised the evidence into bitesize chunks, which will hopefully help you make your decision.
A Summary of the Evidence
What are the benefits?
- Baby continues to receive oxygenated blood until breathing is established and this has been shown to reduce the chances of any breathing difficulties (particularly in preterm infants).
- Around 1/3 of the baby’s blood remains in the placenta at birth. Allowing this to transfuse into e baby where it belongs, can lower the risk of anaemia or compromised heart function.
- Optimal Cord Clamping reduces the risk of late onset sepsis and the need for a blood transfusion in preterm babies.
- There is a reduced chance of Mum having a retained placenta (where the cervix closes before the placenta has been born).
But, what are the Risks?
- A small study has shown a slightly increased risk of baby developing jaundice following delayed cord clamping, though usually physiological (normal) and most experts agree that the benefits outweigh the risks in this case.
Current guidance in the UK recommends OCC for all births, unless there is a medical reason to cut the cord sooner. If you are planning an ‘active third stage’, where your placenta is helped out through an injection of synthetic oxytocin, you can still have OCC, but they recommend the cord is cut before 5 minutes.
Though it is written into the guidelines, it’s still worth putting into your own birth plan if it’s important to you.
As with any choice you make around pregnancy and birth- gather the information, weight up the risks and the benefits and make a decision that feels right for you and your baby!
