Delayed Cord Clamping Safety, Benefits & Side Effects

July 11, 2024

A baby in the mother’s womb receives blood, oxygen, and nutrition through the umbilical cord. The umbilical cord is the connection between the fetal body and the placenta which is attached to the uterus. It is also how the baby’s wastes are discarded. After birth, the baby is out in the world, and the body learns to function independently. There is no more need for the umbilical cord to sustain the baby’s life. So, the doctor clamps the cord and cuts it soon after birth. In some cultures, cutting the cord is a special procedure that the father or someone important to the mother does.

Did you know that only some people follow this? Some prefer to delay the baby cord clamping and cutting. Read on to learn all about delayed cord clamping.

What is Delayed Cord Clamping?

Delayed cord clamping is nothing but delaying the clamping and cutting of the umbilical cord immediately after birth. The blood and nutrients keep flowing from the placenta to the foetus while inside the mother and will continue to do so for a few minutes after delivery.

In delayed cord clamping, the doctors wait 60 seconds before clamping and cutting the umbilical cord connecting the baby to the placenta. Due to this delay, the baby gets more oxygenated warm blood from the placenta even after the delivery. It helps transfer about 80 ml of blood from the placenta to the baby.

How is Delayed Cord Clamping Done?

Until recently, doctors would clamp the umbilical cord close to the baby’s naval and cut it immediately after birth. This will stop the blood transfer from the placenta to the baby. Since the blood flows from the mother to the baby through the placenta, it was always thought cutting the cord as early as possible prevented unnecessary blood loss in the mother.

Recent research and studies showed that giving time for the blood in the placenta, which is already en route to the baby, will help the baby rather than cause any harm. So, the doctor will wait between 30 seconds to even 1 minute, in some cases, to cut the cord after the delivery.

Advantages of Delayed Cord Clamping

Today, with more research and awareness about the benefits of delayed cord clamping, many hospitals follow this as a standard birthing procedure.Delayed cord clamping has many advantages, such as:

  • For full-term babies, giving the extra time before cutting the cord allows the newborn to receive more iron and reduces the risk of anaemia.
  • In preterm babies,delayed cord clamping increases blood circulation time and the baby’s red blood cell volume. (But 30 secs only given)
  • It also reduces the risk of necrotizing enterocolitis and intra ventricular haemorrhage.
  • It helps in transferring more immunoglobulins and stem cells to the baby. This helps repair cellular injury and reduces inflammation and organ dysfunction, which are common in preterm births.
  • Decreases risk of iron deficiency or anaemia in the baby

What are the Disadvantages of Delayed Cord Clamping?

Sometimes, even the best practices may be unsafe during pregnancy and delivery. Complications arise when you least expect them. Some possible disadvantages of delayed cord clamping are:

  1. Polycy themia – Polycy themia is a condition where there are excess red blood cells in circulation in the body. A lot of red blood cells in circulation is not always good news. These extra red blood cells in circulation can cause breathing or circulation issues and lead to hyper bilirubin inemia.  
  2. Hyper bilirub inemia –When there is a high level of red blood cells in circulation, it can break down and release bilirubin. It can then build up and lead to hype rbilirub inemia. During pregnancy, the placenta is responsible for managing any excess bilirubin. However, the baby’s liver must take care of it after birth. Since the liver is just developing, processing all the excess bilirubin may be challenging, leading to jaundice in the baby.
  3. Hyper viscosity – When there is too much blood flowing into the baby’s body, it can increase the blood thickness.
  4. Respiratory Distress – If the baby’s lungs do not have a sufficient liquid coating to keep the airways open after birth, it can damage cells. Over time, it can build up damaged cells and carbon dioxide in the blood, which can be very dangerous.
  5. Haemorrhage – Delayed cord cutting can lead to postpartum haemorrhage in some mothers. (Oxytocics are given a bit late so)

However, there is not much evidence about the risks ordis advantages of delayed cord clamping. These are just possible risks associated with delayed cord clamping. Sometimes, the doctors wait just a few seconds, and it hardly makes any difference to the earlier method of cutting the cord.

How Long Should You Wait to Cut Umbilical Cord?

Each hospital or doctor has its way of delaying cord clamping. They can delay the clamping and cutting by 30 seconds to even 2 full minutes.(60 seconds mainly) The intention is to increase the benefits to the baby without endangering the mother in any way.

Is it Good to Delay Cord Clamping?

Yes, it is the procedure followed by most hospitals today. Remember, delayed cord blood clamping is not always the best method to deliver a baby. Depending on various factors, doctors decide what to do or not to do during the baby’s delivery.

When is Delayed Cord Clamping Not Advisable?

Delayed cord clamping is not advisable in the following situations

  • The infant is in a state of distress and requires urgent medical assistance.
  • The mother is in danger and needs treatment immediately.
  • Mother starts losing too much blood.
  • The baby is not breathing or responding to initial stimulation after delivery.
  • If there is placent aprevia or placental abruption.
  • If mother is RH negative

Conclusion

Delayed cord clamping has more advantages than disadvantages. When done correctly by an experienced doctor, it can be safe and beneficial for the baby. The baby or the mother will not be harmed if cord clamping is not delayed because of any issue.

FAQs

Is delayed cord clamping compulsory?

It is not compulsory but is followed in most hospitals due to its advantages. While some doctors wait for just 30 seconds, others wait up to 5 minutes.(Recommended is 60 seconds)
