Induction Of Labour

Induction of Labour

How it works

Most women enter labour naturally at around the 40 week mark of their pregnancy. However there are some situations where it becomes necessary to artificially begin the process of labour, for the safety of the mother or child.

Prostaglandin’ is a hormone-like substance which can be administered to induce labour, as it causes the cervix to ripen and can stimulate uterine contractions. Prostaglandin is applied as a gel or pessary, which causes the cervix to soften and open. If the gel is applied, it may have to be reapplied every 6 to 8 hours, while the pessary will continue to release Prostaglandin. Once the Prostaglandin has taken effect and the cervix has softened, labour may start naturally or require further action.

Prostaglandin may cause soreness in some women but it is not known to make pregnancy more painful than a natural birth. Prostaglandin can be associated with nausea, vomiting and diarrhoea. In very rare instances, Prostaglandin can result in uterine contractions, which carries some risks of affecting a baby’s heartrate.

If Prostaglandin does not assist to start the labour process naturally, further action might be taken by administering a chemical called ‘Syntocinon’. Syntocinon is a synthetic version of the chemical ‘Oxytocin’, which is naturally produced by the body and plays an important role in labour and childbirth.

Administering Syntocinon increases activity in the uterus, which can start the labour process or cause stronger contractions in active labour. Because of this, the administration of Syntocinon requires constant monitoring and carries significant risks, so it should not be undertaken where it is not required.

Risks of chemically induced labour

Although expediting labour can be highly beneficial, it comes with significant risks. Syntocinon affects the speed of the fetal heartrate and abnormalities in fetal heartrate can lead to various developmental disorders. Because of this, Syntocinon or other chemicals used during induction of labour should only be administered where there is a clear benefit to both the mother and baby and when fetal heartrate monitoring is available, to avoid danger or injury to the baby.

If too much Syntocinon is administered, contractions may become too frequent and fetal distress may occur. This happens when there isn’t enough oxygen reaching the baby and can lead to serious damage to organs – including the heart and brain – during labour and delivery. Fetal distress will usually necessitate a caesarean section, to prevent problems caused by the lack of oxygen.

If the baby has not yet reached full-term when labour is induced, it faces the same health risks as any other preterm baby. It has also been reported that induced labour is more painful than spontaneous labour and can result in further medical intervention during the labour process.

Other drugs used in labour

Terbutaline’ is another chemical used during labour, although it is commonly used to counteract the effects of Syntocinon or other labour inducing drugs. Terbutaline slows uterine activity and delays labour, eg. where a child would be delivered preterm or the fetal heartrate needs to be slowed. Like Syntocinon, an overdose of Terbutaline can cause problems for the baby. Slowing the fetal heartrate too much can cause ongoing heart and brain disorders and has also been found to cause heart problems for the mother.

Our Experience

We have conducted many cases over the years involving children with ongoing disabilities due to negligence in administering labour inducing drugs.

Legal issues which arise in this area include:

  • Whether amount of Syntocinon or Terbutaline administered was appropriate.
  • Whether the fetal heartrate was adequately monitored during this procedure.
  • Whether steps were taken quickly enough to remedy any potential overdoses identified.
