## Direct answer

Precipitate labour is labour completed rapidly, usually within about three hours of onset, with high risks of maternal trauma and fetal injury. It is often seen in a multiparous woman with a previous rapid labour, or after hyperstimulation from oxytocin or prostaglandins. The main hazards are lacerations, postpartum haemorrhage and intracranial haemorrhage in the baby, so management focuses on controlled delivery of the head and neonatal readiness.

## What you must remember

- **Definition:** labour completed in roughly three hours or less from onset, though some definitions use shorter limits.
- **Causes:** high parity, a previous rapid labour, strong uterine action and hyperstimulation from oxytocin or prostaglandins.
- **Maternal risks:** cervical, vaginal and perineal lacerations, postpartum haemorrhage and, in a scarred uterus, uterine rupture.
- **Fetal risks:** intracranial haemorrhage, birth trauma and hypoxia, since the head undergoes rapid compression and sudden decompression.
- **Delivery setting:** an unplanned delivery at home or in transit increases both maternal and neonatal risk.
- **Prevention:** women with a previous precipitate labour are counselled to plan delivery in a unit with skilled staff and neonatal services.
- **Management:** stop oxytocin, check the trace for tachysystole and prepare for a controlled delivery with neonatal resuscitation at hand.

## A sequence for managing a rapid delivery

Precipitate labour is short, so the steps must be fast and predictable. The order below matches how an obstetrician should work through the situation once it is recognised.

1. **Recognise the pattern early.** Rapid contractions with fast cervical change, or a history of rapid previous labour, flags the risk before delivery.
2. **Check uterine activity.** If oxytocin or a prostaglandin is running, stop it, and check the CTG for tachysystole and fetal response.
3. **Consider tocolysis.** A tocolytic may be used to slow contractions when hyperstimulation is evident and delivery is not imminent, under obstetric judgement.
4. **Prepare for delivery.** Summon the midwifery and paediatric teams, prepare resuscitation equipment and move the woman to a suitable room.
5. **Control the head.** Support the perineum and deliver the head slowly, so that sudden extension and rapid pressure change are limited.
6. **Check for bleeding and tears.** Inspect the genital tract, repair tears promptly and manage the third stage actively because of the haemorrhage risk.

## Where the exam tries to catch you

Questions test whether the candidate recognises the hazard in a fast labour and acts before delivery rather than after.

- **Trap:** continuing oxytocin when contractions become very rapid — **Correct:** oxytocin is stopped and hyperstimulation is assessed, since rapid contractions raise the risk of trauma and fetal compromise.
- **Trap:** assuming a fast labour is always benign because it was quick — **Correct:** rapid labour increases the risk of intracranial haemorrhage and lacerations, so both mother and baby need assessment.
- **Trap:** pushing the head out quickly to save time — **Correct:** controlled delivery of the head protects the perineum and lowers the risk of a severe tear and fetal trauma.

## Frequently asked questions

### What is the usual definition of precipitate labour?

Precipitate labour is usually defined as labour that is completed within about three hours of onset. Definitions vary, and some use shorter time limits. The defining feature is a rapid delivery that carries risks for both mother and baby.

### Which fetal complication is most feared in precipitate labour?

Intracranial haemorrhage is the most feared fetal complication in precipitate labour, because rapid compression and sudden decompression stress the fetal head. Hypoxia and birth trauma are also risks. A neonatal resuscitation team should be ready at delivery.

### Why is precipitate labour dangerous for the mother?

Precipitate labour is dangerous for the mother because rapid delivery causes lacerations of the cervix, vagina and perineum. It increases the risk of postpartum haemorrhage and, in a scarred uterus, uterine rupture. An unplanned home delivery adds to these risks.

### How is a woman with a previous precipitate labour counselled?

A woman with a previous precipitate labour is counselled to plan delivery in a unit with skilled staff and neonatal services. Early admission and close monitoring are usually advised once labour starts. The plan reduces the chance of an unplanned delivery at home or in transit.

### Should oxytocin be stopped in precipitate labour?

Oxytocin should be stopped in precipitate labour when uterine hyperstimulation is suspected, because strong, frequent contractions raise the risk of trauma and fetal distress. The CTG is checked for tachysystole and the fetal response. Restarting the drug depends on the clinical picture.
