Brief Summary

Childbirth can be an extremely painful and the provision of pain relief during labour is a vital component of a positive maternal experience. The majority of women who deliver in modern obstetric units choose a pharmacological method of pain relief, including Entonox, the injection of opioids or epidural placement. The commonest opioid used in labour is pethidine administered by intramuscular (im) injection. The effectiveness of pain relief provided by pethidine has long been challenged. Its shortcomings are more serious when set against known side effects including maternal sedation, nausea and potential transfer across the placenta to the foetus. More than a third of women who receive pethidine subsequently require an epidural due to inadequate pain relief. Epidurals provide highly effective pain relief, but increase the risk of a forceps or suction delivery resulting in prolonged hospital stay. Therefore, there is a clear need for a safe, effective, easy to administer analgesic alternative.

Study Arms (2)

Pethidine

ACTIVE COMPARATOR

Pethidine is pain relief in labour

Drug: Pethidine

Remifentanil

ACTIVE COMPARATOR

Remifentanil intravenous patient controlled analgesia

Drug: Remifentanil

Interventions

100mg by intramuscular injection, up to 4 hourly in frequency (up to a maximum of 4 doses). The maximum dose being 400mg in 24 hours.

Also known as: Meperidine
Pethidine

Dedicated intravenous cannula for remifentanil administration PCA protocol * PCA bolus remifentanil 40 μg * Lockout interval 2 minutes In the event of excess sedation being recorded by regular observation of respiratory function, the regimen will be altered by reduction of the remifentanil bolus dose to 30 μg with a lock-out interval of 2 minutes.

Also known as: Ultiva
Remifentanil
