Neuraxial opioids for labour analgesia: analgesic efficiency and effect on labour

Abstract

Neuraxial opioids have changed the practice of obstetric anaesthesia and analgesia dramatically. Excellent analgesia with minimal side effects started an era of ever increasing numbers of women who opt for the 'painless birth experience'. Several papers have been reported during 2001 that examine analgesic efficacy, maternal side effects, and effect on foetal well-being of epidural and spinal opioids. Foetal bradycardia following intrathecal opioid analgesia, an increasingly popular technique, has attracted particular attention over the past few years. The present review addresses recently reported work that, according to the author, is key to this field.
