Labour is an extremely painful process. Labour pain is of major concern since most parturients experience significant pain of extremely severe intensity. Labour pain can have deleterious effects on the mother, on the foetus and on the labour outcome. Among the current methods of obstetric analgesia, regional analgesia (the most widespread technique being epidural analgesia) offers the best effectiveness/safety ratio. We conducted this study to compare the efficacy of a mobile epidural using 0.0625% bupivacaine and 0.0002% fentanyl versus a conventional epidural using 0.125% bupivacaine for labour analgesia.
