Extending low-dose epidural analgesia for emergency Caesarean section using ropivacaine 0.75%.
We compared ropivacaine 0.75% and bupivacaine 0.5% for extending low-dose epidural analgesia for emergency Caesarean section, using a prospective double-blind randomised controlled trial design. The trial was halted after 45 patients were studied (23 ropivacaine; 22 bupivacaine) because bupivacaine was replaced by levobupivacaine in our unit. Time to reach T4 for loss of cold sensation was similar in both groups, although analgesic supplementation was required less often in the ropivacaine group than in the bupivacaine group (2/23 vs. 9/21; p = 0.01).
