A continuous subdural block

Abstract

We describe a case of accidental subdural block, after attempted extradural puncture for Caesarean section. Fractionation of the local anaesthetic dose led to avoidance of more serious complications. Subdural fentanyl and a continuous low-dose subdural infusion were used satisfactorily for intra-operative management and postoperative analgesia. As little as 0.5 ml of bupivacaine, hourly, provided satisfactory analgesia over a 15-h period. (Br. J. Anaesth. 1993; 70: 462-465). © 1993 British Journal of Anaesthesia.
