Combined spinal-epidural analgesia vs. intermittent bolus epidural analgesia for pain relief after major abdominal surgery. A prospective, randomised, double-blind clinical trial

Abstract

Combined spinal-epidural improved intra-operative analgesia and reduced pain with cough in the immediate postoperative period. The addition of fentanyl to subarachnoid morphine and bupivacaine decreased the need for additional i.v. fentanyl and epidural bupivacaine analgesia.
