A Comparative Study for Post Operative Analgesia in the Emergency Laparotomies: Thoracic Epidural Ropivacaine with Nalbuphine and Ropivacaine with Butorphanol.

Background: Adequate postoperative pain therapy for emergency abdominal surgeries is important far beyond the perioperative period because sensitization to painful stimuli can cause postoperative morbidity. A prospective, double-blind, randomized study was carried out to compare the quality of postoperative analgesia and side-effect profile between epidurally administered butorphanol and nalbuphine as an adjuvant to 0.2% ropivacaine.
