Background and Aim: Narcotics have been used since long as a component of balanced anaesthesia, thus minimizing the anaesthetic requirement both during induction and maintenance as well as attenuating the pressor response during laryngoscopy and intubation. Equally significant is their role in provision of smoother recovery period by minimizing postoperative pain. Other than pain, the factors like postoperative nausea and vomiting (PONV), shivering, sedation and respiratory depression are equally important in recovery from the effects of anaesthetic drugs. The present study aimed at comparing the postoperative recovery characterstics of fentanyl and butorphanol in patients undergoing open cholecystectomy under general anaesthesia. Materials and Methods : The present study configured one hundred adults patients of American Society of Anaesthesiologists (ASA) grade 1 or 2 of either sex scheduled to undergo elective open cholecystectomy and were randomly assigned to receive fentanyl (group F; n = 50) or butorphanol (group B; n = 50). Both group were premedicated with midazolam 0.04 mg/kg intravenously followed by injection fentanyl 2 mcg/kg or butorphanol 40 mcg/kg. Standard induction was done with propofol 2 mg/kg and vecuronium 0.1 mg/kg was used for intubation. Anaesthesia was maintained with propofol infusion and 67% nitrous oxide in oxygen. Intraoperative hemodynamic parameters were observed and recorded. Postoperatively analgesia, sedation, PONV, shivering, respiratory depression and recovery score were observed. Results: The recovery time was less in group F ( P > 0.05) while post operative analgesia ( P < 0.001) and sedation ( P > 0.05) was more in group B. The incidence of respiratory depression was more in group B ( P > 0.05). PONV was comparable in both the groups. Postoperative shivering was significantly low in group B ( P < 0.05). Conclusion: It is concluded that besides easy availability and lower cost, butorphanol decreased propofol consumption intraoperatively and provided better analgesia and prophylaxis against shivering in postoperative period.
