This was a double-blinded, prospective randomized controlled trial to compare the postoperative analgesia, side effects profile and overall satisfaction in patients who received intrathecal fentanyl with or without morphine for elective Caesarean. Sixty ASA I and II parturients were randomized into two groups. Group I received intrathecal fentanyl with 0.1 mg morphine and Group II received intrathecal fentanyl only. Postoperatively, all patients were provided with oral analgesics. The degree of post-operative pain score was assessed by verbal pain score. The incidence of side effects was assessed every 4 hours for 24 hours, which included incidence of nausea, vomiting, pruritus, sedation and evidence of respiratory depression. Patient's overall satisfaction was also recorded. The verbal pain score was significantly lower in morphine group up to 20 hours postoperative period. The incidence of pruritus, nausea and vomiting were statistically significant up to 12 hours postoperative. There was no incidence of severe side effects in all the patients. There was significant difference between the morphine and no morphine group in terms of overall patient satisfaction. There was significant difference in terms of lower pain score, higher incidence of side effects with better patients' overall satisfaction in morphine group.
