BACKGROUND AND OBJECTIVES: Low spinal morphine doses are effective in relieving postoperative pain of patients submitted to Cesarean sections, with low incidence of side-effects. This study aimed at evaluating postoperative analgesia and the incidence of side-effects in patients submitted to Cesarean sections under spinal anesthesia with hyperbaric bupivacaine and 0.05 mg and 0.1 mg morphine associated to intravenous and oral ketoprofen. METHODS: Sixty pregnant women, physical status ASA I and II, undergoing elective Cesarean sections, were divided in two groups: group 1 patients were given 0.1 mg spinal morphine, while group 2 received 0.05 mg morphine, both associated to 15 mg hyperbaric bupivacaine. All patients received perioperative 100 mg intravenous ketoprofen and oral ketoprofen at 8-hour intervals in the first postoperative day. Patients were assessed at 6, 12 and 24 hours after surgery for pain intensity and side-effects (sedation, pruritus, nausea and vomiting). Side-effects were also evaluated in the perioperative period. RESULTS: Both groups were similar in demographics and surgery and anesthesia duration. They were also homogeneous in postoperative pain intensity and presence of pruritus, sedation, nausea and vomiting. CONCLUSIONS: Spinal 0.05 mg and 0.1 mg morphine associated to intravenous and oral ketoprofen have provided the same postoperative analgesia and have determined the same incidence of side-effects.
