Oral naproxen versus oral tramadol for analgesia after cesarean delivery

ObjectiveTo compare the efficacies of oral naproxen and oral tramadol for pain relief after cesarean delivery, and to evaluate administration at fixed intervals versus on request.MethodsIn a prospective study, 120 women were randomized into 4 groups receiving either oral naproxen or oral tramadol at fixed intervals or on request. Pain was assessed at 6, 12, 24, and 48 hours after delivery, and adverse effects, mobility, breastfeeding, and the need for additional drugs for breakthrough pain were recorded.ResultsNo difference in pain scores was observed at 6, 12, 24, or 48 hours among the 4 groups, between the 2 drugs, or between the 2 methods of administration. Women randomized to receive oral tramadol requested additional drugs for breakthrough pain more frequently. In addition, adverse effects were twice as common in the tramadol group as in the naproxen group, and more women in the tramadol group abandoned the study.ConclusionAlthough similar in terms of pain scores, oral naproxen might be more effective than oral tramadol for pain relief after cesarean delivery. Naproxen seemed to have a better adverse-effects profile, and therefore might be more suitable for mothers. Administration at fixed intervals might be more efficacious than administration on request.
