The analgesic efficacy of tramadol versus ketorolac in day-case laparoscopic sterilisation

Abstract

We conducted a prospective, randomised, double-blind study to compare the analgesic efficacy of intravenous tramadol 1.5 mg.kg-1 and ketorolac 10 mg in 60 ASA grade 1 and 2 patients scheduled to undergo day-case laparoscopic sterilisation by application of Filshie clips. Patients who received tramadol had significantly less postoperative pain in the recovery room (p = 0.007) and at discharge from the day-surgery unit (p = 0.03), and they required rescue analgesia with morphine less often (p = 0.02) than patients who received ketorolac. No difference in either the incidence or severity of nausea and vomiting was observed between the two groups. Both analgesic drugs were well tolerated at the doses given in the study, although dry mouth was significantly more common after the administration of tramadol (p = 0.009). Three patients in the tramadol group and five in the ketorolac group required overnight admission due to pain or nausea and vomiting.
