PurposeWe compared the efficacy of tramadol given before or immediately after surgical extraction of an impacted mandibular third molar under local anesthesia.Materials And MethodsIn this prospective, randomized, controlled, double-blind pilot study, 3 groups of 20 patients each were included: tramadol preoperative, 100 mg intramuscularly (IM) 1 hour before surgery (group A); tramadol postoperative, 100 mg IM immediately after surgery (group B); and saline (group C). We evaluated intensity of pain and analgesic consumption as was requested.ResultsThe analgesic efficacy measured as complete relief of pain at 24 hours was 86% in the preemptive tramadol compared with 70% and 36% for postoperative tramadol administration and control group. A significant reduction in the consumption of analgesics was seen in preoperative group as compared with the postoperative and control groups. Adverse events were minimal and similar in all groups.ConclusionsThis study suggests the preemptive use of tramadol as an alternative for the acute pain treatment after the removal of an impacted mandibular third molar carried out under local anesthesia.
