AbstractThis article details a double-blind, randomized, placebo-controlled pilot study evaluating the analgesic efficacy and clinical acceptability of intravenous tramadol in patients undergoing surgical removal of an impacted third molar tooth under local anesthesia and intravenous sedation with propofol. Forty-five ASA status 1 dental outpatients were randomly allocated to 2 groups of 22 (group A) and 23 (group B) patients each (n = 45). Group A (T/P) received intravenous tramadol 1.5 mg/kg injected over 2 minutes, followed by a bolus dose of intravenous propofol 0.4 mg/ kg. Maintenance consisted of a continuous infusion of propofol 3 mg/kg/h, with an additional bolus dose of 0.4 mg/kg intravenously 2-3 minutes prior to the infiltration of the local anesthetic solution. Group B (P/P) patients received no tramadol but instead a saline placebo solution and an identical amount of propofol. Overall, in this study, postoperative pain was much better controlled in the group receiving tramadol 1.5 mg/kg intravenously despite there being no significant difference in the dose of propofol administered in both groups. Intravenous tramadol, when given with propofol, did not affect the cardiovascular, respiratory, and sedative effects of propofol. Following tramadol, despite being an opioid, no nausea and vomiting were reported in the early postoperative period, indicating the value of using tramadol with propofol. Thus, this pilot study demonstrated the potential use of intravenous tramadol with propofol in day-case dento-alveolar surgery.
