A comparison of the effects of midazolam/fentanyl and midazolam/tramadol for conscious intravenous sedation during third molar extraction.

摘要

PURPOSE: This study evaluated the effects of fentanyl and tramadol, used in combination, as sedation for third molar surgical extraction. PATIENTS AND METHODS: This prospective, randomized, double-blind, placebo-controlled study included 60 patients undergoing extraction of a horizontal third molar with an Amsterdam Preoperative Anxiety and Information Scale score above 10 points. All of the patients were first given a 0.03-mg/kg bolus of midazolam, and then they were randomized into 3 groups: group A, midazolam only; group B, midazolam and 1-mug/kg fentanyl; and group C, midazolam and 1-mg/kg tramadol. The vital signs were recorded. Patients were assessed for postoperative pain and adverse effects, and patient and surgeon satisfaction was assessed. RESULTS: No differences were found in the heart rate among groups (P > .05). The mean blood pressure was also similar until the 40th minute, after which the mean blood pressure in the patients in group A was lower than that in the other 2 groups (P < .01). In the postoperative pain assessment, the visual analog scale scores of the patients in group C were lower than those in the other 2 groups in the first postoperative hour (P < .05). The time at which the first rescue analgesic was taken in groups A, B, and C was 3, 3.5, and 5 hours postoperatively, respectively, and was significantly later in group C (P < .01). No difference was found in patient/surgeon satisfaction among the groups. CONCLUSIONS: Tramadol has a better analgesic effect in third molar surgery than fentanyl and placebo.
