Abstract
Purpose: To assess the clinical efficacy of midazolam plus low-dose ketamine conscious intravenous sedation on relief from or prevention of postoperative pain, swelling, and trismus after the surgical extraction of third molars. Patients and Methods: Patients admitted for surgical extraction of mandibular third molars (n = 50) were included. All patients received an initial dose of 0.03 mg/kg intravenous midazolam; then patients in the midazolam-placebo (MP) group received 2 mL of a placebo IV, while patients in the midazolam-ketamine (MK) group received 2 mL of a ketamine + saline combination (0.3 mg/kg ketamine + saline) IV. Results: Facial swelling on postoperative days was significantly lower in the MK group than in the MP group (P = .001). Mouth opening on postoperative days was significantly greater in the MK group than in the MP group (P = .001). Pain scores measured on a visual analog scale at 4, 12, and 24 hours after surgery were significantly higher in the MP group than in the MK group (P = .001). Conclusions: Conscious intravenous sedation with midazolam/low-dose ketamine during surgical extraction of third molars can provide the patient with a comfortable procedure and good postoperative analgesia, with less swelling and significantly less trismus. Intravenous low-dose ketamine may be safe and effective in reducing postoperative pain. (C) 2011 American Association of Oral and Maxillofacial Surgeons J Oral Maxillofac Surg 69:1023-1030, 2011
