Effects of preoperative lornoxicam versus tramadol on postoperative pain and adverse effects in adult tonsillectomy patients.

OBJECTIVES: This study assessed the efficacy and adverse effects of preoperatively administered lornoxicam versus tramadol in adults, for post-tonsillectomy pain. METHODS: This prospective, double blind, randomized, clinical research was performed in the Ear, Nose and Throat Surgery Room in the Department of Anesthesia and Reanimation, Gazi University Faculty of Medicine. Forty American Society of Anesthesiologists (ASA) status I-II patients of both gender, aged 18-55 years, were included. RESULTS: Tonsillectomy patients were divided into two groups: Those in Group L received 8 mg lornoxicam and in Group T received 50 mg tramadol intravenously just before induction of general anesthesia. Induction and maintenance of anesthesia (propofol, atracurium, nitrous oxide and sevoflurane) were standardized. Heart rate and systolic and diastolic arterial pressure data were monitored during the anesthesia. Intra-operative bleeding was scored by the same operator using a 5-point scale at the end of the surgery. Postoperative pain on swallowing was scored by a blinded anesthesiologist using Verbal Rating Scale (VRS) on arrival in the Post Anesthesia Care Unit (T(0)), at 30 min (T(1)), 1h (T(2)), 2h (T(3)), 3h (T(4)), 4h (T(5)), 5h (T(6)), and 6h (T(7)) thereafter. During the first postoperative 6 hours, when VRS >/=2, 1mg.kg(-1) im meperidine was used as a rescue analgesic. Adverse effects in the postoperative 6h period were noted. T(1) and T(2) pain scores in Group T were higher than in Group L (p=0.049, p=0.007, respectively). The number of patients requiring rescue analgesics during the first 6 hours in Group L was lower than in Group T. Nausea-vomiting, bleeding and postoperative hemorrhage values were similar between Group L and Group T. CONCLUSION: Preoperative 8 mg lornoxicam was more effective than 50 mg tramadol with respect to early postoperative tonsillectomy pain in adult patients, and side effects were similar.
