Abstract
PURPOSE: This randomized double-blind study aimed to evaluate the effects of dexmedetomidine on hemodynamic parameters and the quality of surgery and recovery criteria in tympanoplasty operations. MATERIALS AND METHODS: A total of 75 patients 18-55 years undergoing tympanoplasty, who were graded as American Society of Anesthesiologists physical status I-II, were randomly divided into three groups. Group 1 included patients receiving remifentanil alone, Group 2 included patients receiving dexmedetomidine + remifentanil and Group 3 included patients receiving dexmedetomidine + ½ remifentanil. Anesthesia was induced with propofol and cisatracurium. For maintenance of anesthesia, a mixture of 2-2.5% sevoflurane, 40-60% oxygen/air was used. The groups were compared in terms of hemodynamic parameters, surgical area, recovery criteria, modified Aldrete, pain scores, additional analgesic requirements and adverse effects. RESULTS:Mean arterial pressure and heart rate values of Group 1 were higher at the time of intubation, incision, spontaneous breathing and extubation compared to Group 2 and Group 3. Surgical field satisfaction was higher in Group 2 and Group 3 than Group 1. Spontaneous breathing, eye opening and verbal cooperation times were shorter in Group 3 compared to Group 2. Eye opening and verbal cooperation times were longer in Group 2 compared to Group 1. The 30-minute modified Aldrete scores was higher in Group 3 compared to Group 1. There was no difference between the groups in terms of postoperative pain and adverse effects. CONCLUSION: The use of dexmedetomidine during tympanoplasty operations may provide better hemodynamic control and surgical view, may provide faster recovery and may reduce remifentanil consumption.
