dc.description.abstractBACKGROUND: Bleeding during rhinoplasty leads to many undesirable effects, such as loss of vision in the surgery area, complications during the procedure, and postoperative complications. The most important effect that increases bleeding is hemodynamic changes during surgery. Considering that osteotomy is the most challenging process in rhinoplasty, this study aimed to examine the hemodynamic changes during osteotomy and changes in the depth of anesthesia. METHODS: A total of 50 patients, aged 18 to 65 years with an ASA (American Society of Anesthesiology) score of 1 and 2, who underwent osteotomy during rhinoplasty under general anesthesia, were examined retrospectively. After routine monitoring, the patients underwent general anesthesia induction and endotracheal intubation. Before the surgery, they received remifentanil 1??g/kg as an intravenous bolus followed by 0.5??g/(kg·min) as intravenous infusion until the end of the surgery. The hemodynamic parameters and depth of anesthesia [bispectral index (BIS) values] of the patients were examined before anesthesia, 10?minutes before osteotomy, during osteotomy, and 10?minutes after osteotomy. RESULTS: A significant difference was found in heart rate (beats/min), systolic and diastolic blood pressures (mm Hg), and BIS values of the patients measured before, during, and after osteotomy (P < 0.001). The heart rate, systolic and diastolic blood pressures, and BIS values were significantly higher during osteotomy. Until the 10th minute after osteotomy, all 4 parameters nearly reached the values measured before osteotomy. CONCLUSIONS: Osteotomy directly affects hemodynamic parameters and depth of anesthesia. Hence, it is of utmost importance that the analgesic need and depth of anesthesia are adequately monitored and adjusted during osteotomy. By suppressing hemodynamic stress responses, the amount of bleeding can be reduced, thus increasing the surgical success and the patient's comfort.en_US
