Abstract
PURPOSE: To compare the autonomic reflexes caused by inferior turbinate outfracture or bipolar cauterization for inferior turbinate reduction surgery. METHODS: The investigators designed and implemented a prospective study composed of 80 patients who underwent a septoplasty with inferior turbinate reduction. The predictor variable was the type of bilateral reduction operation and included inferior turbinate outfracture with a freer elevator and 20 watts bipolar cauterization for 15 s per side after septoplasty. The primary outcome variable was the intraoperative changes of the heart rate monitored preoperatively and 20 s, 1 min, and 4 min after the turbinate reduction procedure. Other variables were systolic and diastolic blood pressure alterations after the inferior turbinate outfracture or bipolar cauterization procedure. Descriptive and bivariate statistics were computed and the P-value was set at .05. RESULTS: The sample was composed of 160 procedures in 80 patients grouped as follows: Outfracture (n = 100) and Cauterization (n = 60). There were no significant differences between the ages; grades of the turbinate hypertrophy; preoperative heart rates; and intraoperative 4th-minute heart rates, systolic and diastolic blood pressures. However, baseline systolic (p < 0.001) and diastolic (p < 0.001) blood pressures of the bipolar cauterization group were higher than outfracture group. Bipolar cauterization did not cause any significant changes in the heart rate, systolic and diastolic blood pressures. Inferior turbinate outfracture procedure caused a significant increase in heart rate (65.4 ± 9.82, p < 0.001), systolic (103 ± 8.62, p < 0.001) and diastolic (63.5 ± 7.37, p < 0.001) blood pressures. CONCLUSION: The results of this study suggest that during the inferior turbinate outfracture procedure, it is important to closely monitor sympathetic and parasympathetic reflexes. The surgeon, and anesthesiologist, must be aware of the early stages of the autonomic reflexes during turbinate reduction.
