Comparative evaluation of heart rate variability after septoplasty and tonsillectomy

Abstract

The aim of the research was to determine the fluctuations of the autonomic nervous system based on the analysis of changes in certain heart rate variability (HRV) at patients after septoplasty and tonsillectomy. A study of Holter monitoring of 28 patients with nasal septum deviation and of 30 patients with chronic tonsillitis was conducted. Surgical procedures were performed under local infiltration anesthesia with 0,5% novocaine solution. We evaluated standard deviation of RR intervals (SDNN) - 24-hour monitoring, day and night data. After septoplasty for night and day validity period average SDNN did not differ (p < 0,05), but SDNN were significantly different (p < 0,05). Average values for the night and day were different from each other at the patients after tonsillectomy (p < 0,05). SDNN scatter was the same. SDNN in both groups did not differ per day both for average values and for variability (p < 0,05). Septoplasty provokes more pronounced stress response as compared with tonsillectomy. Local anesthesia for septoplasty and tonsillectomy causes a disturbance of adaptive reactions on the part of the autonomic nervous system. HRV analysis can be called an objective and individual method of diagnosis of acute stress conditions in the otorhinolaryngological surgery.
