Stress response and state of cognitive functions in the perioperative period in elderly patients during laparoscopic cholecystectomy

Abstract
The aim. To investigate the dynamics of stress markers and the state of cognitive functions in the perioperative period during laparoscopic cholecystectomy in elderly patients. Materials and methods. We examined 84 patients aged 68.1 ± 0.6 years, with diagnosed gallstone disease, acute cholecystitis, who underwent laparoscopic cholecystectomy. Patients were randomized into 2 groups: Group I - inhalation anesthesia based on sevoflurane with mechanical ventilation; Group II - TBA based on propofol with mechanical ventilation. Hemodynamic parameters, dynamics of stress markers (cortisol, insulin, glucose) and cognitive function were investigated. Results. Glucose and insulin levels in both groups remained within normal limits at all stages of the study. The baseline cortisol level was higher than normal in both groups, but at 4, 5, 6 stages of the study decreased significantly compared with baseline values (p
