autonomic nervous system analysis
electrocardiographic and pulse-photoplethysmographic waves of patients under general anesthesia for laparoscopic cholecystectomy will be recorded on a laptop pc for offline analysis of autonomic nervous system modulation a three main time point: 1) at baseline, before general anesthesia induction, 2) five min after tracheal tube placement, 3) five min after pneumoperitoneum insufflation.
