Design outcomes

Primary

MeasureTime frame
Pupillary diameter (PD) in patients undergoing propofol and sevoflurane anesthesia at the time of incision at comparable depths of sedation and nociception.Timepoint: TO (Baseline) - before induction T1 - 1 min after induction T2 - At skin incision T3 - During trochar insertion every 15 min interval following T3 At the end of surgery

Secondary

MeasureTime frame
Pupillary diameter at other predefined time intervals Timepoint: TO (Baseline) - before induction T1 - 1 min after induction T2 - At skin incision T3 - During trochar insertion every 15 min interval following T3 At the end of surgery;Change in pupillary diameters from baseline diameters at various predefined time intervals during the procedureTimepoint: TO (Baseline) - before induction T1 - 1 min after induction T2 - At skin incision T3 - During trochar insertion every 15 min interval following T3 At the end of surgery
