Design outcomes

Primary

MeasureTime frame
Establish the correlation between pupillary diameter and quantium nociception index (qNOX) values for estimation of intraoperative pain during general anaesthesia in laparoscopic cholecystectomyTimepoint: T0(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
Correlation between pupillary diameter and hemodynamic parameters (HR, SBP, DBP, MAP) at different time intervals.Timepoint: T0(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
