Design outcomes

Primary

MeasureTime frame
To determine the analgesic efficacy of subcostal transversus abdominis plane block in patients undergoing laparoscopic cholecystectomy using visual analog score and numerical pain rating scale To determine the analgesic efficacy of port site infiltration of local anesthetics in patients undergoing laparoscopic cholecystectomy using visual analog score and numerical pain rating scale To compare the postoperative pain scores between the two groups using the Visual Analog Scale (VAS) and numerical pain rating scale (NMS). Timepoint: 30 minutes / 1 hour / 2 hour / 4 hour—

Secondary

MeasureTime frame
1. To evaluate the time to discharge from the recovery unit as an indicator of early postoperative recovery 2. To analyse the requirement of rescue analgesia (TRAMADOL) in the first four hours of the postoperative period in both groups & to compare the analgesic efficacy between themTimepoint: 30 minutes, 1 hour, 2 hours & 4 hours post extubation—
