Design outcomes

Primary

MeasureTime frame
Postoperative pain intensity assessed using the Visual Analog Scale (VAS) at predetermined time intervals (0, 2, 4, 6, 8, 12, 16, 20, and 24 hours postoperatively).Timepoint: From immediate postoperative period (0 hour) up to 24 hours postoperatively at predetermined time intervals (0, 2, 4, 6, 8, 12, 16, 20, and 24 hours postoperatively).—

Secondary

MeasureTime frame
1)Time to first rescue analgesic requirement after surgery (in hours). 2)Total postoperative tramadol requirement within 24 hours. 3)Total intraoperative fentanyl requirement (in micrograms). 4)Hemodynamic response to pneumoperitoneum Heart Rate (HR), Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP), and Mean Arterial Pressure (MAP) recorded every 15 minutes intraoperatively. 5)Total procedure time (sum of ultrasound scanning and needling time in minutes).Timepoint: Intraoperative and up to 24 hours postoperatively.—
