Overview

Brief Summary

Study Title: Comparative evaluation of analgesic efficacy of ultrasound guided external oblique intercostal plane block versus port site infiltration in patients undergoing laparoscopic cholecystectomy under general anaesthesia. Study Type: Interventional, Randomized, Double-Blind, Parallel comparative study

Objective:  To compare the analgesic efficacy of ultrasound guided unilateral external oblique intercostal plane block versus local port site infiltration in patients undergoing laparoscopic cholecystectomy under general anaesthesia.

Participants: Adult patients aged 18–65 years, ASA physical status I–II, body mass index 18 - 30 kg/m² scheduled for elective laparoscopic cholecystectomy under general anaesthesia.

Interventions:

  • Group A: Patients will receive right sidedultrasound- guided external oblique intercostal plane block using 20 ml of 0.20% ropivacaine after induction of anaesthesia
  • Group B: Patients will receive local infiltration at port site using 20 ml of 0.20% ropivacaine after induction of anaesthesia.

Primary Outcome: To evaluate and compare time to first rescue analgesia postoperatively

Secondary Outcomes:

  • Hemodynamic parameters intraoperatively at  5, 30, 60, 90 minutes, at the end of surgery and postoperatively at 1, 6, 24 hours
  • Intraoperative fentanyl (microgram) requirement
  • Postoperative Numerical Rating Scale (NRS) score for pain at rest, deep breathing at 1, 6, 24 hours and on movement at 24 hours
  • Total rescue analgesic requirement in first 24 hours
  • Patient’s satisfaction score at 6 hours postoperatively
  • Incidence of postoperative nausea and vomiting (PONV) in first 24 hours

Sample Size:  50 patients (25 per group) .

**Rationale:**EOIPB is a newer interfascial analgesic technique that anaesthetise lateral as well as anterior cutaneous branches of T6–T10 intercostal nerves and provides better outcomes in reducing postoperative pain and opioid consumption in post laparoscopic cholecystectomy patients.
