Evaluation of ultrasound-guided erector spinae plane block for postoperative analgesia in laparoscopic cholecystectomy: A prospective, randomized, controlled clinical trial

Abstract

Study objective: Laparoscopic cholecystectomy (LC) is a commonly performed minimally invasive procedure that has led to a decrease in procedure-related mortality and morbidity. However, LC requires analgesia that blocks both visceral and somatic nerve fibers. In this study, we evaluated the effectiveness of Erector Spinae Plane Block (ESPB) for postoperative analgesia management in LC.

Design: Single-blinded, prospective, randomized, efficiency study.

Setting: Tertiary university hospital, postoperative recovery room & ward.

Patients: 36 patients (ASA I-II) were recruited in two equal groups (block and control group). Following exclusion, 30 patients were included in final analysis.

Interventions: Standard multimodal analgesia was performed in Group C (control) while ESPB block was also performed in Group B (block).

Measurements: Pain intensity between groups were compared using Numeric Rating Scores (NRS). Also, tramadol consumption and additional rescue analgesic requirement were measured.

Main results: NRS was lower in Group B during the first 3 h. There was no difference in NRS scores at other hours. Tramadol consumption was lower in Group B during the first 12 h. Less rescue analgesia was required in Group.

Conclusion: Bilateral ultrasound guided ESPB leads to effective analgesia and a decrease in analgesia requirement in first 12 h in patients undergoing LC.
