Comparison of ultrasound guided Erector Spinae Plane Block and quadratus lumborum block for postoperative analgesia in laparoscopic cholecystectomy patients; a prospective randomized study

Study objectiveErector Spinae Plane Block (ESPB) is a recently described block. Both ESPB and Quadratus Lumborum block type II (QLB-II) have been reported to provide effective postoperative analgesia in patients undergoing laparoscopic cholecystectomy (LC). In this study, we compared the postoperative analgesic effects of ESPB and QLB-II in patients undergoing LC.DesignAssessor Blinded, prospective, randomized, controlled study.SettingTertiary hospital, postoperative recovery room & ward.Patients80 patients (ASA I-II) were recruited. Patients were allocated in to two equal groups (ESB and QLB-II). All patients were included in analysis.InterventionsStandard multimodal analgesia was performed in all groups. ESPB and QLB-II were performed under ultrasound guidance.MeasurementsMean opioid consumptions and Numeric Rating Scores was measured during the first 24 postoperative hours.Main resultsDemographic data was similar between groups. There was no difference between NRS scores and opioid consumption at any hour between the groups.ConclusionWhile ESPB and QLB-II are not significantly different, they improve analgesia quality in patients undergoing LC.
