Oblique subcostal transversus abdominis plane block versus transmuscular quadratus lumborum block for postoperative analgesia and quality of recovery in laparoscopic gynecological surgery: a prospective randomized controlled double-blind trial
Abstract
BACKGROUND: During laparoscopic gynecological surgeries, trocar incisions, pneumoperitoneum and distention of the anterior abdominal wall can cause postoperative pain. Inadequate pain management can increase the risk of postoperative complications. The present study compared the effects of oblique subcostal transversus abdominis plane (OSTAP) block and transmuscular quadratus lumborum (TQL) block on postoperative analgesia and quality of recovery (QoR) in patients undergoing laparoscopic gynecological surgery. METHODS: A total of 73 patients were enrolled in this prospective, randomized, controlled, double-blind study. The patients were randomly allocated to the OSTAP group (n = 36) or the TQL group (n = 37). General anesthesia was induced following bilateral block administration with 20 ml of 0.25% bupivacaine. The primary outcome was postoperative tramadol requirement. Secondary outcomes included postoperative paracetamol requirement, time to first paracetamol and tramadol requirement, total paracetamol and tramadol consumption, visual analog scale (VAS) scores at rest and during movement, and Quality of Recovery-15 (QoR-15) scores preoperatively and 24 h postoperatively. RESULTS: Postoperative tramadol requirement was significantly lower in the TQL group (p = 0.006). Total paracetamol consumption was also significantly lower in the TQL group (p = 0.002). No significant between-group difference was observed in VAS scores at rest, whereas VAS scores during movement were…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 73 participants or records.
