Analgesic efficacy of ilioinguinal/iliohypogastric, transversus abdominis plane, and quadratus lumborum blocks in inguinal hernia surgery: A prospective randomized controlled trial
Abstract
ObjectiveThis study compared the efficacy of ilioinguinal/iliohypogastric, transversus abdominis plane, and quadratus lumborum blocks as adjuncts to spinal anesthesia for postoperative pain management in unilateral inguinal hernia repair.MethodsThis study was a prospective, randomized, controlled, single-blind study. Eighty patients were randomized into four groups: (a) ilioinguinal/iliohypogastric block group; (b) transversus abdominis plane block group; (c) quadratus lumborum block; and (d) control group. Postoperative pain was assessed using the visual analog scale at rest and during movement over 24 h. Total tramadol consumption via patient-controlled analgesia, supplemental paracetamol use, and opioid-related adverse effects were recorded.ResultsNo statistically significant differences were found in visual analog scale scores among the groups at any time point (p > 0.05). Opioid consumption ranged from 60 to 300 mg, with a mean value of 226.79 ± 49.94 mg. There was no statistically significant difference in opioid use among the groups (p = 0.930; p > 0.05). The requirement for additional analgesics did not differ significantly among the groups (p = 0.389; p > 0.05). The overall incidence of adverse effects (postoperative nausea and vomiting, and respiratory depression) was 11.2% (n = 9). No statistically significant differences were observed in the rate of adverse effects between the groups (p = 0.069; p > 0.05).ConclusionNo statistically significant differences were…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 9 participants or records.
