Analgesic efficacy of ultrasound guided quadratus lumborum block versus ilioinguinal/iliohypogastric nerve block following pediatric open inguinal hernia repair: A prospective randomized controlled trial
Bibliographic record
Abstract
Background and Aims: Inguinal hernia repair is a common surgical procedure. We compared the analgesic efficacy of ultrasound-guided anterior quadratus lumborum (QL) block versus ilioinguinal/iliohypogastric (II/IH) nerve block in pediatric patients undergoing open inguinal hernia repair. Material and Methods: It was a prospective randomized study in which 90 patients of 1-8 years of age were randomly assigned into control (general anesthesia only), QL block, and II/IH nerve block groups. Children's Hospital Eastern Ontario Pain Scale (CHEOPS), perioperative analgesic consumptions, and time to first analgesic request were recorded. The normally distributed quantitative parameters were analyzed by one-way ANOVA with post-hoc Tukey's HSD test while parameters that did not follow a normal distribution and the CHEOPS score were analyzed using the Kruskal-Wallis test followed by the Mann-Whitney U test with Bonferonni correction for post-hoc analysis. Results: = 0.000) while comparable between the latter two groups. CHEOPS scores were significantly lower in the QL block group than the control group and II/IH nerve block group at 12 and 18h. The intraoperative fentanyl and postoperative paracetamol consumptions in the control group were higher than II/IH and QL groups while lower in QL than II/IH group. Conclusion: Ultrasound-guided QL and II/IH nerve blocks provided effective postoperative analgesia in pediatric patients undergoing inguinal hernia repair with lower pain scores and less perioperative analgesic consumptions in the QL block group compared to II/IH group.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
