Comparison of ultrasound-guided transversus abdominis plane block and caudal epidural block for postoperative analgesia in paediatric lower abdominal surgeries: A randomised controlled trial
Bibliographic record
Abstract
ABSTRACT Background and Aims: Ultrasound-guided transversus abdominis plane (TAP) block is an effective technique for postoperative analgesia in lower abdominal surgeries. This study aims to compare the duration and efficacy of an ultrasound-guided TAP block with those of a caudal epidural for paediatric unilateral lower abdominal surgeries. Methods: After ethical approval, sixty children aged 1 to 9 years were randomised into ultrasound-guided TAP block or caudal block with general anaesthesia for unilateral lower abdominal surgeries. The primary endpoint was time for the first rescue analgesia in the postoperative period. The secondary endpoints were total postoperative opioid consumption, modified Children Hospital of Eastern Ontario Pain Scale (CHEOPS) and the Face, Legs, Activity, Cry and Consolability (FLACC) scale in the postoperative period. Results: The mean time for first rescue analgesia was 11.33 ± 2.80 h in the TAP block group, while in the caudal group, it was 13.18 ± 2.67 h (95% confidence interval [CI] mean difference 2.58–10.58, P = 0.017). The total postoperative morphine requirement was comparable in both groups at both 12 h (TAP block group 0.50 ± 0.12 mg vs. caudal block group 0.56 ± 0.12 mg, 95% CI mean difference 0.09–0.02, P = 0.08) and 24 h (TAP block group 0.96 ± 0.30 mg vs. caudal block group 0.81 ± 0.34 mg, 95% CI mean difference 0.06–0.32, P = 0.06) time period. Conclusion: The mean time for first rescue analgesia was lesser in the TAP block group as compared to caudal group.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
