Abstract
BACKGROUND: Postoperative pain remains an important challenge after scoliosis surgery in children. Opioids are the mainstay of treatment, and adult studies demonstrate gabapentin as a useful adjunct to opioids in the management of postoperative pain. METHOD: Adolescent patients undergoing idiopathic scoliosis surgery were randomized to receive a single preoperative dose of gabapentin 600 mg or placebo. The primary outcome measure was total morphine consumption in mg·kg(-1) between 0 and 24 h postoperatively. Secondary outcome measures included time to first rescue analgesia, pain intensity scores at rest and with movement, incidence of nausea, vomiting, pruritus, sedation, dizziness, presence of persisting pain symptoms, and patient satisfaction. Cumulative opioid consumption was calculated at each time point: 1, 4, 8, 12, 24, 48, and 72 h. RESULTS: The gabapentin group used 0.087 ± 0.06 mg·kg(-1) of morphine at 1 h, 0.24 ± 0.12 mg·kg(-1) at 4 h, 0.44 ± 0.17 mg·kg(-1) at 8 h, and 1.29 ± 0.44 mg·kg(-1) at 24 h. The placebo group used 0.121 ± 0.06 mg·kg(-1) of morphine at 1 h, 0.35 ± 0.16 mg·kg(-1) at 4 h, 0.56 ± 0.27 mg·kg(-1) at 8 h, and 1.46 ± 0.68 mg·kg(-1) at 24 h. There was no statistically significant reduction in opioid consumption in the patients receiving gabapentin. There were no significant differences in secondary outcomes. CONCLUSION: A single preoperative dose of gabapentin did not show a significant difference in opioid consumption or pain scores in adolescents undergoing idiopathic scoliosis surgery. This study is the first pediatric randomized controlled trial to assess the effectiveness of a single dose of gabapentin on morphine consumption and analgesia following major surgery.

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 it
