Auricular Acupuncture Reduces Intraoperative Fentanyl Requirement During Hip Arthroplasty - A Randomized Double-Blinded Study
Bibliographic record
Abstract
We studied whether auricular acupuncture reduces analgesic requirement during total hip arthroplasty. Sixty-four patients were enrolled in this patient/anesthesiologist-blinded study according to inclusion criteria. They were randomly assigned to receive acupuncture with indwelling fixed needles (points lung, shenmen, forehead and hip) or sham procedure (4 non-acupuncture points on the helix). Surgery was performed under standardized general anesthesia with volatile anesthetic isoflurane and opioid analgesic fentanyl, whereby isoflurane concentration was kept constant. Demographics, fentanyl requirement, duration of general anesthesia and success of patients' blinding were registered. Patients from the acupuncture group required 21% less fentanyl during surgery than those who received sham procedure. Other outcome measures were similar in both groups. Auricular acupuncture reduced fentanyl requirement compared to sham procedure during hip arthroplasty.

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.
