Patient-Reported Quality of Recovery after Local Anesthesia versus Brachial Plexus Block in Hand Surgery: A Randomized Controlled Study
Bibliographic record
Abstract
BACKGROUND: Both local anesthesia (LA) and brachial plexus (BP) anesthesia are commonly used in hand surgery. LA has increased efficiency and reduced costs, but BP is often favored for more complex hand surgery, despite requiring greater time and resources. The primary objective of this study was to assess the quality of recovery of patients who received LA or BP block for hand surgery. Secondary objectives were to compare postoperative pain and opioid use. METHODS: This randomized, controlled, noninferiority study enrolled patients undergoing surgery distal to the carpal bones. Patients were randomized to either LA (wrist or digital block) or BP block (infraclavicular block) before surgery. Patients completed the Quality of Recovery-15 questionnaire on postoperative day (POD) 1. Pain level was assessed with a numeric pain rating scale, and narcotic consumption was recorded on POD1 and POD3. RESULTS: A total of 76 patients completed the study (LA, n = 46, BP, n = 30). No statistically significant difference was found for median Quality of Recovery-15 score between LA [127.5 (interquartile range, 28)] and BP block [123.5 (interquartile range, 31)]. The inferiority margin of LA to BP block at the 95% confidence interval was less than the minimal clinically important difference of 8, demonstrating noninferiority of LA compared with BP block. There was no statistically significant difference between LA and BP block for numeric pain rating scale scores or narcotic consumption on POD1 and POD3 ( P > 0.05). CONCLUSION: LA is noninferior to BP block for hand surgery with regard to patient-reported quality of recovery, postoperative pain, and narcotic use. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.

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.
