Peri-Operative Outcomes Comparison of General Anaesthesia and Brachial Plexus Block for Open Reduction Internal Fixation of Metacarpal Fractures
Bibliographic record
Abstract
Introduction: Brachial plexus blockade (BPB) is a procedure of growing popularity amongst surgeons and anaesthesiologists involved with upper limb surgery. The safety and benefit in hand surgery is unclear. Methods: A retrospective chart review was performed examining all operative hand cases over a 2-year period. All cases of metacarpal open reduction internal fixation (ORIF) were included. Cases were excluded if paediatric patient, additional procedures performed, and/or a decreased LOC. Parametric statistical tests were performed. Results: In total, 54 cases with general anaesthesia (GA) and 48 cases with BPB were identified for the study (n = 102). The average total time from operating theatre to discharge was 245 ± 72 minutes in GA group and 195 ± 54 minutes in BPB ( P < .001). Of those who had a GA, 47/54 patients required analgesia post-operatively versus 12/48 in the BPB ( P < .001). Of all, 25/52 and 5/48 patients required anti-emetics post-operatively in the GA and BPB groups, respectively ( P < .001). Need for any parenteral medication post-operatively was also significantly different ( P < .001). Conclusion: This is the first study to specifically examine anaesthetic techniques for ORIF of hand fractures; adding to the body of literature establishing BPB as a safe and efficient method of anaesthesia.

How this classification was reachedexpand
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.
