Clinical Indicators of Postoperative Bleeding in Bariatric Surgery
Bibliographic record
Abstract
The purpose of this study was to evaluate the relationship between patient, clinical and laboratory characteristics, and bleeding after bariatric surgery. A retrospective chart review was performed for all patients, who underwent a laparoscopic Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy at our institution between March 2012 and May 2014. In total, 788 patients were included in this study. Seventeen patients had postoperative bleeding. The demographics, comorbidities, and preoperative medications were similar between the groups. Mean postoperative hemoglobin in the bleeding group was significantly lower (94 vs. 126; P<0.001) with a larger decrease from the baseline value (-43 vs. -12; P<0.001). The mean heart rate (91 vs. 81; P<0.001) and its increase from baseline (12 vs. -0.01; P<0.001) were significantly different in the bleeding patients. Postoperative hemoglobin and heart rate were associated with bleeding but not systolic blood pressure or patient characteristics. Further research is needed to develop a robust predictive model.

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.
