Abstract
BACKGROUND: Venous thromboembolism (VTE) is a serious and potentially life-threatening surgical complication. However, there is little consensus regarding appropriate VTE prophylaxis for plastic surgery patients. Risk factors as they apply to plastic surgery patients are unclear, and recent recommendations for chemoprophylaxis in these patients may expose them to other additional risks. OBJECTIVES: The authors examine perioperative and intraoperative measures, specifically those that have enabled a large number of patients to undergo outpatient abdominoplasty safely, with a reduced risk of VTE. METHODS: A retrospective review was performed of 404 consecutive abdominoplasty patients who were treated at a single outpatient surgery center between 2000 and 2010. Graded compression stockings and intermittent pneumatic compression devices were placed on all patients, and perioperative and intraoperative warming was strictly applied. Progressive tension suturing technique was performed in all cases and drains were eliminated. All patients received pain pumps, ambulated within one hour of surgery, and were discharged home the same day. Patient VTE risk factors were scored with the Caprini/Davison risk assessment model (RAM). Perioperative and intraoperative measures were taken to reduce factors that may increase VTE risk in abdominoplasty. Complications were recorded, including VTE events, seromas, hematomas, and infections. RESULTS: In this series, 247 abdominoplasty procedures were performed alone and 157 were combined with additional procedures. Under the RAM, 297 patients were considered "high risk" and 17 "highest risk." Abdominoplasty operative time was 100 ± 29 minutes. Only one case of deep vein thrombosis (DVT) occurred, in the calf. CONCLUSIONS: A comprehensive approach to perioperative and intraoperative patient care has allowed outpatient abdominoplasty to be safely performed without VTE chemoprophylaxis in patients with fewer than six risk factors.

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
