Name of journal: American journal of surgeryAbstract: BACKGROUND: We evaluated the association between operating room time and developing a deep vein thrombosis (DVT) or pulmonary embolus (PE) after emergency general surgery (EGS).CONCLUSION: Prolonged operating room time is independently associated with increased risk of developing VTE complications after an EGS procedure. Most of the VTE complications were delayed in presentation.Copyright (c) 2019. Published by Elsevier Inc.METHODS: We reviewed six common EGS procedures in the 2013-2015 NSQIP dataset. After tabulating their incidence of postoperative VTE events, we calculated predictors of developing a VTE using adjusted multivariate logistic regressions.RESULTS: Of 108,954 EGS patients, 1,366 patients (1.3%) developed a VTE postoperatively. The median time to diagnosis was 9 days [5-16] for DVTs and 8 days [5-16] for PEs. Operating room time of 100min or more was associated with increased risk of developing a DVT (OR 1.30 [1.12-2.21]) and PE (OR:1.25 [1.11-2.43]) with a 7% and 5% respective increase for every 10min increase after the 100min. Other independent predictors of VTE complications were older age, and history of cancer, and emergent colectomies on procedure-level analysis.All authors: Choron RL, Ezzeddine H, Hamidi M, Haut ER, Joseph BA, Lunardi N, Mehta A, Reid J, Sakran JV, Zeeshan MFiscal year: FY2019Digital Object Identifier: Date added to catalog: 2019-06-21
