Background The aim of this study was to compare the safety of early (≥48 hours), intermediate (48 to 72 hours), and late (≥72 hours) venous thromboembolism prophylaxis in patients with blunt abdominal solid organ injury managed nonoperatively.
Methods We performed a 6-year (2006 to 2011) retrospective review of all trauma patients with blunt abdominal solid organ injuries. Patients were matched using propensity score matching in a 2:1:1 (early:intermediate:late) for age, gender, systolic blood pressure, Glasgow Coma Scale, Injury Severity Score, and type and grade of organs injured. Our primary outcome measures were: hemorrhage complications and need for intervention (operative intervention and/or angioembolization).
Results A total of 116 patients (58 early, 29 intermediate, and 29 late) were included. There were no differences in age (P =.5), Injury Severity Score (P =.6), type (P =.1), and grade of injury of the organ (P =.6) between the 3 groups. There were 67 liver (43.2%), 63 spleen (40.6%), 49 kidney (31.6%), and 24 multiple solid organ (15.4%) injuries. There was no difference in operative intervention (P =.8) and postprophylaxis blood transfusion (P =.3) between the 3 groups.
Conclusions Early enoxaparin-based anticoagulation may be a safe option in trauma patients with blunt solid organ injury. This study showed no significant correlation between early anticoagulation and development of bleeding complications.
