Brief Summary

Plastic and reconstructive surgeons consistently create large, raw surfaces as part of their operative procedures. Thus, plastic \& reconstructive surgery patients are among those at highest risk for anticoagulant-associated bleeding adverse drug events (ADEs). This study seeks to optimize both the safety and effectiveness of post-operative enoxaparin by comparing aFXa levels, bleeding events, and VTE events among plastic \& reconstructive surgery patients randomized to receive two different enoxaparin dose regimens.
