Minimization of Bleeding Related Adverse Drug Events in Plastic & Reconstructive Surgery Patients Randomized to Different Postoperative Anticoagulant Regimens

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.

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). Our
preliminary data has shown that a fixed, or "one size fits all" dose of enoxaparin, an
anticoagulant, can allow a high proportion of patients to have appropriately thinned blood,
measured by anti-Factor Xa (aFXa) levels. Patients with adequate aFXa levels are known to
have significantly decreased venous thromboembolism risk (VTE), which is desirable. However,
30% of patients who receive fixed dose enoxaparin have blood that is too thin. Patients who
are over-anticoagulated are significantly more likely to have ADEs including bleeding
requiring return to the operating room, need for blood transfusion, or death. The optimal way
to dose enoxaparin to minimize ADEs remains unknown. 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.
