Comparison of Two Methods of Antepartum Anticoagulation: Continuation of Enoxaparin until Scheduled Induction of Labor Versus Transitioning to Heparin with Spontaneous Labor.

Pregnancy is a hypercoagulable state. There is a lack of strong evidence-based guidance regarding management when anticoagulation is required to prevent or treat venous thromboembolism during pregnancy. In practice, some patients are prescribed enoxaparin and transitioned to heparin due to the shorter half-life in the setting of an unpredictable delivery despite less predictable pharmacokinetics of heparin compared with enoxaparin, while others are continued on enoxaparin with a scheduled delivery.
