Subcutaneous enoxaparin for outpatient anticoagulation therapy in a patient with an aortic valve replacement

Pharmacotherapy
H J ManleyR E Garris

Abstract

Low-molecular-weight heparins have been administered for a variety of clinical conditions. A patient with a mechanical aortic valve replacement patient underwent elective transurethral prostatectomy. Anticoagulation was managed with unfractionated heparin immediately preoperatively and postoperatively. Warfarin was begun on postoperative day 1. The patient had a prolonged hospitalization due to subtherapeutic international normalized ratios (INR) despite warfarin administration. Because he intended to leave the hospital against medical advice before therapeutic INR was achieved, enoxaparin 1 mg/kg subcutaneously every 12 hours was prescribed to provide anticoagulation, facilitating discharge and improving the patient's quality of life. Enoxaparin was associated with an approximate saving of $4500 over warfarin. The only adverse event reported was bruising at the injection site.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
