Abstract
OBJECTIVE: To determine a rational approach to heparin dosing for thromboembolism prophylaxis. DESIGN: Literature review. RESULTS: Three commonly used heparin dosing regimens were identified: (1) standard low-dose heparin (5000 U administered subcutaneously 2-3 times per day); (2) adjusted-dose heparin (adequate to elevate the activated partial thromboplastin time to 5 seconds above the upper limit of normal); and (3) low-molecular-weight heparin (30 mg subcutaneously twice daily without monitoring). CONCLUSIONS: Adjusted-dose heparin thromboembolism prophylaxis is both the safest and most reliable method currently available.
