Partial Thromboplastin Time After 72 Hours of Antithrombotic Prophylaxis Using Unfractionated Heparin

Summary

This study is designed to assess: the incidence of abnormal partial thromboplastin time in patients receiving unfractionated heparin (UFH) 5000 U 2 times a day versus 3 times a day 72 hours after administration of the first dose of heparin. Hypothesis: The basic hypothesis of this study is that patients receiving UFH 5000 U subcutaneously 3 times a day will have a higher proportion of elevated partial thromboplastin time than patients receiving UFH 5000 U subcutaneously twice a day.
