Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
A comparative double-blind randomized trial of activated protein C and unfractionated heparin in the treatment of disseminated intravascular coagulation.
A randomized prospective double-blind trial was performed to compare the safety and efficacy of human activated protein C (APC) and unfractionated heparin for the treatment of disseminated intravascular coagulation (DIC). One hundred thirty-two patients with DIC were enrolled in this study: 63 patients received APC (12.5 U [2.5 microg]/kg body wt per hour) and 69 patients received heparin (8 U/kg body wt per hour) by intravenous infusion for 6 days. Forty-nine APC-treated patients and 55 heparin-treated patients were evaluated for efficacy, and 52 APC-treated patients and 55 heparin-treated patients were evaluated for safety. ⋯ The rate of death from any cause within 28 days after treatment was 20.4% in the APC group, significantly lower than the 40% death rate observed in the heparin group (P < .05). There were no severe adverse events in either group. These results suggest that APC in a relatively small dosage can improve DIC more efficiently than can heparin, without increasing bleeding, and may be a better alternative.
