Additional Information

Official title Randomized-Double Blind Trial to Assess the Incidence and Clinical Relevance of Heparin-Induced Thrombocytopenia (HIT) Antibodies in Trauma Patients Treated With Unfractionated or Low-Molecular Weight Heparin, the HIT-TRAP Trial
Principal investigator Andreas Greinacher, Prof. Dr.
Description This is a randomised, double blind trial including trauma patients with need for thrombosis prophylaxis with heparin. Patients receive either unfractionated heparin (UFH) or low-molecular-weight heparin (LMWH). Heparin-induced thrombocytopenia (HIT) antibodies are measured on days 1 and 10. There are daily platelet counts. On discharge an ultrasound doppler of the lower extremities is performed to rule out deep vein thrombosis (DVT). Three months after discharge every patient is answering a questionnaire about thromboembolic complications following discharge. The key questions of the study are whether the two heparins cause HIT-antibodies in differing frequencies, and if yes, whether these differences lead to different clinical outcomes.
