Evaluation of heparin prophylaxis protocol on deep venous thrombosis and pulmonary embolism in traumatic brain injury

Abstract

There is currently no accepted standard for deep venous thrombosis (DVT) and pulmonary embolism (PE) prophylaxis in patients with traumatic brain injury (TBI). The objective of our study was to evaluate the effects of implementing a subcutaneous heparin prophylaxis protocol for patients with TBI that began in our hospital as of June 2009. In our retrospective cohort study, we examined 3812 TBI records between January 2007 and December 2011. A significant reduction in the risk of DVT/PE development was not demonstrated by comparing DVTand PE incidences before and after protocol implementation. A clear trend between heparin use and DVToccurrence could not be determined from a review of TBI records after June 2009. The use of heparin after initiation of our protocol among operative TBI cases without intracranial hemorrhage (ICH) based on admission head computed tomography was 58 per cent. ICH complication from heparin prophylaxis was 10.6 per cent for patients with TBI with ICH on admission (five of 47 cases) compared with 0.7 per cent for those without ICH on admission (four of 535 cases). © Southeastern Surgical Congress.
