ABSTRACT
BACKGROUND: Mortality from trauma remains a major public health issue as it is the leading cause of death in persons aged 5 - 44 years. There is a dearth of information on polytrauma from developing countries such as ours. Hence, this topic was studied at our institute. The objective is to study the coagulation parameters in polytrauma patients at our institute and to correlate the findings with the prognosis. METHODS: A prospective study was carried out in the department of pathology in a tertiary care center, during a period of 20 months from December 2012 to July 2014. All the polytrauma patients (injury severity score (ISS) ≥ 15) with injuries to head and neck, face, thorax, abdomen, extremities and external (skin) were included. Sampling was done within 20 min of arrival during primary survey of the patient. Screening tests like bleeding time (BT) and clotting time (CT) were carried out bedside. Other tests carried out were complete blood count (CBC), prothrombin time (PT), activated thromboplastin time (aPTT), thrombin time (TT) and D-dimer assay. Tests were carried out on fresh samples within 2 h of collection. RESULTS: The incidence of coagulopathy was 59.86%. There was significant prolongation of PT, aPTT and TT in those patients who developed coagulopathy. PT was found to be a stronger predictor of mortality among polytrauma patients. CONCLUSION: A significant proportion of polytrauma patients were coagulopathic. Initial coagulation profile is very useful in predicting outcomes for major polytrauma patients. This study emphasizes the importance of early suspicion and basic screening for coagulopathy in polytrauma patients in developing countries.
