Of 400 patients mortality was observed in 50 patients (12.7%) of which majority were males (54%). Of the non-survivors, 27.3% had prior history of cerebrovascular accident. Difference was noted in clinical presentation among non-survivors with unconsciousness (14%) and gasping (12%). Differences were noted in median of platelets [251(190-331) versus 183.5(155-228.5)] and Creatinine [1.1(0.9-1.7) versus 2.1(1.4-2.4)] between survivors and non-survivors. Majority of non-survivors had deranged coagulation profile and hypoxaemia.
