of one year from January to December2011 for this study. The basic predictors in this study included age, sex, rural/
urban, mechanism of injury, with injury to other organs, Glasgow Coma Scale, pupil size and reactivity, radiological
findings, treatment given in hospital and referral to other hospitals.
Results: Majority of patients belonged to age group ofup to 10 years (27.5%) and maximum deaths (30) were seen in
age group 31 to 40 years. Maximum number of patients were males 264 (75.9%) and 281 (71.1%) Traumatic brain Injury
patients were from rural areas. All the patients were having GCS 4±2 (3-8) and 180 (45.56%) patients were having equal
