Predictors of mortality in severely head-injured patients with civilian gunshot wounds: A report from the nih traumatic coma data bank

Predictors of outcome were examined in this prospective study of 151 patients severely injured by civilian gunshot wounds. Of the 151 patients, 133 (88%) died. Of the 123 patients with an initial Glasgow Coma Scale score of 3–5, 116 (94%) died, whereas of the 20 with an initial Glasgow Coma Scale score of 6–8, 14 (70%) died. There were no good outcomes, and only three moderate recoveries in patients who had initial scores of 8 or less. In those patients who survived long enough for intracranial pressure monitoring, intracranial hypertension predicted a very poor outcome. Computed tomographic scan characteristics such as midline shift, compression or obliteration of the mesencephalic cisterns, the presence of subarachnoid blood, intraventricular hemorrhage, and the presence of hyperdense or mixed-density lesions greater than 15 mL, either bilateral or unilateral, were all associated with a poor outcome. However, neither the caliber of gun nor the distance of the gun from the head significantly affected the risk of dying.
