Beta Blockade in in Traumatic Brain Injury

The purpose of this study is test the effect of beta-adrenergic blockade on mortality in patients with traumatic brain injury with the hypothesis being that the addition of beta blockade to the treatment regime of this patient population will lower mortality and supress the catecholamine surge that accompanies traumatic brain injury as compared to those who do not receive beta blockade. Half the patients will be randomized to receive propranolol and half will be randomized to receive no beta blocker.
