Prevention of acute gastrointestinal complications after severe head injury: a controlled trial of cimetidine prophylaxis

Abstract

Cimetidine prophylaxis significantly reduced the risk of gastrointestinal bleeding after severe head injury in this prospective, double-blind clinical trial. Cimetidine effectively reduced both the volume and the acidity of gastric secretions after brain injury without producing adverse side effects. The most common endoscopic finding was superficial, erosive, mucosal lesions in the proximal stomach. Cimetidine prophylaxis was not shown to reduce the incidence of these lesions in this study but did diminish their severity and the likelihood that they would complicate the management of these patients.
