STRESS ULCERS OCCUR frequently in intensive care unit patients who have intracranial disease. After major physiological stress, endoscopic evidence of mucosal lesions of the gastrointestinal tract appears within 24 hours of injury; 17% of these erosions progress to clinically significant bleeding. Gastrointestinal hemorrhage has been associated with mortality rates of up to 50%. The pathogenesis of stress ulcers may not be completely understood, but gastric acid and pepsin appear to play significant roles. Antacids, H2 antagonists, and sucralfate are effective prophylactic agents in the medical/surgical intensive care unit. Appropriate therapy for neurosurgical patients remains unclear, however. This review summarizes the current literature regarding the pathogenesis and therapy of stress ulcers in neurosurgical patients.
