Stress-related gastrointestinal bleeding is known to occur in approximately 25 percent of untreated seriously ill patients, but with appropriate prophylaxis is largely preventable. Since the treatment of stress bleeding is generally unsatisfactory and has a high mortality, routine prophylaxis should be instituted for susceptible patients. Multiple mechanisms contribute to stress ulcer formation, the most important of which appear to be mucosal ischemia and the inability to control back-diffused hydrogen. Antacids and histamine2-blocking agents are presently the cornerstone of effective prophylaxis, but because they have been implicated as contributors to nosocomial pneumonias due to bacterial overgrowth in the stomach, investigation is ongoing into such alternative prophylactic agents as sucralfate and prostaglandins that do not alter the normal gastric acidity. This article presents a review of the literature on the development and prevention of stress ulcer disease.
