Abstract
OBJECTIVE: To present recent advances in stress gastritis prophylaxis in the critically ill and review considerations in selection of a prophylactic agent. DATA SOURCES: Information was obtained from MEDLINE search, reference lists from articles identified in search, and from review articles. STUDY SELECTION: Emphasis was placed on controlled trials conducted within the last 5 years. DATA EXTRACTION: All literature was assessed for methodology, results, and conclusions. Results of prospective, randomized trials, and meta-analyses are summarized. DATA SYNTHESIS: Histamine2-receptor antagonists, antacids, and sucralfate appear equally effective in preventing stress gastritis in the critically ill. A definitive cause–effect relationship between histamine2-receptor antagonists and increased incidence of nosocomial pneumonia has not yet been established. The indications for using a prophylactic agent and consideration in selecting an agent should include an evaluation of the following: Risk factors for gastritis including the type of intensive care patient, comparative efficacy, adverse effects, drug interactions, cost, and ease of administration. The least expensive, safest agent requiring minimal monitoring is sucralfate. Prevention of stress gastritis has never been shown to reduce morbidity or mortality significantly. CONCLUSIONS: Controversies still exist regarding the need to provide prophylaxis, the choice of an agent, and the relative importance of previously identified risk factors. Further well-designed studies are needed before consensus can be reached.
