Analytic Reviews : Aspiration Pneumonitis: Patient Risk Factors, Prevention, and Management

Abstract

Occurrence of aspiration pneumonitis, the morbid con dition that often follows aspiration of gastric contents, has been documented for over 40 years. A number of risk factors that predispose patients to acid aspiration have been identified. The acidity of the gastric fluid and the volume of the aspirate are high-risk factors that de termine the severity of the pneumonitis. In this review I discuss those conditions that predispose patients to as piration and subsequent development of pneumonitis as well as current strategies for prevention and treatment.
