About

Microaspiration of contaminated oropharyngeal secretions and gastric contents frequently occurs in intubated critically ill patients, and plays a major role in the pathogenesis of ventilator-associated pneumonia. Quantitative pepsin measurement in tracheal aspirates would be useful in diagnosing microaspiration of gastric contents in intubated critically ill patients. Technetium 99m labelled enteral feeding is the gold standard for the diagnosis of microaspiration. The investigators hypothesized that tracheal pepsin measurement is a good diagnosis marker of microaspiration compared to the gold standard.
