Objective: Iatrogenic aspiration is a major cause of mortality and morbidity in hospitalized patients and breathing and feeding tubes increase the risk of aspiration in this group. The purpose of this study was to determine what factors predicted aspiration in mechanically ventilated patients receiving enteral nutrition. A secondary purpose was to determine which clinical method (glucose or blue dye) most accurately detected aspiration. Design & Sample: In this prospective intervention study predictive factors for aspiration were examined in 14 mechanically ventilated intubated patients. Variables: Two methods were used to detect aspiration a positive blue dye and glucose test. Predicative variables for aspiration included size of feeding tube, APACHE II score, patient position, sedation, and head of bed elevation were analyzed using logistic regression. Aspiration was defined as a positive glucose or blue test on bronchotracheal secretions. Findings: Of the 139 total observations performed on the sample, 47 incidents of aspiration were identified among 10 patients (33.3% occurrence rate in 71% of the sample). Glucose reagents (chemstrip bG and Accu-chek were significantly better in detecting aspiration events than Diastix or blue dye methods (p=0.0001). Large bore feeding tubes were associated with a higher incidence of aspiration (p=0.04). Conclusions: Aspiration occurred frequently in intubated patients receiving enteral feedings and those feed through large bore tubes were at a significantly higher risk. Glucose reagent methods were most accurate in detecting aspiration events. Implications: Accurate but cost effective methods to detect aspiration can be initiated by nurses to prevent complications in mechanically ventilated patients.
