BEDSIDE METHODS FOR DETECTING ASPIRATION IN TUBE-FED PATIENTS

This literature review compares the efficacy of the two most commonly recommended bedside tests for detecting aspiration in tube-fed patient s: (1) adding dye to the formula and observing for its appearance in t racheobronchial secretions, and (2) using glucose oxidase reagent stri ps to test tracheobronchial secretions for glucose-containing enteral formula. The review also describes potential problems and cost associa ted with each test. Several studies indicate that the dye method is fa r less sensitive than the glucose reagent method; further, there are a necdotal reports of potential harm to patients when dye is added to tu be feedings. Specificity of the glucose method has been challenged by several authors; also, cost is probably greater with this method.
