This literature review compares the efficacy of the two most commonly recommended bedside tests for detecting aspiration in tube-fed patients: (1) adding dye to the formula and observing for its appearance in tracheobronchial secretions, and (2) using glucose oxidase reagent strips to test tracheobronchial secretions for glucose-containing enteral formula. The review also describes potential problems and cost associated with each test. Several studies indicate that the dye method is far less sensitive than the glucose reagent method; further, there are anecdotal reports of potential harm to patients when dye is added to tube feedings. Specificity of the glucose method has been challenged by several authors; also, cost is probably greater with this method.
（1）在配方奶中添加染料并观察其在气管支气管分泌物中的出现情况，以及（2）使用葡萄糖氧化酶试纸检测气管支气管分泌物中是否含有含葡萄糖的肠内配方奶。该综述还描述了每种检查方法的潜在问题和成本。几项研究表明，染料法的敏感性远低于葡萄糖试剂法；此外，有轶事报道称，在管饲中添加染料可能对患者造成伤害。几位作者对葡萄糖法的特异性提出了质疑；而且，这种方法的成本可能更高。
