Bronchial secretions from 21 patients with moderate to severe chest infections were obtained by transtracheal aspiration. Six seriously ill patients showed greatly increased levels of amylase activity in the bronchial secretions compared with those found in the 15 less ill patients. This amylase was almost certainly derived from oropharyngeal contents and its presence suggests that aspiration may be more common in comatose and semi-comatose patients than is generally appreciated.
通过经气管抽吸获取了21例中重度胸部感染患者的支气管分泌物。与15例病情较轻的患者相比,6例重症患者支气管分泌物中的淀粉酶活性水平大幅升高。这种淀粉酶几乎肯定来自口咽内容物,其存在表明昏迷和半昏迷患者中的误吸可能比普遍认为的更为常见。
