The aspiration of stomach contents is a common clinical problem of concern to all physicians. Its consequences are varied, depending on the amount and distribution of the aspirate, its pH, and the presence or absence of food, particulate matter, and bacteria. Because multiple factors are involved, aspiration of stomach contents can lead to several distinct syndromes of pulmonary injury, all of which unfortunately have been labeled "aspiration pneumonitis." We review the pathophysiology of each of these syndromes and discuss important diagnostic and therapeutic consequences.
胃内容物误吸是所有医生都关注的常见临床问题。其后果各不相同，取决于误吸物的量和分布、pH值，以及是否存在食物、颗粒物和细菌。由于涉及多种因素，胃内容物误吸可导致几种不同的肺损伤综合征，不幸的是，所有这些综合征都被称为“误吸性肺炎”。我们回顾了每种综合征的病理生理学，并讨论了重要的诊断和治疗结果。
