成人呼吸窘迫综合征(以下简称ARDS)的发病机理尚未完全阐明,临床上仍缺乏卓有成效的治疗措施。故加强对本综合征的基础理论研究实为必要。本文将分述ARDS的病因、发病机理、病理生理改变及实验研究的近况。病因临床上很多致病因素均可诱发ARDS。引起本症的基础疾病有50余种。1976年Hopewell将ARDS的病因分为九大类:(1)体克;(2)感染;(3)创伤;(4)吸入液体;(5)用药过量:使用过 The pathogenesis of adult respiratory distress syndrome (hereinafter referred to as ARDS) has not yet been fully elucidated and clinically still lack of effective treatment. Therefore, strengthening the basic theory of this syndrome is necessary. This article will describe the etiology, pathogenesis, pathophysiological changes ARDS and experimental research status. Etiology Many pathogenic factors can induce ARDS clinically. Caused by the disease more than 50 kinds of basic diseases. Hopewell in 1976 will be the cause of ARDS is divided into nine categories: (1) body grams; (2) infection; (3) trauma; (4) inhalation of liquid; (5) overdose: used
