急性肺损伤和急性呼吸窘迫综合征研究现状与展望

急性肺损伤和急性呼吸窘迫综合征是指由心源性以外的各种肺内外致病因素所导致的急性、进行性缺氧性呼吸衰竭。近年来，对急性肺损伤和急性呼吸窘迫追综合征的命名和定义进行了更新和规范，对发病机制有了新的认识，提出了临床诊断标准和综合治疗措施。随着对急性肺损伤和急性呼吸窘迫综合征的深入研究，从炎症失控、调控着手去认识发病机制，采取针对性治疗，可望取得突破性进展。

THE STATUS QUO AND PROSPECT OF ACUTE LUNG INJURY AND ACUTE RESPIRATORY DISTRESS SYNDROME

Acute lung injury/acute respiratory distress syndrome (ALI/ARDS) refers to acute progressive respiratory failure with stubborn hypoxemia induced by different predisposing factors except cardiogenic causes. The definition of ALI/ARDS have been renewed and standardized in recent years, thus there is a new understanding in the pathogenesis of ALI/ARDS. The new diagnostic criteria and the combining therapeutic measures of ALI/ARDS have been proposed. With the progress in research pertaining to ALI/ARDS and the new insight into the pathogenesis of intractable systemic inflammation, new therapeutic measures directing at controlling and regulating inflammatory responses may be expected to achieve a breakthrough in the treatment of ALI/ARDS.
