自从1967年 Ashbaugh 等报告12例急剧发生的低氧血症伴顺应性降低的成人呼吸窘迫综合征以来,该综合征已成为一种独特的临床病征。它的特征是:以往未有肺部疾患,难于预测呼吸窘迫的发生,常发于外伤、手术或感染等疾患的基础上,而且对习用的救治方法反应欠佳,可导致死亡。1.Kaplan 等认为革兰氏阴性杆菌菌血症之后发生的成人呼吸窘迫综合征的机会很大。该氏所观察的86很革兰氏阴性杆菌菌血症病例中有20例(23％)出现成人呼吸窘迫 Since 1967, Ashbaugh et al reported 12 cases of rapid onset of hypoxemia with reduced compliance of adult respiratory distress syndrome, the syndrome has become a unique clinical symptoms. It is characterized by the fact that in the past, there was no lung disease and it was difficult to predict the occurrence of respiratory distress, which often occurred on the basis of trauma, surgery or infection, and the poor response to conventional treatment methods could result in death. 1. Kaplan et al. Have shown a great chance of developing adult respiratory distress syndrome after Gram-negative bacteremia. The 86 observed cases of Gram-negative bacilli in 20 (23%) cases of adult respiratory distress
