呼吸困难综合征(Respirafory Dis fress Synd rom,RDS),有人称为“损伤后肺功能不全”。指继发于休克或各种严重损伤经复苏后突然或逐渐出现的肺功能不全综合征。各家常因其发病原因不同而命名各异,继发于休克者称休克肺综合征,见于体外循环术后者,称肺灌注后综合征。C.G.Aschbaugh等则称为呼吸困难综合征(RDS)此病如不及时诊治,死亡率甚高。D.G.Aschbaugh治疗51例各种原因引起的RDS,存活者仅21例(41％),因此,对此病应引起足够的重视。 [发病机理] 一、肺微循环功能障碍肺微循环与其它器官相比,有其特性:
Respiratory distress syndrome (Respirafory Dis fress Synd rom, RDS), was called “post-injury lung insufficiency.” Refers to secondary to shock or serious injury after repeated recovery of sudden or progressive pulmonary insufficiency syndrome. Each often because of their different causes of different named, secondary to shock in patients with Shock Lung syndrome, found in those after cardiopulmonary bypass, said lung perfusion syndrome. C.G.Aschbaugh et al, known as dyspnoea syndrome (RDS), if not timely diagnosis and treatment of the disease, the mortality rate is very high. D.G.Aschbaugh treatment of 51 cases of various causes of RDS, only 21 cases of survival (41%), therefore, the disease should cause enough attention.
