新生儿呼吸窘迫综合征 (ＮＲＤＳ)又名肺透明膜病 ,为多见于早产儿的疾病 ,孕周 32周 (ｗ)者易于发病 ,2 8ｗ者发病率更高。主要原因是肺发育不成熟 ,肺表面活性物质 (ＰＳ)缺乏致使生后肺泡弥漫性不张 ,透明膜形成 ,肺顺应性下降 ,功能残气量降低。缺氧、低血压、低体温均影 Neonatal respiratory distress syndrome (NRDS), also known as hyaline membrane disease, is more common in premature children’s disease, gestational age 32 weeks (w) are prone to disease, 28 cases of a higher incidence. The main reason is immature lung development, lack of pulmonary surfactant (PS) resulting in diffuse atelectasis of the alveoli after birth, the formation of a clear film, decreased lung compliance and decreased functional residual capacity. Hypoxia, hypotension, hypothermia were shadows
