休克肺(休克并发急性肺功能衰竭)是休克患者最常见的死亡原因之一。另外,颅脑损伤及某些中枢神经疾患病人也常并发急性肺水肿(休克肺样病变)而死亡。休克肺的形成是肺微循环障碍的结局,其早期形态学改变是间质性肺水肿。肺的微循环障碍包括:①早期肺小血管痉挛;②广泛性肺小血管微栓塞;③肺毛细血管通透性增加。 Shock lung (shock complicated with acute lung failure) is one of the most common causes of death in patients with shock. In addition, patients with craniocerebral injury and some central nervous diseases often also die with acute pulmonary edema (shock lung disease). The formation of shock lung is the outcome of pulmonary microcirculation disorder, the early morphological changes of interstitial pulmonary edema. Pulmonary microcirculation disorders include: ① early pulmonary spasm; ② extensive pulmonary micro-embolization; ③ increased pulmonary capillary permeability.
