十几年前,急性出血坏死性胰腺炎病人大多数死于休克和肾功能衰竭。近来随着人们对休克本质认识的深化和透析技术的进步,病人一般能渡过这些早期并发症,但随后不少病人出现急性呼吸功能不全,表现为进行性的呼吸窘迫和低氧血症,预后很差。据不同作者报道,其发生率在67～58%之间。最初,人们对继发于胰腺炎的呼吸窘迫综合征(RDS)认识不清,往往与其它非特异性并发症混为一谈。1977年 Mckenna 等认真分析总结了前 More than ten years ago, the majority of patients with acute hemorrhagic necrotizing pancreatitis died of shock and renal failure. Recently, with the deepening of people’s understanding of the nature of shock and the progress of dialysis technology, patients can generally survive these early complications, but then many patients with acute respiratory insufficiency, manifested as progressive respiratory distress and hypoxemia, The prognosis is poor. According to different authors, the incidence was between 67 and 58%. Initially, people with respiratory distress syndrome (RDS) secondary to pancreatitis were not well understood and often confused with other nonspecific complications. In 1977, Mckenna and other serious analysis summarized the former
