ARDS目前仍然是住院患者的重要死亡原因。美国每年有15万ARDS患者,有关死亡率的报道10%～90%不等,这与ARDS没有明确统一的诊断标准密切相关。以往的诊断际准条件高,满足条件时,患者肺损伤已相当严重,在早期常不能得到及时诊断和处理,使患者错过治疗时机,增加治疗难度,这可能是ARDS死亡率居高不下的重要原因。 ARDS is still an important cause of death in hospitalized patients. There are 150,000 ARDS patients in the United States each year, and the related mortality rates range from 10% to 90%. This is closely related to the lack of a clear and uniform diagnostic criteria for ARDS. In the past, when the diagnostic criteria were high, when the conditions were met, the patient’s lung injury was already quite serious and often could not be diagnosed and treated in an early stage. Patients missed the timing of treatment and increased the difficulty of treatment. This may be an important reason for the high ARDS mortality rate the reason.
