The emergence of computed tomography imaging more than 25 years ago led to characterization of acute respiratory distress syndrome (ARDS) as areas of relatively normal lung parenchyma juxtaposed with areas of dense consolidation and atelectasis. Given that this heterogeneity is often dorsally distributed, investigators questioned whether care for ARDS patients in the prone position would lead to improved mortality outcomes. This clinical review discusses the physiological rationale and clinical evidence supporting prone positioning in treating ARDS, in addition to its complications and contraindications.
25 多年前计算机断层扫描成像技术的出现,使得急性呼吸窘迫综合征(ARDS)的特征表现为相对正常的肺实质区域与致密实变和肺不张区域并存。鉴于这种异质性通常分布在背部,研究人员质疑对 ARDS 患者采用俯卧位护理是否会改善死亡率结局。本临床综述讨论了支持在治疗 ARDS 时采用俯卧位的生理原理和临床证据,以及其并发症和禁忌症。
