Survivors of acute respiratory distress syndrome (ARDS) have long-term impairment of pulmonary function and health-related quality of life, but little is known of outcomes of ARDS survivors treated with extracorporeal membrane oxygenation. The aim of this study was to compare long-term outcomes of ARDS patients treated with or without extracorporeal membrane oxygenation.
A prospective, observational study of adults with ARDS (January 2013 to December 2015) was conducted at a single center. One year after discharge, survivors underwent pulmonary function tests, computed tomography of the chest, and health-related quality-of-life questionnaires.
Eighty-four patients (34 extracorporeal membrane oxygenation, 50 non-extracorporeal membrane oxygenation) were studied; both groups had similar characteristics at baseline, but comorbidity was more common in non-extracorporeal membrane oxygenation (23 of 50 vs. 4 of 34, 46% vs. 12%, P < 0.001), and severity of hypoxemia was greater in extracorporeal membrane oxygenation (median PaO2/FIO2 72 [interquartile range, 50 to 103] vs. 114 [87 to 133] mm Hg, P < 0.001) and respiratory compliance worse. At 1 yr, survival was similar (22/33 vs. 28/47, 66% vs. 59%; P = 0.52), and pulmonary function and computed tomography were almost normal in both groups. Non-extracorporeal membrane oxygenation patients had lower health-related quality-of-life scores and higher rates of posttraumatic stress disorder.
Despite more severe respiratory failure at admission, 1-yr survival of extracorporeal membrane oxygenation patients was not different from that of non-extracorporeal membrane oxygenation patients; each group had almost full recovery of lung function, but non-extracorporeal membrane oxygenation patients had greater impairment of health-related quality of life.
急性呼吸窘迫综合征（ARDS）幸存者的肺功能和健康相关生活质量长期受损，但接受体外膜氧合治疗的 ARDS 幸存者的结局知之甚少。本研究旨在比较接受和不接受体外膜氧合治疗的 ARDS 患者的长期结局。
在一家单中心进行了一项前瞻性、观察性研究，纳入了 2013 年 1 月至 2015 年 12 月期间的成人 ARDS 患者。出院后 1 年，幸存者接受了肺功能测试、胸部计算机断层扫描和健康相关生活质量问卷调查。
共纳入 84 例患者（34 例接受体外膜氧合治疗，50 例未接受体外膜氧合治疗）；两组患者在基线时具有相似的特征，但非体外膜氧合组的合并症更常见（23/50 比 4/34，46%比 12%，P<0.001），且体外膜氧合组的低氧血症严重程度更重（中位 PaO2/FIO2 72[四分位间距，50103]比 114[87133]mmHg，P<0.001），呼吸顺应性更差。1 年时，生存率相似（22/33 比 28/47，66%比 59%；P=0.52），两组的肺功能和计算机断层扫描均基本正常。非体外膜氧合组的健康相关生活质量评分较低，创伤后应激障碍发生率较高。
尽管入院时呼吸衰竭更严重，但体外膜氧合治疗患者的 1 年生存率与非体外膜氧合治疗患者无差异；两组的肺功能均基本完全恢复，但非体外膜氧合组的健康相关生活质量受损更严重。
