Objective To estimate the effect of extracorporeal membrane oxygenation (ECMO) compared with conventional mechanical ventilation on outcomes of patients with covid-19 associated respiratory failure. Design Observational study. Setting 30 countries across five continents, 3 January 2020 to 29 August 2021. Participants 7345 adults admitted to the intensive care unit with clinically suspected or laboratory confirmed SARS-CoV-2 infection. Interventions ECMO in patients with a partial pressure of arterial oxygen to fraction of inspired oxygen (PaO2/FiO2) ratio <80 mm Hg compared with conventional mechanical ventilation without ECMO. Main outcome measure The primary outcome was hospital mortality within 60 days of admission to the intensive care unit. Adherence adjusted estimates were calculated using marginal structural models with inverse probability weighting, accounting for competing events and for baseline and time varying confounding. Results 844 of 7345 eligible patients (11.5%) received ECMO at any time point during follow-up. Adherence adjusted mortality was 26.0% (95% confidence interval 24.5% to 27.5%) for a treatment strategy that included ECMO if the PaO2/FiO2 ratio decreased <80 mm Hg compared with 33.2% (31.8% to 34.6%) had patients received conventional treatment without ECMO (risk difference –7.1%, 95% confidence interval –8.2% to –6.1%; risk ratio 0.78, 95% confidence interval 0.75 to 0.82). In secondary analyses, ECMO was most effective in patients aged <65 years and with a PaO2/FiO2 <80 mm Hg or with driving pressures >15 cmH2O during the first 10 days of mechanical ventilation. Conclusions ECMO was associated with a reduction in mortality in selected adults with covid-19 associated respiratory failure. Age, severity of hypoxaemia, and duration and intensity of mechanical ventilation were found to be modifiers of treatment effectiveness and should be considered when deciding to initiate ECMO in patients with covid-19. An independent research team collects data of the international, multicentre COVID-19 Critical Care Consortium registry. Deidentified registry data may be obtained for research purposes on approval of a formal proposal. Derived data supporting the findings of this study may be available from the corresponding author upon request.

急性covid-19相关呼吸衰竭患者的静脉体外膜肺氧合:比较有效性研究

目的 评估体外膜肺氧合 (ECMO) 与传统机械通气相比对 covid-19 相关呼吸衰竭患者预后的影响。设计观察研究。2020 年 1 月 3 日至 2021 年 8 月 29 日,分布在五大洲的 30 个国家。参与者 7345 名临床疑似或实验室确诊感染 SARS-CoV-2 的成年人入住重症监护室。与没有 ECMO 的传统机械通气相比,动脉氧分压与吸入氧分数 (PaO2/FiO2) 比 <80 mm Hg 的患者的干预 ECMO。主要结果测量 主要结果是入住重症监护病房后 60 天内的住院死亡率。使用具有逆概率加权的边际结构模型计算依从性调整估计,考虑竞争事件以及基线和时变混杂因素。结果 7345 名符合条件的患者中有 844 名(11.5%)在随访期间的任何时间点接受了 ECMO。如果 PaO2/FiO2 比值降低 <80 mm Hg,则包括 ECMO 在内的治疗策略的依从性调整死亡率为 26.0%(95% 置信区间为 24.5% 至 27.5%),而接受常规治疗的患者为 33.2%(31.8% 至 34.6%)没有 ECMO 的治疗(风险差异 –7.1%,95% 置信区间 –8.2% 至 –6.1%;风险比 0.78,95% 置信区间 0.75 至 0.82)。在二次分析中,ECMO 对年龄 <65 岁且 PaO2/FiO2 <80 mm Hg 或驱动压 > 的患者最有效 在机械通气的前 10 天,15 cmH2O。结论 ECMO 与 COVID-19 相关呼吸衰竭的选定成人死亡率降低相关。年龄、低氧血症的严重程度以及机械通气的持续时间和强度被发现是治疗效果的调节因素,在决定对 covid-19 患者启动 ECMO 时应考虑这些因素。一个独立的研究团队收集国际多中心 COVID-19 重症监护联盟登记处的数据。在正式提案获得批准后,可出于研究目的获取去识别化的注册数据。支持本研究结果的衍生数据可根据要求从相应作者处获得。结论 ECMO 与 COVID-19 相关呼吸衰竭的选定成人死亡率降低相关。年龄、低氧血症的严重程度以及机械通气的持续时间和强度被发现是治疗效果的调节因素,在决定对 covid-19 患者启动 ECMO 时应考虑这些因素。一个独立的研究团队收集国际多中心 COVID-19 重症监护联盟登记处的数据。在正式提案获得批准后,可出于研究目的获取去识别化的注册数据。支持本研究结果的衍生数据可根据要求从相应作者处获得。结论 ECMO 与 COVID-19 相关呼吸衰竭的选定成人死亡率降低相关。年龄、低氧血症的严重程度以及机械通气的持续时间和强度被发现是治疗效果的调节因素,在决定对 covid-19 患者启动 ECMO 时应考虑这些因素。一个独立的研究团队收集国际多中心 COVID-19 重症监护联盟登记处的数据。在正式提案获得批准后,可出于研究目的获取去识别化的注册数据。支持本研究结果的衍生数据可根据要求从相应作者处获得。发现机械通气的持续时间和强度是治疗效果的调节因子,在决定对 covid-19 患者启动 ECMO 时应考虑这些因素。一个独立的研究团队收集国际多中心 COVID-19 重症监护联盟登记处的数据。在正式提案获得批准后,可出于研究目的获取去识别化的注册数据。支持本研究结果的衍生数据可根据要求从相应作者处获得。发现机械通气的持续时间和强度是治疗效果的调节因子,在决定对 covid-19 患者启动 ECMO 时应考虑这些因素。一个独立的研究团队收集国际多中心 COVID-19 重症监护联盟登记处的数据。在正式提案获得批准后,可出于研究目的获取去识别化的注册数据。支持本研究结果的衍生数据可根据要求从相应作者处获得。
