Crit Care:COVID-19患者体外膜氧合的疗效分析

2021-06-15 MedSci原创 MedSci原创

大多数COVID-19相关的ARDS患者接受了静脉ECMO支持治疗。在COVID19大流行的第一年,接受ECMO支持的COVID-19患者院内死亡率为 37.1%。

有几项研究报告了伴有严重急性呼吸窘迫综合征(ARDS)的2019年新冠肺炎(COVID-19) 患者使用体外膜肺氧合(ECMO)的情况。

近日,危重病医学领域权威杂志Critical Care上发表了一篇研究文章,研究人员进行了系统评价和荟萃分析,以指导临床决策和未来研究。

研究人员检索了MEDLINE、Embase、Cochrane和Scopus数据库,检索时间为2019年12月1日至2021年1月10日,确定了评估COVID-19 ARDS成年患者的ECMO疗效的观察性研究或随机临床试验。研究人员进行了随机效应荟萃分析和荟萃回归,使用Joanna Briggs研究所清单评估了偏倚风险,并使用GRADE方法评估了证据的确定性。该研究的主要结局为院内死亡率,次要结局是ECMO治疗和机械通气的持续时间、ECMO的撤机率和ECMO期间的并发症。

Meta分析结果

研究人员在荟萃分析中纳入了包含1896名患者的22项观察性研究。静脉ECMO是主要使用的模式 (98.6%)。ECMO支持的COVID-19患者(22项研究,1896名患者)的合并住院死亡率为37.1%(95%CI为32.3–42.0%,高确定性)。静脉ECMO组的合并死亡率为35.7%(95%CI为30.7-40.7%,高确定性)。Meta回归发现年龄和ECMO持续时间与死亡率增加相关。ECMO支持的持续时间(18项研究,1844名患者)为15.1天(95%CI为13.4-18.7)。67.6% (95%CI为50.5–82.7%) 的患者完成了ECMO撤机(17项研究,1412名患者)。该研究共报告了1583例ECMO并发症(18 项研究,1721名患者),肾脏并发症最为常见。

由此可见,大多数COVID-19相关的ARDS患者接受了静脉ECMO支持治疗。在COVID19大流行的第一年,接受ECMO支持的COVID-19患者院内死亡率为 37.1%,与非COVID-19相关的ARDS患者相似。年龄增加是死亡的危险因素。静脉ECMO似乎是对选定的COVID-19相关ARDS患者有效的干预手段。
