Severe cases of coronavirus disease 2019 (COVID-19) cannot be adequately managed with mechanical ventilation alone. The role and outcome of extracorporeal membrane oxygenation (ECMO) in the management of COVID-19 is currently unclear. Eight COVID-19 patients have received ECMO support in Shanghai with seven with venovenous (VV) ECMO support and one veno arterial (VA) ECMO during cardiopulmonary resuscitation. As of March 25, 2020, four patients died (50% mortality), three patients (37.5%) were successfully weaned off ECMO after 22, 40, and 47 days support, respectively, but remain on mechanical ventilation. One patient is still on VV ECMO with mechanical ventilation. The partial pressure of oxygen/fractional of inspired oxygen ratio before ECMO initiation was between 54 and 76, and all were well below 100. The duration of mechanical ventilation before ECMO ranged from 4 to 21 days. Except the one emergent VA ECMO during cardiopulmonary resuscitation, other patients were on ECMO support for between 18 and 47 days. In conclusion, ensuring effective, timely, and safe ECMO support in COVID-19 is key to improving clinical outcomes. Extracorporeal membrane oxygenation support might be an integral part of the critical care provided for COVID-19 patients in centers with advanced ECMO expertise.
严重的 2019 冠状病毒病(COVID-19)病例不能仅通过机械通气进行充分治疗。体外膜氧合(ECMO)在 COVID-19 治疗中的作用和结果目前尚不清楚。上海有 8 例 COVID-19 患者接受了 ECMO 支持,其中 7 例采用静脉-静脉(VV)ECMO 支持,1 例在心肺复苏期间采用静脉-动脉(VA)ECMO。截至 2020 年 3 月 25 日,4 例患者死亡(50%的死亡率),3 例患者(37.5%)分别在接受 ECMO 支持 22、40 和 47 天后成功撤机,但仍需机械通气。1 例患者仍在接受 VV ECMO 和机械通气。启动 ECMO 前的氧分压/吸入氧分数比值在 54 至 76 之间,均远低于 100。在 ECMO 之前进行机械通气的持续时间从 4 天到 21 天不等。除了心肺复苏期间进行的紧急 VA ECMO 外,其他患者的 ECMO 支持时间为 18 至 47 天。总之,确保 COVID-19 患者获得有效、及时和安全的 ECMO 支持是改善临床结局的关键。ECMO 支持可能是具有先进 ECMO 专业知识的中心为 COVID-19 患者提供重症监护的重要组成部分。
