Coronavirus disease (COVID-19) started in Wuhan (China) at the end of 2019, and then increased rapidly. In patients with severe acute respiratory distress syndrome (ARDS) caused by COVID-19, venovenous extracorporeal membrane oxygenation (VV-ECMO) is considered a rescue therapy that provides adequate gas exchange. The way in which mechanical ventilation is applied during VV-ECMO is not clear, however it is associated with prognosis. Currently, the mortality rate of COVID-19 patients that receive VV-ECMO stands at approximately 50%. Here, we report three patients that successfully recovered from COVID-19-induced ARDS after VV-ECMO and implementation of an ultra-protective ventilation. This ventilation strategy involved maintaining a peak inspiratory pressure of ≤20 cmHO and a positive end-expiratory pressure (PEEP) of ≤ 10 cmHO, which are lower values than have been previously reported. Thus, we suggest that this ultra-protective ventilation be considered during VV-ECMO as it minimizes the ventilator-induced lung injury.
冠状病毒病(COVID-19)于 2019 年底在中国武汉开始爆发,随后迅速蔓延。在 COVID-19 引起的严重急性呼吸窘迫综合征(ARDS)患者中,静脉-静脉体外膜肺氧合(VV-ECMO)被认为是一种提供充分气体交换的抢救治疗方法。然而,在 VV-ECMO 期间应用机械通气的方式尚不清楚,但其与预后相关。目前,接受 VV-ECMO 的 COVID-19 患者的死亡率约为 50%。在这里,我们报告了三例 COVID-19 诱导的 ARDS 患者在接受 VV-ECMO 治疗和实施超保护性通气后成功康复的病例。这种通气策略包括将吸气峰压维持在≤20cmH2O 和呼气末正压(PEEP)≤10cmH2O,这些值低于之前报道的值。因此,我们建议在 VV-ECMO 期间考虑这种超保护性通气,因为它可以最大程度地减少呼吸机引起的肺损伤。
