A 34-year-old man developed severe hypoxemia and hypercapnia due to acute respiratory distress during ventilator care after surgery with acute intracranial hemorrhage. Severe hypoxemia had not been corrected even with maximum extracorporeal membrane oxygenation (ECMO) flow and full ventilator settings. We applied a novel technique for the serial connection of two veno-venous ECMO circuits for optimal oxygen delivery and CO2 removal and could wean VV ECMO. The use of serial connection of two VV ECMO circuits may be considered worthwhile when severe hypoxemia or hypercapnia are not improved and the use of protective ventilators is not permitted.

一名 34 岁男性因急性颅内出血手术后呼吸机护理期间出现急性呼吸窘迫而出现严重低氧血症和高碳酸血症。即使使用最大体外膜肺氧合 (ECMO) 流量和全呼吸机设置，严重低氧血症仍未得到纠正。我们应用了一种新技术来串联两个静脉 - 静脉 ECMO 回路，以实现最佳的氧气输送和 CO2 去除，并且可以撤除 VV ECMO。当严重低氧血症或高碳酸血症未改善且不允许使用保护性呼吸机时，可考虑使用两个 VV ECMO 电路的串联连接。
