In acute respiratory distress syndrome (ARDS) with severe hypoxemia or respiratory acidosis, veno-venous extracorporeal membrane oxygenation (VV-ECMO) ensures oxygenation and decarboxylation. Commonly, simultaneous cannulation of jugular and femoral veins is used for VV-ECMO. A recently introduced dual-lumen cannula for VV-ECMO promises single vessel access through the right internal jugular vein and patient ambulation. However, correct direction of the reinfusion jet toward the tricuspid valve during ECMO treatment requires more demanding cannula placement control. We present a new ultrasound-guided technique for the placement of a dual-lumen VV-ECMO cannula in a patient with ARDS and extreme obesity.
在伴有严重低氧血症或呼吸性酸中毒的急性呼吸窘迫综合征（ARDS）中，静脉-静脉体外膜肺氧合（VV-ECMO）可确保氧合和脱羧。通常，VV-ECMO 采用同时置管颈内静脉和股静脉。最近引入的一种用于 VV-ECMO 的双腔插管可通过右颈内静脉实现单血管入路和患者活动。然而，在 ECMO 治疗期间，为使再灌注射流朝向三尖瓣，需要更严格的插管位置控制。我们介绍了一种新的超声引导技术，用于在 ARDS 合并极度肥胖患者中放置 VV-ECMO 双腔插管。
