Abstract
We describe a case of severe sepsis in a 14-year-old boy who was treated with veno-arterial (VA) extracorporeal membrane oxygenation (ECMO) support. The haemodynamic challenges inherent to femoro-femoral VA ECMO are discussed, and the use of ultrasonography to define the location of the mixing zone in the abdominal aorta is demonstrated. We propose that the use of ultrasound is able to assist clinicians in understanding perfusion of abdominal organs in the presence of suspected differential oxygenation.
摘要
我们描述了一名14岁男孩发生严重脓毒症并接受静脉-动脉（VA）体外膜肺氧合（ECMO）支持治疗的病例。文中讨论了股-股VA ECMO固有的血流动力学挑战，并展示了如何使用超声来确定腹主动脉内混合区的位置。我们认为，在存在疑似氧合差异的情况下，超声的使用能够帮助临床医生了解腹部器官的灌注情况。
