Background
External membrane lung oxygenation (extracorporeal membrane oxygenation, ECMO), abbreviated as membrane lung, is a new technique for rescuing life threatening patients. The ECMO is an improved artificial heart-lung machine, and the most central part is a membrane lung and a blood pump which respectively play the roles of the artificial lung and the artificial heart. During ECMO operation, blood is drawn from veins, oxygen is absorbed through the lungs of the membranes, carbon dioxide is removed, and the gas exchanged blood is returned to veins (VV-ECMO) or arteries (VA-ECMO) under the assistance of a pump. The former is mainly used for external respiratory support, and the latter can be used for external respiratory support and cardiac support because the blood pump can replace the blood pumping function of the heart.
Among them, VA-ECMO is widely used clinically because of simple and convenient operation and rapid start of cardiopulmonary support. When the VA-ECMO is implemented, the femoral artery catheterization is preferred in the VA-ECMO for adults because the femoral artery of the human body is shallow in position and convenient to operate, and the catheterization can be directly performed through percutaneous puncture or incision without influencing the cardiopulmonary resuscitation. However, femoral artery cannulation can block blood flow from the lower limb of the femoral artery perfusion, resulting in ischemia of the lower limb, and even amputation of the limb is required for serious ischemia, which is also a common complication of VA-ECMO. In order to reduce the occurrence rate of the complications, the conventional solution is to additionally puncture a lower limb perfusion tube, but the operation of the method is very troublesome, the damage of femoral artery is aggravated, and the possibility of vascular complications is increased.
