Abstract:

In recent years, the application of extracorporeal membrane oxygenation (ECMO) in patients with severe respiratory and circulatory dysfunction has become increasingly popular, but hemodynamics are very unstable in these patients. Therefore, hemodynamic monitoring and treatment are very important in the management of patients receiving ECMO. Improving microcirculation and tissue perfusion is the goal of ECMO and also the ultimate goal of hemodynamic monitoring and treatment. ECMO can increase systemic tissue flow and improve the macrocirculatory hemodynamics, but the improvement of macrocirculation does not mean that the microcirculation is also improved, and microcirculatory hemodynamics are closely related to the prognosis. Therefore, the hemodynamics of ECMO patients need to be monitored in real time and comprehensively judged. Maintaining an appropriate target blood pressure is a prerequisite. Ensuring a stable and sufficient flow is the key to tissue perfusion. It is also necessary to evaluate the microcirculation through various monitoring methods and take more available treatments to improve microcirculation, thereby improving the prognosis of patients with ECMO.
