Expert consensus on prevention and treatment of lower limb ischemia during transfemoral veno-arterial extracorporeal membrane oxygenation therapy in adults in China (2023)

Abstract

Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is an important technique for the treatment of patients with severe circulatory failure, and is used in a wider range. Canulation through the femoral artery is simple and convenient, which has become the most commonly used canulation method of VA-ECMO for adults. Lower limb ischemia is a common complication in transfemoral VA-ECMO therapy, which will seriously affect the prognosis and quality of life of patients. In order to standardize the lower limb ischemia management during VA-ECMO treatment and reduce disability and mortality, Extracorporeal Life Support Professional Committee of Chinese Medical Doctor Association and Extracorporeal Life Support Professional Committee of Shandong Physician Association organized multidisciplinary medical experts with ECMO proficiency from China to develop the Expert consensus on prevention and treatment of lower limb ischemia during transfemoral veno-arterial extracorporeal membrane oxygenation therapy in adults in China (2023), based on literature review and their clinical practice experience. This consensus is expected to provide valuable reference for the prevention, monitoring and treatment of lower limb ischemia during femoral artery VA-ECMO treatment.
