What is a common consequence of prolonged ECMO use?

Prolonged use of ECMO is associated with an increased risk of thromboembolic events. This occurs due to several factors, including the presence of foreign surfaces within the ECMO circuit, the flow dynamics of the system, and the anticoagulation management required during ECMO. The flow of the blood through the circuit, along with potential activation of the coagulation cascade, can contribute to the formation of clots, which can subsequently lead to thromboembolic complications, such as ischemic strokes or limb ischemia.

Monitoring and managing anticoagulation is a crucial aspect of ECMO care to mitigate this risk; however, the inherent risks associated with the mechanical support, especially over an extended duration, can lead to a higher likelihood of these adverse events. Recognizing and preventing thromboembolic events is vital for the successful outcomes of patients on ECMO. This understanding emphasizes the importance of careful management and regular monitoring throughout the duration of ECMO therapy.
