Ethical challenges of adult ECMO.

The use of extracorporeal membrane oxygenation (ECMO) is expanding rapidly, and as more centres streamline their management policies, the bioethics literature on ECMO has been highlighting the ethical challenges of using an expensive, resource-intensive technology including its eligibility, duration of support, cost-effectiveness and societal repercussions. The absence of high-quality studies on long-term outcomes of ECMO survivors leads to multiple ethical problems involving patient autonomy, beneficence and clinical wisdom pertaining to its initiation, maintenance and termination. This article reviews some of the ethical challenges that affect decision-making during ECMO therapy and suggests an ethical framework that may help the treating team deal with such conundrums, when the patient does not recover despite being on ECMO. © Indian Association of Cardiovascular-Thoracic Surgeons 2020.
