April 7, 2020 — The U.S. Food and Drug Administration (FDA) has issued guidance to provide a policy to help expand the availability of devices used in extracorporeal membrane oxygenation (ECMO) therapy to address the novel coronavirus (COVID-19, SARS-CoV-2) public health emergency.
ECMO systems are used for long-term respiratory/cardiopulmonary failure and provide assisted extracorporeal circulation and physiologic gas exchange of the patient’s blood for more than six hours. The technology can oxygenate a severely sick COVID-19 pneumonia patient's blood without the need to transfer the oxygen through fluid filled lungs.
As a sudden acute respiratory syndrome, COVID-19 can trigger acute respiratory failure and/or acute cardiopulmonary failure. Under these conditions, the FDA states in the new policy extracorporeal oxygenation can now be used for greater than six hours as tool for treating patients. The FDA said it recognizes the importance and utility of increased availability of ECMO devices for patients during the COVID-19 emergency.
The FDA included a list all the devices that it identified as being technologically capable of being used for ECMO therapy that can now be used for COVID-19 patients.
The FDA also states in the document it does not intend to object to limited modifications to the indications and design of FDA-cleared or FDA-approved ECMO devices and cardiopulmonary bypass devices listed during the declared public health emergency. As long as any modifications do not create an undue risk
As a general best practice, because cardiopulmonary bypass circuit systems might incorporate multiple components, it is recommended that compatibility between components (such as flow rates, coatings, intended patient population) should be considered prior to configuring the circuit for clinical use, the FDA recommends. This includes modifications to cardiopulmonary bypass devices and ECMO devices, such as dimension of cannulae, tubing, filters, connectors, or other accessories to support use in an ECMO circuit that do not affect the flow rate of blood throughout the circuit.
This policy is intended to remain in effect only for the duration of the public health emergency related to COVID-19 declared by the Department of Health and Human Services (HHS). This period will include any renewals made by the HHS secretary.
The FDA included notice of this policy chang in the document "Enforcement Policy for Extracorporeal Membrane Oxygenation and Cardiopulmonary Bypass Devices During the Coronavirus Disease 2019 (COVID-19) Public Health Emergency."
