Extracorporeal Membrane Oxygenation (ECMO)

Extracorporeal Membrane Oxygenation (ECMO) is a life-saving technique used in critical emergency situations when a patient’s heart and lungs are unable to function adequately. ECMO provides temporary respiratory and cardiac support by oxygenating the blood and removing carbon dioxide outside the body, allowing the heart and lungs to rest and recover. In severe respiratory distress, ECMO can provide respiratory support by bypassing the lungs and oxygenating the blood directly. It involves the insertion of large cannulas into major blood vessels, typically in the neck or groin, which are connected to a specialized ECMO circuit. The circuit pumps blood from the patient, oxygenates it using a membrane oxygenator, removes carbon dioxide, and returns the oxygenated blood to the patient’s body.

Here are several examples of how ECMO has shown significant improvements in survival rates in various emergency situations:

• Severe Respiratory Distress: In cases of severe acute respiratory distress syndrome (ARDS) or respiratory failure, ECMO can provide life-saving support when conventional mechanical ventilation is insufficient. By improving oxygenation and CO2 removal, ECMO allows time for the underlying lung condition to heal or for other interventions, such as lung transplantation, to be considered.
• Cardiac Arrest: In select cases of refractory cardiac arrest, ECMO can be initiated to provide temporary circulatory support and maintain vital organ perfusion. ECMO allows for ongoing cardiopulmonary resuscitation (CPR) while providing oxygenated blood to vital organs, increasing the chances of successful resuscitation.
• Bridge to Transplantation: In emergency situations where a patient’s condition rapidly deteriorates, ECMO can stabilize the patient and sustain them until a suitable organ becomes available for transplantation. This bridge-to-transplantation strategy has significantly improved survival rates for patients awaiting organ transplantation.
• Post-cardiotomy Shock: ECMO has been used to support patients experiencing post-cardiotomy shock, a condition where the heart fails to function adequately after cardiac surgery. ECMO provides temporary mechanical circulatory support, allowing the heart to recover from the surgical insult and restoring cardiac function.
