Clinical review: Extracorporeal membrane oxygenation

Area of Science:

• Critical Care Medicine
• Respiratory Medicine
• Cardiopulmonary Support

Background:

• The H1N1 influenza pandemic highlighted the efficacy of extracorporeal membrane oxygenation (ECMO) for severe hypoxemic respiratory failure.
• Real-world outcomes from the pandemic significantly drove global adoption of membrane oxygenation technology.
• Experience gained in using ECMO as a rescue therapy revealed its strengths and manageable technical aspects, prompting expanded clinical applications.

Purpose of the Study:

• To review the expanded indications for veno-venous ECMO.
• To emphasize the importance of considering potential complications associated with ECMO therapy.

Main Methods:

• Review of clinical outcomes and expanded indications for ECMO following the H1N1 pandemic.
• Analysis of current applications of veno-venous ECMO in various respiratory conditions.

Main Results:

• ECMO gained worldwide acceptance due to its demonstrated effectiveness in hypoxemic emergencies during the H1N1 pandemic.
• Current indications for veno-venous ECMO include support for lung transplantation, COPD exacerbations, and acute respiratory distress syndrome (ARDS), potentially without mechanical ventilation.
• Despite its benefits, ECMO is associated with significant risks, notably brain hemorrhage.

Conclusions:

• ECMO is a valuable life-saving technique with expanded indications for respiratory support.
• Continued vigilance regarding ECMO-related complications, particularly neurological events, is crucial for patient safety.
