Extra-Corporeal Membrane Oxygenation for Neonatal Respiratory Support.

Area of Science:

• Neonatal Medicine
• Cardiopulmonary Support
• Pediatric Critical Care

Background:

• Extra-Corporeal Membrane Oxygenation (ECMO) is a vital life support technology for neonates with severe respiratory failure.
• The study reviews a large, single-center experience with neonatal ECMO over three decades.

Purpose of the Study:

• To evaluate the outcomes and complications of neonatal respiratory ECMO.
• To compare the center's results with the Extracorporeal Life Support Organization (ELSO) Registry.

Main Methods:

• Retrospective review of 764 neonates undergoing respiratory ECMO between 1989 and 2018.
• Analysis of cannulation strategies (Veno-Venous vs. Veno-Arterial) and associated outcomes.
• Assessment of major complications and survival rates based on diagnosis and cannulation type.

Main Results:

• Overall survival to hospital discharge was 84% (640/764 neonates).
• Survival rates varied by diagnosis, with meconium aspiration (98%) and pneumonia (86%) showing higher survival than congenital diaphragmatic hernia (66%) and sepsis (59%).
• Survival with Veno-Venous (86%) and Veno-Arterial (80%) cannulation exceeded ELSO Registry rates (77% and 63%, respectively).
• Major complications included cerebral infarction/hemorrhage (4.7%) and renal replacement therapy (17.6%).
• Intracerebral hemorrhage rates decreased after circuit modification.

Conclusions:

• Neonatal ECMO outcomes in this large case series were excellent, surpassing ELSO Registry benchmarks.
• High-volume ECMO services are associated with improved survival and reduced complication rates.
• The similar survival rates for Veno-Arterial and Veno-Venous cannulation may reflect adaptations due to cannula availability.
