Insights
Extracorporeal membrane oxygenation (ECMO) can save neonates with severe respiratory or cardiac issues. Recent data suggests ECMO is viable for premature infants, challenging older inclusion criteria.
Area of Science:
- Neonatal medicine
- Pediatric critical care
- Cardiopulmonary support
Background:
- Extracorporeal membrane oxygenation (ECMO) is crucial for neonates with life-threatening respiratory or cardiac conditions unresponsive to standard treatments.
- Historically, strict inclusion criteria (gestational age ≥34 weeks, birthweight >2 kg) were applied due to concerns about high mortality and morbidity in preterm and low birthweight infants.
Purpose of the Study:
- To evaluate the evolving role and safety of ECMO in premature neonates.
- To assess recent evidence suggesting improved outcomes in younger/smaller infants receiving ECMO.
Main Methods:
- Review of recent publications on ECMO use in neonates.
- Analysis of survival rates and morbidities, particularly intracranial hemorrhage, in premature infants (32-34 weeks gestational age).
Main Results:
- Recent studies indicate improved survival rates among neonates between 32-34 weeks gestational age undergoing ECMO.
- A decrease in intracranial hemorrhage complications has also been observed in this population.
Conclusions:
- Current ECMO inclusion criteria, based on gestational age and birthweight, may be overly restrictive.
- ECMO should be considered on an individual basis for premature neonates, with careful consideration of potential risks and benefits.
Abstract:
Extracorporeal membrane oxygenation (ECMO) is a life-saving intervention for neonates with respiratory failure or congenital cardiac disease refractory to maximal medical management. Early studies showed high rates of mortality and morbidities among preterm and low birthweight (BW) neonates, leading to widely accepted ECMO inclusion criteria of gestational age (GA) ≥34 weeks and BW >2 kg. In recent years, publications involving neonates of 32-34 weeks GA have reported improved survival and decreased intracranial hemorrhage. As such, ECMO should be considered on a case-by-case basis in premature neonates as long as the risks are understood.
