Summary

Neonates on extracorporeal membrane oxygenation (ECMO) show factor deficiency and coagulation activation. Early intervention with plasma may be needed to manage coagulopathy in these critically ill infants.

Area of Science:

  • Neonatal intensive care
  • Pediatric cardiology
  • Hematology

Background:

  • Severe hypoxemia in neonates often necessitates extracorporeal membrane oxygenation (ECMO).
  • Coagulation disorders are a significant concern in neonates undergoing ECMO.
  • Understanding coagulation factor activity is crucial for managing these complex cases.

Purpose of the Study:

  • To evaluate the activity of key coagulation factors in neonates during the initial 24 hours of ECMO.
  • To assess changes in coagulation and its markers in neonates with hypoxemia supported by ECMO.

Main Methods:

  • Prospective observational study conducted in a specialized ECMO center.
  • Included ten neonates receiving ECMO for severe hypoxemia.
  • Measured coagulation factor activity, anti-thrombin III, and blood activation markers before and during the first 24 hours of ECMO.

Main Results:

  • Laboratory evidence of factor deficiency and coagulation activation was present at all measured time points.
  • ECMO initiation initially worsened coagulopathy.
  • Pre-existing factor deficiency and abnormal coagulation activation were observed in these critically ill neonates prior to ECMO.

Conclusions:

  • A proactive strategy is necessary to prevent factor deficiency and manage coagulopathy in neonates on ECMO.
  • Fresh frozen plasma may be considered for correcting factor activity.
  • The impact of such interventions on clinical outcomes requires further investigation.
