Patterns of Multiple Organ Dysfunction in Children on Extracorporeal Membrane Oxygenation Support

Area of Science:

• Pediatric critical care medicine
• Cardiopulmonary support
• Organ dysfunction research

Background:

• Extracorporeal membrane oxygenation (ECMO) is a life-support technology for critically ill children.
• Understanding organ dysfunction patterns during ECMO is crucial for improving survival rates.
• Limited data exists on the temporal evolution of multiple organ dysfunction (OD) in pediatric ECMO patients.

Purpose of the Study:

• To characterize multiple organ dysfunction (OD) patterns in children receiving ECMO.
• To investigate the association between OD patterns and in-hospital mortality.
• To identify critical time points for intervention in pediatric ECMO patients.

Main Methods:

• Retrospective analysis of 317 children on ECMO support (2011-2024).
• Assessment of organ dysfunction using Pediatric Organ Dysfunction Information Update Mandate (PODIUM) criteria, Pediatric Sequential Organ Failure Assessment (pSOFA), and Pediatric Logistic Organ Dysfunction-2 (PELOD-2) scores at 24-hour intervals.
• Statistical analysis including multiple logistic regression and survival analyses.

Main Results:

• No significant difference in concurrent ODs between survivors and non-survivors before ECMO cannulation.
• Non-survivors developed significantly more ODs starting from the day of cannulation (median 7) compared to survivors (median 6).
• pSOFA and PELOD-2 scores also showed significant differences between survivors and non-survivors, mirroring the OD pattern.

Conclusions:

• Multiple organ dysfunction accumulation begins shortly after ECMO cannulation in non-survivors.
• Identifying intervenable risk factors before and during cannulation may alter OD trajectory and reduce mortality.
• Temporal analysis of OD provides insights into ECMO patient management and prognosis.
