Pediatric ECMO Outcomes in Children With Severe Infections: Does Infectious Source Matter?

Area of Science:

• Pediatric critical care medicine
• Infectious diseases
• Cardiopulmonary support

Background:

• Extracorporeal Membrane Oxygenation (ECMO) improves survival for pediatric patients with cardiopulmonary failure due to infection.
• However, the impact of specific infectious etiologies on ECMO outcomes remains unclear.
• This study investigates how culture data from infections influences outcomes in children receiving ECMO.

Purpose of the Study:

• To compare ECMO outcomes in pediatric patients with sepsis and severe acute lung injury based on infectious etiology.
• To analyze the impact of positive culture data on mortality during and after ECMO treatment.

Main Methods:

• Retrospective review of pediatric patients (<18 years) managed with ECMO for severe infections (2013-2022).
• Analysis of respiratory and blood culture data at the time of ECMO cannulation.
• Comparison of mortality rates using univariate and multivariate regression models.

Main Results:

• Overall mortality on ECMO was 36%, and mortality at discharge was 51%.
• Patients with positive blood and respiratory cultures at cannulation had a 7.65-fold increased hazard for mortality on ECMO (p=0.004).
• Multiple viral infections (e.g., RSV, COVID) were associated with higher ECMO mortality, while polymicrobial bacterial pneumonia showed no significant difference.

Conclusions:

• The infectious source significantly impacts ECMO outcomes in pediatric patients with cardiopulmonary failure.
• Identifying the specific pathogen is crucial for prognostication and family counseling before ECMO initiation.
