Contemporary Trends in Pediatric Extubation Failure and Noninvasive Respiratory Support Use.

Area of Science:

• Pediatric Critical Care Medicine
• Respiratory Support Strategies
• Mechanical Ventilation Outcomes

Background:

• Prolonged mechanical ventilation in children increases morbidity and mortality risks.
• Timely extubation requires balancing extubation failure (EF) against prolonged non-invasive support.
• Understanding trends in EF and respiratory support is crucial for pediatric critical care.

Purpose of the Study:

• To investigate changes in EF risk factors, rates, and post-extubation non-invasive respiratory support practices from 2013-2022.
• To evaluate patient-centered outcomes associated with these changes.
• To identify trends in pediatric extubation management over a decade.

Main Methods:

• Retrospective cross-sectional study of 132,712 pediatric encounters (age < 19) requiring invasive mechanical ventilation ≥ 24 hours.
• Data analyzed from the Virtual Pediatric Intensive Care, LLC quality improvement database (2013-2022).
• Logistic regression used to identify EF risk factors and assess outcome associations.

Main Results:

• Overall EF rate was 8.5%; post-extubation non-invasive support use nearly doubled (20.9% to 39.9%).
• EF rates slightly decreased (≤7 days: 12.3% to 11.0%).
• Younger age, specific diagnoses (renal, respiratory, cardiac), and longer pre-extubation ventilation were associated with increased EF odds. EF correlated with longer ICU and hospital stays but not mortality.

Conclusions:

• Post-extubation non-invasive support has significantly increased, correlating with a modest reduction in EF.
• High-risk pediatric populations may benefit, but potential overuse in low-risk groups warrants consideration.
• Extubation failure is associated with significant morbidity but not increased mortality in pediatric patients.
