Ventilation Liberation Practices Among 380 International PICUs

Area of Science:

• Critical Care Medicine
• Pediatric Pulmonology
• Healthcare Quality Improvement

Background:

• Ventilator liberation protocols are crucial for optimizing patient outcomes in pediatric intensive care units (PICUs).
• International adoption and standardization of these protocols remain largely uncharacterized.

Purpose of the Study:

• To assess the global prevalence of ventilator liberation protocol use in PICUs.
• To identify common elements within these protocols.
• To estimate international extubation failure rates and the utilization of postextubation respiratory support.

Main Methods:

• An international, cross-sectional study involving nontrainee pediatric critical care physicians.
• Data collection was conducted via an electronic survey distributed to physicians across 47 countries.
• The survey focused on ventilator liberation practices, protocol elements, and extubation outcomes.

Main Results:

• Protocols for spontaneous breathing trial (SBT) practice and endotracheal tube cuff management were the most common, used by over 50% of PICUs.
• Significant international variation was observed in most surveyed practices.
• The median estimated international extubation failure rate was 5%, with low reported use of planned postextubation noninvasive respiratory support.

Conclusions:

• There is high variability and generally low implementation of ventilator liberation protocols in international PICUs.
• Further research is needed to identify factors influencing clinical outcomes.
• Standardization of pediatric ventilation liberation practices globally presents a significant opportunity for improvement.
