Air leak test in the Paediatric Intensive Care Unit (ALTIPICU): rationale and protocol for a prospective multicentre...

Area of Science:

• Pediatric Critical Care Medicine
• Respiratory Physiology
• Clinical Trial Methodology

Background:

• Upper airway obstruction (UAO) is a frequent complication following extubation in children.
• The quantitative cuff-leak test (qtCLT) is a non-invasive method to assess this risk but requires further validation in pediatric populations.
• Current methods for predicting postextubation UAO in pediatric intensive care unit (PICU) patients have limitations.

Purpose of the Study:

• To assess the predictive accuracy of the qtCLT for UAO-related respiratory distress in pediatric ICU patients.
• To identify risk factors associated with postextubation UAO and extubation failure.
• To determine if qtCLT can reliably identify children at high risk for adverse postextubation events.

Main Methods:

• A multicenter, prospective, observational study involving 900 pediatric patients (2 days to 17 years) ventilated for at least 24 hours.
• The qtCLT will be performed within one hour of planned extubation, measuring air leak with the endotracheal tube cuff deflated.
• Primary outcome: severe UAO within 48 hours post-extubation, defined by specific clinical criteria and Westley score.

Main Results:

• This section will report on the performance of the qtCLT in predicting severe UAO.
• Analysis will identify specific patient subgroups at higher risk for UAO.
• The study aims to establish the reliability of qtCLT in the PICU setting.

Conclusions:

• The study is expected to provide evidence on the utility of qtCLT for predicting postextubation UAO in children.
• Results may inform clinical practice guidelines for extubation in pediatric intensive care.
• Identifying reliable predictors like qtCLT can improve patient outcomes and resource allocation.
