Using Biomarkers to Predict Extubation Failure in ICU Patients

The Value of Repeated Biomarker Measurements During an SBT to Predict Extubation Failure in Mechanically Ventilated ICU Patients

Observational Erasmus Medical Center · NCT05637099

This study is testing if measuring certain biomarkers during breathing trials can help predict if ICU patients on ventilators will successfully breathe on their own after being taken off the machine.

What this trial studies

This observational study aims to evaluate the predictive value of repeated biomarker measurements during spontaneous breathing trials (SBTs) for determining the risk of extubation failure in mechanically ventilated ICU patients. The study will involve adult patients who have been on mechanical ventilation for over 48 hours and meet specific readiness-to-wean criteria. By analyzing various biomarkers, such as NT-proBNP and hsTroponin-T, the researchers hope to improve the accuracy of extubation readiness assessments. The study will be conducted across multiple centers, collecting clinically available data alongside biomarker measurements and other assessments.

Who should consider this trial

Good fit: Ideal candidates are adult ICU patients who have been mechanically ventilated for more than 48 hours and meet the criteria for readiness to wean.

Not a fit: Patients with upper airway obstruction requiring steroid treatment or those with terminal illness may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the ability to predict extubation failure, potentially reducing the need for reintubation and improving patient outcomes in the ICU.

How similar studies have performed: While the use of biomarkers in this context is not extensively studied, the approach has shown promise in related areas of critical care.
