Prediction of Extubation Failure: A Multicenter Prospective Observational Study

March 20, 2026 updated by: Duan jun, Chongqing Medical University

The First Affiliated Hospital of Chongqing Medical University

The investigators intend to collect several variables to predict extubation failure among patients who successfully complete a spontaneous breathing trial, and then develop a scale using simple bedside indicators to predict extubation failure.

Detailed Description

Mechanically ventilated patients who successfully completed a spontaneous breathing trial and prepared for extubation are eligible to enroll in this study. The vital signs, arterial blood gas tests, cough strength, cuff leak test, use of noninvasive ventilation et al. are collected. Patients are followed up to postextubation 28-day or discharge. Extubation failure is defined as reintubatin or death within postextubation 7 days. First, we will analyze the data to predict extubation failure. Then, we will combine several easily obtained variables to develop and validate a scale to predict extubation failure. Finally, we explore the predictive power of extubation failure tested by the scale and find the cutoff value to distinguish the low, moderate and high risk of extubation failure.
