Evaluating esophageal pressure measurements in ARDS patients during breathing trials

Japanese Esophageal Pressure Sub-study of EXTubation Evaluation and Respiratory Dynamics in Acute Respiratory Distress Syndrome (EXTEND ARDS-J EP Study)

Observational Sapporo Medical University · NCT06734988

This study is testing if measuring pressure in the esophagus during breathing trials can help doctors predict if patients with ARDS on ventilators can safely be taken off the machine.

What this trial studies

This observational study focuses on patients with Acute Respiratory Distress Syndrome (ARDS) who are mechanically ventilated. It aims to assess whether changes in esophageal pressure (ΔPes) during spontaneous breathing trials can predict the success or failure of extubation. Conducted in Japanese ICUs, the study will utilize standardized Nutrivent balloons to measure esophageal pressure and analyze its correlation with extubation outcomes. The findings could enhance current weaning protocols by providing ARDS-specific data.

Who should consider this trial

Good fit: Ideal candidates are adult mechanically ventilated patients diagnosed with ARDS who are expected to require invasive mechanical ventilation for more than 48 hours.

Not a fit: Patients who have already undergone tracheostomy or have terminal conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve extubation success rates and reduce complications for ARDS patients.

How similar studies have performed: While esophageal pressure monitoring has shown promise in other studies, its specific application in ARDS patients during extubation is relatively novel.

Eligibility criteria

Inclusion Criteria:

1. Adult mechanically ventilated patients (≥ 16 years old) with esophageal pressure monitoring, expected to receive invasive mechanical ventilator for more than 48 hours
