Effect of low tidal volume and prone positioning in patients with severe lung injury

Physiological Effect of Prone Position in Patients With Ultra-low Tidal Volume Ventilation

Observational Southeast University, China · NCT06215209

This study is testing if using very low tidal volume ventilation and having patients lie on their stomach can help adults with severe lung injury breathe better and recover faster while on a special breathing machine.

What this trial studies

This observational study investigates the effects of using ultra-low tidal volume ventilation in patients with acute respiratory distress syndrome (ARDS) who are supported by venovenous extracorporeal membrane oxygenation (VV-ECMO). The study aims to determine if adjusting tidal volume to less than 6 ml/kg can reduce ventilator-induced lung injury and improve clinical outcomes. Additionally, the study evaluates the impact of prone positioning on ventilation-perfusion matching and hemodynamics in these patients. The research focuses on adult patients undergoing invasive mechanical ventilation for less than 48 hours.

Who should consider this trial

Good fit: Ideal candidates are adults undergoing invasive mechanical ventilation and supported by VV-ECMO for less than 48 hours.

Not a fit: Patients younger than 18 years old or those with contraindications for prone position ventilation may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved outcomes and reduced lung injury in patients with severe ARDS.

How similar studies have performed: Other studies have shown promising results with low tidal volume strategies and prone positioning in ARDS, suggesting potential for success in this approach.
