Strategy of Ultra-Protective Lung Ventilation With Extracorporeal CO2 Removal for New-Onset Moderate ARDS: A Prospective Multicenter Randomized Clinical Trial

NA · University of Bologna · NCT04903262

What this trial studies

This clinical trial investigates the use of ultra-protective lung ventilation combined with extracorporeal CO2 removal in patients suffering from moderate Acute Respiratory Distress Syndrome (ARDS). The approach aims to minimize ventilator-induced lung injury (VILI) while ensuring adequate gas exchange in patients who are on invasive mechanical ventilation. By applying this innovative ventilation strategy, the study seeks to improve patient outcomes and reduce mortality associated with ARDS. The trial will include patients who meet specific criteria related to their respiratory condition and mechanical ventilation status.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who are on invasive mechanical ventilation for no more than 96 hours and meet specific clinical criteria for moderate ARDS.

Not a fit: Patients with severe COPD, chronic respiratory insufficiency requiring home ventilation, or those expected to need mechanical ventilation for less than 48 hours may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce mortality rates and improve recovery outcomes for patients with moderate ARDS.

How similar studies have performed: While the use of protective ventilation strategies has been established, the combination with extracorporeal CO2 removal is a novel approach that has not been extensively tested in this specific context.
