Comparing Non-Invasive Ventilation with High-Flow Nasal Oxygen to Treat Breathing Failure After Extubation in Intensive Care Units

What this Trial Is About

Researchers are investigating the best noninvasive respiratory support method for patients in intensive care units ICUs who develop respiratory failure after planned removal of their breathing tube extubation. This condition affects about 20% of ICU patients, and many require reintubation, which is linked to high mortality rates. The study aims to compare whether alternating non-invasive ventilation NIV with high-flow nasal oxygen reduces death rates compared to high-flow nasal oxygen alone in these patients. The trial is a multicenter, randomized, controlled study where patients with post-extubation respiratory failure are assigned to one of two groups. One group receives continuous high-flow nasal oxygen treatment for 48 hours, while the other group receives NIV alternating with high-flow nasal oxygen during the same period. NIV involves pressure-support breathing with specific settings to help patients breathe, and the study ensures balance in patient groups based on carbon dioxide levels in the blood. Participants will be closely monitored with assessments including timing of death, reintubation events, days without ventilator use, length of ICU and hospital stay, and mortality at different time points up to 90 days. The main outcome measured is death rate 28 days after respiratory failure onset. The study includes clinical evaluations and blood gas tests to guide treatments and decisions. Participation duration includes the initial 48-hour treatment period and follow-up assessments extending to 90 days.
