Study Comparing Two Noninvasive Respiratory Support Methods After Breathing Tube Removal in Severely Obese Adults

What this Trial Is About

Around 20% of severely obese patients who are taken off a breathing tube and ventilator need it re-applied, which is linked to poor outcomes like pneumonia, longer hospital stays, and death. This study evaluates whether using noninvasive breathing support right after removing the breathing tube can lower the chance of needing it again. The trial focuses on patients with obesity-related respiratory risks and aims to reduce respiratory failure after extubation. Participants are randomly assigned to one of two groups. One group receives noninvasive ventilation NIV alternating with high flow nasal cannula HFNC for a total of 24 hours after extubation, with 16 hours of NIV and 8 hours of HFNC. The other group receives only HFNC for 24 hours after extubation. This design compares the effects of combined NIV and HFNC versus HFNC alone on reducing treatment failure. During the study, participants are monitored for the first 72 hours after planned extubation to see if they need rescue respiratory support due to acute respiratory failure. The main outcome is treatment failure within this period. Reintubation rates are also assessed at 7 days. Researchers will evaluate patient respiratory status, treatment adherence, and complications to determine the best approach for preventing respiratory failure. The study lasts from enrollment through these follow-up periods.
