Evaluating diaphragm performance during weaning from mechanical ventilation

Evaluation of the Diaphragm Tissue Doppler Parameters in Predicting Weaning From Mechanical Ventilation Outcome

Observational Mongi Slim Hospital · NCT06203353

This study looks at how well the diaphragm works in adult ICU patients who are trying to stop using a breathing machine to see if it can help predict their success in weaning off the ventilator.

What this trial studies

This observational study involves adult ICU patients who have been on invasive mechanical ventilation for at least 48 hours. It focuses on assessing diaphragm function through ultrasound before conducting a T tube spontaneous breathing test during the weaning process. Key parameters such as diaphragm excursion, thickening fraction, and contraction velocities will be measured to predict weaning outcomes. Patients will be categorized based on their success in weaning from mechanical ventilation, allowing for a comparison of diaphragm ultrasound patterns between groups.

Who should consider this trial

Good fit: Ideal candidates are adult ICU patients requiring invasive mechanical ventilation for more than 48 hours with a Glasgow Coma Scale score greater than 13.

Not a fit: Patients who may not benefit include those with chronic respiratory failure or those requiring reintubation for reasons unrelated to respiratory issues.

Why it matters

Potential benefit: If successful, this study could improve the understanding of diaphragm function and enhance weaning protocols from mechanical ventilation.

How similar studies have performed: While diaphragm ultrasound has been explored in other contexts, this specific approach to predicting weaning outcomes is relatively novel.
