Combined Thoracic Ultrasound Using Speckle Tracking for the Prediction of Weaning Failure: a Prospective Multicenter Study

What this Trial Is About

This research aims to improve the timing for removing breathing tubes in patients who are mechanically ventilated, focusing on predicting when patients may fail to wean off ventilation. Traditional tools for predicting weaning success are not very accurate. The study evaluates a new ultrasound method called speckle tracking echocardiography, which assesses heart and lung function and may more reliably detect early heart dysfunction and elevated heart filling pressure associated with weaning failure. Participants in the study undergo speckle tracking echocardiography during their ventilator weaning trial to assess its diagnostic accuracy for predicting weaning failure. The study also looks at the combined use of conventional heart and lung ultrasound for this purpose. The trial includes patients in intensive care units who meet criteria for a ventilation weaning trial and also involves healthy volunteers for comparison. During the study, lung and heart ultrasounds are performed just before and during the weaning trial to collect data. Researchers measure how well these imaging methods predict weaning outcomes. The study monitors participants' heart and lung function using ultrasound techniques, aiming to improve understanding of weaning failure risks. Participation involves following the imaging assessments during the weaning process, with safety and outcomes tracked until extubation decisions are made.
