Lung Ultrasound Morphology Patterns Predict Weaning Outcomes

This prospective observational study aims to investigate the impact of lung ultrasound morphology patterns on treatment response and weaning outcomes in high-risk mechanically ventilated patients. The study will be conducted in the intensive care unit (ICU) and will include patients who have been on mechanical ventilation for over 24 hours, are at high risk for reintubation due to age (\>65 years) or underlying conditions (chronic heart or lung disease), and have a Lung Ultrasound Score (LUS) \>13. Patients will be stratified into two groups based on their lung ultrasound patterns: localized tissue-like patterns (TLP) and diffuse B-lines (DBP). Daily lung ultrasound examinations will be performed, and patients will receive targeted clinical interventions based on their ultrasound findings, such as lung recruitment maneuvers, positive end-expiratory pressure (PEEP) ventilation, prone positioning, pleural effusion drainage, antibiotics for pneumonia, and strategies for achieving negative fluid balance. The primary outcome will be the change in Lung Recruitment Score (LRS) between the TLP and DBP groups, which assesses lung recruitment efficiency. Secondary outcomes will include the rate of weaning failure, duration of mechanical ventilation, ICU mortality, total ICU stay duration, and PaO2/FiO2 ratio before and after the spontaneous breathing trial (SBT). This study aims to provide insights into the utility of lung ultrasound morphology patterns in guiding clinical intervent…
