Ultrasound assessment for regional ventilation during weaning from different modes of ventilation.

Background: As a consequence of respiratory failure, the majority of patients in intensive care units (ICUs) need mechanical ventilation (MV). Prompt weaning from MV is crucial to prevent undesired side effects, such as ventilator-associated pneumonia and ventilator-induced diaphragm atrophy. Advances in ultrasonography have enabled the Monitoring lung aeration all through the weaning process, offering insights into factors contributing to weaning failure. This study was conducted to assess Lung aeration and calculate the lung ultrasound score (LUS) during weaning from different modes of mechanical ventilation in ICU patients and to correlate the Ultrasound findings of lung aeration with patient's prognosis. Methods: We conducted a descriptive prospective comparative study in military hospitals, involving 52 mechanically-ventilated ICU patients over a 9-month period. We assessed patient outcomes related to extubation and survival and compared our findings with prior research. Results: Out of the studied patients, 50% successful extubation, and 55.8% survived. This aligns with previous studies reporting similar outcomes. Increased lung ultrasound scores (LUS) were observed in patients with unsuccessful extubation and mortality. Conclusion: This study highlights the utility of ultrasound in assessing lung aeration during weaning from different ventilation modes. It emphasizes the significance of LUS in predicting extubation failure and patient survival. Our findings suggest that LUS, particularly in the lateral and posterior inferior regions, can be a valuable tool in weaning protocols.
