Overview

Prospective observational study investigates diaphragm ultrasonography's role in predicting weaning failure in mechanical ventilated patients, suggesting its potential utility.

Key Points

  • Right diaphragm excursion significantly predicts weaning success with a cutoff value > 7.3 mm.
  • Among 105 patients studied, the overall weaning failure rate was 14.29%, with higher rates in thoracic surgery patients.
  • Diaphragm thickness did not significantly differ between success and failure groups, emphasizing the importance of diaphragm excursion.
  • Results show specific sensitivity at 76.92% and specificity at 69.23% for predicting weaning outcomes, indicating screening potential.
