Implication

Randomized trial shows diaphragmatic ultrasonography improves weaning failure prediction in mechanically ventilated patients, indicating superior accuracy over standard breathing indices.

Key Points

To compare the diagnostic accuracy of the traditional rapid shallow breathing index against a novel diaphragmatic rapid shallow breathing index for predicting weaning failure.
Assessed 51 ready-to-wean patients mechanically ventilated for more than 48 hours during a T-tube spontaneous breathing trial (ClinicalTrials.gov NCT02696018).
Measured right hemidiaphragm displacement using M-mode ultrasonography alongside standard respiratory rate and tidal volume to calculate both indices simultaneously.
Overall, 34 patients (66%) successfully weaned from mechanical ventilation, whereas 17 patients (34%) failed the weaning attempt.
The diaphragmatic rapid shallow breathing index demonstrated significantly higher predictive accuracy than the traditional index, with area under the ROC curve values of 0.89 versus 0.72, respectively (P = 0.006).
