Background: Mechanical ventilation waning failure is a common problem, and bedside ultrasonography could be helpful in prediction of the weaning process and its results.
Aim of The Work: To ssess by means of ultrasound how diaphragmatic parameters are important in predicting weaning outcome by assessing diaphragmatic thickness, diaphragmatic mobility and variation.
Patients and Methods: This study included 62 mechanically ventilated patients who were subjected to transthoracic ultrasonography of the diaphragm throughout a spontaneous breathing experiment and had been divided into two groups: successful extubation and unsuccessful extubation.
Results: With a p-value of <0.001, a high DE after extubation was linked to extubation success. Extubation failure was linked to lower DTF before and after extubation, with a p-value of 15 had 100% sensitivity, 85.06% specificity, 70.5 PPV and 100% NPV with p-value 20.4 had 93.55% sensitivity, 93.55% specificity, 93.5% PPV, and 93.5% NPV with p-value Conclusion: Diaphragm ultrasound evaluation of DTF and DE is a simple new weaning index which can be used as a bedside technique in clinical practice and has promising predictors of weaning success or failure before and after extubation.
