Assessment of diaphragmatic excursion-time index as a predictor of successful weaning from mechanical ventilation

Abstract

Background and aim Timing is essential for real weaning from mechanical ventilation as unfavorable weaning may provoke extended cardiovascular, respiratory-pressing factor, carbon dioxide retention, and hypoxemia. The mark of the current examination was to review the accuracy of diaphragmatic excursion-time index assessed by ultrasound as a predictor of successful weaning from mechanical ventilation. Patients and methods This is a prospective cohort study. It was done in the University Hospitals during the period from October 2019 to March 2020. Results This study was done on 36 patients over 18 years of age precisely ventilated for over 48 h legible for the beginning of weaning from mechanical ventilation. After endorsement of Institutional Ethical Committee, a written informed consent was obtained from every tolerant's family member. Patients were arbitrarily assigned into two equivalent groups: group 1: successful weaning thought about when supported spontaneous breathing without invasive or noninvasive mechanical support for over 48 h following extubation and group 2: failed weaning when the patient needs reintubation, noninvasive ventilation, or required tracheostomy within 48 h after extubation. Conclusions Ultrasound-guided diaphragmatic excursion-time index measured either at the beginning of spontaneous breathing trial or before extubation was the stronger predictor of successful weaning from mechanical ventilation compared with diaphragmatic excursion, rapid shallow breathing index, and negative inspiratory pressure.
