The Effect of Quantitative EEG Combined With Ultrasound and Sputum Volume on Predicting Weaning Failure

After successful spontaneous breathing trial, neurocritical patients undergo at least 2 hours of quantitative EEG monitoring before extubation. Additionally, bedside ultrasound assesses the thickness and variability of the diaphragm, intercostal muscles, rectus abdominis, transversus abdominis, and external oblique muscles. The sputum volume for the 24 hours prior to extubation is also recorded. Reintubation within 48 hours after extubation is defined as weaning failure.
