Stridor Clinical Trial
Official title:
Predicting Post Extubation Stridor in Patients With Intermaxillary Fixation
Endotracheal intubation can induce laryngotracheal injury which results in narrowing of the airway due to edema of the glottis. This can increase the risk of development of post-extubation stridor (PES)
Ultrasound (US) is a useful and non-invasive tool for the evaluation of vocal cords and laryngeal morphology in intubated patients. The laryngeal air-column width (LACW), Laryngeal air column width difference (LACWD), and laryngeal air-column width ratio (LACWR) measured by ultrasound can potentially identify patients at risk of post-extubation stridor, in whom caution should be taken after extubation. The cuff-leak test can predict successful extubation through using the difference between the expired tidal volume with the cuff inflated and with the cuff deflated; the higher the leak, the lower the likelihood that post-extubation stridor will occur. ;
