Ultrasonographic Subglottic Airway Measurements and Postoperative Respiratory Events in Young Children
Sponsor: Bursa Sevket Yilmaz Training and Research Hospital
Summary
This study aims to better understand airway-related respiratory events that may occur in children under three years of age undergoing general anesthesia with a laryngeal mask airway (LMA). As part of the study, ultrasonographic measurements of the subglottic airway will be performed at different time points during anesthesia using a non-invasive ultrasound device. Changes in these measurements will be evaluated in relation to intervention-requiring upper-airway events occurring during anesthesia, LMA removal, or early recovery. The results may contribute to a better understanding of airway-related factors associated with respiratory events in young children undergoing anesthesia with an LMA.

Interventions
Serial subglottic airway ultrasonography
Non-invasive ultrasonographic assessment of the subglottic airway performed at predefined time points during general anesthesia. Medioloateral and anteroposterior airway dimensions were measured to evaluate serial changes in subglottic airway geometry. The ultrasonographic assessments were performed for observational study purposes and did not alter routine anesthetic or airway management.
