Official title
Association Between Ultrasonographic Subglottic Airway Measurements and Postoperative Respiratory Adverse Events in Children Under Three Years of Age
Overview
This study aims to better understand postoperative respiratory adverse events that may occur in some children under three years of age undergoing airway management during surgery. As part of the study, ultrasonographic measurements of a portion of the upper airway will be performed during surgery using a non-invasive ultrasound device. These measurements will be evaluated in relation to perioperative respiratory outcomes. The results of this study may contribute to improved understanding of airway-related factors associated with postoperative respiratory safety in young children.
Interventions
- Other Ultrasonographic subglottic airway measurement
Non-invasive ultrasonographic measurement of the subglottic airway performed intraoperatively as part of routine clinical care. No therapeutic intervention is applied.
Primary outcome measures
- Perioperative respiratory adverse events (PRAE) [Time frame: immediately after the surgery]
Secondary outcome measures (1)
- Ultrasonographic subglottic airway dimensions and area [Time frame: During surgery]
