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.

Inclusion Criteria: * Children aged 0 to 35 months * Scheduled for elective surgery under general anesthesia * Planned airway management with a laryngeal mask airway * Ability to perform intraoperative ultrasonographic subglottic airway measurements * Written informed consent obtained from a parent or legal guardian Exclusion Criteria: * Known congenital or acquired airway anomalies * Craniofacial anomalies * Emergency surgical procedures * Planned tracheal intubation instead of laryngeal mask airway * Inability to obtain adequate ultrasonographic subglottic airway measurements

Outcomes

Primary Outcomes

Perioperative respiratory adverse events (PRAE)

The occurrence of clinically significant perioperative respiratory adverse events, defined as moderate to severe stridor and/or laryngospasm requiring clinical intervention, including positive pressur

Time frame: immediately after the surgery

Secondary Outcomes

Ultrasonographic subglottic airway dimensions and area

Subglottic airway mediolateral and anteroposterior diameters and the calculated subglottic cross-sectional area measured using ultrasonography at predefined intraoperative time points (T0, T1, and T2). Changes in subglottic airway area between time points (T0-T1, T1-T2, and T0-T2) will also be evaluated.

Time frame: During surgery
