Gastric ultrasound is a non-invasive bedside tool with high sensitivity and specificity for determining the nature and amount of gastric content. In pediatric cases, maintaining a gastric volume below 1.25 mL\u002Fkg is associated with a lower risk of perioperative aspiration.\n\nAlthough supraglottic airway devices (SADs) are commonly used as alternatives to endotracheal tubes, concerns regarding the potential for gastric insufflation and subsequent aspiration persist. Second-generation SADs were specifically designed with gastric drainage channels to mitigate the risk of regurgitation compared to first-generation devices.\n\nThe primary objective of this study is to determine whether there is a difference in gastric volumes, as measured by ultrasound, among three groups of pediatric patients: those managed with endotracheal tubes, first-generation SADs, and second-generation SADs. By comparing these measurements post-ventilation, the investigators aim to evaluate the impact of the airway device choice on gastric volume under clinical conditions.",[65,66,67,68,69,70],"Gastric Ultrasonography","Supraglottic Airways","Supraglottic Airway Use in Children","Gastric Volume","Gastric Insufflation","Airway Complications",[72,73],"gastric ultrasonography","airway management","NOT_YET_RECRUITING","2026-06-04",{"date":77,"type":78},"2026-06-08","ACTUAL",{"date":80,"type":60},"2026-06-15",{"date":82,"type":60},"2026-09",{"name":5,"class":6},1]
