Brief summary

Aspiration of gastric contents can be a serious anesthetic related complication. Gastric antral sonography prior to anesthesia may have a role in identifying pediatric patients at risk of aspiration. The investigator examined the relationship between sonographic antral area and endoscopically suctioned gastric volumes infants.

Interventions

DIAGNOSTIC_TESTGUS

gastric volume estimation using gastric ultrasound was performed immediately after anesthetic induction, and after aspirating the residual gastric contents using nasogastric tube
