Comparing the Gastric Emptying Times of Underweight and Healthy-weight School-aged Children

In the recent literature, preoperative fasting times for pediatric patients are limited to one hour for clear fluids. Studies related to gastric emptying times mostly searched for normal-weight children. These studies have claimed that 3 mL/kg of clear liquid can be allowed up to 1 hour before surgery. There is a lack of interest in the gastric emptying time of underweight pediatric patients during the preoperative period. Recent studies suggest that underweight children may experience rapid gastric emptying. This trial compares the gastric volume and emptying time after ingesting 3 mL/kg clear fluid in underweight and normal-weight pediatric patients in the preoperative period.
