Brief summary

Background: Gastric ultrasound is an effective, non-invasive method to assess the nature and volume of gastric content in the pediatric population. A recent consensus of the Association of Pediatric Anesthesiologists of Great Britain and Ireland, the European Society of Pediatric Anesthesiology, and the French Anesthesia and Resuscitation Society recommend shortening the fast for clear fluids in children to one hour. However, studies showing that one hour of fasting is safe in the pediatric population are still scarce. This study aims to verify by ultrasound evaluation if one hour of fasting for clear liquids is sufficient to have an empty stomach before anesthetic induction. Methodology: Patients between 11 months and 16 years of age scheduled for elective outpatient surgery were included. A qualitative and quantitative ultrasound evaluation was performed by calculating the cross-sectional area of the gastric antrum, one hour after ingesting a volume of 3 mL/kg of a non-carbonated sports drink, before anesthetic induction.

Interventions

All patients were scheduled 2 hours before the surgical procedure. The patients were questioned about the exclusion criteria. Data on gender, age and weight were collected from the clinical history by the anesthesiologist and recorded in the data collection instrument. 1 hour before the assigned time for surgery, they were asked to consume 3 mL/kg of body weight of a non-carbonated sports drink (140 calories, Total fat 0%, Sodium 11%, potassium 2%, carbohydrates 12%, protein 0%).

Drink ingestion was supervised by a nurse and consumed in less than 5 minutes. All patients were instructed to adhere to the preoperative fasting guidelines of the American Society of Anesthesiology (6 hours for solid foods, 4 hours for breast milk, and 2 hours for clear liquids). 1 hour after ingestion of the drink, measurements of gastric contents were obtained by ultrasound before anesthetic induction. All patients had perioperative follow-up until discharge
