Ultrasound Guided Esophageal Pressure

The Effect of Real Time Ultrasound Guided Esophageal Pressure on Preventing Gastric Insufflation in Infants and Children: an Exploratory Study

The investigator aimed to evaluate the effect of ultrasound guided esophageal pressure on the incidence of gastric insufflation during anesthetic induction in infants and small children undergoing general anesthesia.
