Brief summary

The primary objective of this study is to assess gastric volume in fasted children using ultrasound before and after drinking premedication. The hypothesis is that the qualitative and quantitative assessment by gastric ultrasound in the stomach before and after drinking premedication will be the same as premedication has a small volume.

Measure	Time frame	Description
Change of Qualitative and Quantitative Gastric Assessment After Premedication	Ultrasound scan performed at baseline (before surgery) to measure gastric volume and 3 minutes after taking premedication to assess change.	Gastric volume in fasted children before and after drinking premedication. Gastric volume in pediatric patients is estimated by the model: GV= -7.8 + (3.5× RLD CSA) + (0.127) × age (months).
