Premedication Gastric Ultrasound

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.
