Feasibility of 1 Hour Clear Fluid Fasting Prior to Paediatric GA

The study is aim to investigate the appropriate fasting time for clear fluid in paediatric patients who plan for elective minor surgery. This is a randomize control trial, which patient will be selected randomly to fast for clear fluid for 1 hour or 2 hours. It is important to determine the gastric residual volume for paediatric age group prior to elective minor surgery in order to determine whether the difference between 1 hour fasting and 2 hour fasting for clear fluid is significant.
