Dietary instructions should be as follows:


Clear liquid should be stopped up to 3 hours
before the procedure for children aged 6
months and older No milk or solids for 6 hours
for children aged 6 months to 3 years and for
6 to 8 hours for children 3 years and older.
The reasons for these recommendations are:
Vomiting during or immediately after a
sedative procedure is a potential complication
that can result in aspiration of stomach
contents leading to laryngospasm or severe
airway obstruction or aspiration pneumonia. It
also creates unfavorable disruption of the
office routine. Secondly, the drug uptake is
maximized when the stomach is empty as
most of the conscious sedation agents are
administered.
