 Why
is sedation administered?
During an EEG test, which can last up to one and half-hours, children are required
to remain very still. This is generally not possible for children 5 years and
under. Therefore, these children are usually given medication called chloral
hydrate which produces quiet, deep sleep.
Following administration of chloral hydrate, drowsiness occurs within 10 to
15 minutes and sleep usually occurs within 30 to 60 minutes. Most children will
awaken fully within 2 hours but in some cases sleep can last 4 to 8 hours.
Before the parent/guardian administers chloral hydrate, they must notify the
technician if the child has a history of ADENOIDAL HYPERTROPHY or OBSTRUCTIVE
SLEEP APNEA.
Since stomach irritation and vomiting may occur following administration, it
is best to take chloral hydrate with a full glass of fluid.
Most children will awaken before they leave the hospital. However, in some
instances, children (especially the very young) will remain sleeping for up
to 8 hours.
You should check your child frequently – at least every 30 minutes if
they remain sleeping after leaving the hospital until they are fully awake.
If the child is still sleeping 3 hours after administration of the medication,
you are to wake them up.
Contact your physician, or if they are not available, go to the Emergency Room,
if any of the following occurs:
- Their breathing is very slow and/or shallow.
- Their breathing sounds obstructed.
- If you are unable to awaken your child after 3 hours.
