COVID-19 Guidelines for All Procedures

All patients, families and visitors are required to wear a mask covering nose and mouth at all times at Lurie Children’s facilities.

If you have any questions, please call 312.227.3010. 

How to Prepare for an EEG

The night before the EEG, wash your child’s hair with shampoo.

Do not apply conditioner or other hair products and please remove any braids or hair extensions. The technologist must be able to apply the electrodes directly on your child’s scalp.

We do not sedate children for this test because sedative drugs affect the brain activity. We recommend sleep deprivation to facilitate sleep and to increase the likelihood of seeing EEG abnormalities relevant to seizure disorders. The night before the test, please ensure your child only sleeps for 4 hours or less. For example, the child can sleep only from midnight until 4 a.m. After that time, the child must be kept awake. This is extremely important in order to guarantee an optimal EEG recording. The lack of sleep puts stress on the individual’s nervous system, allowing the abnormalities to be recorded. 

Other important notes: 

• Patient may eat and drink before exam, however no caffeinated beverages.
• Take your medications as prescribed.
• Bring any rescue medications to the appointment.
• Bring Bipap or C-pap if used.
• One family member may accompany the patient in to the exam room.

How to Prepare for an Evoked Potential

The night before the Evoked Potential, wash your child’s hair with shampoo.

Do not apply conditioner or other hair products and please remove any braids or hair extensions. The technologist must be able to apply the electrodes directly on your child’s scalp.

Other important notes: 

• Patient may eat and drink before exam.
• Take your medications as prescribed.
• A neurodiagnostic technologist will call with specific instructions based on your child’s age and type of Evoked Potential being performed.
• One family member may accompany the patient in to the exam room.

How to Prepare for an EMG/NCS

Do not put any lotions or creams the day of the procedure.

For an EMG/NCS exam the child must wear long sleeve shirts, long pants and socks to keep limbs warm prior to testing. It recommended to bring a pair of gym shorts to change into for the exam.

Other important notes:

• Patient may eat and drink before exam.
• Take your medications as prescribed.
• If your child has a pacemaker or vagal nerve stimulator, please notify the doctor upon arrival.
