How is the test done?
• A child may be sleeping or sedated. • Electrodes on sticky pads are placed in or behind the child’s ears and on the head. The electrodes record how the brain responds to different sounds. These sounds travel through earphones or headphones, which are placed inside or over the child’s ears. • The test takes 30-60 minutes.
The test is performed in an x-ray room so x-rays can be used to record the results. If there is any possibility that you may be pregnant, tell your doctor. You will be asked to put on a hospital gown and to remove eyeglasses or contact lenses. Dentures will remain in place during the procedure. A small intravenous needle (IV) will be placed in your hand or arm. Medications will be given through the IV to help you relax and make swallowing easier. To numb your throat and reduce gagging, a local anaesthetic may be sprayed into your throat. You will be asked to lie flat on your stomach. The doctor will help you swallow the endoscope. A plastic guard will be placed to protect your teeth and the endoscope. X-ray dye (iodine) will be injected through a small plastic tube (cannula) which has been passed through the endoscope and into your ducts. X-rays will be taken to see how the dye flows through the ducts. The test takes from 15 to 60 minutes.
