ABRs are done when: Preparing for the test depends on your child's age.
Older kids might get sedation (medicine given to make a child relaxed, calm, or sleepy) for an ABR.
An auditory brainstem response (ABR) test is a safe and painless test to see how the hearing nerves and brain respond to sounds.
It gives health care providers information about possible hearing loss.
Each year, millions of infants and children require sedation and pain control for medical procedures.
If your child needs sedation, discuss the risks and benefits with your health care provider or sedation team before the test.
If so, you will get instructions about fasting before the test and what to do at home after the test.
If your child is: An audiologist places small earphones in the child's ears and soft electrodes (small sensor stickers) near the ears and on the forehead.
Symptomatic measures, such as increasing fluids, making sure children get enough rest and reducing the spread of the virus (including regular hand washing) should be practiced.
For children requiring antihistamines for allergies, a non-sedating antihistamine such as loratadine or cetirizine is preferred.
Sedating antihistamines have the ability to cross the blood-brain barrier, the ability to bind to non-histamine receptors and have less selectivity for peripheral or central H1-receptors.
