ABR

we finally got a date for one, and I'm not sure if they will do it now. *sigh* we have to speak to her docs about it.

I thought she had had one before? Are they seeing if anything has changed?

Are you thinking they won't want to sedate her, because I could see how that could be concerning right now!

Dates for appt's never have good timing do they

no kidding!

no she has never had one done. Which is why we want one. but we have been talking about it for months (waiting on an appointment). they never did one cuz they didnt want to sedate her...then we felt comfortable enough sedating her, and all this happened so they told us we could reschedule it if we want..i dont really want to. but am waiting to hear back from her docs.

i think its really improtant we get one, so we know exactly what her hearing loss is without worrying if shes doing something wrong (during the other tests) and giving us wrong results.

We did it for the exact same reasons. We couldn't rely on her cognitive skills for the tests to be accurate. We were really glad that we got it done as it did provide alot of new info.

Hopefully L will be ok'd for it in the not too distant future. The sedation can be quite minimal. They were also hesitant to sedate dd too much and she woke 2 times during the test, but it didn't matter, she fell back asleep and they continued.

what does ABR stand for?

Auditory brainstem response (ABR), also known as brainstem evoked response (BSER) is an electrical signal evoked from the brainstem of a human or other mammal by the presentation of a sound such as a click.
Auditory brainstem response audiometry or Brainstem evoked response audiometry (BERA), is a screening test to monitor for hearing loss or deafness, especially notable for its use with newborn infants. It is a method employed to assess the functions of the ears, cranial nerves, and various brain functions of the lower part of the auditory system, prior to the child developing to the point of describing a possible hearing problem. The procedure is to generate a brief click or tone pip from an earphone or headphone and measuring the elicited neuronal action potentials by surface electrodes, typically placed at the vertex of the scalp and ear lobes.[1] The potential of the signal in microvoltage is averaged and charted against the time (millisecond), similarly to an electroencephalography (EEG).[1]
ABR audiometry is a safe and painless test of auditory pathway and brainstem function in response to auditory or (click) stimuli. The procedure was first described by Jewett and Williston in 1971. ABR audiometry is the most common application of auditory evoked responses. Test administration and interpretation are typically performed by an audiologist. (See reference)

thats good to know.

Curious, does she have a hearing loss?

I copied and pasted a description...

It is basically a hearing test that shows what the brain is hearing, not just the ears per se. So it can show if hearing function is diminished due to fluid or because it is permanent, etc.

What is an Auditory Brainstem Response test?

An Auditory Brainstem Response (ABR) test is a sleep EEG hearing test which shows the softest sounds your child's ears can detect at various pitches.

How is the test performed?

There will be 3 or 4 small stickers on your child's head, connected to leads going into a computer. Sounds will be presented through an earphone to each ear separately while a computer analyzes the changes in the brain wave pattern in response to sounds.
The test is not painful or uncomfortable in any way, but it is necessary for your child to be asleep in order to obtain clear recordings during the test. You will be in the room with your child during the test, and the results will be explained immediately afterward. This test may be performed sedated or unsedated, depending on the age and health of your child. “

ha you are way faster then me lol!

MrsSunshine · 06-11-2010, 02:28 PM

Sophie was diagnosed with moderate hearing loss as an infant up to about 2 years old. We now believe she has very good hearing, the ABR showed it was not permanent. Some of it would of also been because of her brain injury.
