Sedated Auditory Brainstem Response
Evaluates hearing function, by measuring the natural electricity given off by the brain. This test is like a hearing test and looks mainly at the auditory nerve. During this test the patient does not have to do anything but relax. This is the same test that is used for the newborn hearing screenings. Sedation is used with children on whom we cannot obtain an ABR due to movement. The child is given a dose of Chloral Hydrate, based on their weight. While the child is sedated pulse rate, breathing and blood pressure are monitored. To obtain results small sticker electrodes are placed behind each ear and on the forehead. The electrodes do not administer any shocks; they simply pick up the natural electricity given off by the brain as the signal travels through the auditory system.
