When can the hearing status of a child be found out?
Hearing screening can be done when newborns are 2-7 days old. Research shows that the false positive rate of screening within 48 hours is of little reference significance. There is basically no difference in the pass rate of primary screening between 48 and 72 hours and 72 to 96 hours. This time can not only ensure the screening pass rate but also avoid loss to follow-up, so newborns in my country The optimal time for primary hearing screening is 48 to 72 hours.The Ministry of Health stipulates that newborns can undergo hearing screening in 2-7 days. According to Mai Fei, there are two commonly used newborn hearing screening methods. One is called the otoacoustic emission method, which involves inserting small earplugs into the external auditory canal of newborns and then playing a click sound of a certain intensity and frequency. The normal hearing organ (cochlea) can produce an echo to this sound, which can be captured and recorded by the receiver in the earplug, and analyzed and judged by the microcomputer in the instrument. As long as the child is quiet, the entire examination process can be completed within 1-2 minutes. Another method is automatic brainstem auditory evoked potential detection. The basic method is to place multiple small electrodes on the child's head and neck, play a specially designed click sound through the earplugs, and then use a computer to record the retrocochlear The potential changes (response to sound) in the auditory pathway (brainstem and adjacent areas) are analyzed by computer to draw conclusions. The former is more commonly used.
If the hearing loss is mild to moderate, a second hearing diagnosis needs to be done 6 months after birth. If you are still deaf, you need to take timely hearing aid measures, such as wearing bone conduction Hearing Aids. If severe or extremely severe deafness is found during the first hearing diagnosis, the second hearing diagnosis needs to be carried out 4 months after birth.
More than 30,000 newborns in my country suffer from congenital deafness every year. The most important significance of hearing screening for newborn babies is to detect it as early as possible For children with hearing impairment, early intervention is provided to these children to improve their hearing and language development abilities as much as possible.
