Newborns should be screened for hearing for 7 thousand years

As the saying goes, “Ten deaf and nine dumb”.

According to statistics, the incidence of hearing impairment in normal newborns is one-thousandth to three-thousandths, and the newborns in the intensive care unit can have an incidence of hearing impairment as high as two to four percent.
How to prevent hearing-impaired children from hearing dumb?

Can hearing impaired children recover their hearing?

March 3 is the eleventh national “Earl’s Day” publicity and education event.

  ”The hearing screening of newborns is an important tool for early detection of deafness.

“Mai Fei said,” Before, because children who were too young could not express, the children were not easy to find in the pupa period. They only discovered when they were two or three years old that they had missed the best treatment period.

Nowadays, the technologies and equipment for newborn hearing screening are constantly being updated. For example, hearing screening can be used to detect whether the hearing is normal 48 hours after birth.

“Internationally, the three-early principle has been implemented for children with hearing loss: early detection, early diagnosis, and early intervention.

Starting from June 1 last year, the “Administrative Measures for the Screening of Newborn Diseases” submitted by the Ministry of Health was officially implemented throughout the country, which stipulates that medical institutions with obstetrics or pediatrics in the diagnosis and treatment subjects have adopted the “Technical Specifications for the Screening of Newborn Diseases”》》 Newborn disease screening should be conducted. If the condition is not met, the guardian should be informed to go to a qualified medical institution for blood screening and hearing screening for newborn disease screening.

It can be seen that newborn hearing screening has become one of the important contents.

  Parents can also find that their child’s hearing is abnormal. In the clinic, they often encounter some regrets that cause headaches and pains for doctors. Many parents ca n’t speak because their children are two or three years old, or their articulate is not clear when they are five or six years old.Hands and feet often delay the best time for diagnosis and treatment.

Mai Fei said that although from a professional perspective, newborn hearing screening requires certain technical standards and equipment, but for ordinary parents, in addition to taking their children to the hospital for newborn hearing screening, it can also be found through careful observation.Whether the child’s hearing is abnormal—the child can hear sounds right after birth. Although they do not trigger an active response, they can generate subconscious reflex activities under the stimulation of sound to avoid avoiding his vision in him.Hitting the object near the ear produces sound, he will make blinking, physical discomfort and other actions; after four months, the child has the ability to actively find the sound source, after hearing the strong sound stimulation, he will use his eyes or turn his head to find.

Children around one year old can understand simple words and make simple actions according to language commands; they can understand simple language when they are two years old.

If a child’s response is found to be inconsistent at this age, it should be questioned whether the child has a hearing impairment.

  ”Once the child’s hearing abnormality is found, he should be diagnosed and treated as early as possible.

“Newborns can be screened for hearing at 2-7 days, and the Ministry of Health has stipulated that they can be screened for hearing at 2-7 days.

Mai Fei introduced that there are two commonly used newborn hearing screening methods. One is called otoacoustic emission method, which inserts a small earplug into the newborn’s external auditory meatus and then plays a click with a certain intensity and frequency.

A normal hearing organ (cochlea) can echo this sound, otherwise it can be captured and recorded by a receiver in the earplug, analyzed and judged by the microcomputer in the instrument.

As long as the child is quiet, the entire examination can be completed in 1-2 minutes.

Another method is automatic brainstem auditory evoked potential detection. The basic method is: insert multiple small electrodes into the child’s head and correct it, and play a specially designed click through the earplugs, and then use a computer to record the cochlear auditory pathway(Brain stem and adjacent areas) potential changes (response to sound), after computer analysis issued a prompt.

The former is particularly commonly used.

  Once their baby cannot pass the hearing screening, parents often become worried and upset.

“Parents need to have a correct understanding of hearing screening results.

“Mai Fei said.

In general, failure to pass hearing screening only indicates that there may be abnormalities in the sense of audiology, that there may be abnormalities in the cochlea, or that the ear canal is narrow or causes a substitution that affects sound (such as early stage, amniotic fluid or meconium may cause the ear canal), It may also be caused by excessive environmental noise or poor cooperation of the child (activity or crying).

In addition, inexperienced inspectors can sometimes affect results.

Therefore, hearing screening is just a screening, not a detailed audiological assessment. The screening report is generally not written as normal or abnormal, but is expressed as “negative” or “positive”, “passed” or “failed””Wait.

If the first screening test fails, parents do not have to worry too much, but they must review it further.

If it fails to pass after 2-3 reexaminations, a brainstem auditory evoked potential test should be used to make a clear diagnosis within 3 months after birth.

  Intervention before the age of 1 with hearing impairment is best before the age of 3, especially before the age of 1, which is a critical period for the development of children’s language center.

If you have hearing impairment in the Air Force, you will not be able to acquire normal language skills and will not even speak for a lifetime.

Mai Fei said that only a small number of children can recover or improve their hearing through surgery or medication, and most children can only rely on induced hearing aids for hearing compensation.

Patients with severe hearing loss and total blindness, even with hearing aids, will not help. Implantation of cochlear implants, combined with hearing function training, speech therapy, and language training, will enable children to gradually understand the sound and avoid the development of dumb disorders.

It is best to start the intervention at 6 months or earlier, and the specific steps need to be completed under the guidance of a specialist.

  Studies have shown that if a child is found to have hearing impairment at birth, after rehabilitation language training, he can master 300 to 700 words by the age of 3; if he is not found to have hearing impairment by the age of 2, even rehabilitation training, to 3At the age of only less than 100 words.

  ”For hearing children who can’t be treated, they can be taught to do the best early exercises, correct hearing aids in time, and start auditory language training as soon as possible.

Mai Fei said that after language training, children can communicate with others normally, so that they are deaf but not dumb, and disabled but not useless.  Tip: How can a baby’s hearing impairment be prevented?

  At present, the factors of neonatal congenital deafness are not fully understood, but it is found to be closely related to the following high-risk factors: family history of deafness, intrauterine infections (such as cytomegalovirus, rubella, toxoplasma, syphilis, etc.), skull deformities, premature birthOr very low birth weight infants (weighing less than 1500 grams), multiple births, maternal drug abuse (such as gentamicin) and alcohol, maternal diabetes, chromosomal abnormalities, and some syndromes related to sensorineural or complication deafness.

  Some newborns are unable to hear at birth, but can suffer from hearing impairment due to various acquired factors, such as meningitis, use of ototoxic drugs, severe jaundice, severe suffocation, and other serious illnesses, living in the neonatal care unit for a long time,High risk factors for hearing impairment.

  Experts, pregnant women strengthen their awareness of personal health care, prevent others from unnecessary contact, strengthen health care during pregnancy and perinatal period, and prevent infections and newborn diseases, which can reduce the incidence of hearing impairment to a certain extent, but due to the causeComplicated, complete prevention of the disease is not yet possible.

Therefore, strengthening newborn hearing screening, timely detection of hearing impairment and early medical intervention are the most effective preventive measures for deaf children.
