What should I do if newborn hearing screening fails? Generally, according to the current hospital regulations, parents are required to let their babies have the first hearing health screening within 72 hours after birth. What should I do if newborn hearing screening fails?
What should I do if the newborn hearing screening fails 1 Under normal circumstances, the newborn will receive the first hearing screening within 72 hours after birth. If the first hearing screening fails, a second screening is needed 42 days after birth.
If the screening still fails, parents should take their children to do a full set of "hearing tests" and make a final evaluation according to the test results to determine whether the baby really has hearing problems.
However, parents should be reminded that if the results of the first hearing screening after birth are not satisfactory, parents should not be too eager to take their babies to major hospitals for examination.
Because from many years of clinical experience, more than 70% of the babies who failed the first hearing screening were due to residual amniotic fluid and earwax blocking the ear canal, which led to unsatisfactory examination results and failed examination. Under normal circumstances, such problems can be ruled out when the baby is screened for the second time in 42 days.
Many parents rushed to take their children to do various tests after their first hearing screening failed. Most doctors don't recommend this, because newborns have weak resistance and too much contact with the outside world can easily lead to diseases.
Influence of different factors on screening results
Research shows that the results of OAE or AABR hearing screening are influenced by many factors, mainly including the following aspects:
1. Neonatal amniotic fluid, fetal fat, and fetal residues remain in the external auditory canal, which will weaken or disappear the stimulating sound and efferent response signal of otoacoustic emission, thus leading to the weakening or disappearance of otoacoustic emission signals. Therefore, it is particularly important to clean the external auditory canal with a small cotton swab before screening.
In addition, the establishment of screening time is also one of the important factors affecting false positives, and premature hearing screening will lead to an increase in false positives. Studies at home and abroad show that the suitable time for primary screening is 48 hours after birth.
2. Neonatal middle ear effusion is the main interference factor affecting the results of 0AE test. Whether the cochlear function of children with middle ear effusion is normal or not, the examination results can be shown as abnormal.
The author thinks that if the screening fails because of the middle ear effusion of newborns, with the absorption of the middle ear effusion, some children's hearing can turn normal in the diagnostic hearing examination three months later, which may be more appropriate to call it "Yang to Yin".
3. Children will be more active or irritable during the screening process. False positives will occur and should be avoided as much as possible. In addition, if the child has a cold, stuffy nose, runny nose, cough or sore throat and heavy breathing sounds, it is recommended to treat him first, and then return to the clinic after the symptoms improve to avoid false positives.
If the child's throat and breathing sounds are serious and repeated treatment is ineffective, it is really necessary to know the hearing situation, and it is recommended to conduct diagnostic hearing testing directly.
4. The technology and operation are not standardized. If the earplug is not completely inserted into the external auditory canal; The plug of the earplug is disconnected from the wire; The test environment does not meet the standards, etc.
What should I do if newborn hearing screening fails? 2 How to train newborns with weak hearing?
Newborns' hearing is weak and they can't exercise through training. It is recommended to go to the hospital for examination and make a definite diagnosis.
Early newborns may be too young, their organs are not well developed or not well coordinated, which will lead to failure. Through the follow-up review, we can further judge whether there is a problem. Children should master the "three early" principle when they find hearing problems: early detection, early treatment and early rehabilitation.
What causes the poor hearing of babies?
1, the baby's resistance is weak, and he often suffers from respiratory infections. Bacteria invade the middle ear, which can cause otitis media. The main symptoms of otitis media are earache, headache, fever and secretion in the ear canal, which will temporarily affect hearing. However, if bacteria destroy the structure of the middle ear, it will permanently damage hearing.
2. Head trauma may damage the eardrum, ossicles and inner ear nerves. External pressure changes too much or too fast, which may damage the eardrum.
3. Some toys will damage children's hearing because of excessive noise, and some will cause irreversible hearing loss, so be careful in the choice of toys.
As long as the baby passes the hearing test, there is no problem with hearing. The baby's reaction was slow when he was a child. He needs an adaptation process. This is not poor hearing, in fact, the baby is too young. When the baby is older, it will slowly respond to the sound after three or four months. This is a normal phenomenon of baby's development, so don't worry.
