How to prevent children from being born deaf?
Many abnormalities of the fetus can be accurately measured during pregnancy, but whether the hearing is normal cannot be determined. It can only be determined after the baby is born and undergoes a hearing screening. Do you know how to prevent the baby from being born deaf? I hope today’s sharing can help everyone.
It is necessary to widely publicize the basic knowledge of preventing congenital deafness, and to carry out universal screening and screening of newborns, so that more newborns can pass the census and screening. Understand the hearing status. If there is congenital deafness, early intervention and treatment should be carried out according to the cause. At the same time, you should also understand the causes of acquired deafness. This will have a good promotion effect on the protection of children's hearing.
1. Be sure to do a good pre-pregnancy check-up. Hearing problems are hereditary, so genetic testing must be done.
2. Expectant mothers must not take drugs indiscriminately. Medications have certain side effects, such as antibiotics, antipyretics and analgesics, which all have the risk of damaging hearing.
3. Many pathogens can affect the baby through the placenta, so expectant mothers must pay attention to their health throughout pregnancy, pay attention to balanced nutrition, appropriate exercise, and enhance the body's immunity. Don't be careful about colds and fevers affecting your baby's health.
4. Mom should also stay away from tobacco and alcohol. The impact of tobacco and alcohol on the fetus is huge, especially cigarettes. Smoking or second-hand smoke in pregnant women will hinder the growth and development of the fetus, causing developmental abnormalities in the fetus, including hearing.5. Pregnant mothers must supplement iodine appropriately during the entire pregnancy. Iodine deficiency can cause cretinism, fetal growth and development disorders, and even developmental malformations of the middle and inner ears leading to deafness.
6. Pregnant mothers must avoid noise and listen to some soothing music to maintain a peaceful mood. Do not listen to high-decibel music such as rock music, which may indirectly damage the baby's hearing.
In short, throughout the pregnancy, pregnant mothers must be particularly careful, protect themselves, and prepare the best for the ten-month pregnancy and delivery. Prepare.
Examination of congenital deafness
Comprehensive and systematic collection of medical history, detailedEar and nose examination, strict hearing function, vestibular function and Eustachian tube function testing, necessary imaging and systemic examination are the basis for diagnosis and differential diagnosis. Objective comprehensive analysis is its premise.
1. Ask the medical history in detail to determine whether the time of onset of deafness is congenital. Prompt parents to recall according to the normal baby's hearing and speech development rules to provide diagnostic clues. For example, normal newborns should be frightened by sound. Jump reflex, you should be able to pay attention to and find the source of sounds after 4 months, and start babbling from September to December.
2. Obtain clues to the cause of the disease and understand whether there are high-risk factors for hearing loss.
(1) Factors during the fetal period: ① There are deafness patients in the family or immediate relatives, especially those whose deafness was discovered in childhood; ③ Parents are consanguineous; ② The mother has a history of viral infection during pregnancy; ④ The mother uses ear therapy during pregnancy History of toxic drugs; ⑤The mother suffers from metabolic disease or endocrinopathy.
(2) Factors in the neonatal period: ① Abnormal craniofacial structure or malformation; ② Blood bilirubin is exceeded; ③ Birth weight is less than 1500g; ④ Apggar score is less than 5 in 5 minutes; ⑤ NICU monitoring history.
3. Otology and systemic examination to determine whether there are deformities or intellectual developmental disabilities.
4. For audiological examination, appropriate testing methods can be selected according to the age of the child and equipment conditions, such as brainstem electrical response audiometry or otoacoustic emissions.
5. CT scan can determine whether there are malformations of the cochlea in the inner ear and the vestibule or internal auditory canal. It can also be found whether there is bony atresia in the external auditory canal or middle ear deformity.
