What are the symptoms of congenital deafness in infants

Congenital deafness is not necessarily hereditary. For example, a mother who has certain serious medical conditions during pregnancy can cause fetal deafness. These children are predestined to be hearing-impaired before they are born. Such hearing impairment is congenital, but not hereditary deafness.

Hereditary deafness must be congenital, and it is the genetic defect of the parents that causes the child's deafness. However, some people with hereditary deafness do not necessarily show symptoms of deafness immediately after birth, and the onset may be delayed until puberty or even later. This type of phenomenon is called late-onset hearing loss or genetic degenerative hearing loss.

Contraindications to diphtheria, tetanus

People with central nervous system diseases such as encephalopathy, epilepsy, etc., or those with a history of medical conditions, as well as people with allergies, cannot be vaccinated; Fever, acute attacks of acute illness and chronic illness should be relegated.

If there is a severe reaction (such as shock, high fever, screaming, convulsions, etc.) after the first or second dose, the vaccination of subsequent doses should be stopped.

1.The hereditary factor is that the parents are born with deafness, and the child is susceptible to the disease. But not all of the children born are deaf.

Secondly, consanguineous marriage can also cause natural deafness. In addition, fetal ear tissue development malformations can also cause congenital deafness, but it can be corrected by surgery to restore hearing. 2.

Drug poisoningDuring pregnancy, expectant mothers use harmful drugs, such as gentamicin, quinine and other ototoxic drugs, which can carry on the fetal body through the placenta, resulting in fetal seventh cranial nerve poisoning and deafness. If the mother has been deeply anesthetized during pregnancy, it can also cause hearing damage to the fetus. 3.

If one of the parents has a sexually transmitted disease, such as gonorrhea and syphilis, the child can be born deaf. The mother suffers from rubella, toxoplasma gondii infection, etc., and the virus can cross the placenta and pose a threat to the fetus, causing malformations of inner ear development and deafness. Newborns weighing less than 1,500 grams at birth, suffering from hyperbilirubinemia, severe asphyxia during childbirth, and having purulent meningitis can cause deafness.

4.During childbirth, improper use of forceps during childbirth can damage the child's hearing organs.

There is a lot of genetic factor, and during pregnancy the mother did not take reasonable care of herself, taking some drugs that are harmful to the health of the child. Causes hearing damage to the fetus. And due to improper operation during childbirth, it will also have a certain impact on the fetus.

If you don't eat some fresh fruits and vegetables reasonably before giving birth, the vitamin intake is relatively low. It can also lead to very poor physical development of the baby. Causes a series of diseases.

It is caused by genetics, genes, physically, blood, and psychiatric. And this situation is very serious, so when the baby has this situation, parents must take the baby to the hospital to do the corresponding **.

The baby's congenital deafness may be caused by genetic factors, or it may be that the pregnant mother has been in a noisy environment during pregnancy, so the baby will have congenital deafness.

Caused by genetic factors, drug poisoning, disease damage, prenatal factors, and stunted growth.

Patients with congenital deafness are born or shortly after birth with varying degrees of hearing impairment, that is, they cannot hear sounds at birth, and a small number of patients have a perception of great sounds; Hereditary deafness is accompanied by lesions of the heart, kidneys, bones and other systems.

1. Typical symptoms.

1. Hearing impairment: Patients can be found to have different degrees of hearing impairment at birth or shortly after birth. These children often do not respond to external sounds, and a smaller proportion of patients perceive loud sounds, such as screams and pops.

2. Aphasia: Because the patient cannot hear the voice from birth, and of course cannot hear the speech of the family. The child is unable to perceive human voices and thus cannot imitate them, and the patient has what is known as deafness.

2. Other symptoms.

In addition to deafness, hereditary deafness syndrome type also has lesions accompanied by malformations or systems of tissues and organs such as the heart, kidneys, nervous system, maxillofacial and skeletal systems, metabolic endocrine system, ** and optic organs.

Congenital deafness refers to deafness caused by abnormalities or genetic factors during maternal pregnancy, childbirth, or genetic factors.

It can be found by hearing screening for novices.

In daily life, babies who are more than a month old will be shocked all over the body when they hear a sudden loud sound, close or open their eyes, and even cry. This indicates that the child's hearing is normal, and if there is no such response, it means that there is a hearing problem.

Congenital deafness in children may be caused by genetic factors or non-genetic factors.

1. Hereditary factors. If the deafness gene of the parent is passed on to the offspring, or if the gene is mutated during the development of the embryo, it may cause abnormal development of the eardrum or metabolic disorders, which can lead to the occurrence of hearing impairment. In addition, malformations of the outer and middle ears can lead to conductive hearing loss, while hypoplasia of the inner ear can lead to sensorineural hearing loss.

It should be noted that congenital inherited deafness may be inherited in an autosomal dominant manner, an autosomal recessive inheritance, or a companion hereditary deafness.

2. Non-hereditary factors. It may be related to the occurrence of infection, poisoning, trauma and other injuries during pregnancy or childbirth.

Congenital deafness is a condition in which the hearing organs are impaired or damaged due to various factors during the fetal period, and hearing impairment is pre-existing at birth. **The causes of congenital deafness can be divided into three categories: genetic factors, pregnancy factors, and childbirth factors.

What are the symptoms of infant deafness, the baby's health problems have always been concerned by parents, whether the newborn has congenital diseases is also concerned by parents, some babies will have hearing problems, such as deafness, at this time parents will cry extraordinarily, and we also need to understand whether the baby is deaf as soon as possible, in order to achieve early detection and early **, the following is to share with you what symptoms of infant deafness.

1. Generally, the baby is just born, if you suddenly hear a loud sound, your whole body will be shocked. And there will also be repeated phenomenon of opening and closing the eyes and crying, these symptoms are to indicate that the baby's hearing does not have any problems, if the baby does not have the above reaction and still sleeps peacefully, it means that the baby may be the baby. Hearing problems.

2. If the baby is about 3 months old, the baby who is sleeping normally will suddenly close his eyes when he hears the sound, and his fingers will tremble. If you don't have any of these reactions, you may be hearing impaired.

3. If the baby can basically judge the voice of the parents to 6 months, if the mother shouts the baby's name behind the baby's back, if the baby can find the source of the sound, it means that the baby's hearing is not problematic, if there is no response, it may be poor hearing.

4. Generally, 8 to 9 months old children can take the initiative to make sounds, if she hears others reprimanding her, she will be involuntarily distressed, if she hears others say goodbye to him, she will involuntarily beckon, if there is no response to these sounds, then it also means that the hearing may not be good.

Factors that affect your baby's deafness during pregnancy

1. Infectious factors, such as rubella virus infection, toxoplasma infection, treponemal infection, herpes simplex virus infection, cytomegalovirus infection, etc.;

2. During pregnancy, drugs that affect the development of the fetal auditory system are used, such as hypoglycemic and ototoxic drugs (aminoglycoside antibiotics, antimalarial drugs, etc. If these drugs are used during the first trimester, they are more likely to cause abnormal fetal development;

3. Pregnant women suffer from diseases, such as hypothyroidism, the fetus may be born with congenital deafness;

4. The impact of environmental factors on pregnant women and fetuses, such as radiation injury.

Factors that cause deafness during childbirth

1. Premature birth; 2. Head trauma;

3. Low body weight.

4. Hypoxia and suffocation of fetuses or neonates;

5. Neonatal hemolytic jaundice;

There are many causes of congenital deafness, such as: hereditary deafness, deafness caused by the mother's inappropriate medication during pregnancy, deafness caused by jaundice and other problems at birth.

Patients with congenital deafness are mainly presented with varying degrees of hearing impairment at birth or shortly after birth, and most children are born unable to hear sounds

Congenital deafness, on the one hand, is due to the mother's cold during pregnancy, or the use of some ototoxic drugs, causing the child to be deaf after birth; There is also hereditary, parents or older generations have deafness. Twenty years ago, the medical system was not perfect, and hearing tests were generally not performed after a child was born, so it was difficult to tell if deafness was present at birth. Now, many large hospitals have done a better job in this regard, and the child will have a hearing test within three days of birth, and if there is a problem, the condition will be intervened as soon as possible.
