Causes of developmental disorders. Abstract: Causes of developmental disorders in early development Presentation on the topic of causes of developmental disorders of organisms

1. Endogenous - these are all congenital disorders. In this case, we can distinguish:
chromosomal abnormalities (aberrations).
genetic disorders (aberrations).

Chromosomal aberrations - associated with changes in chromosomal

structure or number of chromosomes.
Chromosomes and the genes they contain
constitute units of heredity. IN
components of chromosomes in encoded form are the main
signs of the human body.

Transmitted by heredity only
chromosomes along with the elements they contain
genes. In case of heredity
negative factors operate at the level
germ cells, i.e. if the sex cells
parents are defective, then this may
lead to disruption of hereditary
prerequisites.

What could be the reason for the inferiority of the reproductive cells of the parents?

What can cause the inferiority of parental germ cells?
Unfavorable heredity
or negative influence
external factors on these cells.
Chromosomal aberrations can
appear due to radiation, viral
infections, chemicals.

They always appear at the birth of a child.

Consequence of chromosomal
disorders is Down syndrome,
microcephaly, hearing impairment,
vision, intelligence, unfused
palate, deformation of limbs.

Physical disorders in oligophrenia.

Myxedema cretinism

Gene aberrations are a group of hereditary disorders

Gene aberrations can cause:
mental and physical disorders.
Their consequences may be
intellectual impairments of varying degrees,
skeletal development disorders, deafness,
diseases of the nervous system, disorders
metabolism.

Genes with distorted information can be passed on from generation to generation

or every second generation. Those.
parents may not suffer from
distorted information, but this
negative factor may
affect their children.

Genetic disorders
characteristic of blood ties and marriages.
The closer the blood ties,
the more severe the degree of various disorders
development.
The latest research shows
that only 1/3 of children born in
conditions of incest, is
physically and mentally healthy.

2. Exogenous disorders appear due to the negative influence of the environment.

They can be
congenital (negative factor
affects a child in
mother's womb) and
acquired (negative factor
affects the child directly, not
through mother).

These factors are divided into three groups:

physical factors
chemical,
biological.

1.Physical factors:

1.
2.
Radiation. Similar negative
Large doses can also have an effect
X-rays.
Physical trauma to the abdominal cavity
pregnant. Particularly dangerous
compression in this area, therefore
It is dangerous for a pregnant woman to travel
crowded transport.

. 3.Vibration. Therefore, it is better for a pregnant woman to travel on foot rather than by transport.

4. Temperature factor. Negative

has a high impact on the fetus or embryo
mother's body temperature, since in this case
the body temperature of the fetus and its
requiring more oxygen rather than getting it in
sufficient quantity, the fruit enters
state of partial asphyxia. On the contrary, low
mother's body temperature, constant
the cooling of her body leads to the fact that
development slows down

2. Chemical factors

1.
The primary result of these
factors – intoxication, i.e. poisoning
body of the expectant mother:
Medicines (antibiotics are especially harmful). For example, it was found that treatment
pregnant woman streptomycin leads to
the birth of deaf children, because from this drug
the auditory nerve atrophies.

2.Alcohol, drugs, nicotine.

Alcohol and drug use disrupts
sex cells of parents, slows down physical
fetal development.
Due to alcohol syndrome in 70-90% of children
mental disorders occur; 30% of children with alcoholic
syndrome have severe mental disorders:
dementia, cerebral palsy. Sometimes mental damage
and intelligence are observed already in early childhood, but more often
In general, they are revealed when the child begins to study in
school.

Alcohol is especially dangerous at 7-11 weeks of pregnancy, when they begin to develop

internal organs of the child.
The fetal brain is most affected.
Due to the effects of alcohol on a child's brain
hydrocephalus, epilepsy may appear,
asphyxia, deaf-muteness, neuroses, cardiac and
renal disorders, degeneration
limbs, damage to external and
internal genital organs, progressive
dementia.
(It was revealed that more than 60% of children
those suffering from epilepsy are born
parents who drink alcohol.)

Smoking leads to fetal poisoning
nicotine and has a bad effect on him
normal development. In women who smoke
children are more often born with a weak nervous system
system, which subsequently leads to
behavioral problems in these children.

3. Biological factors -

3. Biological factors
maternal diseases, especially infectious ones,
since the fetus does not yet have any
defense mechanisms. Consequences
the effects of this factor can be
dysfunction of the brain,
vision, heart defects, anomalies
digestive tract, muscles, bones,
deafness, slow development of movements and
child's psyche.

When a pregnant woman suffers from anemia,
heart disease - this causes oxygen deprivation
starvation of the fetus - hence asphyxia (suffocation). From
the duration of asphyxia depends on the degree
damage to brain functions.
Malnutrition of the mother, her age
are also negative biological
factors. The older the woman, the more
her body accumulates harmful substances,
the weaker its reproductive cells.

2. CAUSES OF ACQUIRED DISORDERS OF CHILD DEVELOPMENT

2. CAUSES OF ACQUIRED CHILD DEVELOPMENT DISORDERS
These include:
prolonged labor,
toxicosis,
infectious diseases and intoxication (poisoning)
child's body,
radiation,
birth injuries,
head injuries,
illnesses suffered in early childhood (meningitis,
polio, measles, scarlet fever, influenza, encephalitis).

Meningitis is especially dangerous - acute
inflammation of the lining of the brain and
spinal cord. Meningococcus is found in
the patient's throat. You can get infected from
coughing, sneezing, through toys.
Consequences: blindness, deafness,
dementia.

Poliomyelitis - infectious childhood
paralysis that destroys the central
nervous system.
Encephalitis. The carrier is a tick.
Consequences – paralysis, epileptoid
seizures, intellectual impairment.

Plays an important role in the development of a child
his environment. Great importance
has stimulation for children's development
processes of perception, memory, speech,
motor skills especially in sensitive
periods.

T.O., than before, more global and
the harmful one acts more intensely
factor, the greater the likelihood of common
mental delays or distortions
development.

But the child’s brain is an intensively developing system with high

plastic possibilities.
The insufficiency of one or another function may
partially or even fully compensated for
counting healthy areas of brain tissue.
But after the growth processes are completed and
specialization of brain regions such substitution
functions are difficult (after 15 years. By 15 years
brain maturation completes).

    Summing up the lesson.

    1. Disorders of intrauterine development

    1.1. Causes of endogenous origin

    3.1. Physical factors

    3.2. Chemical factors

    3.3. Biological factors

    1.2. Causes of exogenous origin

    Violations of this type appear due to the negative influence of the environment. They can be congenital or acquired.

    Congenital disorders appear as a result of the influence of negative factors on the embryo or fetus (an embryo is considered to be life from the time of fertilization of germ cells to nine weeks, a fetus is the future newborn in the womb from nine weeks to nine months). Negative factors most strongly disrupt those organs and systems that develop more intensively at this time. For example, the most important period for the development of the organs of vision and hearing is the 3-9th week. Internal organs are mainly formed in the 7-11th weeks. During these periods, these organs and systems are most sensitive and are quickly affected by negative factors.

    Often in the first weeks a woman does not know about her pregnancy and may use antibiotics, barbiturates or other medications that have a negative effect on the embryo, or be under the influence of negative external factors. To avoid such situations, family planning is necessary.

    The most intensive period of embryonic brain development is weeks 2-11. But in general, this most important human organ takes a long time to form, throughout the mother’s pregnancy. Every minute the number of nerve cells increases on average 20,000 times. The brain of a newly born baby weighs about 400 grams and contains about 15 billion nerve cells. However, they perform much fewer functions than the brains of other newborn mammals. It will take years to fully develop (no longer in the womb), during which a network of nerve cells will form. Therefore, for the development of the brain of an embryo, fetus or child under one year of age, exposure to any negative physical, chemical or biological factors is very dangerous.

    2. Developmental disorders after birth

    The causes of developmental disorders in a child can be various injuries (including birth injuries), which damage vision, hearing analyzers, and the brain.

    Birth injuries occur both during prolonged and rapid labor, with incorrect position of the fetus, early breaking of water, discrepancy between the size of the mother’s hips and the size of the fetus. Most often, the newborn's head is injured, which can result in brain hemorrhage, damage to the brain or its covering. Birth injuries can damage the muscles, joints and bones of the newborn (for example, dislocated shoulder, fractured collarbone). During prolonged labor, instrumental assistance is often used. This is very dangerous, since it can damage the bones of the skull that have not yet fused and disrupt the circulatory system of the brain.

    All pathology of childbirth is divided into several groups:

    1) mechanical injuries of childbirth, when during labor the homogeneity of the tissues of the child’s head is damaged;

    2) hypoxia - when due to lack of oxygen the supply of oxygen to tissues is disrupted;

    If the brain is damaged, a newborn may die within the first hour or on the first day of life. More than half of the surviving infants suffer from neurological pathology: from signs of increased nervous excitability to severe paralysis and dementia.

    Diseases suffered in early childhood (including such harmless ones at first glance as influenza, measles, scarlet fever) can also lead to developmental disorders. But epidemic meningitis, encephalitis and polio are especially dangerous.

    Meningitis is an acute inflammation of the membranes of the brain and spinal cord. Most often it is children who get it. The disease is caused by meningococcus or pneumococcus in the patient's throat. You can become infected from a coughing or sneezing patient, or from things contaminated by him (for example, toys). The disease begins suddenly: the child has a headache, high fever, vomiting, and may experience loss of consciousness and epileptic seizures. As a result of this disease, the child may become deaf, blind, and may develop hydrocephalus and dementia.

    The source of the primary encephalitis virus is some rodents, goats, cows and birds. It is mainly transmitted by ticks. The disease begins 1-2 weeks after the bite of an infected tick or from drinking the milk of an infected cow or goat. The child has a fever, pain and dizziness, weakness, nausea, and disturbed sleep. Secondary encephalitis begins in patients with influenza and toxoplasmosis. bruceliosis, rubella. For children and adolescents, this disease can have devastating consequences: mental and intellectual disorders, paralysis and epileptic seizures.

    Poliomyelitis is an infectious infantile paralysis that destroys the central nervous system. Children aged 1 to 5 years are most often affected. Poliomyelitis is caused by a virus. You can become infected through water, writing, dirty hands, and sometimes through the air. When infected, the temperature rises, the head and limbs hurt, a runny nose, cough, and sometimes vomiting occur. After 2-5 days, paralysis of the legs, arms, and muscle tissue occurs. The consequences of polio often remain for life: muscle atrophy, deformation of the arms, legs, and spine.

    The group of causes of acquired disorders also includes poisoning. Poisoning has a negative effect on the entire body, but some substances (alcohol, drugs, mercury) can especially damage the nervous system. Large doses of medications such as gentomycin and syntomycin are very toxic. Poisoning with these drugs can damage the auditory nerve.

    The degree of disturbance in the development of children depends on the strength of the negative factor and the time of its occurrence. The sooner negative factors affect the embryo, fetus or child, the deeper the disorders are. Therefore, the prevention of the mentioned diseases and pathologies is an important factor in the reproduction of a healthy population and, ultimately, the survival of humanity.

    3. Factors of developmental deviation

    3.1. Physical factors

    Radiation has the most negative effect on a developing organism. Man lives under the constant influence of radioactive elements and their decomposition products. Cosmic rays, air, earth, water, plants and all living organisms have a radioactive background. But high radioactivity is dangerous to health and life. A pregnant woman, having received large doses of radioactivity, can give birth to children with various somatic and nervous damage (intellectual impairment, hydrocephalus, microcephaly, limb abnormalities, circulatory disorders, sensory problems). Radioactivity is most dangerous during the formation of organs and systems at the embryonic stage.

    Radioactive potential in the human body can appear due to radioisotope diagnostics and radiotherapy, large doses of X-rays. Harmful radioactivity is created by nuclear weapons tests and accidents at uranium reactors in nuclear power plants.

    Mechanical impact on the abdominal cavity of a pregnant woman can damage the fetus. Compression in this area is especially dangerous, which can even lead to premature birth. Therefore, pregnant women should not ride in crowded public transport during rush hours.

    Vibration can also have a negative effect on the embryo. Therefore, driving trucks, tractors, or operating electric sewing or knitting machines is not recommended for pregnant women.

    High ambient temperatures and increased body temperature of the mother due to any diseases lead to an increase in the temperature of the embryo, due to which its need for oxygen increases. Without receiving the required amount of oxygen, the embryo falls into a state of partial asphyxia. This is why a pregnant woman should not work in hot shops, dry cleaners, catering kitchens and other enterprises where the temperature is constantly high.

    Prolonged hypothermia of a pregnant woman’s body is also harmful, as it slows down the development of the fetus. Therefore, a woman expecting a child should not work in cold shops (at meat-freezing or dairy plants).

    3.2. Chemical factors

    The primary result of the influence of these factors is intoxication of the body (poisoning) of the expectant mother.

    As paradoxical as it may sound, drugs are in first place among harmful chemicals. It is especially dangerous to use new, untested drugs. In the middle of the 20th century, for example, when antibiotics were invented, pregnant women were also actively treated with them. It turned out that the use of streptomycin, in particular, leads to the appearance of deaf children - because of this drug, the auditory nerve atrophies. A new term has even appeared in medicine - streptomycin deafness.

    Sedatives and sleeping pills (barbiturates) are dangerous for the unborn child. They easily penetrate the placenta and accumulate in the child’s brain, liver, and kidneys. Moreover, it has been established that twice as much of them are deposited in the fetus’s body as in the mother’s body. Some sleeping pills cause severe physical degeneration and damage to mental development. Therefore, pregnant women should never take medications on their own. In each case, you must consult a doctor.

    Quinine, which some women use to get rid of pregnancy, has a catastrophic effect on the development of the fetus. Most often, such an attempt ends in failure, and the embryo is irreversibly damaged and subsequently develops with severe impairments.

    Alcohol and drugs negatively affect the development of the internal organs of the fetus, so they are especially dangerous in the 7-11th weeks of pregnancy. The brain, which contains fatty compounds, suffers the most - alcohol destroys precisely such tissues.

    Due to the effects of alcohol, progressive dementia, hydrocephalus, epilepsy, asphyxia, deaf-muteness, neuroses, dysfunction of the heart and kidneys, degeneration of the limbs, damage to the external and internal genital organs may appear. It has been established that more than 60% of children suffering from epilepsy are born to parents who drink alcohol.

    Alcohol and its decomposition products affect the embryo even before fertilization. They disrupt the activity of both female and male genital organs - and they begin to produce defective germ cells (their genetic information changes).

    Alcohol syndrome occurs in 2-3 newborns out of 1000. A child suffering from alcohol syndrome has a small head and chin, a low forehead, a short nose, a flat back of the head, small, often slanted eyes, and a cleft palate. There are degenerations of internal organs (especially often - heart defects), damage to the limbs and genitals. The newborn may be of small weight, with signs of congenital malnutrition. Alcohol syndrome causes mental disorders. They are also increased by the constant trauma to the child’s psyche in families of alcoholics. Sometimes damage to the psyche and intellect is observed already in early childhood, but most often they are detected when children begin to study. Such a child is weak in learning and aggressive.

    Through the placenta, not only alcohol, but also its decomposition products, in particular vinegar aldehyde, which is ten times more dangerous than alcohol itself, enters the waters surrounding the fetus. Constant consumption by the mother of 75-80 g of vodka, cognac or 120-150 g of weaker alcoholic drinks (including beer) can cause fetal alcohol syndrome.

    A child born from alcoholic parents inherits a weak nervous system and some metabolic characteristics, which in the future is expressed by a tendency to alcohol. In order for a healthy child to be born, parents must not drink alcohol for at least two months before conception.

    Maternal smoking leads to nicotine poisoning of the fetus. Nicotine remains in the placenta and amniotic fluid, so the negative impact on the fetus is long-term.

    Smoking in women increases the pathology of pregnancy, the risk of premature birth, trauma during childbirth, and increases the mortality rate of newborns. Children are born underweight and with a weak nervous system.

    The chemicalized environment has a hidden negative effect on the fetus. Children are born without obvious signs of disorders, but already in the first weeks signs of diseases such as meningitis, encephalitis, etc. may appear. The negative effects of chemistry can manifest themselves in various diseases even at an older age of the child.

    A pregnant woman should not work in a chemical plant, in a galvanizing shop, in a chemical warehouse, in radio and television production shops, or where soldering work is carried out, during which harmful lead fumes are released.

    3.3. Biological factors

    In a pregnant woman, toxoplasma enters the fetus through the placenta, through its circulatory system it enters the brain and multiplies there. On X-rays, Toxoplasma colonies are visible as white spots. The disease causes severe damage to the brain and vision. The consequence is often mental retardation.

    Examples of viral infections are rubella, influenza, syphilis, infectious hepatitis (liver inflammation), measles, paratitis (mumps), chickenpox, polio, cytomegaly. The latter, in particular, affects up to 30% of newborns - during childbirth or through breast milk. A baby after cytomegaly suffered by the mother is born with a congenital heart defect, anomalies of the digestive tract, muscles, and bones.

    The most dangerous disease is rubella. If a mother becomes infected with it during the first three months of pregnancy, the fetus may die. Or be born deaf, with a congenital heart defect, congenital rubella, congenital blindness, cataracts.

    Viral infections greatly damage the embryo, since it does not yet have any protective mechanisms. Diseases suffered by the mother in the last months of pregnancy are less dangerous and often do not cause any disturbances in the development of the fetus.

    The effect of a viral infection depends on whether the placenta allows one or another type of bacteria to pass through. The paradoxical fact is well known that such a serious disease as tuberculosis during pregnancy harms the fetus only because of the general poor condition of the mother: high temperature, disturbances in the functioning of the heart, and breathing. The placenta does not allow Koch's bacillus to pass through, so the fetus becomes infected with tuberculosis infection very rarely.

    Mother's diabetes or dysfunction of her thyroid gland leads to impaired development of the child's intelligence. With diseases of the heart and blood vessels, kidneys and liver, the mother’s body, and therefore the fetus, lacks oxygen. The child may be born with congenital heart failure.

    Rhesus conflict. Rh factor is an antigen of red blood cells. About 85% of people have it. This factor is inherited as a dominant trait that does not change throughout life. In people who have the Rh factor, the blood is considered Rh-positive (Rh+), while those who do not have it, the blood is Rh-negative (Rh-). When the parents' Rh factors are different (maternal Rh- and paternal Rh+), the fetus can inherit the father's Rh factor. Then, during childbirth, when the placenta is separated, the red blood cells that enter the mother’s blood act as an antigen and irritate the mother’s body. During the next pregnancy, even a small amount of fetal red blood cells entering the mother's body causes the appearance of antibodies. Antibodies can enter the fetus through the placenta and cause the decomposition of red blood cells. You develop a so-called Rhesus conflict, which can cause the fetus to be born prematurely or die. Sometimes such a newborn is born with heyaolysis, a disease of newborns. As a result, anemia begins, blood circulation and metabolism are disrupted, and oxygen deficiency appears. Therefore, it is dangerous for a woman who does not have the Rh factor to terminate her pregnancy, especially her first one.

    Every person must know not only his blood group, but also what his Rh factor is. When the Rh factors of the husband and wife do not match (Rh-), it is recommended to have only one child (otherwise it is difficult to avoid complications).

    The cause of developmental disorders of the child may be previous abortions suffered by the mother. During this operation, an infection may enter the uterus, which in a way “dormants” until the next pregnancy begins.

    The consequences of abortion can be infertility, ectopic pregnancy, miscarriage, and the birth of weak, sick children. A particularly common consequence of abortion is premature birth. The mortality rate of such newborns is many times higher than the mortality rate of full-term children. Premature babies often suffer from pneumonia. Due to inadequate development of the liver, they develop severe forms of jaundice, the intestinal microflora is formed incorrectly, and disturbances in muscle tone and the central nervous system appear. They experience damage and circulatory disorders to the brain. Almost 70% of these children have a cerebral hemorrhage.

    Biological causes of disturbances in the intrauterine development of a child can also include poor nutrition of the mother (malnutrition, starvation, diets), when the body does not receive vitamins, proteins and other substances in sufficient quantities.

    Educational activity of mentally retarded schoolchildren The most important characteristic of mental retardation is a persistent and pronounced impairment of the cognitive sphere, which complicates the formation of educational activity. Underdevelopment of cognitive interests. Violation of her focus and motivation. Weakness in task orientation. Inability to plan and foresee the result. Uncritical attitude towards the results of activities. Inability to notice and correct mistakes. Among the important conditions for the formation of interest in learning in such students is reliance on the child’s life experience, tasks that are entertaining in form, and the creation of situations of success. Labor activity is of great importance in terms of correcting mental deficiencies characteristic of mentally retarded schoolchildren. At the same time, students with intellectual disabilities have a noticeably reduced intellectual side of work, limited creativity, and difficulty developing conscious work skills.

    Children with complex defects Organic damage to the central nervous system sometimes leads to complex defects, which are a combination of 2 or more developmental disorders. Children with developmental anomalies of sensory functions (vision, hearing) in combination with intellectual disability (mentally retarded blind or visually impaired, mentally retarded deaf or hard of hearing children who have a combination of various sensory impairments (deaf visually impaired, blind hearing impaired, deaf-blind). combination of musculoskeletal disorders -motor apparatus with sensory or intellectual disorders. A complex defect is not just a mechanical combination of various defects, but a qualitatively special state of the human body. A combined defect distorts mental development to the greatest extent, as a result, the ability to interact with the outside world is sharply reduced.


    Causes of child development disorders

    Hereditary diseases.

    1 morphan syndrome 2 klyfelterra


    Mental trauma of a pregnant woman Social problems






    Diagnosis of developmental disorders

    • Screening
    • Diagnosis by pedigree
    • Prenatal diagnosis of the fetus ( Invasive methods And Ultrasound scanning of the fetus)

    Diagnosis by pedigree

    • IN The basis of the pedigree is the medical history of all relatives and ancestors.
    • If a hereditary disease is detected in a family, a specialist will determine how it is transmitted and what the percentage of risk of its transmission to offspring is.

    Genetic analysis of parents

    • - study of chromosome set
    • When rearrangements in the chromosome set of spouses are identified in time, a special examination during pregnancy is possible, which will prevent the occurrence of problems.

    Prenatal diagnosis of the fetus

    • - intrauterine examination of the fetus, direction to identify hereditary diseases and developmental defects.

    Invasive methods

    • - invasion of the uterine cavity to take material for research in order to determine the karyotype of the fetus and exclude pathologies such as Down's syndrome, Edward's syndrome and others. They are carried out according to strict indications.

    Ultrasound scanning of the fetus

    • - non-invasive examination of the human or animal body using ultrasonic waves.
    • is considered a safe way to obtain information.

    Correction methods:

    • Prenatal treatment ( Hydrocephalus)
    • Blood transfusion before birth ( Hemolytic disease of the fetus)
    • Fetal surgery ( Cavity and extracavitary )

    Prenatal treatment

    • Treating the fetus in the womb can save the lives of many children. Today, about 10 serious diseases can be eliminated even at the stage of intrauterine development.

    Hydrocephalus

    • Enlargement of the fetal head is a sign.
    • The accumulation of cerebrospinal fluid causes abnormal enlargement of the fetal head.
    • In some cases, intrauterine therapy may be performed, that is, treatment of the fetus at the intrauterine stage of development.

    Hydrocephalus is only a symptom and can be due to several causes, which may include spina bifida, meningitis and omphalitis.


    Blood transfusion before birth

    • Blood transfusion to the fetus by injection into the mother's abdominal cavity; used for severe forms of hemolytic disease of the fetus.
    • Cordocentesis is a blood transfusion procedure that allows blood to be injected directly into the fetal circulatory system through the umbilical cord.

    Hemolytic disease of the fetus

    • A pathological condition resulting from incompatibility of the blood of mother and fetus for certain antigens.
    • The child's blood, containing red blood cells ready for destruction, is almost completely replaced with carefully selected donor blood, which will be resistant to the action of maternal antibodies, since it does not contain the “problematic” antigen.

    Drug treatment of the fetus

    • Drug treatment is used mainly to speed up the development of the fetal lungs.
    • A child born with underdeveloped lungs may develop respiratory distress syndrome.

    • If the doctor monitoring the pregnancy believes that the baby may be born before the 34th week of pregnancy, then corticosteroid injections may be prescribed.
    • A less common condition that can be treated before the baby is born with medications is heart failure.

    Fetal surgery

    • eliminates various problems associated with the development of a child during intrauterine life.
    • Many problems can be eliminated, including urinary tract blockages, tumors and fluid in the lungs.
    • are carried out only after 28 weeks of pregnancy.

    Abdominal surgery

    • During abdominal surgery, the surgeon makes an incision in the anterior abdominal wall and partially pushes out the fetus. After the operation, the fetus is returned back to the uterus.
    • This treatment method can contribute to the onset of contractions, which lead to premature birth.
    • After abdominal surgery, childbirth can only be performed by caesarean section.

    Extracavitary surgery

    • Miniature video cameras and special fiber optic instruments are used to perform such operations, during which a thin needle is inserted into the fetal body.
