Chorionic villus is a type of prenatal examination, what should I pay attention to?

Chorionic villus sampling is a prenatal diagnostic technique. In this method, the villi are aspirated with a syringe and the collected sample is sent to a laboratory for short-term or long-term culture for analysis of chromosomal zygotype.

If a pregnant woman needs to have a chorionic villus sampling, the first thing to do is to be strictly disinfected, it is important to perform aseptic procedures, and the first priority is to prevent infection.

The bladder and bowel should be avoided during the procedure, and multiple procedures should be avoided as much as possible at one time, and no more than three operations should be advised.

Some pregnant women with special blood types also need to be injected with immunoglobulin after amniocentesis to focus on preventing infection.

If the results of genetic testing are not confirmed after chorionic puncture, further amniotic fluid testing is required.

Chorionic villus sampling can only be performed after 10 weeks of pregnancy, and if the sample is taken too early, the accuracy of the test results will be affected.

Chorionic villus sampling should not be done in pregnant women with symptoms of threatened miscarriage, signs of infection, or if they have coagulopathy.

First of all, in terms of hygiene, we must pay attention not to get infected, and at the same time, this examination should not be more than three times, the risk is relatively high. Do less.

With the continuous development of social economy, in real life, we will encounter a variety of problems, especially for chorionic villus puncture examination is a kind of prenatal examination, what problems should be paid attention to, and many friends are very puzzled about this, in fact, we must know that chorionic villus puncture examination is a very scientific way of puncture, and can help us diagnose whether the fetus has chromosomal abnormalities, we need to pay attention to the problem is to maintain our own physical health, And some of the appropriate medications should also be stopped before the test.

First of all, we must understand such a problem, that is, chorionic puncture is a kind of silkworm cocoon, and it is also the best way to diagnose hereditary diseases, so when we need to do this examination, we must protect our physical health, to strengthen a certain physical exercise in advance, although we are pregnant, but we can improve our immunity through some simple exercises, and before the puncture, we must prepare accordingly, we must go.

And we must also know that this examination, if our mother is over 35 years old, and has ever conceived or given birth to a defective fetus, or has any family hereditary disease, then the doctor will recommend that our mother at 11 or 12 weeks when the puncture is carried out at the time of the contrast, if the chorionic puncture is carried out earlier, the accuracy of the fetus will be very high, what our mother needs to do is to maintain her physical health in life, Eat more vegetables and fruits, improve your body's immunity, and when the doctor performs a puncture, you can better protect us.

To sum up, we can obviously know that when we perform chorionic puncture, we must protect our physical health and strengthen our physical ability, only in this way can we better protect our own body.

1.To reduce stress on pregnant women2Be sure to cooperate with each other to stabilize the emotional and psychological stress of pregnant women3The day before the physical examination, you should have an empty stomach for 4The night before the check-up, you should take a break and avoid strenuous exercise and emotional agitation.

The following issues should be paid attention to when doing chorionic puncture examination: 1. Keep fasting before the examination, and it is best not to eat after 8 o'clock in the evening on the first day. 2. Chorionic villus examination may induce miscarriage, if you have a history of miscarriage, you must consult a doctor in detail before the examination.

3. The time of chorionic puncture examination is recommended to be between 11-14 weeks, and it is best to lie in the hospital for 2 hours after the examination before going back.

During pregnancy, a chorionic villus puncture is done to determine whether the fetus has chromosomal abnormalities, neural tube defects, and certain inherited metabolic disorders that can be reflected in the amniotic fluid. What can be detected by chorionocentesis in pregnant women?

Chorionic villus puncture is performed at 11-14 weeks of gestation to confirm whether the fetus has chromosomal abnormalities and certain inherited metabolic disorders. It is important to note that a normal chorionic villus test report only means that there is no chromosomal abnormality and does not rule out non-chromosomal causes such as cleft lip and palate. Chorionic villus aspiration is a genetic diagnostic sampling method that can diagnose the presence of Down syndrome or other chromosomal genetic disorders in the fetus by doing fetal chromosomal analysis.

Chorifloresis has an accuracy rate of up to 99%, but this test is expensive and has a higher risk factor than amniocentesis, so it is suitable for expectant mothers who have a high chance of giving birth to a malformed baby.

If the mother is over 35 years old, has been pregnant or has given birth to a defective fetus, or has any family history of genetic disease, her doctor may recommend chorionic villus aspiration at 11-12 weeks of pregnancy. Chorionic villus aspiration is performed earlier than amniocentesis and is done if maternal serum is tested at high risk to confirm the possibility of a fetal chromosomal abnormality. If you are an ordinary normal and healthy expectant mother, there is no need for chorionic puncture.

Nowadays, chorionic villus puncture technology is very sophisticated, although the risk of miscarriage in this test is not higher than that of spontaneous abortion; The chance of other water breakages and infections is also very low, so after weighing their importance, expectant mothers who need to implement it should not worry too much. However, it should be noted that chorionic puncture requires a high level of skill and equipment, so it is important to go to a regular hospital and be guided by an experienced doctor.

1. Have given birth to children with congenital defects, especially children with chromosomal abnormalities.

2. One of the spouses is a carrier of chromosomal abnormalities or balanced ectopia.

3. Carriers of sex-linked genetic diseases, when the sex of the fetus is determined in the second trimester.

4. Those who have given birth to neural tube defects or the serum alpha-fetoprotein value during this pregnancy is significantly higher than that of normal pregnancy.

5. Elderly mothers (over 35 years old) who are worried that the fetus may be abnormal.

6. Screening for high-risk expectant mothers for Down syndrome during pregnancy.

7. Both husband and wife are expectant mothers of carriers of the same type of thalassemia.

8. Ultrasound showed fetal structural abnormalities.

9. There are known or suspected genetic diseases in the family, such as hemophilia, phenylketonuria, etc.
