Recently, a lot of pregnant moms have been asking if they have to have an amniocentesis. It sounds scary, but amniocentesis is one of the prenatal screening programs. However, amniocentesis is one of the prenatal checkups, in which a specimen of amniotic fluid is extracted from a pregnant woman to obtain information about the health and development of the fetus. Mothers ~ in order to the baby’s health this little bit of pain really have to endure Oh ~ amniocentesis (referred to as amniocentesis, amniocentesis) is the ultrasound-guided localization of the extraction of amniotic fluid to carry out fetal chromosome karyotyping and determination of alpha-fetoprotein, but also for some hereditary diseases to carry out a number of genes and enzymes, the following chart. Because amniotic fluid contains skin cells shed by the fetus and kidney cells in the fetus’ urine, after the amniotic fluid is extracted, the testing personnel will carry out a series of complicated processes such as centrifugation, culture, staining, reading, etc., to finally obtain the chromosome karyotyping results of the fetus, and in addition, the amniotic fluid will also be sent to be examined for alpha-fetoprotein. Generally speaking, amniocentesis is safe, and the rate of occurrence of various risks ranges from 1/250 to 1/300, that is to say, there are 3 to 4 cases of pregnant women in every 1,000 punctures that may have problems, usually bleeding, miscarriage, infections, leakage of amniotic fluid, injury to the fetus, and sometimes uterine deformities, uterine fibroids, placenta located in the anterior wall of the uterus, the abdominal wall is too thick, and the amount of amniotic fluid is low, and so on, the amniocentesis may occur Failure. There are also various reasons why amniotic fluid cells do not grow or grow unsatisfactorily after culture and thus no conclusion can be drawn. What are the things to be aware of when having an amniocentesis? For pregnant women, it is important to urinate and empty the bladder before the puncture. During the procedure, do not be overly nervous, relaxation is the best cooperation, the pain level of the puncture is similar to the usual pain of intramuscular injections, the more tense the abdominal muscles will feel the more pain, the doctor will do a good job of positioning before the puncture, and will not cause harm to the fetus in general. After the puncture, you are forbidden to have sex for 2 weeks, you can rest appropriately, do not take a shower on the same day, and the dressing on the puncture point can be removed on the next day. If there is stomach pain, vaginal bleeding, vaginal fluid or fever should go to the emergency room in time. There are also some special groups of people, such as twin pregnant women, the need for two fetuses separate puncture, the doctor will use a special method to distinguish between the amniotic fluid of the two fetuses; there are also special blood type Rh-negative blood type of pregnant women, the puncture procedure has an increase in the exchange of blood between the fetus and the mother, increasing the risk of hemolysis of the newborn, need to be injected with Rh immune globulin for active immunity; a similar situation with active hepatitis B, patients. Similarly, in patients with active hepatitis B, the puncture may increase the risk of vertical transmission of the hepatitis B virus to the fetus, and hepatitis B immunoglobulin injection is also required. In addition, if you have a fever or abnormally high white blood cells before the procedure, your doctor may suspend or postpone the procedure to make sure there is no infection before performing the procedure. Will I know if the fetus is normal as early as possible after the amniocentesis procedure? Routine amniocentesis is followed by a series of complicated steps such as culturing, harvesting, staining, and reading of amniotic fluid for fetal chromosome karyotyping, which requires several weeks of waiting time. These weeks are a torment to the pregnant woman and her family, especially as the weeks of pregnancy gradually increase and the fetal movement becomes more and more obvious, the fear of being told that there is something wrong with the fetus after a few weeks and that labor will need to be induced is even greater, so there is a clinical need for a rapid diagnosis.
