Is the stillbirth three days after amniocentesis a medical accident?

The "amniocentesis" in the mouth of many mothers refers to interventional prenatal diagnosis. In fact, interventional prenatal diagnosis includes amniocentesis, chorionic villus puncture and umbilical cord blood puncture.

Moms who come to see a doctor due to high-risk prenatal screening, advanced age, or abnormal ultrasound findings want to undergo a puncture examination but don’t know how to make an appointment for surgery? When is the surgery scheduled? What tests are required to make an appointment for surgery? Does your lover need to come together? etc. With these questions, we have briefly listed what pregnant women need to know. We hope it will be helpful to everyone. 1. Which pregnant women need chorionic villus/amniotic fluid/umbilical blood puncture? ?

1. Elderly pregnant women (expected age ≥ 35 years old);

2. Pregnant women with Down syndrome or high-risk non-invasive screening;

3. Those whose prenatal ultrasound shows abnormal fetal development or suspected fetal malformation;

4. One of the couple is a carrier of chromosomal abnormalities or a pregnant woman who has given birth to a child with a chromosomal disease;

5. Couples Both parties are carriers of the same type of thalassemia;

6. Have had a history of adverse births (including multiple spontaneous abortions, teratogenesis, stillbirth, reproductive retardation or children with developmental abnormalities);

6. Fetuses suspected of intrauterine infection (such as Toxoplasma gondii, cytomegalovirus, rubella virus, etc.)

7. Other situations when the doctor deems it necessary to conduct prenatal diagnosis. 2. What is the best gestational age for chorionic villus/amniotic fluid/umbilical blood puncture? ?

Prenatal diagnosis can select corresponding materials according to different gestational weeks. We recommend prenatal diagnosis at 11-14 weeks of chorionic villi, 18-25 weeks of amniotic fluid, and ≥25 weeks of umbilical cord blood. Choose any one of the above three periods.

In principle, early diagnosis is better, but the success rate of chorionic villus culture is relatively low. In a few cases, chimerism requires amniotic fluid or cord blood verification, and cord blood puncture has higher surgical risks than chorionic villus and amniocentesis. High, so amniotic fluid is the main material used in prenatal diagnosis. Taking into account the need to improve preoperative examinations and appointment times, pregnant women with indications for prenatal diagnosis should try not to delay seeing a doctor until after 23 weeks. 3. What does the preoperative examination include? ?

For pregnant women without special circumstances, preoperative examinations include hepatitis B, hepatitis C, syphilis and HIV (AIDS), blood type (ABO RH), TORCH, thalassemia screening for both spouses, and preoperative examination. Fetal ultrasound and more. It needs to be emphasized that we do not recognize the test reports of all hospitals. If the outpatient doctor deems it necessary to reexamine, he will re-invoice the reexamination in our hospital.

Pregnant women with special circumstances, such as the birth history of children with single-gene genetic diseases, couples who are carriers of certain genetic diseases, etc., must have a genetic diagnosis report before amniocentesis. Therefore, I suggest that pregnant women with special circumstances must complete necessary examinations in advance (before pregnancy or early pregnancy) to avoid missing the best gestational age for puncture. 4. What are the risks of miscarriage caused by chorionic villus sampling, amniocentesis, and umbilical vein puncture? ?

Amniocentesis has the lowest risk among the above three sampling methods. The risk rate of premature miscarriage is about 0.1-0.5. Cord blood has the highest risk. The risk rate of premature miscarriage or intrauterine fetal death is about 0.1-0.5. 1. The risk of villi is somewhere in between. 5. What should I pay attention to after puncture? ?

①After the operation, press the needle port on the abdomen for 3-5 minutes and rest for half an hour before leaving if there is no discomfort.

② Avoid moisture and contamination during abdominal needle application for 24 hours, and remove it by yourself one day after surgery.

③Be sure to rest for 1 week after surgery and refrain from sexual intercourse for 1 month.

④ On the 3rd day after surgery, register for prenatal diagnosis in our hospital or a follow-up visit at a local hospital, listen to fetal heart rate, and review B-ultrasound.

⑤ If you experience severe abdominal pain, vaginal bleeding, discharge, frequent or significantly reduced fetal movements after surgery, please go to our hospital or a nearby hospital for examination immediately.

⑥According to the "Maternal and Infant Health Care Law" and "Prenatal Diagnosis and Management Regulations", we will conduct telephone follow-up visits with you one month after surgery and after delivery. We need your cooperation and support! 6. What should I do if I decided to do a non-invasive DNA test at first, but now I want to have amniocentesis? ?

No matter which examination is chosen, it is based on the fully informed choice of pregnant women and their families. If you initially decided to do a non-invasive DNA test and now want to do amniocentesis, it doesn’t matter. Just follow the steps above to make an appointment for the surgery. 7. What should I do if I decided to do amniocentesis at first, but now I want to do a non-invasive DNA test? ?

The principle is the same as Article 6: couples make informed choices. 8. Does your lover need to accompany you to every medical appointment? ?

① During the preoperative examination, your loved one does not need to come. The doctor will tell you when it is necessary to come.

②When you make a formal appointment for surgery, your lover must come because you need to sign an informed consent form.

③ On the day of the operation, your lover does not need to come, but it is best to have someone accompany you, such as running errands, paying fees, chatting... 9. Say important things three times?

① When it comes to whether to choose amniocentesis, don’t hesitate over and over again, lest you end up missing the best gestational age for amniocentesis;

② Don’t listen to what your friends say about amniocentesis or on the Internet. For surgical risks, please consult a professional doctor;

③ Our hospital has implemented an appointment system, please make an appointment in advance to avoid unnecessary waste of time;

④ Non-invasive DNA examination only detects 3 types There is a difference between chromosomal diseases and amniocentesis, which can detect all chromosomes of the fetus. Non-invasive DNA testing cannot replace amniocentesis for the time being.
