What are the causes of miscarriage one week after amniocentesis?

Pregnant women should go to the hospital for regular check-ups, and the items of the check-ups should also be determined according to the woman's physical condition. If necessary, amniocentesis should be performed. After the amniocentesis, you should pay attention to physical changes in a timely manner to see if there is fever, nausea, or vomiting, because these phenomena can easily cause miscarriage. So what are the causes of miscarriage one week after amniocentesis?

First, what are the reasons for miscarriage one week after amniocentesis? Fetal chromosomal abnormalities A large number of clinical studies have confirmed that many fetuses that suffer miscarriage due to amniocentesis actually have problems themselves, such as chromosomal abnormalities. Moreover, chromosomal abnormalities have become one of the main causes of fetal miscarriage.

Second, intrauterine infection

If the expectant mother has an infection before the amniocentesis or fails to perform timely cleaning and hygiene after the amniocentesis, bacteria may be introduced into the amniotic sac during the amniocentesis, causing intrauterine infection. The infection can cause discomfort symptoms such as high fever, uterine contractions and/or abdominal pain, and even miscarriage or premature birth.

Third, after the pregnant woman has completed the amniocentesis, she should pay attention to whether she has any discomfort symptoms such as fever, nausea, vomiting, abdominal or back pain, and whether there is blood with a strange smell or clear liquid flowing out of the vagina. If these conditions occur, miscarriage is likely to occur and she should seek medical treatment immediately. If there is no abnormality in the body after 2 weeks, miscarriage generally will not occur and pregnant women can rest assured.

Fourth, in addition to the possibility of miscarriage, amniocentesis may also have the following risks if not handled properly. The details are as follows:

1. Blood transmission: If the expectant mother has RH negative blood, the examination may sensitize the expectant mother, resulting in hemolysis of the fetus. After the operation, the expectant mother should be injected with anti-D immunoglobulin for prevention.

2. Infection: If the expectant mother has an infection, bacteria may be brought into the amniotic sac during amniocentesis. The infection can cause high fever, uterine contractions and/or abdominal pain, but this situation is very rare.

3. Water rupture: The incidence rate is 1%, and it will heal on its own within a few days.

What are the reasons for miscarriage one week after amniocentesis? The operation is too early. The pregnant woman is less than 14 weeks pregnant and there is not much amniotic fluid in the uterus. Amniocentesis at this time may lead to a lack of amniotic fluid in the uterus after the amniotic fluid is extracted, thus causing miscarriage.
