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?

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.

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.

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.
