Is amniocentesis risky?

If we want to know whether amniocentesis is risky, we first need to know what principle it uses. Only by knowing the operating principle can we know whether such an operation is dangerous or risky. To put it simply, amniocentesis is a procedure in which a doctor punctures the amniotic fluid to obtain some cells, and then analyzes whether the chromosomes of the baby in the mother's belly are normal, thus avoiding the birth of deformed babies.

Under the guidance of an ultrasonic probe, the doctor uses a thin puncture needle to penetrate the abdominal wall, uterine myometrium and amniotic membrane into the amniotic cavity and extract 20 to 30 ml of amniotic fluid to examine the chromosomes, DNA, biochemical components, etc. of the fetal cells. This is currently the most commonly used prenatal diagnostic technology. The operation is simple, no anesthesia is required before puncture, and no hospitalization is required.

Amniocentesis has been used for prenatal diagnosis for 30 years, and its accuracy and safety have been recognized by the medical community. The difficulty of amniocentesis varies from person to person, and is mainly related to the position of the placenta, fetal position, the amount of amniotic fluid at the puncture site, fetal activity, etc.

About 2 to 3% of pregnant mothers will experience mild uterine contractions and vaginal bleeding after puncture, which usually resolves after rest or tocolysis treatment. Only about 0.5% of pregnant mothers will experience amnionitis, rupture of membranes and miscarriage. Since the puncture is currently performed under the guidance of ultrasound, the possibility of harming the fetus is very small. In addition, amniocentesis is used for prenatal diagnosis between 16 and 22 weeks of pregnancy. At this time, the fetal body, limbs, etc. have been fully developed, so it will not cause fetal malformations.

This method of amniocentesis may have a certain impact on our pregnant mothers, manifested as symptoms of vaginal bleeding, but don’t worry, this has no effect on pregnancy and generally no treatment is required. This situation will not occur if you rest for a few more days. If you are worried, you can go to the hospital for detailed consultation.
