Patient's question:
Doctor, hello: After my amniocentesis, the results showed no nucleus, and I didn't understand whether it indicates a problem with the baby or what. The doctor at the hospital suggested another amniocentesis. Is it necessary? Additionally, if I have another amniocentesis, does it mean two procedures in two weeks could have any negative effects on the baby? I urgently want to know the reason and answer. Please, doctors, give your advice! Thank youDoctor's answer:
Analysis of the condition: Amniocentesis is a method of prenatal diagnosis. It is generally suitable for prenatal diagnosis during the second trimester of pregnancy. Amniotic fluid exists in the amniotic cavity; the amniotic cavity is formed by the fertilized egg on the seventh day of fertilization, and it begins to produce amniotic fluid. At 12 weeks of pregnancy, the volume of amniotic fluid is 50 milliliters, at 20 weeks it is 400 milliliters, at 36-38 weeks it is 1000-1500 milliliters, and it slightly decreases as it approaches the due date.Recommendations: The risk of examining the fetus through the mother is safe, and only one blood sample from the mother is required. However, it can only tell you whether there is a risk, whether this child has the disease or not, and it must be determined through amniocentesis. It is certain that there is a risk, but the overall risk rate, the risk of causing fetal miscarriage, is generally not more than 1%. Moreover, in large and medium-sized hospitals, the principle is that amniocentesis must be performed under ultrasound guidance. That is to say, we must observe under ultrasound to avoid the child and the placenta. Therefore, the possibility of causing damage to the child is even smaller.
