Patient's question:
Hello, I am from Chengdu. Recently, my girlfriend needs to have an amniocentesis procedure, but I'm a bit worried because this surgery is something that ordinary people can't do. I want to ask specifically here, which hospitals in Chengdu can perform amniocentesis?Doctor's answer:
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 fertilized egg forms the amniotic cavity on the seventh day after fertilization and 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, and at 36-38 weeks it is 1000-1500 milliliters. The volume of amniotic fluid slightly decreases near the due date.
