Amniocentesis sounds risky, what are the how high is the incidence of complications?
Actually amniocentesis is very safe. The risk of complications is less than 0.25%. Ultrasound permits the procedure to take place with few incidences of the needle striking the fetus, umbilical cord, or placenta. Even if the amniocentesis is performed close to term, there is little chance that the membranes will be ruptured or labor initiated. There are a few side effects including temporary cramps, slight bleeding, and the leaking of amniotic fluid. There is no need for additional treatment if you experience any of these symptoms. If you are Rh negative, your doctor will administer an injection of Rh immune globulin. As in all surgical procedures, there is a very small risk that things might go wrong, including severe bleeding, infection and misscarriage. Your doctor will tell you that the incidence of such complications are very low and the benefits far outweigh any potential risks.
