When we speak of amniocentesis, always round the ghost of the risk of abortion. But, without wishing to minimise, the risk of fetal loss is really very low.
It is estimated between a 0.2 and 0.5% the chances of suffering a miscarriage after puncture, representing one of every 200 cases. Figure hardly superior to natural spontaneous abortion cases.
True that statistics are no solace to the couple who suffers a miscarriage, but is an increasingly widespread practice with a high margin of safety.
When you do an amniocentesis?
Amniocentesis is a common prenatal test in which a small sample of the amniotic fluid that surrounds the fetus for analysis is extracted.
It tends to occur in women with risk factors such as family history, over 35 years of or for suspected chromosomal defects in the fetus. In any case, many believe that the benefit of confirming the diagnosis is greater than the risk.
Between 1 and 2% of the amniocentesis that are causing loss of amniotic fluid or blood. And a minimum percentage also carries the risk of urinary tract infections.
On rare occasions it can happen that the puncture is difficult and the extracted sample to be analyzed, not serve so a second puncture should be performed, but the chances of that happening are minimal.
According to a study conducted in Canada, the risk of miscarriage It is much higher in amniocentesis performed in the first quarter compared with those made in the second quarter. It also revealed an increase in the risk of foot twisted in early amniocentesis.
Today, professional experience, a good hand and technological advances make this prenatal diagnostic testing more and more secure, but not without risk.
