The amniotic fluid contains the cells of the unborn baby (fetal cells) and the biochemical substances produced by the baby. By examining these fetal cells and biochemical substances, chromosome structure of the baby, genetic disease scans, placental transit infection and metabolic disease diagnosis can be made.
Amniocentesis is an interventional diagnostic test that will provide important information about the health status of the baby. It is very important to inform the couple in detail before the application.
Genetic AmniocentesisTo learn about the chromosome structure of the baby 16-20. between weeks of pregnancy. The application of genetic amniocentesis can be considered in the following cases;• Prenatal screening tests have abnormal results • Have a history of pregnancy with chromosomal disorders • Pregnant mothers 35 years and older • Ultrasonographic anomaly detected in the baby • The mother or father is a carrier of a known genetic disorder Other reasons for amniocentesis;• To investigate the presence of an infection in the infant • To reduce the amount of amniotic fluid in polyhydramnios (amniotic fluid) • To determine the degree of disease if the couple develops blood incompatibility and Rh disease • 32-39. In order to determine the lung development of the baby, if there is a pathology that requires birth in the pregnant or infant between the gestational weeks
risks• Low Genetic amniocentesis between 16 and 20 weeks of gestation carries a low risk of 1/300 - 1/500.• Cramping and vaginal bleeding• Amniotic fluid flowRarely, the tear area may heal spontaneously and progress to normal pregnancy or lead to infection and miscarriage. Development of Rh SensitivityIn couples with blood mismatch, Rh immunoglobulin injections are applied to the pregnant woman after the procedure and in this way, the mother with the blood group Rh (-) is prevented from forming immunity against Rh (+) blood cells. This precaution is to prevent the transfer of protective antibodies from the mother to the fetus whose blood type is Rh (+) in later pregnancies. Rarely, Rh disease may develop despite a protective needle. InfectionThe procedure is performed under sterile conditions and rarely develop infection.
How to Prepare?There is no special preparation before the amniocentesis procedure. The expectant mother does not need to be hungry. The specialist must be informed in detail before the procedure. Only the expectant mother and her husband can decide how the pregnancy will continue according to the amniocentesis procedure and outcome. Therefore, all medical information is passed on to the family and they are expected to make a decision. An am informed consent form 'will be requested to sign the transaction.
Amniocentesis is performed under clinical conditions. The expectant mother is asked to lie still. The skin and abdominal wall will be passed to the uterus by ultrasonography with a fine needle. Generally, anesthesia is not applied. Burning as the needle passes through the skin and cramping can be felt when entering the uterus. The procedure will be completed in 2 minutes.
After OperationAfter the procedure, the baby's heart beat is checked. The taken fluid is replaced automatically. It is recommended that the expectant mother rest on the day of the procedure and return to normal life the next day.
ResultLung maturity tests result in several hours, infection tests a week, genetic scans within 15-20 days. The doctor and genetic counselor will inform the family in detail.Conditions to be notified to the doctor;• fever • vaginal bleeding • amniotic fluid flow • cramps lasting more than a few hours
