An explanation of the AmniocentesisAn explanation of the Amniocentesis - Amniocentesis is a procedure performed during pregnancy to examine amniotic fluid samples. This procedure is useful for knowing whether or not there are abnormalities in the fetus. If needed, an amniocentesis will be recommended for pregnant women when the gestational age reaches 15-20 weeks.
In the amniocentesis procedure, the doctor uses a special needle to take a sample of amniotic fluid (amniotic fluid), by inserting it into the mother's stomach to the uterus. The doctor will examine fluids containing cells to provide clues about the condition of the fetus.
Cells are examined based on the size and number of fetal chromosomes, which indicates if there is a risk or disorder that endangers the fetus, one of which is to know Down syndrome.
Indications of AmniocentesisDoctors recommend an amniocentesis procedure when gestational age is 15-20 weeks. Does with the aim of:
Knowing fetal chromosome abnormalities before birth. Amniocentesis examination cares out if after a pregnancy ultrasound examination a fetus is suspected of irregularities.
It knows fetal lung development.
Evaluating fetal abnormalities due to alloimmunization, namely abnormalities due to the response of the immune system or maternal immunity that are transfer to the fetus, and cause problems for the fetus. These alloimmunization abnormalities are abnormalities due to an incompatibility of rhesus (rhesus incompatibility) or hydrops fetalis. If rhesus incompatibility does not detect from the start, it can endanger the fetus' condition.
Treatment for polyhydramnios, namely by giving the drug directly into the membranes, to reduce pressure in the uterus. Amniocentesis can also be used to deliver drugs directly to the fetus.
Abnormalities in the fetus are more prone to occur in pregnant women with the following conditions:
Aged over 35 years.
Warning of Amniocentesis
- Lack of amniotic fluid (oligohydramnios).
- There are Abnormalities on the position of the placenta.
- Have an allergy to anaesthesia, latex material, or adhesives.
- Are using other drugs, such as blood thinners.
- Have a history of blood clotting disorder disease.
- Difference between rhesus blood group and fetus.
- You have hepatitis or HIV.
Before AmniocentesisAn explanation of the Amniocentesis - There is no special preparation before undergoing amniocentesis. Pregnant women also do not need to fast before taking action. In some cases, pregnant women are encouraged to resist urination, because this procedure is easier to do when urine meets the urinary tract. Ask your husband or family to accompany and accompany you during the process.
The doctor will ask you to lie down comfortably on the examination room bed. The doctor will help to position yourself to the lithotomy position, the position lying flat, knees and hips bent, and the legs will support.
When you are lying comfortably, the doctor will use an ultrasound to check the condition of the fetus, fetal heart rate, placental location, and location of amniotic fluid.
The doctor will use an anaesthetic that is injected around the abdomen to reduce pain. However, anaesthesia is not always used in amniocentesis because the effect is not very important.
Ultrasound also uses as a guide to inserting needles into the abdominal wall until the tip of the needle is in the centre of the amniotic sac. The doctor will take about 30 ml (about two tablespoons) of liquid. This procedure is short, which is about 30 seconds to several minutes.
If you take enough fluid, the doctor will carefully pull the needle out of the stomach. After that, the doctor will apply antiseptic liquid and cover the puncture area in the abdomen with a bandage.
After an amniocentesis, the doctor will check the fetal heart rate with a particular device, ensuring that the fetus does not experience stress. If you have a negative rhesus blood group, and the fetus suspect of having a positive rhesus blood type, the doctor will give Rho injections after the procedure. Rho injections aim to prevent alloimmunization reactions to the fetus.
The doctor will allow you to go home and suggest resting at home, and avoid activities with repetitive movements and sexual relations for 1-2 days.
