Let us dive into the topic of Amniocentesis, which is an important prenatal diagnostic test.

In this video, I will cover the role of Amniocentesis in a healthy pregnancy-Why the procedure is done? What happens during the procedure? When is it performed ? and the complications you should be aware of?

So, let’s get started!

Amniocentesis is advised for pregnant women when there is a higher risk of genetic or chromosomal abnormalities suspected in the baby. Usually, this procedure is advised when there are abnormal results in the pregnancy scan, double marker, quadruple marker,  NIPT, or when there is a family history of genetic conditions.

Amniocentesis is a medical procedure done to get a small sample of amniotic fluid surrounding the developing fetus in the uterus. This procedure is usually performed after the 16th  week of pregnancy.

The first step of the Amniocentesis is to review relevant medical records and test reports, explain the procedure and potential risks to the couple, and take consent for the amniocentesis procedure.

In the next step, the Radiologist will use ultrasound guidance to locate the position of the needle. Once the optimal spot is identified, a small dose of local anesthesia is given to numb the area. Then a thin long needle is gently inserted through the mother’s abdomen into the amniotic sac. After confirming the needle position, around 20ml of amniotic fluid is withdrawn using a syringe carefully avoiding contact with the fetus.

Then the needle is removed, and a small bandage is placed over the puncture site.

After the procedure, the amniotic fluid is sent to thr laboratory for further analysis like FISH, Karyotyping, Microarray tests, etc., depending upon the problem suspected in the unborn baby.

The lab tests can provide vital information on chromosomal abnormalities, genetic disorders, neural tube defects, and certain metabolic conditions.

After the procedure, the mother is observed for a few minutes, and if necessary, TT and progesterone injections are administered to the mother.

The lab results usually take about 4 to 15 days, depending on the type of test advised.

Amniocentesis is a relatively safe procedure. However, some complications can occur rarely, like miscarriage and preterm delivery, which can be 1 in 1000 procedures. The procedure-related complications depend on the expertise of the doctor.

Remember, this test is an important tool providing valuable information about your baby’s health. 

Amniotic fluid, also known as Liquor amnii, is a fluid that surrounds the baby in the womb. Amniotic fluid is essential for the baby’s development and protection, as it cushions and provides a favorable temperature. Abnormal amniotic fluid levels in pregnancy can indicate a potential complication, such as infection, fetal growth restriction, fetal abnormalities, and preterm labor.

Ultrasound scans are the only means to measure amniotic fluid levels during pregnancy.

Reduced amounts of amniotic fluid is called oligohydramnios, where the single vertical pocket of fluid is less than 2cm or AFI less than 8. Oligohydramnios can be due to placental problems, premature rupture of membranes, or fetal abnormalities, especially kidney problems.

An oligohydramnios is treated by improving mothers’ nutrition, hydration, and arginine supplements.

An increased amniotic fluid is called polyhydramnios, where the single vertical pocket of fluid is more than 8 cm or AFI of more than 20.

Polyhydramnios can be due to gestational diabetes, fetus infections, or fetal abnormalities, especially intestine problems in the baby. But in most cases, there is no cause found for polyhydramnios. Hence no treatment is done.

An abnormal liquor level can impact the pregnancy and mode of delivery, so it is important for follow-up scans and proper treatment.

Five things you gotta know about ectopic pregnancy!

1.What exactly is ectopic pregnancy?

the fertilized egg camps outside the uterus, typically in the fallopian tube.

2.Where can these ectopic pregnancies happen?

the fallopian tube is their favorite spot, but rarely ectopics can happen in the ovaries, abdomen, or even the cervix.”

3. here’s the scary part: ectopic pregnancies bring some serious risks, like ruptured tubes and dangerous bleeding. Quick medical help is a must to avoid these dangers and keep mother safe.”

4. What are the reasons for ectopic pregnancy?

Things like past ectopic pregnancies, pelvic infection or inflammation, uterus surgeries, or endometriosis are the common reasons for ectopic pregnancy.

5. lastly, why is early detection so crucial?

”Early diagnosis is crucial for  making life safer for the mother. That’s why early prenatal visits and early pregnancy scans are a must.

The earlier ectopic pregnancy is detected, the better the management options, which can include medication or surgery.”d your and your doctors control.

NIPT, or Non-invasive Prenatal test, is a simple blood test performed on pregnant women to detect potential genetic and chromosomal abnormalities in the unborn baby.

NIPT is usually done anytime after the 10th week of pregnancy. The test results take 10 to 14 working days.

Here are some common situations where the doctor recommends NIPT

1. When the pregnant women age is more than 35 years
2. When there is a family history of genetic conditions.
3. When double, triple, or quadruple markers tests show a high risk for chromosomal abnormalities.
4. When the ultrasound scan indicates chromosomal abnormalities.

NIPT analyzes the baby’s DNA in the mother’s blood and provides information about the baby’s risk of chromosomal abnormalities.

Unlike prenatal procedures such as amniocentesis and CVS, NIPT is non-invasive and poses no risk to the developing fetus, which means no risk of miscarriage.

NIPT has a 99% sensitivity and specificity for detecting chromosomal abnormalities.

A negative test result means chances of chromosomal abnormalities are extremely unlikely. Since NIPT is a screening test, a positive NIPT result should be confirmed with further diagnostic tests such as amniocentesis or chorionic villus sampling 

Baby has to grow incrementally inside the Uterus throughout the pregnancy. But sometimes, the baby doesn’t grow as expected. This condition is called Fetus growth restriction(FGR).

Three main factors cause the baby’s growth restriction

1)Issues with the placenta, which leads to poor blood supply to the baby

2)Inadequate nutrition intake by the mother

3)Genetic abnormalities in the baby

But worry not! Here are five important tips to improve your baby’s weight.

1) Do not miss your first-trimester scan. Your first trimester scans predict if there are any placental abnormalities by using Doppler study. In such cases, your doctor will advise blood thinner medicines to improve blood circulation to the baby.

2) Consume a well-balanced diet with essential nutrients like protein, iron, calcium, and folate. You may consult a nutritionist for better results.

3) Stay hydrated! Drink plenty of fluids to ensure your body functions properly and helps in nutrient absorption.

4) Get regular prenatal check-ups, which help to detect issues early and provide necessary guidance.

5) Stress management. Mothers should take adequate rest with good sleep for the baby’s growth.

The baby’s position in the uterus is also known as a lie or presentation. The four baby positions are

1. Cephalic /vertex Position: This is the most common and ideal position for a baby during Delivery, with the baby’s head facing downwards towards the birth canal. This position helps the baby pass through the birth canal more easily, allowing for normal Delivery.
2. Breech Position: The baby is positioned with its buttocks or feet closest to the birth canal. This position increases the risk of complications, as the baby’s head may get stuck in the birth canal and must be delivered by a C-Section in most cases.   
3. Transverse Position: This is when the baby is lying horizontally across the Uterus, with its head and feet pointing towards the sides. This position is rare, and Delivery must occur by C-section, as the baby cannot safely enter the birth canal.  
4. Oblique Position: The baby is positioned diagonally in the Uterus, with its head and feet pointing to opposite sides. Normal Delivery is usually possible, but the baby must be monitored closely during Delivery.

One can know the baby position with the help of ultrasound scan. 

This is one of the frequent questions I encounter from my patients who come for pregnancy scans.

But the fact is, there are no tests that give you a 100% guarantee that the delivery will be normal or C-Section. However, the chances for normal delivery are more than 80 percent in the following conditions:

1. If it’s your first pregnancy
2. If the baby’s head is down, we call it a cephalic presentation.
3. If the pregnancy has crossed 37 weeks, that is term pregnancy.
4. If the labor pain starts on its own.

Even if all these conditions are met, there is no guarantee that it will be a normal delivery.

You might go through the labor pain, but several factors like the cord around the baby’s neck, Fluctuation in the baby’s heart rate, Small size of the mother’s pelvis and large baby head, Slow progress of labor, etc may not favor normal delivery and they may rush you to emergency C section.

However, I recommend all expecting mothers to stay active, eat healthily, and practice guided exercises throughout the pregnancy for smooth delivery
