What is fetal movement?
During 20-22 weeks you should start to feel your first movement which can be like bubbling in your stomach or waves on your abdomen. Fetal movement is an indicator of fetal wellbeing, so it is important that you become aware of it and call your doctor if anytime you feel your baby movement is less than before
What is Biophysical scan?
Ultraosund scan is done to document the fetus movement : breathing, limb extension, closing and opening of his hands, amniotic fluid volume which is an excellent indicator for placenta function.It can be done 1 or more times per week according to the necessity
What is Non stress test?
A simple non invasive examination which consists of putting two probes on the mother abdomen, one to measure fetal heart rate and the other to measure uterine contraction. The mother presses a button whenever she feels a fetal movement within the 20 minute exam time. The theory is that there should be a deceleration rate and pattern in the fetal heart rate that normally occurs after fetal movement in case of a well oxygenated fetus; if the pattern is not there exams should be done to know if there is a problem due to insufficient placental function, umbilical cord compression or drugs taken by the mother. If the exam results are not comforting prompt delivery should be done.
What is Doppler scan?
a Doppler can detect movement, it can be used to detect blood flow in vessels and is used in certain ultrasound machines while the other type can be used in clinics to hear fetal heart beats (sonic aid).
First trimester scan
It is a test performed at 11-13 weeks of pregnancy that can identify more than 85% of babies with Down syndrome and trisomy 18. The screening involves
- Ultrasonographic measurement of nuchal translucency (a skin fold behind the neck). A positive result is not diagnostic but indicates that an increased risk for a problem exists and that additional testing should be considered.
- Chorionic villous sampling in week 13 which is taking a sample of the chorionic villi of the placenta for genetic analysis under the guidance of ultrasound machines for safety.
Second trimester scan
It is a test performed at 14-17 weeks of pregnancy that can identify more than 85% of genetic abnormalities. The screening involves
- Biochemical analysis of maternal serum levels of beta-hCG (From the placenta), Free Estriol (From the fetus and placenta) and alphafeto protein (From the fetus)
- Ultrasound anomaly scan at 18-21 weeks
- Amniocentesis: It is performed at 16-20 weeks and it consists of a study of amniotic fluid after taking a sample of it by an aspiration needle guided through the abdomen by ultrasound to choose the safest and best location for aspiration.
Fetal inspection is done to check the normal growth of the fetus including its internal parts, the absence of any growth anomalies due to hereditary or genetic factors, absence of any disease in any organ of the fetus.
This is done by ultrasound which is a machine uses ultrasound waves to draw the internal organs of the mother and fetus on a display screen. There is two dimensional black and white ultrasonography, 3D ultrasonography which gives a more detailed 3 dimensional picture of the fetus, 4D ultrasonography which gives 3D picture in motion.
Ultrasound is used to
- Confirms presence of pregnancy and its location and accurate dating of pregnancy.
- Placental location and status.
- Cervical canal length measurement.
- Detailed scan at about 20 weeks to check any abnormalities in the baby’s structural development and growth.
- Doppler scanning for fetal growth retardation and repeated abortions.
- Amniotic fluid details.
- Baby presentation.
- Fetal sex.
- Biophysical profile by checking the baby respiration, muscle movement and tone.
- Expected date of delivery.
- Baby’s weight.
Your OBGYN does two roles, the first is inspecting your fetus and making sure it is growing well and without complications and the second is inspecting you to make sure that you are adapting well to pregnancy and interferes when he detects any problems. Your doctor will also provide a safe delivery plan and support during the post delivery period till you return back to your pre-pregnancy shape.
Good antenatal care has proven efficiency in reducing maternal and fetal problems and even death during pregnancy period or delivery period and after delivery period. In addition new techniques have been developed for prenatal testing that facilitated early detection of problems in the fetus which give parents time to check for medical or surgical treatment after birth and also to prevent the same problems from happening again in other pregnancies.
What does the doctor do in the first visit?
- Your doctor will start an antenatal care file for you
- He will ask you some medical and family history questions which have to be answered accurately like:
- Blood group and Rh factor?
- What illness did you have before?
- Did you do any operation before?
- Are you taking any medication?
- Were you pregnant before and how did it go?
- Is there any a familial disease or hereditary traits in your family.
- And some other questions which will help him have a general idea on any risk factor that might happen during your pregnancy period.
- Then he will ask you when was the first day of your last period?
- Your weight and blood pressure will be recorded in the first visit
- You will be asked to do some laboratory investigations (e.g. Blood Group, Rhesus factor, complete Blood picture, Blood Sugar, urine analysis, etc)
- The doctor will decide upon the first ultrasound scan which will be around the 7th week of pregnancy. Usually the scan will be through your abdomen and you should have a full bladder. Sometimes the scan will be done through the vagina but the ultra sonographer will talk to you about this if it proves necessary.
- He will give you instructions regarding nutrition, resting and exercising and will teach you the danger signs during pregnancy e.g. (vaginal spotting, fatigue, lower abdominal pain, severe vomiting or headache) any of which if you feel, you contact him at once. He will also explain all the fetal wellbeing exams that are performed.
- Your doctor arranges your visit schedules according to your case. You have to follow your doctor instructions well to deliver a healthy baby. You have to discuss with your doctor any changes that happen so that he can differentiate between normal and abnormal changes.
- Sometimes surgical interference occur (E.g. Cervical Cerculage)
What does the doctor do in every visit?
- Each visit you will be inspected for weight, blood pressure, general inspection with the addition of inspecting the baby inside you .The doctor makes sure that everything is all right and there are no signs of danger like e.g. pre eclampsia, gestational diabetes.
- Then he prescribes the appropriate nutrition for your pregnancy interval and exercises which are suitable for you.
