The abdominal muscles support the trunk, allow movement and hold organs in place by regulating internal abdominal pressure.
The type of pain felt in the abdomen can vary greatly. Children may feel stomach pain for a range of reasons and may need treatment. Content on this website is provided for information purposes only.

Problems detected by amniocentesis Amniocentesis can detect a number of chromosomal and other birth abnormalities in a developing fetus. These include: Down syndrome Neural tube defects, such as spina bifida Genetic disorders — amniotic fluid samples can be DNA tested to identify a range of genetic disorders, such as cystic fibrosis and fragile X syndrome. Women who may benefit from amniocentesis As a woman grows older, the risk of having a child with Down syndrome begins to increase significantly — from about one in 2, at age 20 years to one in at 40 years.
Pregnant women who may be candidates for amniocentesis include: Women over the age of 40 years Victorian women aged 37 years and over are routinely offered this test Women with a family history of chromosomal abnormalities, such as Down syndrome Women who have already had children with chromosomal abnormalities Women known to be carriers of genetic disorders Women with partners who have a family history of a genetic disorder or chromosomal abnormality Women who return an abnormal 'serum screen' blood test or ultrasound examination result.
The amniocentesis procedure Before having amniocentesis, it is usual for the woman and her partner to be counselled on the risks of the procedure. Steps involved in amniocentesis: The woman lies down and the position of the fetus and the placenta are determined by an ultrasound scan.
Amniocentesis is associated with a small risk of miscarriage. With our experience , the risk of miscarriage is approximately 1 in every procedures.

Maternal Fetal Medicine Amniocentesis Amniocentesis is a procedure that, under ultrasound guidance , a small amount of amniotic fluid is withdrawn with a needle from the amniotic sac, the self-contained fluid-filled membrane surrounding the baby.
Amniocentesis Aftercare In general, you should be able to resume most daily activities after amniocentesis. The following are general guidelines for follow-up care: For 24 hours after the procedure, please stay off your feet as much as possible. Amniotic fluid is the fluid that surrounds and protects a baby during pregnancy. This fluid contains fetal cells and various proteins. Although amniocentesis can provide valuable information about your baby's health, it's important to understand the risks of amniocentesis — and be prepared for the results.
Genetic amniocentesis can provide information about your baby's genetic makeup. Generally, genetic amniocentesis is offered when the test results might have a significant impact on the management of the pregnancy or your desire to continue the pregnancy. Genetic amniocentesis is usually done between weeks 15 and 20 of pregnancy. Amniocentesis done before week 15 of pregnancy has been associated with a higher rate of complications. Fetal lung maturity amniocentesis can determine whether a baby's lungs are ready for birth.
This type of amniocentesis is done only if early delivery — either through induction or C-section — is being considered to prevent pregnancy complications for the mother in a nonemergency situation.
It's usually done between 32 and 39 weeks of pregnancy. Earlier than 32 weeks, a baby's lungs are unlikely to be fully developed. Amniocentesis isn't appropriate for everyone, however.
These infections can be transferred to your baby during amniocentesis. Remember, genetic amniocentesis is typically offered when the test results might have a significant impact on management of the pregnancy. Ultimately, the decision to have genetic amniocentesis is up to you. Your health care provider or genetic counselor can help you weigh all the factors in the decision. If you're having amniocentesis done before week 20 of pregnancy, it might be helpful to have your bladder full during the procedure to support the uterus.
Drink plenty of fluids before your appointment. After 20 weeks of pregnancy, your bladder should be empty during amniocentesis to minimize the chance of puncture. Your health care provider will explain the procedure and ask you to sign a consent form before the procedure begins. Consider asking someone to accompany you to the appointment for emotional support or to drive you home afterward.
First, your health care provider will use ultrasound to determine the baby's exact location in your uterus. You'll lie on your back on an exam table and expose your abdomen.
