How to Prepare for an Amniocentesis

It is natural to feel fear before amniocentesis. However, many women say they experience little or no pain during the procedure. And the results of an amniocentesis will do a lot to allay fears later in the pregnancy.


Step1
Prepare to have amniocentesis between the 15th and 20th weeks of your pregnancy.


Step2
Wear loose-fitting clothes the morning of your procedure.


Step3
Eat a light breakfast.


Step4
Drink 48-64 ounces of fluid before your amniocentesis, if specified by your doctor.


Step5
Hold your bladder until your doctor or ultrasound technician instructs you to urinate. Usually, an ultrasound is done to locate the placenta before inserting the needle. (See "How To Get An Ultrasound.")


Step6
Understand that the procedure will take 20 to 45 minutes.


Step7
Sign a consent form.


Step8
Lie back on the procedure table. Fold your hands behind your head. Take several slow, deep breaths.


Step9
Allow the doctor to cleanse your abdomen with alcohol or betadine.


Step10
Take a slow, deep breath as the doctor inserts a needle through your abdomen to remove about a tablespoon of amniotic fluid. You may feel a brief stinging sensation.
