4. Infiltrate the skin puncture site with a small dose of an anesthetic solution using a very small gauge hypodermic needle.
5. Insert the Introducer through the site of the skin anesthetic infiltration.
6. Insert the Eldor Amniocentesis Needle through the Introducer into the uterus under ultrasound supervision.
7. Remove and discard the Obturator from the amniocentesis needle.
8. Attach the syringe to the amniocentesis needle.
9. Aspirate required volume of Amniotic Fluid. Discard the first few ml of amniotic fluid which are likeliest to be contaminated with maternal cells.
10. Remove the Eldor Amniocentesis Needle and the Introducer.
11. Clean the skin puncture site with an antiseptic solution.
12. Compress the puncture site and use an adhesive dressing.
