Procedure for Amniotic Fluid Analysis

Procedure

A consent form should signed
Food and fluids are not restricted
Have a client to void before the procedure to prevent puncturing the bladder and aspirating urine
Cleanse the suprapubic area with an antiseptic such as povidone-iodine (betadine).
A local anesthetic is injected at the site for amniocentesis
The placenta and fetus should be located by ultrasound or manually (fetus only).
A 22 gauge spinal needle with sylet is inserted through the skin to the amniotic cavity
5-15 mL amniotic fluid is aspirated. Apply a small dressing to the needle insertion site
The procedure takes approximately 30 minutes.

Factors Affecting Diagnostic Results

A traumatic amniotic tap may produce blood in the amniotic fluid.

Nursing Implications

Recognize when amniocentesis for amniotic fluid analysis is indicated (e.g. with a familial history of sex- linked, genetic or chromosomal disorders; with a history of previous miscarriages; and in advanced maternal age (>35-years-old). It is not a screening test
Be supportive of the women and her partner. Be a good listener. Allow them time to ask questions and to express any concerns. Refer questions you cannot answer to the appropriate health professionals
Be sure that the client urinates before the test and that the consent form is signed.

Client Teaching

Inform the client that normal results do not guarantee a normal infant, nor do they always predict sex correctly. The health care provider should tell the woman of potential risks
Instruct the client to notify the healthcare provider immediately of any of the following: bleeding or leaking fluid from the vagina, abdominal pain or cramping, chills and fever or lack of fetal movement
Encourage the women and her partner to seek genetic counseling especially if a chromosomal abnormality has been detected.
