Extra-amniotic administration

Extra-amniotic administration (pronounced: ek-struh am-nee-ot-ik ad-min-uh-stray-shuhn) is a medical procedure that involves the delivery of medication or other substances directly into the extra-amniotic space, which is the area between the amnion (the innermost layer of the fetal membrane) and the chorion (the outermost layer of the fetal membrane).

Etymology

The term "extra-amniotic administration" is derived from the Latin "extra" meaning outside, "amnion" referring to the innermost layer of the fetal membrane, and "administration" from the Latin "administratio" meaning management or control.

Procedure

In an extra-amniotic administration, a thin catheter is inserted through the cervix into the extra-amniotic space. The medication or substance is then delivered through this catheter. This procedure is often used to administer medications such as prostaglandins for labor induction or termination of pregnancy. It can also be used for the administration of other substances for research or therapeutic purposes.

Related Terms

• Amnion: The innermost layer of the fetal membrane, which contains the amniotic fluid and the fetus.
• Chorion: The outermost layer of the fetal membrane, which is in contact with the maternal tissues and contributes to the formation of the placenta.
• Prostaglandins: A group of hormone-like substances that play a role in a wide range of body functions such as the contraction and relaxation of smooth muscle, the dilation and constriction of blood vessels, control of blood pressure, and modulation of inflammation.

Risks and Complications

Like any medical procedure, extra-amniotic administration carries potential risks and complications. These may include infection, premature rupture of membranes, and unintended induction of labor. It is important for healthcare providers to discuss these risks with patients prior to the procedure.
