Current Abortion Procedures

Vacuum Aspiration (Suction Curettage)

Vacuum aspiration, sometimes referred to as suction curettage, is an abortion that is performed during the first trimester (first three months of pregnancy). An ultrasound is done before the procedure to determine the exact location of the embryo. In a vacuum aspiration abortion, the cervix, or opening of the uterus, is dilated or stretched. This allows the physician to insert a small plastic tube, called a cannula, into the uterus. The cannula is attached to a suction tube and machine or, occasionally, in early pregnancy to a large special syringe that is used to apply manual suction. As the suction cannula is moved throughout the uterus, it scrapes and removes by suction the soft and flexible fetus along with the placenta and other tissues and fluids of pregnancy. Vacuum aspiration is generally performed in a clinic under local anesthesia.

Medical Abortion (Mifepristone and Misoprostol)

A non-surgical abortion procedure using the drugs, Mifepristone and Misoprostol, may be used by women who are in the first 10 weeks of pregnancy (by LMP). This procedure usually
allows a woman to have the abortion at home. An ultrasound is done before the procedure to determine implantation of the embryo. Then a dose of 200 mg of Mifepristone is given at the clinic. She is then given Misoprostol tablets to take anytime between six and 24 hours later at home. Misoprostol causes the uterus to contract, bleed, and expel the pregnancy. A follow-up examination is necessary to determine if the abortion was complete. In cases where the pregnancy continues, vacuum aspiration is recommended because of the possibility of birth defects should the woman complete her pregnancy.

Dilation & Evacuation (D & E)

Dilation & Evacuation procedures are the most common procedure performed in the second trimester of pregnancy (months 4-6). An ultrasound is done before the procedure to determine the exact location of the fetus and placenta. With a D & E procedure, the cervix must be dilated before the procedure. This can be done with either medications, a natural or synthetic substance
inserted into the cervix that slowly widens the cervix as it swells with moisture, or a combination of the two. Sometimes preparing the cervix must be done the day before the D & E procedure. When the opening of the cervix is sufficient, the suction tube or cannula is inserted into the uterus. The suction tube or cannula removes by suction the fluid, placenta, and possibly other pregnancy tissues. The procedure is carried out using ultrasound guidance to assure safety. Forceps are used to remove larger fetal parts and parts of the placenta. The procedure is performed under sedation, often a combination of local anesthesia as well as intravenous medication, and can be done in a clinic.

Prostaglandins

An abortion procedure that is sometimes used during the second trimester involves prostaglandin, a natural hormone and other medications that induces labor. Prostaglandin is generally placed, in suppository form, into the vagina. Typically, prostaglandin causes the woman to go into labor and deliver the fetus and other tissues of pregnancy within 24 to 36 hours. This procedure is usually performed in a hospital.
