Abortion after 12 weeks

Abortion is less commonly performed after 12 weeks because of increased risks to the woman. After 12 weeks the foetus is so large that a method other than vacuum or suction aspiration is used. From 12 to 18 weeks the procedure is called dilation and evacuation. This is nearly always performed under general anaesthetic.

The woman presents at the clinic sometime before the procedure and a substance is used to soften and dilate the cervix. Later that day or the next day instruments are used to remove the foetus. A combination of forceps, suction and curettage is often used.

For an abortion later in the pregnancy (18 to 26 weeks) prostoglandins are used. They are inserted into the vagina or injected into the uterus. This induces uterine contractions and causes the cervix to dilate and the birth process to begin.

The procedure may take some time and the woman needs to be awake to deliver the foetus. Some choose to have an Epidural Block. After this procedure some women require a curettage which is performed with sedation.

It is the large amount of Prostoglandins used that causes distress to the foetus and subsequently it dies either before or during birth or soon afterwards.

Although some women appear to experience minimal problems, abortion may be followed by serious long term physical and psychological side effects.
