 There are many methods of abortion. Chosen procedure depends largely upon the stage of gestation and the size of the unborn child.
The most common method is suction-aspiration or vacuum abortion. It conducts in the first 15 weeks. Manual vacuum aspiration, or MVA abortion, means removing the fetus or embryo by suction using of manual syringe, whereas the Elective vacuum aspiration, or EVA abortion method uses an electric pump. During the first 12 weeks of pregnancy suction or vacuum aspiration is the most suitable method. General or local anesthesia is given to the mother in order to dilate her cervix. A suction current (empty tube with a knife-edged tip) uses. It inserts into the womb. Then this instrument connects to a vacuum machine by a transparent tube. The vacuum suction is in 29 times more powerful than a domestic vacuum cleaner. It tears the fetus and placenta into small peaces which are sucked through the tube into a bottle and discard. These techniques are equal, but their difference only in the using mechanism to apply suction. These methods sometimes refer to as STOP (Suction or Surgical Termination of Pregnancy).
In period from the 6th until 16th week of pregnancy, such procedure as dilation and curettage or ( D & C ) is usually conducted. It is used in an effort to examine the uterine lining in a subject of possible malignancy, to investigate the abnormal bleeding, or to conduct an abortion. During scraping the walls of the uterus are undergo the cleaning with a curette.
In order of this procedure, cervical methods of abortion are used to dilate the uterus. One of the most common is an insertion of different surgical instruments (different kinds of dilators and various metallic bent instruments) into the cervix to enlarge it. This equipment is used to open the cervix for further accommodation of abortion instruments in it. Such unnatural forceful stretching of the cervix can cause serious physical injury.
A dilation and curettage procedure often requires general anesthesia, that is why it must perform only in a clinic or hospital. There is a big possibility of appearing some complications such as cervical injuries and reaction to the anesthesia. After the development of vacuum aspiration, the use of dilation and curettage has declined.
