Abortion Methods

Vacuum Aspiration Method

In vacuum aspiration abortion:

The patient lies on the gynaecological table in the lithotomy position. In order to view the cervix, a disposable, sterile vaginal speculum is inserted in the appropriate size for the patient.

The cervix is ​​cleaned with an antiseptic solution to reduce the risk of infection. Afterwards, the cervix is ​​fixed with an instrument called tenaculum (single tooth). By pulling the cervix slightly by means of the tenaculum instrument,  the uterus is given a suitable position.

Afterwards, the uterine cavity is reached by passing through the cervix with the help of a thin plastic cannula. The size of the plastic cannula used changes depending on the gestational age. As the gestational age progresses, the thickness of the cannula used increases. In general, cannulas in size 5 or 6 suffice for vacuum aspiration abortion. The cannulas used are sterile and disposable.

After reaching the uterine cavity with the plastic cannula, the karman injector, which is set up in a way to provide negative pressure, is attached to the outer end of the plastic cannula. The button on the injector is turned on and the pregnancy tissues in the uterus is evacuated by means of the negative pressure. This process is repeated until it is ensured that there are no tissues left in the uterus.

After the procedure is completed the cervix is sanitised again with an antiseptic solution. The instruments are removed, the cannulas connected to the karman injector are thrown away, they are not used in another patient. All of the abortion procedures mentioned above take 5-10 minutes in total.

In some cases, the plastic cannula may not pass through the cervix due to its narrowness. In such situations, the cervix is slightly widened with the help of thin bougies. It is necessary to be very careful and attentive while performing this procedure called dilatation. Since uterine perforation, which is one of the complications of abortion, mostly occurs during this dilatation procedure. However, in general, in 90-95% of patients, the uterine cavity can be reached and the fetus can be taken without a need for dilatation (expansion) procedure.
