This abortion technology is considered relatively safe, almost on a par with medication. Only failures in the form of incomplete abortion happen less with her. Another plus is a slightly larger allowable maximum interruption period. This is 7 obstetric weeks or 3 weeks from the onset of a delay in menstruation. In some cases, usually with a missed pregnancy, the procedure can be performed for longer periods.
Its advantage is that there is no need to expand the cervical canal with instruments and clean the uterine cavity with a curette. Accordingly, there is a small risk of inflammatory complications.
How everything goes. In a antenatal clinic or in a hospital, a woman is given local anesthesia. A thin disposable catheter is inserted into the uterus through the cervical canal, attached to a special apparatus with a container. After it is included in this container, the fetal egg, its membranes and endometrium are sucked off. The whole procedure takes about five minutes. If painful spasms of the uterus occur, intramuscular administration of an antispasmodic helps.
Termination of pregnancy by vacuum aspiration can have negative and very serious consequences, but rarely. This is perforation of the uterus, which can occur when measuring its length with a probe. And another complication is lethal, occurs due to a medical error - pneumoembolism. This is when not negative pressure is created in the uterine cavity, but positive. That is, air enters it, which instantly enters the bloodstream. Almost all newer vacuum aspirators are air protected.
