Vacuum( mini) abortion - Causes, symptoms and treatment. MF.
This way, you can successfully produce abortions in pregnancy for up to 10-12 weeks.
Vacuum curettes are metal tubes that resemble Gegar dilators, with a lateral opening at the rounded end. The hole has an oval shape. Each vacuum-curette is designed for an artificial abortion for a certain period of pregnancy. Vacuum curette # 6 perform an operation of artificial abortion during pregnancy for up to 6 weeks, a vacuum curette No. 9 for up to 8 weeks, a vacuum curette No. 10 for up to 10 weeks, and finally a vacuum curettage number 12 for pregnancy durationup to 12 weeks. Vacuum-curette is used only for suctioning the fetal egg from the uterine cavity.
The cervical canal is enlarged after careful anesthesia with lidocaine and anesthetizing the patient. The widening of the cervical canal is carried out by Gegar dilators, as with a conventional artificial abortion. The maximum expander must correspond to the size of the vacuum curette or be of a slightly larger diameter.
In the manufacture of an artificial abortion operation with a vacuum curette, manual and electric suction can be used. Vacuum curette is connected with suction by a dense rubber tube.
After the dilatation of the cervical canal, the vacuum curette of the corresponding number is introduced into the uterine cavity according to the same rules as the Gegar dilators. When its end reaches the bottom of the uterus, the electric pump is turned on( or the manual suction is activated).To destroy and remove the fetal egg, it is necessary to create a negative pressure in the vacuum curette of 0.4-0.6 kg / cm2.As soon as the needle of the vacuum gauge deviates to the desired digit, the curette should be withdrawn from the uterine cavity, so that the lower edge of its opening appears from the outer throat. At the same time, a stream of air bursting into the vacuum-curette entrains the tissues of the fetal egg, which enter the suction can via the tube.
To aspirate the remains of the fetal egg, the vacuum curette is again injected into the uterine cavity. Systematically, as with curettage, but absolutely not pressing the curette to the walls of the uterus, suck the mucous membrane of the uterus and the tissue of the fetal egg. Pressing the curette against the walls of the uterus, free from the parts of the fetal egg, with the revision of the uterus cavity, causes the same sensation as the touch of the uterine wall after scraping with a conventional curette.
With a vacuum-curette, the fetal egg is removed from the uterus within 0.5-1.5 minutes. The operation of vacuum-aspiration of the fetal egg has undoubted advantages before the operation of artificial abortion by scraping with an acute curette, which in almost all cases is damaged not only by the basal layer of the endometrium, but also by the muscular membrane of the uterine wall.
