ABSTRACT

Dilatation of the cervical canal is a routine act, performed in almost every gynecological department. Dangers that follow this intervention are always a challenge for human inventiveness. It is necessary to dilate the cervical canal with less risk, less pain, so that the treatment can be shorter, without leading to disturbance of the structure, or function of the cervix.
On the basis of positive and well-known experiences involved with process of dilatation, we have developed a system that consists of pneumatic dilator and a highly sophisticated aggregate, which supplies regulated air pressure for pneumatic dilator. This preliminary research was performed at the outpatient department of Clinic of Gynecology and Obstetrics in Kragujevac. The goal of this research was exactly, in vivo, through the artificial ending of pregnancy, to check original methods of dilatation of cervical canal with pneumatic dilator. One hundred women have been tested, and have been classified into two groups: In 50 patients, dilation of cervical canal has been done before curettage, with pneumatic dilator and in the second control group with also 50 patients, dilatation of cervical canal has been done with metal dilators by Hegar.
The cervical canal dilatation with pneumatic dilator was completely successful in all 50 women. During the testing there were no complications. The average time of dilatation was about 3 minutes. The uterine mouth is dilated fast and effectively. A Doctor can adapt the velocity and the rhythm of dilatation, and rearrange them to the resistance, which cervical mouth gives. The risk of indirect complications almost does not exist. Sterile dilator is made for one time use, so the risk of intrauterine infection is very small.

Key words: Cervix, cervical canal, pneumatic dilator, and abortion
