Cervical distraction

Distraction of the cervix is ​​the expansion of the cervical canal of the cervix through the use of expanding prostheses. Cervical distraction is considered the most effective method of preparing for childbirth in pregnant patients with a uterine scar. It leads to softening and shortening of the cervix due to improved blood supply.

Premature softening of the cervix occurs when dilatation (dilation) is used during preventive manipulations. Softening the cervical pharynx does not play any practical role in preparing a woman for childbirth, since it is most often associated with injuries and ruptures of the uterine scar or provokes placental abruption. In addition, the rapid preliminary expansion of the cervix initiates a premature uterine excitable block, which inhibits the maturation of labor. If the uterine wall is prematurely excited or there is no effect from prolongation, labor will not be activated even after cervical distraction is completed. Pathological symphysiolysis
