METHOD FOR PREDICTING VAGINAL DELIVERY IN PREGNANT WOMEN AFTER ONE CAESAREAN SECTION PERFORMED BY A TRANSVERSE INCISION IN THE LOWER SEGMENT OF THE UTERUS Russian patent published in 2023 - IPC A61B5/107 A61B8/06 

FIELD: medicine; operative obstetrics.

SUBSTANCE: invention can be used to predict vaginal delivery in pregnant women with a uterine scar after one caesarean section performed by a transverse incision in the lower uterine segment. It is found out if a pregnant woman with the onset of regular labor had a history of vaginal delivery before or after one cesarean section, the degree of cervical dilatation is assessed, and the minimum thickness of the lower uterine segment is measured by ultrasound. Each indicator is evaluated in points according to the developed scale. Then the prognostic index p is calculated using a mathematical formula. At p values less than 38%, a low probability of delivery by caesarean section and a high probability of a favorable outcome of labor through the natural birth canal are predicted, and vaginal delivery is continued. When the p value is greater than or equal to 38%, a high probability of delivery by caesarean section is predicted and a caesarean section is performed.

EFFECT: invention makes it possible to identify women in labor belonging to a high risk group for the development of threatening uterine rupture, and timely select the necessary tactics for conducting childbirth, reducing the risks of maternal and perinatal complications.
