METHOD FOR PREDICTION OF TIMELY DELIVERY WITH INTRAUTERINE GROWTH RETARDATION Russian patent published in 2020 - IPC A61B8/00 A61B8/06 

Abstract RU 2736161 C1

FIELD: medicine; obstetrics.

SUBSTANCE: invention can be used for diagnosing intrauterine growth retardation (IUGR) at various stages of pregnancy. Resistance indices (RI) are determined in Doppler examination. At 18–21 weeks of pregnancy, the left and right uterine artery RI are determined, and the umbilical artery RI. If the left and/or right uterine artery RI is increased to 0.55 and higher or the umbilical artery RI up to 0.67 and higher, the uteroplacental blood circulation impairment (UPBCI) of the first degree is diagnosed. If the left and/or right uterine artery RI is increased to 0.55 and higher, and the umbilical arteries to 0.67 and higher, the second-degree UPBCI is diagnosed, starting from 32nd week at the first degree of the UPBCI or from 28th week of the second degree of UPBCI, the placental maturity, the degree of maturity of the fetus and fetal growth are monitored at least once every two weeks. At 2-week delay of fetus growth and achievement of the third degree of maturity of placenta or the second degree of maturity of fetus lungs delivery is performed. In the case of the second-degree IUGR, the Cesarean section is prescribed, while the first-degree IUGR involves the conservative delivery.

EFFECT: method enables reducing a risk of unfavorable outcomes of labor due to more accurate prediction of intrauterine growth retardation and determining an optimal length of delivery.
