Introduction. The parameters of blood flow in the mother-placenta-fetus system in the onset of labor are often changed depending by the presence of obstetric pathology, including the pathology of the placenta and its components. In connection with this, it was of interest to study the relationship between the amount of AF and the dopplerometry of blood flow in the uterine and umbilical arteries. Methods. The study was prospective of 100 parturients with the pathology of amniotic fluid. All pregnant women at the time of hospitalization were subjected to the ultrasound examination of fetus, placenta and umbilical cord and the amount of AF. Results. The results showed that the indexes of Doppler velocytometry curves during delivery were different according to the gestation term. Thus, in premature births, all indicators of dopplerometry were higher than in term births (p<0.01). In postterm births, the Doppler velocimetry indices exceeded the indices of premature and urgent births (p<0.05). Analysis of the relation between the dopplerometry data of the uterine artery and the amount of AF has shown that, in case of oligohydramnios, all the parameters of the blood flow velocity curves were significantly higher than those with the normal amount of fluid and polyhydramnios. The difference was significant (p<0.05). A similar trend was observed in the changed parameters of dopplerometry in the umbilical artery. All dopplerometry parameters were elevated for premature and postterm birth, as well as in case of oligoamnios. Major changes in Doppler velocytometry occurred in premature births at 28-31 weeks and in postterm after 42 weeks (p<0.001). Therefore, the correlation between AF volume, fetal heart rate and uterine and umbilical artery parameters is evident. Circulation resistance in these vessels increased as AF volume decreased. Conclusions. The term of gestation, amniotic fluid volume, cardiotocogram and dopplerometry parameters during delivery are in close relationships.
