| Abstract | Background: There are no uniform professional guidelines regarding the use of umbilical artery velocimetry. The aim of this study was to find the value of this method in relation to other methods used for the evaluation of fetal condition, and which of these methods conelate signifcantly with the evaluation of the newbom's condition after birth. Methods: In 1193 women with threatened pregnancy due to intrauterine growth retardation, hypertension or proteinuria the following procedures were undertaken: calculation of the resistance index (RI) in the umbilical cord artery, cardiotocographic nonstress testing (NST), evaluation of amniotic fluid volume, fetal tone, fetal movement, fetal breathing movement and grading of placental maturity. Using the analysis of variance and conelation coeff cient, the conelation between the RI and other examinations performed was evaluated. To evaluate conelation between the RI and Apgar score after birth, the logistic regression >>step-by-step forward<< analysis was used. Results. In a threatened pregnancy a conelation between the RI and NST was found. Additionally, there exist significant conelations between the RI and fetal movement, as well as between the RI and fetal tone in the group of hypertensive women. In a threatened pregnancy no significant conrelation was found neither between the RI and fetal breathing movement, nor between the RI and placental maturity. For each group of threatened pregnancy a predictive model was formed. The results obtained by umbilical artery velocimetry did not fit into any of the predictive models for the assessment of neonatal condition after birth. Conclusion. In a threatened pregnancy there are signifcant corelations between RI and NST, amniotic fluid volume and fetal movement. The results of umbilical artery velocimetry do not conelate signif cantly with the Apgar score of the newbom at birth. | |
