Abstract
Objective: To investigate the relationship between pregnancy outcome in older pregnant women and the uterine artery and fetal hemodynamic parameters in the third trimester.Methods: A total of 100 patients who received late pregnancy monitoring of uterine artery and fetal hemodynamics and had a delivery in our hospital were randomly selected as the subjects of this study.The hemodynamic parameters (PSV, EDV, RI, PI, S/D) of the uterine artery, umbilical artery and fetal middle cerebral artery in the third trimester between 36 elderly patients with normal pregnancy outcome (≥35 years old, observation group) and 32 patients with normal age of normal pregnancy (<35 years old, control group) were compared and analyzed.Besides, the hemodynamic parameters (PSV, EDV, RI, PI, S/D) of the uterine artery, umbilical artery and fetal middle cerebral artery in the third trimester between 32 elderly patients with abnormal pregnancy outcome (≥35 years old, observation group) and 36 elderly patients with normal pregnancy outcome (≥35 years old, control group) were also compared and analyzed.Results: Normal pregnancy outcomes in different age groups, the hemodynamic parameters of uterine artery, umbilical artery and fetal middle cerebral artery (PSV, EDV, RI, PI, S/D) were not significantly different (P≥0.05).In elder group with different pregnancy outcomes, PI value of fetal middle cerebral artery was statistically significant (P<0.05).There was no significant difference in the hemodynamic parameters (PSV, EDV, RI, PI, S/D) of uterine artery and umbilical artery (P≥0.05).Conclusions: Color Doppler ultrasonography to evaluate the PI value of fetal middle cerebral artery in older pregnant women has a certain reference value for judging whether there is hypoxia and distress and neonatal prognosis in the fetus, and can provide some reference information for clinicians to predict the pregnancy outcome of the older pregnant women.关键词
