摘要
Objective: The purpose of this study was to investigate the relationship between pregnancy outcome in older pregnant women and the uterine artery and fetal hemodynamic parameters in the third trimester. Methods: Randomized selection of 100 patients in our hospital delivery and late pregnancy monitoring of uterine artery and fetal hemodynamics in patients. (1) There were compared and analyzed 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). (2) There were compared and analyzed the hemodynamic parameters of the uterine artery, umbilical artery and fetal middle cerebral artery in the third trimester between 32 elderly patients with abnormal pregnancy outcome and 36 elderly patients with normal pregnancy outcome. Results: (1) Normal pregnancy outcomes in different age groups, the hemodynamic parameters of uterine artery, umbilical artery and fetal middle cerebral artery were not significantly different. (2) The high age group had different pregnancy outcomes,Fetal middle cerebral artery PI was statistically significant, there was no significant difference in Uterine artery and umbilical artery of the hemodynamic parameters. Conclusion: Color Doppler ultrasonography to evaluate the PI value of fetal middle cerebral artery in older pregnant women has a certain reference value to judge whether there is hypoxia and distress and neonatal prognosis in the fetus, and to provide some reference information for clinicians to predict the pregnancy outcome of the older pregnant women.
