| Abstract: | Objective: To predict fetus intrauterine hypoxia. Methods: Color doppler ultrasonography was performed in 147 cases of pregnant women. Results: S/D of fetal middle cerebral artery (MCA) blood flow wasless than 4, PI was less than 1. 4 and RI was less than 0. 6. S/D of umbilical artery (UMA) blood flow was more than 3, PI was more than 1. 7 and RI was more than 0. 8. When PI and RI MCA - UMA ratio was less than 1 indicated fetus intrauterine hypoxia. It was found that there was a significant difference in the frequency of fetal intrauterine hypoxia between the pregnancy - induced hypertension group or the intrauterine growth re-tardation group and the normal group (P< 0. 01 ). Conclusions: Monitoring MCA and UMA bldri flow resis- tance coud supply important information about fetal brain and fetus - plancenta circulation, and could predict fe- tus intrauterine hypoxia. |
