Clincal experience of fetal umbilical artery blood flow examination

Objective: To study the perinatal outcome in patients with abnormal umbilical artery blood flow and the relationship between the perinatal outcome and the efficacy of intrautery therapy. Methods: Patients whose umbilical artery blood flow exanlined before 34 gestational weeks during 2001.6 - 2003.12 were reviewed and analyzed. Results: (1)The rate of poor perinatal outcomes, especially the rate of fetal distress, in abnormal umbilical artery blood flow group was significantly hyigher than those in control groups (P0. 01).(2)The incidence of poor perinatal outcomes in patients whose umbilical artery blood flow turned to normal after intrautery therapy was signihcantly lower than those still abnormal. Conclusion: Umbilical artery blood flow examination can find fetal distress early in order to deal with in time to improve fetal well being. It can also observe the efficacy of the intrautery therapy
