Clinical Analysis of Abnormal Umbilical S/D Ratios in 108 Cases

Objective: Application of detection of fetal cord blood flow was measured umbilical artery S / D value of umbilical blood flow caused S / D ratio increased the main Reason.Methods: A total of 1919 pregnant women with 28 to 42 weeks of pregnancy,who were examined the umbilical artery blood flow during September 2009 ~ December 2010 in our hospital.Results: 108 cases of abnormal umbilical cord factor,fetal distress,oligohydramnios and the incidence of PIH was significantly higher than the normal group,the difference was significant(P0.05).Conclusion: Umbilical artery S / D ratio increased to enable the early warning and detection of fetal hypoxia,early clinical intervention and treatment measures to improve the quality of perinatal care.
