Comparison between fetal umbilical cord blood flow parameters and middle cerebral artery peak systolic velocity in amniotic infusion therapy for oligohydramnios
Abstract：Objective To compare the changes of umbilical cord blood flow parameters and the middle cerebral artery peak systolic velocity before and after the amniotic infusion therapy,and to explore the effect of amniotic infusion therapy on fetal umbilical cord blood flow and middle cerebral artery peak systolic velocity(MCA-PSV) in oligohydramnios. Methods 18 pregnant women who had been diagnosed with oligohydramnios by sonography between 22 and 33 gestational weeks received amniotic infusion in our department from January 2014 to December 2016. The amniotic fluid index(AI), umbilical blood flow parameters such as S/D,RI and middle cerebral artery peak systolic velocity(MCA-PSV) were recorded and compared before and after amniotic infusion. Results The amniotic fluid index was improved significantly(P < 0. 01), S/D and RI were both decreased significantly(P < 0. 01,P < 0. 05) after amniotic infusion,but MCA-PSV was not markedly changed. Conclusion Amniotic infusion therapy can improve amniotic fluid index and umbilical artery flow parameters in a short period,but has no effect on the peak systolic velocity of the middle cerebral artery.
