The cause analysis of decrease of fetal monitoring fetal heart rate baseline thin variability

Objective To study the cause of decrease of fetal monitoring fetal heart rate baseline thin variability(DFMV)and the relationship between DFMV and fetal intrauterine stockpiling ability.Methods The clinical data of 74 cases of late pregnancy was chosen from obstetric clinic of them,forty-two pregnant women received cesarean section due to fetal distress with the nonreactive type of non-stress test(study group).Thirty-two received cesarean section due to other obstetric indcafions with reactive type of non-stress test in the same period(control group).The clinical data was analyzed for the two groups,including the causes of DFMV,the effect of DFMV on the fetal intrauterine stockpiling ability and the fetal prognosis.Results In the study group,the umbilical cord abnormal ratio was 64.29%.There was statistcally significant(P0.05) compared with the control group.Conclusion For the pregnant women with DFMV and abnormal umbilical cord,terminating pregnancy in time during late pregnancy period would lower the newborn distress rate and the asphyxial degree.
