摘　　要：目的探讨胎儿监护中胎心基线细变异减弱的原因及其与胎儿宫内储备能力的关系。方法选择门诊常规行无负荷胎心监护2次以上为无反应型(胎心基线细变异<6bpm和加速<15bpm)、入院诊断为胎儿宫内窘迫行剖宫产术的42例孕妇为观察组。另选择同期常规行无负荷胎心监护为有反应型(胎心基线细变异>6bpm和加速>15bpm)、因其它产科指征行剖宫产术的32例孕妇为对照组,对两组的病例资料进行分析。结果胎心基线细变异减弱因素中,观察组脐带因素异常占最大构成比(64.29%),与对照组比较差异有统计学意义(P<0.05)。结论对于孕晚期胎心监护基线细变异减弱合并脐带缠绕者,应尽快终止妊娠,可降低新生儿窒息的发生率及程度。Objective To study the cause of decrease of fetal monitoring fetal heart rate baseline thin varia-bility（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 cesare-an section due to fetal distress with the nonreaetive type of non-stress test（study group）. Thirty-two received cesarean section due to other obstetric indeafions with reactive type of non-stress test in the same period （ control group）. The clinical data was analyzed for the two groups,ineluding the causes of DFMV, the effect of DFMV on the fetal intrauter-ine stockpiling ability and the fetal prognosis. Results In the study group, the umbilical cord abnormal ratio was 64. 29%. There was statistcally significant （ P 〈 0. 05 ） compared with the control group. Conclusion For the preg-nant 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.
