胎儿生物物理相测定132例临床分析

Biophysical Score: Clinical Analysis in 132 Feti

目的 :论证生物物理相测定对胎儿宫内窘迫诊断的意义。方法 :用胎心监护仪作NST试验 ,用B超观察FBM、FM、FT、AFV ,该 5个指标联合用于监测胎儿宫内状态。结果 :新生儿Apgar评分 ,NST符合率为 19.70 % ,而生物物理相为 6 2 .12 % ,P <0 .0 1;羊水变化NST符合率为 34.0 9% ,而生物物理相为 5 5 .30 % ,P <0 .0 1。胎婴儿出生前后的NST、FBM、FM、FT缺氧符合率顺序分别为 33 .33%、6 5 .15 %、75 .76 %、82 .5 8%。生物物理相应用前后NST异常剖宫产分别为 5 2 .9%和 41.2 %。结论 :生物物理相测定能提高胎儿宫内窘迫诊断的准确性 ,减少产科处理的盲目性和剖宫产率。

Objective: To evaluate the value of biophysical score in the diagnosis of fetal distress. Methods: 5 parameters including NST, FBM, FM, FT, AFV were applied to biophysical score to monitor fetal situation. Results: There was significant difference between biophysical score and NST in consistent with the neonatal Apgar′s value (62.12%, 20.27%, P<0.01) and with the nature of amniotic fluid (55.30%, 34.09%, P< 0.01) . In regard to diagnosis of fetal distress, coincident rate of NST was 33.33%, FBM 65.15%, FM 75.76%, FT 82.58% in the diagnosis of distress. Rates of cesarean section were 41.2% and 52.9% respectively owing to abnormal biophysical score and abnormal NST. Conclusions: Biophysical score raises the degree of accuracy in diagnosis of fetal distress and reduces the unsuitable obstetric management and the rate of cesarean section.
