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 demonstrate the significance of biophysical determination in the diagnosis of fetal distress. Methods: NST test was performed with fetal heart monitor, and FBM, FM, FT and AFV were observed with B ultrasound. The five indexes were combined to monitor intrauterine status. Results: Neonatal Apgar score, NST coincidence rate of 19.70%, while the biophysical phase was 62.12%, P <0.01; amniotic fluid NST coincidence rate was 34.0%, while the biophysical phase was 5 5. 30%, P <0. The coincidence rates of NST, FBM, FM and FT before and after birth were 33.33%, 65.15%, 75.76% and 82.58% respectively. Before and after biophysical application of NST abnormal cesarean section were 52.9% and 41.2%. CONCLUSION: Biophysical measurements can improve the diagnostic accuracy of fetal distress and reduce the blindness of obstetric treatment and the rate of cesarean section.
