【摘要】 目的 :比较单项新B超生物物理监测 (BPS)、单项胎心监护无负荷试验 (NST)与两者联合监护对过期妊娠的实用价值。方法 :对BPS(即胎儿呼吸运动、胎动、肌张力、羊水量及NST) 5项进行改良 :去NST为单项监测 ,其余 4项加胎盘分级称新BPS ,两项联合监测称改良BPS ,共监测过期妊娠 6 8例。结果 :联合监测双项异常的新生儿窒息数和羊水Ⅲ°粪染数明显高于联合监护均正常和单项监测异常者 (P <0 .0 0 5 )。结论 :应用改良BPS联合监测胎儿情况明显优于单项监测。更多还原

【Abstract】 Objective:To compare the value of single B ultrasound,non stimulation test(NST) and united surveillance used in prolonged pregnancy.Methods:The five items(i.e.:fetal breathing movement,fetal movement,muscle tension,amniotic fluid volume and NST) of B ultrasound biophysical surveillance(BPS) were altered as follows:NST was treated as a solo test,the other four items associated with placenta classification were called new BPS and the new BPS united with NST called improved BPS.Sixty eight cases of prolonged pregnancy were monitored.Results:The number of neonatal asphyxia and Ⅲ° faecal contamination of amniotic fluid in the group with both items abnormal by united surveillance was much higher than that in the group with both items normal or only one items abnormal( P <0.005).Conclusions:The improved BPS is obviously better than solo surveillance.更多还原
