胎膜早破后残余羊水量对母婴的影响

目的探讨胎膜早破后残余羊水量对母婴的影响。方法对397例胎膜早破孕妇的临床资料进行回顾性分析，根据残余羊水指数（AFI）的多少分成3组，即羊水正常组（80mm〈AFI≤180mm），羊水偏少组（50mm（AFI≤80mm），羊水过少组（AFI≤50ram），对不同残余羊水指数孕妇的分娩方式及胎儿窘迫、宫内感染率、新生儿发病率进行比较。结果羊水过少组较羊水偏少组及羊水正常组剖宫产率、胎儿窘迫发生率、胎儿宫内感染率、新生儿发病率高，差异有统计学意义。结论胎膜早破后残余羊水量过少会促使宫内感染率增加，影响胎儿、新生儿的生命安全，残余羊水指数可作为临床监测胎儿宫内安危的指标，予合理干预，选择正确的分娩方式，提高产科质量。

Effect of residual amount of amniotic fluid after premature rupture of membranes on mother and infant

Objective To explore the effect of residual amount of amniotic fluid after premature rupture of membranes on mother and infant. Method Take retrospective analysis on clinical data of 397 pregnant women with premature rupture of membrane. Divide pregnant women into 3 groups according to residual amount of amniotic fluid index （AFI）, namely normal amniotic fluid group （80 mm〈AFI≤180 mm）, less amniotic fluid group （50 mm〈AFI≤80 mm） and lacking amniotic fluid group （AFI≤50 mm）. Analyze the delivering method, fetal distress, intrauterine infection rate and neonatal morbidity of pregnant women with different AFI. Result Cesarean section rate, fetal distress, intrauterine infection rate and neonatal morbidity of lacking amniotic fluid group is obviously higher than those of less amniotic fluid group and normal amniotic fluid group. The difference is significant. Conclusion To little amniotic fluid after premature rupture of membranes will increase the incidence of intrauterine infection and affect the safety of fetus and newborns. AFI can be a clinical index of monitoring fetus＇ safety in uterus. Giving prosperous intervention, selecting right delivering method can improve the quality of obstetric nursing care.
