入室试验对预测分娩及围产儿结局的临床意义

目的探讨入室试验对预测分娩及围产儿结局的临床应用价值。方法选择2009年2月—2011年6月在浙江大学医学院附属妇产科医院分娩室进行入室试验的单胎孕妇825人,其结果反应型为正常组,可疑或异常型为异常组,随访两组的分娩及围产儿结局。结果正常组中自然分娩率和剖宫产率分别为62.51%和37.16%,而异常组分别为40.10%和59.34%,两组分娩方式比较差异有统计学意义(P0.01)。异常组中胎儿窘迫、新生儿窒息和新生儿并发症发生率分别为44.50%、14.83%和33.51%,明显高于正常组的23.32%、0%和2.17%,差异有统计学意义(P0.05)。异常组中胎膜早破、脐带因素、胎盘因素和绒毛膜炎发生率分别为73.63%、37.36%、9.34%和7.14%,明显高于正常组的30.94%、20.83%、0.62%和0.15%,两组比较差异有统计学意义(P0.05)。结论入室试验是临产后了解胎儿-胎盘储备功能,评估胎儿宫内状况的有效监护手段。

Clinical Significance of Admission Test in Predicting Delivery and Perinatal Outcomes

Objective To evaluate the clinical value of admission test in predicting delivery and perinatal outcomes.Methods In Women’ s Hospital of Zhejiang University School of Medicine,825 antepartum singleton pregnant women were selected to conduct the admission test from February 2009 to June 2011.Reactive results were the normal group while suspected or abnormal react were the abnormal group.The delivery and perinatal outcomes of the two groups were followed up.Results The difference in the rate of natural delivery and cesarean section was significant between the normal group(62.51% and 37.16%,respectively) and the abnormal group(40.10% and 59.34% respectively).The rate of fetal distress,neonatal asphyxia and neonatal complications in abnormal group(44.50%,14.83% and 33.51% respectively) were higher than the normal group(23.32%,0% and 2.17% respectively),and the difference between the two groups was statistically significant(P <0.05).The incidence rate of premature rupture of membranes,umbilical cord factor,placenta factor and chorioamnionitis in the abnormal group(73.63%,37.36%,9.34%,and 7.14%,respectively) was higher than those in the normal group(30.94%,20.83%,0.62% and 0.15%,respectively).The difference were statistically significant between the two groups(P <0.05).Conclusion The admission test is an effective method to understand the placenta function and fetal intrauterine state during labor.
