摘要
目的通过研究低危孕妇临界性羊水指数(AFI)与不良妊娠结局间的关系,探讨AFI更合理的诊断标准,为临床决策提供重要依据。方法选取2016年12月至2018年12月在西安交通大学第一附属医院和西安高新医院住院的单胎足月待产孕妇(孕周为37~<42周)共386例为研究对象,根据AFI检测结果分为临界组(AFI为5.1~8.0cm)96例,正常组(AFI为8.1~24.0cm)290例,观察比较两组孕妇的羊水胎粪污染、低Apgar评分、胎儿窘迫所致剖宫产、足月小样儿、入住新生儿重症监护病房(NICU)等指标的发生率。结果临界组与对照组的羊水胎粪污染、低Apgar评分、胎儿窘迫所致剖宫产的发生率分别为13.54%、0、7.29%与18.62%、0.69%、8.28%,临界组均低于对照组,但差异均无统计学意义(χ^2值分别为1.297、0.666、0.095,均P>0.05);临界组与对照组的足月小样儿、入住新生儿NICU的发生率分别为2.08%、14.58%与0.34%、11.38%,临界组均高于对照组,但差异均无统计学意义(χ^2值分别为2.827、0.692,均P>0.05)。结论低危孕妇妊娠晚期临界性AFI可能不会增加不良妊娠结局的风险。
Objective To investigate correlation between borderline amniotic fluid index(AFI)and adverse pregnancy outcome in low-risk pregnant women,and to determine more reasonable diagnosis criteria of AFI,so as to provide important basis for clinical decision-making.Methods A total of 386low-risk pregnant women with singleton term pregnancy(37W≤GA<42W)who admitted to The First Affiliated Hospital of Medical College,Xi'an Jiaotong University and Xi'an Gaoxin Hospital in a period from December 2016to December 2018were selected as study subjects.According to detection result of AFI,96pregnant women with borderline AFI(5.1<AFI≤8.0)were divided into borderline AFI group and 290pregnant women with normal AFI(24.0<AFI>8.1)were divided into normal AFI group.The incidences of meconium-stained amniotic fluid,low Apgar score,cesarean delivery due to fetal distress,small for date infant,NICU admission were compared between the borderline and normal AFI groups.Results The demographic and obstetric characteristics were similar in each groups.The incidences of meconium-stained amniotic fluid,low Apgar score and cesarean delivery due to fetal distress in the borderline AFI group(13.54%,0.00%and 7.29%respectively)were lower than those in the normal AFI group(18.62%,0.69%and 8.28%respectively),but there were no significant differences between the two groups(χ^2=1.297,0.666and 0.095respectively,all P>0.05).The rates of the small for date infant and NICU admission in the borderline AFI group(2.08%and 14.58%)were higher than the normal AFI group(0.34%and 11.38%respectively),but there were no significant differences between the two groups(χ^2=2.827and 0.692respectively,both P>0.05).Conclusion Borderline AFI of low-risk pregnant women in late pregnancy does not increase risk of adverse pregnancy outcomes.
