摘要
目的 探讨孕晚期羊水量过少对妊娠方式及结局的影响.方法 选取2016年3月至2017年12月介休市妇幼保健计划生育服务中心住院分娩的孕晚期羊水量减少孕妇46例为观察组,并选取同期46例羊水量正常的孕晚期孕妇为对照组,比较两组无应激试验（NST）评分、收缩期/舒张期（S/D）比值、分娩方式、妊娠结局,并比较不同程度羊水量减少者妊娠结局及分娩方式.结果 观察组S/D比值≥3.0所占比例高于对照组（P〈0.05）;两组NST评分比较差异未见统计学意义（P〉0.05）;观察组剖宫产率高于对照组,且羊水量过少者剖宫产率高于羊水量减少者（P〈0.05）;观察组羊水Ⅲ度污染、新生儿窒息及出生低体质量儿所占比例高于对照组（P〈0.05）;与羊水量偏少患者比较,羊水量过少患者羊水Ⅲ度污染及出生低体质量儿发生率较高（P〈0.05）.结论 孕晚期羊水量减少将增加剖宫产率及出生低体质量儿发生率,且随着羊水量减少,其发生率不断升高.
Objective To investigate the influence of oligohydramnios on the mode and outcome of pregnancy in late preterm .Methods Forty -six pregnant women with reduction of amniotic fluid volume in the late trimester of pregnancy who gave birth in Jiexiu Maternal and Child Health Care Planning Service Center from March 2016 to December 2017 were selected as observation group , and 46 cases of pregnant women with normal amniotic fluid volume in the same period were selected as control group.Non-stress test （ NST） score, the ratio of systolic to diastolic （ S/D）, delivery mode, and pregnancy outcome were compared between the two groups .Pregnancy outcome and delivery mode were compared among pregnant women with different degrees of amniotic fluid reduction .Results The ratio of S/D≥3.0 in observation group was higher than that in control group （ P〈0.05 ） , there was no significant difference in NST score between the two groups （ P〉0.05 ）;the rate of caesarean section in observation group was significantly higher than that in control group , and the cesarean section rate in pregnant women with a borderline amniotic fluid was higher than that in pregnant women with oligohydramnios （ P〈0.05 ） .The proportion of amniotic fluid grade Ⅲpollution , neonatal asphyxia and low weight infants of observation group was significantly higher than that of control group （ P〈0.05 ） . Compared with the women with a borderline amniotic fluid , the incidence of amniotic fluid grade Ⅲpollution and rate of low weight infants were higher in pregnant women with oligohydramnios （ P〈0.05 ） . Conclusions The decrease of amniotic fluid volume during the third trimester will increase the rate of cesarean section and the incidence of low weight infants , and the incidence will continuously increase with the decrease of amniotic fluid volume .
