目的探讨孕期彩超提示羊水中密集光点与羊水粪染的相关性及对母儿预后等的影响。方法对衢州市妇幼保健院2012年1月—2013年2月分娩,且分娩前一周内彩超提示羊水中有密集光点的111名孕妇资料进行回顾性分析,选取同期无密集光点的117名孕妇作为对照,观察两组胎儿的生长测量指标、羊水指数、脐动脉S/D值、分娩方式、产程时间、羊水粪染率、新生儿体重、性别及新生儿窒息率。结果两组病例羊水粪染率、胎儿生长测量指标、脐动脉S/D值>3的比率及新生儿窒息率差异无统计学意义(P>0.05)。而密集光点组的剖宫产率、羊水指数、新生儿体重、男性新生儿数高于对照组,差异有统计学意义(P<0.05)。结论孕期彩超提示羊水中密集光点与胎儿体重、性别有关,其羊水粪染率、新生儿窒息率等不良结局未明显增加,应加强监护,争取阴道分娩,降低剖宫产率。
Objective To investigate the relationship between intensive ultrasound in amniotic fluid during pregnancy and meconium-stained amniotic fluid and its prognosis. Methods A retrospective analysis was conducted on 111 pregnant women who gave birth to intensive light spot in amniotic fluid within one week before delivery in Quzhou Maternal and Child Health Hospital from January 2012 to February 2013. 117 pregnant women with no intensive light spots in the same period were selected. Pregnant women as a control, observed fetal growth index, amniotic fluid index, umbilical artery S / D value, mode of delivery, labor duration, meconium-stained amniotic fluid, neonatal weight, gender and neonatal asphyxia. Results There was no significant difference in the rates of amniotic fluid, fetus growth, ratio of S / D> 3 and neonatal asphyxia between the two groups (P> 0.05). The cesarean section rate, amniotic fluid index, newborn weight and male neonates in intensive spot group were higher than those in control group, with significant difference (P <0.05). Conclusions Color Doppler ultrasound during pregnancy suggests that intensive light spots in amniotic fluid are related to fetal weight and sex, and its adverse outcomes such as meconium-stained amniotic fluid and neonatal asphyxia rate are not significantly increased. Careful vaginal delivery and vaginal delivery should be reduced and cesarean section rate should be reduced.
