用经腹壁超声检查联合经会阴超声检查对孕晚期孕妇进行前置胎盘筛查的效果分析

Effect of the abdominal wall and perineum ultrasonic detection for screening of placenta previa of later pregnancy

目的 :探讨采用经腹壁超声检查联合经会阴超声检查对孕晚期孕妇进行前置胎盘筛查的效果。方法 :将2016年9月至2017年4月期间遂宁市妇幼保健计划生育服务中心收治的104例孕晚期前置胎盘孕妇作为研究对象。先对这些孕妇进行经腹壁超声检查,再对其进行经会阴超声检查。然后,对比使用不同检查方式对孕晚期孕妇进行前置胎盘筛查的结果,并对比用不同检查方式诊断前置胎盘的敏感度和特异度。结果 :与使用经腹壁超声检查相比,使用经腹壁超声检查联合经会阴超声检查对孕妇进行前置胎盘筛查的结果为真阳性的比率较高,筛查结果为假阴性的比率较低(P<0.05)。与使用经腹壁超声检查相比,使用经腹壁超声检查联合经会阴超声检查诊断前置胎盘的敏感度较高、特异度较低(P<0.05)。结论:采用经腹壁超声检查联合经会阴超声检查对孕晚期孕妇进行前置胎盘筛查的效果较好。

objective： to explore the effect of peritoneal ultrasonography combined with perineal ultrasonography on preplacental screening of pregnant women in late pregnancy. Methods： 104 pregnant women with advanced placenta in late pregnancy admitted to suining maternal and child health and family planning service center from September 2016 to April 2017 were studied. The pregnant women were examined by transabdominal uhrasonography and then by perineal ultrasonography. Then, the results of placental preposition screening for pregnant women in late pregnancy using different examination methods were compared, and the sensitivity and specificity of placental preposition diagnosed by different examination methods were compared. Results： compared with the use of transabdominal wall ultrasound, the proportion of true positive and the proportion of negative in pre-placenta screening of pregnant women using transabdominal wall ultrasound combined with perineal ultrasound was higher （P 〈 0.05）. Compared with the use of transabdominal wall ultrasound, the sensitivity and specificity of the use of transabdominal wall ultrasound combined with transperineal ultrasound in the diagnosis of previa placenta were higher and lower （P 〈 0.05）. Conclusion： perineal uhrasonography combined with perineal ultrasonography is effective in screening placenta previa in pregnant women with late pregnancy,
