经腹部及会阴部超声联合诊断前置胎盘的效果

Effect of Combined Transabdominal and Perineal Ultrasound in the Diagnosis of Placenta Previa

目的:探究对前置胎盘产孕妇施行经腹部及会阴部超声联合诊断的效果。方法:随机抽取2018年1月-2019年12月本院58例疑似前置胎盘孕妇为观察对象,对其均施行经腹部和会阴部超声检查,其中经腹部超声检查结果设为对照组,经腹部及会阴部超声联合诊断结果设为观察组。以产后结果为金标准,对比两组诊断效果。结果:经腹部超声检查结果显示43例为前置胎盘,误诊、漏诊分别为1、8例。腹部+会阴部超声检查显示48例为前置胎盘,漏诊2例,未出现误诊病例。一致性检测显示腹部超声检查、腹部+会阴部超声检查的Kappa值分别为0.812、0.921。腹部超声诊断前置胎盘的敏感度、特异度、准确率分别为84.00%、87.50%、84.48%,腹部+会阴部超声诊断前置胎盘的敏感度、特异度、准确率分别为96.00%、100%、96.55%,腹部+会阴部超声的敏感度、准确率较单纯腹部超声更高(P<0.05)。观察组前置胎盘分型诊断符合率(96.00%)高于对照组(84.00%),差异有统计学意义(P<0.05)。结论:对前置胎盘孕妇施行经腹部及会阴部超声联合诊断的效果更佳,诊断符合率更高,且安全性较好。

Objective:To explore the effect of combined transabdominal and perineal ultrasound in the diagnosis of placenta previa.Method:A total of 58 cases of pregnant women with suspected placenta previa in our hospital from January 2018 to December 2019 were randomly selected as the observation objects,and all of them underwent transabdominal and perineal ultrasound examination.The results of transabdominal ultrasound examination were set as the control group,and the combined diagnosis results of transabdominal and perineal ultrasound were set as the observation group.Postpartum results were used as the gold standard to compare the diagnostic effects of the two groups.Result:Transabdominal ultrasound examination showed that 43 cases were placenta previa,and misdiagnosis and missed diagnosis were 1 case and 8 cases.Ultrasonography of abdomen+perineum showed placenta previa of 48 cases,and missed diagnosis of 2 cases,no misdiagnosis was found.The consistency test showed that the Kappa values of abdominal ultrasound,abdominal+perineal ultrasound were 0.812 and 0.921,respectively.The sensitivity,specificity and accuracy of abdominal ultrasound in the diagnosis of placenta previa were 84.00%,87.50%,84.48%;the sensitivity,specificity and accuracy of abdominal and perineal ultrasound in the diagnosis of placenta previa were 96.00%,100%,96.55%,respectively;the sensitivity and accuracy of abdominal+perineal ultrasound were higher than those of abdominal ultrasound alone(P<0.05).Conclusion:The effect of transabdominal and perineal ultrasound combined diagnosis for placenta previa is better,the diagnostic coincidence rate is higher,and the safety is better.
