摘要
目的探讨胎头方位及母体体位对胎儿外耳超声显示率的影响。方法用经第一颈椎双耳平面(FCEP)法联合改变母体体位对1 942只胎儿外耳进行超声检查。将胎头方位分为14种,记录改变母体体位前、后各胎头方位下胎儿外耳的超声显示率。结果改变母体体位前胎儿外耳总显示率为56.75%,其中正枕前为100%;正枕后为72.29%,其余胎头方位显示率较低。改变母体体位后胎儿外耳总显示率为87.85%,与改变母体体位前比较差异有统计学意义(P<0.01)。胎儿外耳显示率高的胎头方位是枕朝左前、枕朝左、枕朝右。结论不同胎头方位下的胎儿外耳超声显示率不同,改变母体体位是提高胎儿外耳显示率的有效方法。
Objective To explore the influence of fetal head orientation and maternal postures on ultrasound display rate of fetal external ear.Methods Ultrasound examination was employed to scan 1 942 fetal external ears using first cervical and ear-plane（FCEP） method combined with changing maternal postures.The fetal head orientation was divided into 14 types.Ultrasound display rates of fetal external ears under different fetal head orientation before and after changing maternal postures were recorded.Results The total ultrasound display rates of fetal external ears before changing maternal postures was 56.75%,among which direct occiput anterior position was 100%,direct occiput posterior was 72.29%,and the rest of the fetal head orientation showed lower display rate.The total ultrasound display rates of fetal external ears after changing maternal postures was 87.85%,which demonstrated significant difference compared with that before changing maternal postures（P0.01）.Fetal head orientation with high display rates of fetal external ear included left occiput anterior,left occiput transverse and right occiput transverse.Conclusion Ultrasound display rates of fetal external ear under different fetal head orientation is diverse,which can be improved by changing maternal postures.
