Abstract
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(P<0. 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.关键词
