产前骨盆三维导航在阴道分娩中的应用价值

Application value of prenatal pelvic three-dimensional navigation in vaginal delivery

目的观察产前骨盆三维导航在阴道分娩中的应用价值。方法选取407例行产前骨盆三维导航检查产妇,统计产妇基本情况,并分析骨盆三维导航检查结果与分娩结局,观察其应用价值。结果孕妇耻骨弓角度在65.41°-139.76°,平均(108.74±8.76)°,其中耻骨弓角度异常值65.41°。孕妇耻骨弓角度检查范围在100-119为286例,占比为70.27%,相对于其他范围而言,差异具有统计学意义(P<0.05)。361例(占比88.70%)结果正常,46例结果异常中(占比11.30%)存在17例早产,29例出生低体重儿。其中胎儿体积<9.0 mm^(3)正常221例(占比同类型90.57%),早产/出生体重低23例(占比同类型9.43%);胎儿体积在≥9.0 mm^(3)正常140例(占比同类型85.89%),早产/出生体重低23例(占比同类型14.11%),差异具有统计学意义(P<0.05)。结论实施产前骨盆三维导航,对妊娠满36周后的胎儿头围和孕妇耻骨弓角度进行超声评估,可预测分娩期存在的风险,尽早计划分娩结束妊娠,保障母婴健康,具有临床应用价值。

Objective To observe the application value of prenatal pelvic 3D navigation in vaginal delivery.Methods 407 parturient women who underwent prenatal three-dimensional navigation examination of the pelvis were selected to collect the basic information of the parturient,analyze the results of three-dimensional navigation examination of the pelvis and the outcome of childbirth,and observe its application value.Results The Angle of pubic arch in pregnant women ranged from 65.41°to 139.76°,with an average of(108.74±8.76)°,and the abnormal value of pubic arch Angle was 65.41°.There were 286 cases in the pubic arch Angle examination range from 100 to 119 in pregnant women,accounting for 70.27%.Compared with other ranges,the difference was statistically significant(P<0.05).The results of 361 cases(88.70%)were normal.Among the 46 cases(11.30%)with abnormal results,17 cases were premature and 29 cases were bom with low birth weight.There were 221 cases with normal fetal volume<9.0 mm^(3)(90.57% of the same type)and 23 cases with premature birth/low birth weight(9.43% of the same type).There were 140 cases with normal fetal volume ≥9.0 mm^(3)(85.89% of the same type),and 23 cases with premature birth/low birth weight(14.11%of the same type),the difference was statistically significant(P<0.05).Conclusion Prenatal three-dimensional pelvic navigation,ultrasonic evaluation of fetal head circumference and pubic arch Angle of pregnant women after 36 weeks of gestation,can predict the risks during childbirth,plan to end pregnancy as early as possible,and protect maternal and infant health,which has clinical application value.
