The Relations and Clinical Verification between Biparietal Diameter ( BPD ) of Fetal Head and other Ultrasonic Measurements for Head Distances of Newborn

超声测量胎头双顶径与新生儿头径关系及与双顶径的临床验证

Or when biparietal diameter ( BPD )≥ 9.5 cm , and the length of femur ≥ 7.5 cm ;

胎儿双顶径大于等于9.5cm，股骨长径≥7.5cm时，巨大儿的发生率明显增加；

Results : The mean body weight , height , biparietal diameter and the ratio of male to female were significantly higher in the macrosomia group than in the control group .

结果：非糖尿病性巨大儿的平均胎龄、体重、身高、双顶径及男性比例均显著高于对照组；

Normally , if the head is at0 Station , the biparietal diameter is at the pelvic inlet and the head is fully engaged .

通常，如果胎头处于零点位置，双顶径与骨盆口契合，那么胎头可以充分进入。

Conclusion : 1 . The multiple regression equation established by the height of uterus , abdominal circumference , biparietal diameter and femur length was more accurate on the prediction of fetal weight . 3 .

结论1.采用宫高、腹围、双顶径、股骨长建立的多元回归方程对胎儿体重预测符合率较高，有较好的临床应用价值。

Results ( 1 ) Compared with the conventional group , the growth of fetal biparietal diameter , femur length , head circumference and abdomen circumference was better in the study group and the control group ( P0 . 01 ) .

结果（1）灯盏花素组与复方丹参组胎儿双顶径、股骨长、头围、腹围增大均优于常规治疗组和对照组（P0.01）。

Methods Measure the depth of the soft tissue in the back neck of fetus , Biparietal diameter ( BPD ) , femur length ( FL ) and abdominal circumference ( AC ), and apply linear regression equation .

方法超声测量胎儿颈后软组织厚度、双顶颈、股骨长径、腹围、应用线性回归方程求出各指标与胎儿体重的关系。

The ultrasonic determination of the biparietal diameter , abdomen diameter , femur length and the thigh diameter were made in 232 fetus . Statistical analysis of the data were performed by computer and three equations for estimating fetal weight were derived .

本文对232例胎儿的双顶径、腹径、股骨长度和股径进行了超声测定，将这些数据作统计分析后导出3个估计胎儿体重回归方程。

Not only the maternal fundal height and abdominal circumference , but also the fetal growth parameters , including biparietal diameter , head circumference , abdominal circumference , femur length in the CHM group increased much faster than those in the control group .

中药组母体宫高、腹围以及胎儿生长参数，包括双顶径、头围、腹围、股骨长的增长均较氨基酸组快。

Methods : The biparietal diameter , head circumference , abdominal circumference , femur length , bilateral kidney length , kidney width and kidney thickness of 319 singleton fetuses were measured by two-dimensional ultrasound . Bilateral kidney volume of all fetuses was calculated .

方法：以二维实时超声测量319例胎儿的双顶径、头围、腹围、股骨长径、双侧肾脏长径、横径及厚径，并计算每个胎肾体积。

Materials and methods Fetal biparietal diameter ( BPD ), abdominal circumference ( AC ), liver length ( LL ), femur length ( FL ) were measured by ultrasonography with the equation for a circle within 5 days of delivery and analyzed with neonatal birth weight in 262 cases .

材料与方法对262例在分娩前5天内，用B型超声测定胎儿双顶径、腹围、肝脏长度、股骨长度，分别用各种方程式得出胎儿体重，并与新生儿实际出生体重进行比较。
