PURPOSE
This study was to evaluate the accuracy and clinical application of a new technique in the fetal weight estimation by ultrasound.
METHODS
The fetal biparietal diameter (BPD), head circumference (HC) and femur length (FL) were measured by ultrasound examination within one week before delivery. Two different fetal abdominal sectors were measured for the assessment of abdominal circumference (AC). The fetal weight of 516 singleton fetuses was estimated according to above measurements and their actual birth weight was recorded after delivery.
RESULTS
There were no significant differences in the fetal AC or body weight evaluated before delivery and recorded after delivery.
CONCLUSION
This new technique is more convenient and applicable for the evaluation of fetal AC as compared to standard method, and seems to be reliable and accurate for the assessment of fetal weight.
目的
本研究旨在评估一种超声估测胎儿体重新技术的准确性及临床应用价值。
方法
在分娩前一周内通过超声检查测量胎儿双顶径（BPD）、头围（HC）及股骨长度（FL）。测量两个不同的胎儿腹部区域以评估腹围（AC）。根据上述测量值估算516例单胎胎儿的体重，并在分娩后记录其实际出生体重。
结果
分娩前评估的胎儿AC及体重与分娩后记录的结果无显著差异。
结论
与标准方法相比，这种新技术在评估胎儿AC时更方便且适用，在评估胎儿体重方面似乎可靠且准确。
