Abstract

The relationship of three different fetal ponderal indexes was studied in 116 normal pregnancies between 20 and 41 weeks. All three fetal ponderal indexes were found to be independent of gestational age. Throughout normal gestation, the femur length to abdominal circumference ratio X 100 was found to be 22.3 +/- 2.4 (mean +/- 2 SD), the tibia length to abdominal circumference ratio X 100 19.3 +/- 2.2 (mean +/- 2 SD), and the femur plus tibia length to abdominal circumference ratio X 100 41.6 +/- 4.2 (mean +/- 2 SD). The clinical applications of the different fetal ponderal indexes in evaluating fetal growth are discussed. Because they are independent of gestational age, the fetal ponderal indexes should prove most useful in evaluating fetal growth in high-risk patients with unknown dates.

摘要

对116例孕20至41周的正常妊娠孕妇进行了三种不同胎儿体重指数关系的研究。发现所有三种胎儿体重指数均与孕周无关。在整个正常妊娠期，股骨长度与腹围之比×100为22.3±2.4（均值±2标准差），胫骨长度与腹围之比×100为19.3±2.2（均值±2标准差），股骨加胫骨长度与腹围之比×100为41.6±4.2（均值±2标准差）。讨论了不同胎儿体重指数在评估胎儿生长中的临床应用。由于它们与孕周无关，胎儿体重指数在评估预产期不明的高危患者的胎儿生长方面应最为有用。
