目的:探讨产前超声测量多项指标预测胎儿体重的方法及其意义.方法:以在某院出生的1560例新生儿作为研究对象,在分娩前3天内超声测量胎儿体重、双顶径、腹围和股骨长,分析胎儿体重和各指标之间的关系.结果:1560例单胎足月胎儿,体重(3320.13±512.13)g,双顶径(92.75±4.29)mm,腹围(343.76±22.27)mm,股骨(71.20±3.37)mm.胎儿体重与双顶径、腹围和股骨之间均有相关性,相关系数r在0.672~0.767,且有统计学意义.多因素分析显示新生儿体重与腹围相关性最大,双顶径次之,股骨长最小.通过受试者工作曲线(ROC)分析,利用胎儿腹围、股骨长和双顶径来判定巨大儿的截断值分别为355.00mm、73.50mm和95.50mm, 灵敏度分别为68.8%、68.8%和62.5%, 特异度分别为77.9%、79.2%和76.6%.结论:分娩前超声测量胎儿腹围、股骨长、双顶径可预测新生儿出生体重,腹围大于355mm、股骨大于73.50mm、双顶径大于95.5mm对预测巨大儿有临床价值.

Objective:To discuss the method and significance of prenatal ultrasound measurement indexes in the prediction of fetal weight. Methods:1560 cases of neonates in a hospital were chosen as the research subject. Fetal weight, biparietal diameter, abdominal girth and femur length were measures ultrasonically 3 days before delivery, and fetal weight and various indexes were analyzed. Result:1560 singletons full-term fetus, weight (3320.13 ± 512.13)g,BPD(92.75±4.29)mm,abdominal girth(343.76±22.27)mm,femur length(71.20±3.37)mm. There is correlation between fetal weight and BPD, abdominal girth and femur length( r=0.672-0.767), and there is statistical significance. Multiple-factor analysis indicates that correlation between fetal weight and abdominal girth is the biggest, DBP and femur length follows. Through ROC analysis, cutoff values of fetal macrosomia on the basis of fetal abdominal girth, femur length and BPD is 355.00mm,73.50mm and 95.50mm respectively, sensitivity is 68.8,68.8%and 62.5%,specificity is 7.9%,79.2% and 76.6% respectively. Conclusion:Measurement of fetal abdominal girth, femur length and BPD before delivery can predict neonates' weight. It is of great clinical value to predict macrosomia if abdominal girth is larger than 355mm, femur is longer than 73.50mm,BPD is wider than 95.5mm.
