目的构建正常胎儿五指测量的年龄特异性参考区间。患者和方法对在大学附属综合医院产前超声科评估的胎儿进行前瞻性横断面研究。研究队列由 1997 年 12 月至 2000 年 6 月期间到我们诊所进行常规胎儿生物测定或异常扫描的 302 名孕妇组成。她们都符合研究纳入标准：单胎胎儿具有正常的解剖结构、准确的胎龄和无妊娠并发症。每个胎儿只扫描一次，并获得一只手的手指测量值。将电子卡尺放置在近节指骨的外缘至远端指骨水平的外缘。这些测量值和相关孕龄均记录在计算机数据库中。 结果 在评估的妊娠范围内绘制了五个手指中每一个手指尺寸的线性增加（P
Objective To construct age-specific reference intervals for measurement of five digits in normal fetuses.Patients and Methods Prospective cross-sectional study of fetuses assessed at an antenatal ultrasound unit in a university-affiliated general hospital. The study cohort comprised 302 pregnant women attending our clinic for routine fetal biometry or anomaly scan between December 1997 and June 2000. They all fulfilled the study inclusion criteria: singleton fetuses with normal anatomy, accurate gestational age and no medical complications of pregnancy. Each fetus was scanned once only and the finger measurements of one hand were obtained. Electronic calipers were placed on the outer margin of the proximal phalanx to the outer margin of the distal phalanx level. Those measurements and the relevant gestational age were registered in a computerized database.Results The linear increase of size of each of the five fingers was plotted across the evaluated range of gestation (P
