To test the predictive accuracy of five fundal height growth curves in the identification of twin gestations and small-, appropriate-, and large-for-gestational age neonates.
Retrospective review of prenatal records.
Perinatal clinic at a tertiary-care center.
Five hundred seven medically indigent women.
Fundal height measurements were tested against the limits of normal for each week of gestation on five fundal height curves. Neonates were classified as small-, appropriate-, or large-for-gestational age (based on weight for gestational age), except for twin gestations, which were classified as twins.
The accuracy of the predictions depended on which curve was used and what criteria were used to classify fundal height measurements as abnormal. Small-for-gestational age neonates (n = 40) were correctly predicted in 27.5-70% of the cases, large-for-gestational age neonates (n = 74) in 36.5-98.6% of the cases, and all four twin gestations.
Clinicians should test the accuracy of any fundal height curve before using it in practice.
测试五条宫高增长曲线在识别双胎妊娠以及小于胎龄儿、适于胎龄儿和大于胎龄儿方面的预测准确性。
对产前记录进行回顾性分析。
一家三级医疗中心的围产期诊所。
507名贫困孕妇。
根据五条宫高曲线上妊娠各周的正常范围来检测宫高测量值。除双胎妊娠归为双胎外，新生儿按小于胎龄儿、适于胎龄儿或大于胎龄儿分类（基于胎龄体重）。
预测的准确性取决于使用哪条曲线以及将宫高测量值分类为异常所采用的标准。小于胎龄儿（n = 40）在27.5% - 70%的病例中被正确预测，大于胎龄儿（n = 74）在36.5% - 98.6%的病例中被正确预测，所有四例双胎妊娠均被正确识别。
临床医生在实际应用任何宫高曲线之前应测试其准确性。
