This study describes the accuracy of Leopold maneuvers as a screening procedure for fetal malpresentation. The frequency of fetal malpresentation ranges from 15 percent at 32 weeks to 4 percent at term. We prospectively determined fetal presentation by performing Leopold maneuvers on 150 women, followed by a fetal ultrasound examination for comparison. Experienced certified nurse-midwives performed the maneuvers with high sensitivity (88%), specificity (94%), positive predictive value (74%), and negative predictive value (97%) in a population with a 17 percent frequency of fetal malpresentation. We conclude that the maneuvers used by experienced clinicians can be effective as a screening tool for fetal malpresentation, particularly in settings where ultrasound may not be readily available.
本研究描述了利奥波德手法作为胎儿胎位异常筛查程序的准确性。胎儿胎位异常的发生率在孕32周时为15%，足月时为4%。我们前瞻性地对150名女性进行了利奥波德手法检查以确定胎儿胎位，随后进行胎儿超声检查以作比较。经验丰富的注册护士助产士在胎儿胎位异常发生率为17%的人群中进行该手法检查，其敏感性为88%，特异性为94%，阳性预测值为74%，阴性预测值为97%。我们得出结论，经验丰富的临床医生所使用的该手法可作为胎儿胎位异常的有效筛查工具，尤其是在无法轻易获得超声检查的情况下。
