The value of the biophysical profile scoring to predict occur-rate perinatal outcome in prolonged pregnancy, was assessed. 60 patients with the diagnosis of prolonged pregnancy were included in this prospective clinical trial. A fetal biophysical profile score, described by Manning and modified by Johnson, was recorded in all these patients. There were 40 cases (66%) with normal profile scoring 3 of which had a feature considered as perinatal morbidity (specificity 94.8%). In contrast, from 20 cases with abnormal profile scores, 18 (90%) had abnormal perinatal findings (sensitivity 85.7%). The false positive and negative rates were low, 10 and 7.5% respectively, and the global predictive value of this test was 90%. In our study the amniotic fluid volume was the profile variable most able to identify a compromised fetus and the second with the highest specificity. Although we had a high cesarean section rate, (71%), we suggest that with normal profile scores (greater than or equal to 8) and normal amniotic fluid volume, the fetal biophysical profile may be an accurate test in the evaluation of the fetal condition in this obstetric complication.
评估了生物物理评分对预测过期妊娠围产期结局发生率的价值。本前瞻性临床试验纳入了60例诊断为过期妊娠的患者。所有这些患者均记录了由Manning描述并经Johnson修改的胎儿生物物理评分。40例（66%）评分正常，其中3例有围产期发病特征（特异性94.8%）。相比之下，20例评分异常的病例中，18例（90%）围产期检查结果异常（敏感性85.7%）。假阳性率和假阴性率较低，分别为10%和7.5%，该检查的总体预测价值为90%。在我们的研究中，羊水量是最能识别受损胎儿的评分变量，也是特异性第二高的变量。尽管我们的剖宫产率较高（71%），但我们认为，评分正常（大于或等于8）且羊水量正常时，胎儿生物物理评分可能是评估这种产科并发症中胎儿状况的准确检查方法。
