Antenatal fetal monitoring is the principal means of distinguishing the fetus requiring imminent delivery from that which is coping well in utero. The ability to detect fetal compromise, defined by fetal acidosis, in a low-risk population was evaluated in a prospective study of 50 women undergoing a Caesarean section in the absence of labour. The sensitivity and positive predictive value of a modified biophysical profile (BPP) or Doppler velocimetry to detect a fetus subsequently born with an umbilical artery pH of less than 7.20 was poor. The incidence of fetal acidosis in the population under study was 8%. Interpretation of antenatal fetal assessments must be tempered by the clinical features of each case. Decisions to deliver should take into account the low sensitivity of these tests in the absence of other complicating factors.
产前胎儿监测是区分需要紧急分娩的胎儿与在子宫内情况良好的胎儿的主要手段。在一项对50名未临产而行剖宫产的妇女进行的前瞻性研究中，评估了在低风险人群中检测由胎儿酸中毒定义的胎儿窘迫的能力。改良生物物理评分（BPP）或多普勒血流速度测定法检测随后出生时脐动脉pH值小于7.20的胎儿的敏感性和阳性预测值较差。研究人群中胎儿酸中毒的发生率为8%。对产前胎儿评估的解读必须结合每个病例的临床特征。在没有其他复杂因素的情况下，分娩决策应考虑到这些检查的低敏感性。
