Antepartum foetal monitoring is crucial for the detection of foetuses at risk so that timely intervention can improve the perinatal outcome. The evidence underlying the most common modalities of antepartum foetal monitoring used are appraised and presented in this article. Foetal movement chart should be used in high-risk pregnancies but not recommended routinely in low-risk pregnancies. Symphysis-fundal height measurement, being associated with low cost and ease of use, is a reasonable screening tool for foetal well-being. Third trimester ultrasonography is, thus far, the best modality available for the assessment of foetal growth, and can be used until a better modality for foetal growth assessment becomes available. Antepartum cardiotocography can be used to monitor foetal well-being in normal pregnancies beyond the estimated date of delivery but it probably serves little purpose prior to that. Well-designed controlled studies evaluating modalities for antepartum foetal monitoring are generally lacking. With the advance of medical science, more research should be focused on this aspect of obstetric care so that our practice can become more evidence-based.
产前胎儿监测对于发现有风险的胎儿至关重要，以便及时干预能够改善围产期结局。本文对常用的产前胎儿监测最常见方式的相关证据进行了评估和阐述。胎动计数图表应用于高危妊娠，但不建议在低危妊娠中常规使用。耻骨联合上缘至宫底高度测量，因其成本低且易于操作，是评估胎儿健康状况的一种合理筛查工具。到目前为止，孕晚期超声检查是评估胎儿生长的最佳方式，并且在更好的胎儿生长评估方式出现之前都可使用。产前胎心监护可用于超过预产期的正常妊娠中监测胎儿健康状况，但在此之前可能作用不大。普遍缺乏设计良好的对照研究来评估产前胎儿监测方式。随着医学科学的进步，应更多地关注产科护理的这一方面，以便我们的实践能更有循证依据。
