Abstract

Fetal heart rate (FHR) patterns were analysed during last hour of labour and correlated to umbilical artery pH and catecholamine (CA) levels. Fetuses with pathological FHR had significantly higher levels of CA than those with normal FHR. Particulary high levels were found in fetuses with bradycardia and late decelerations. FHR was further analysed by a computer (DPAC, data processor and computer) in 100 women during last hour of labor. No correlation between deceleration areas of variability and umbilical artery pH and CA was found. It is concluded that although there is a good correlation between the general FHR-pattern and umbilical artery CA and pH it is impossible to quantify the degree of fetal distress by calculation of deceleration areas and variability.

摘要

在分娩的最后一小时对胎儿心率（FHR）模式进行了分析，并将其与脐动脉pH值和儿茶酚胺（CA）水平相关联。具有病理性FHR的胎儿的CA水平显著高于具有正常FHR的胎儿。在心动过缓和晚期减速的胎儿中发现了特别高的水平。在100名妇女分娩的最后一小时，通过计算机（DPAC，数据处理器和计算机）对FHR进行了进一步分析。未发现减速变异性区域与脐动脉pH值和CA之间存在相关性。得出的结论是，尽管一般FHR模式与脐动脉CA和pH值之间存在良好的相关性，但通过计算减速区域和变异性来量化胎儿窘迫的程度是不可能的。
