Fetal heart rate tracings were obtained in 50 patients who had a normal 1st stage of labour until delivery of the baby. Fetal condition at birth was assessed by umbilical cord artery (UCA) pH and Apgar scores. Forty-eight of the 50 fetal heart tracings showed frequent, marked, early decelerations throughout the 2nd stage of labour. These tracings, when not accompanied by other pathological features, were associated with a good fetal outcome at birth.
对50例第一产程正常直至胎儿娩出的患者进行了胎心监护。通过脐动脉(UCA)pH值和阿氏评分评估出生时的胎儿状况。50例胎心监护中有48例在第二产程中出现频繁、显著的早期减速。这些监护结果在不伴有其他病理特征时,与出生时良好的胎儿结局相关。
