Two hundred one patients with high-risk pregnancy and 66 patients with term uncomplicated pregnancy underwent a nonstress test 7 days or less prior to delivery. The incidence of spontaneous fetal heart rate decelerations in the high-risk group was 5.5%. None of the fetuses in the normal group showed this finding. Among those infants presenting with spontaneous decelerations, there was an 18.2% mortality. Disturbances of intrauterine growth were found in 63.6% of cases. The possible metabolic mechanisms and clinical implications underlying this finding are discussed.
201例高危妊娠患者和66例足月正常妊娠患者在分娩前7天或更短时间内进行了无应激试验。高危组胎儿心率自发减速的发生率为5.5%。正常组胎儿均未出现这一情况。在出现自发减速的婴儿中，死亡率为18.2%。63.6%的病例发现有宫内生长障碍。本文讨论了这一发现潜在的代谢机制和临床意义。
