A group of 27 premature fetuses, between 27 and 35 weeks of gestation, were studied in the fetal intensive care unit. Both late deceleration of fetal heart rate and loss of beta to beat variation were associated with significantly lower Apgar scores. Four of 5 of the very premature fetuses who died of asphyxia soon after birth, showed evidence of asphyxia in the fetal heart rate trace before birth. Because of the improved short- and long-term outlook for the liveborn very premature fetus, active obstetric intervention when intrauterine asphyxia is diagnosed may furthther improve survival rate.
在胎儿重症监护病房对一组27例孕27至35周的早产胎儿进行了研究。胎儿心率晚期减速和β波变异消失均与阿氏评分显著降低相关。5例出生后不久死于窒息的极早产胎儿中，有4例在出生前的胎儿心率描记图上显示有窒息迹象。由于存活的极早产胎儿的短期和长期预后有所改善，因此诊断出宫内窒息时进行积极的产科干预可能会进一步提高存活率。
