The influence of gestational age on the probable meaning of features in the antepartal CTG which are not clearly pathological was investigated in 232 births in 1973/74. The umbilical artery pH was significantly lower among premature infants exhibiting abnormal, than among those exhibiting normal CTG patterns. No similar difference was found in term or overdue births. The clinical diagnosis of neonatal condition using the Apgar scheme confirmed biochemical findings: The frequency of depressed babies is in turn clearly higher in cases with abnormal antepartal CTG patterns. It is assumed that the reason for this is the higher sensitivity of premature babies to haemodynamic disturbances. Thus, it follows that premature babies exhibiting antepartal patterns which are not completely normal require close observation.
1973/74年对232例分娩进行了研究，以探讨胎龄对产前CTG中并非明显病理性特征的可能意义的影响。脐动脉pH值在产前CTG模式异常的早产儿中显著低于模式正常的早产儿。足月或过期产儿中未发现类似差异。使用阿普加评分法对新生儿状况进行的临床诊断证实了生化检查结果：产前CTG模式异常的病例中，新生儿窒息的发生率明显更高。据推测，原因是早产儿对血流动力学紊乱更为敏感。因此，产前模式不完全正常的早产儿需要密切观察。
