Semiquantitative and quantitative principles of cardiotocogram evaluation are necessary for the evaluation of subacute and chronic oxygen deficiency in fetuses. By means of tcPO2 measurement it is possible to check these evaluation principles for their relation with fetal oxygen pressure. From 59 tcPO2 cardiotocograms, a total of 99 30-minute-intervals were analysed. 27% of the fetuses showed growth retardation (below the tenth weight percentile according to Kyank). Fetal oxygen pressure was statistically significantly (alpha less than 0.05) correlated with changes in the CTG score according to Hammacher. In the group with hypoxemic oxygen pressure (below 11 mmHg/1.47 kPa) the correlation was particularly high, and the CTG score of 5 points was significantly poorer than the 3 points in the nonhypoxemic control group. Our investigations essentially confirm the grading of the CTG score by Hammacher. Hypotrophic fetuses showed a significantly poorer CTG score, and their oxygen pressure of 12.9 mmHg (1.7 kPa) was significantly below that of the control group (15.4 mmHg/2.1 kPa).
胎儿心动图评估的半定量和定量原则对于评估胎儿亚急性和慢性缺氧是必要的。通过测量tcPO2，可以检查这些评估原则与胎儿氧压的关系。从59份tcPO2心动图中，共分析了99个30分钟的时间段。27%的胎儿显示出生长迟缓（根据Kyank标准低于第十体重百分位数）。胎儿氧压与根据Hammacher标准的CTG评分变化在统计学上有显著相关性（α小于0.05）。在低氧压组（低于11 mmHg/1.47 kPa）中，相关性尤其高，5分的CTG评分明显低于非低氧对照组的3分。我们的研究基本上证实了Hammacher对CTG评分的分级。发育迟缓的胎儿显示出明显较差的CTG评分，其12.9 mmHg（1.7 kPa）的氧压明显低于对照组（15.4 mmHg/2.1 kPa）。
