The effects of electrical fetal monitoring such as cardiotocogram (CTG) and nonstress test (NST) were studied during the years 1975-86 in 6,981 cases (6,893 singletons, 41 twins and 2 triplets). These cases were divided into three groups according to the mode of fetal monitoring. The first group was managed without electrical fetal monitoring (control group). The second was managed mainly with intrapartum fetal monitoring (transitional group) and the third was managed with antepartum and intrapartum fetal monitoring (fully monitored group). The incidence of cerebral palsy (CP) was investigated at the social health center during the same period. The introduction of intrapartum fetal monitoring resulted in a reduction in neonatal asphyxia from 7.0% in the control group to 5.2% and 4.3% in the transitional group and fully monitored group respectively. The perinatal mortality rate showed a significant reduction from 0.61% in the period without antepartum fetal monitoring to 0.31% in the fully monitored group, and this was attributed to the significant reduction in the number of stillbirths. The incidence of CP in the district decreased from 2.2 to 0.2 per 1,000 children during the period studied. In these circumstances, the caesarean section rate increased from 7.0% in the control group to 11.8% in the transitional group but decreased to 9.8% in the fully monitored group. These results showed the clinical and social benefits of electrical fetal monitoring.
1975年至1986年期间，对6981例病例（6893例单胎、41例双胎和2例三胎）进行了电子胎儿监护（如宫缩图（CTG）和无应激试验（NST））效果的研究。根据胎儿监护方式，这些病例被分为三组。第一组在没有电子胎儿监护的情况下进行管理（对照组）。第二组主要在分娩期进行胎儿监护（过渡组），第三组在产前和分娩期均进行胎儿监护（全程监护组）。同期在社会健康中心调查了脑瘫（CP）的发病率。分娩期胎儿监护的引入使新生儿窒息率从对照组的7.0%分别降至过渡组的5.2%和全程监护组的4.3%。围产儿死亡率从产前无胎儿监护时期的0.61%显著降至全程监护组的0.31%，这归因于死产数量的显著减少。在所研究的时期内，该地区脑瘫的发病率从每1000名儿童中的2.2例降至0.2例。在这种情况下，剖宫产率从对照组的7.0%升至过渡组的11.8%，但在全程监护组降至9.8%。这些结果显示了电子胎儿监护的临床和社会效益。
