[Frequency of obstetrical operations and perinatal mortality before and after admission of continuous fetal monitoring (author's transl)].
Two groups of obstetrical patients were statistically analyzed with a computer. The first group A (2339 deliveries, January 1967-June 1968) was controlled by conservative obstetrical methods, the second group B (2512 deliveries, January 1973-June 1974) was controlled by continuous monitoring of fetal heart rate and by analysis of fetal blood during labour. The results of the statistical analysis can be summarized: 1. The frequency of obstetrical operations (vacuum, obstetrical forceps, Caesarean section) increases from 12.8% (group A) to 22.5% (group B). 2. The percentage of Caesarean sections decided on for the sake of the child rose from 45.7% (group A) to 54.7% (group B). 3. Vital indications fell due to increasingly preventive obstetrics from 54.3% to 45.3%. 4. The frequency of Caesarean sections rose due to increasing indication "absolute or relative pelvic disproportion" of the mediterranean patients. 5. However the analysis of fetal blood during labour and the continuous monitoring of fetal heart rate has prevented a further increase of Caesarean sections. 6. The increasing percentage of obstetric forceps was due to our intention of preventing prolonged labour. 7. Maternal mortality after operative delivery reached 0.04% in group A and 0% in group B. 8. Perinatal mortality of children, delivered by operation, has decreased from 3.0% (group A) to 0,7% (group B). 9. The Apgar scores after operative deliveries were much better in group B (continuous fetal monitoring) than in group A (without fetal monitoring).
