[Advantages and disadvantages of deliveries after induction of labour by convenience (author's transl)].
The development of 601 deliveries after induction of labour by convenience, 92 births after induced labour following pregnancies at risk and 1829 births after spontaneous onset of labour were examined and compared. The data were recorded retrospectively and submitted to an electronic data processing. Patients with whom the labour was induced had the shortest birth times, the difference amounted on average to 2 hours. In the comparison collective with spontaneous setting in of labour a hypotonic uterus motility was found to be the most frequent pathological labour activity. Pathological pattern of heart frequency, especially late decelerations were most frequently registered with fetuses of the risk group. The frequency of the operative deliveries amounted to 13% in the case of the collective of the induced labour, 35,9% in the case of patients in the risk group, and 10% in the case of the comparison collective. Threatening fetal asphyxia and protracted extrusion period were in the case of primiparas after induced labour equally often the indication for a vaginal-operative delivery, whereas with the comparison collective, in the risk group and also with multiparas after induced labour, the threatening fetal asphyxia was primarily for the carrying out of a forceps delivery or a vacuum extraction. Concerning the birth weight and size the new-borns of the collectives examined showed no significant differences. The best Apgar-score was achieved by the new-born induced labour babies. Only 0,5% of these babies showed pronounced signs of placental dysfunction, in the risk group 9,6%, and in the comparison collective 1,6% of the babies were born with a pronounced Clifford-syndrome. Induced labour babies did not need any pediatric treatment. There were no perinatal deaths. In the case of comparison collective, long term pediatric treatment was necessary for 8 babies, 1 baby died subpartual, another one in the pediatric clinic, that means a perinatal mortality of 0,1%. In the risk group 3 babies needed pediatric treatment, 1 baby died of the consequences of a serious erythroblastosis, the perinatal mortality amounted to 1,1%. In a critical evaluation of the without exception favourable obstetrical results after induced labour, the technical, personal and organisational efforts should not be overlooked. This stands in the way of a widespread use of the process in the near future. The results hitherto permit the temporary inference that 1) psychologically positive prerequisites for the birth are created if the pregnant woman knows a firm date for the delivery, 2) the whole partus can be continuously supervised and the maternal and infantile emergencies prevented in good time and 3) through the calculability of risks during pregnancy and birth, perinatal mortality and morbidity can be reduced considerably.
