[Studies on the effectiveness of obstetric epidural analgesia. I. Vaginal delivery (author's transl)].

In a retrospective study 1,000 women who in 1979 had undergone a delivery either under epidural-anaesthesia or without, and instead either relation training or pethidine in small doses (20-30 mg i.v.) at the Ulm Department of Obstetrics, were followed up by questionnaire. The women of the epidural group felt that they had been adequately informed about the various possibilities of pain relief during labour, while some of the control group felt that they had been inadequately or even incorrectly informed. In the epidural group, pain relief during labour was such that 90% had hardly experienced any, or only mild discomfort, similar degree of pain relief was described by a many as 68.7% of the control group. Especially in the case of primigravida, the women of the epidural group had an insufficient urge to bear down, hence the rate of forceps delivery was relatively high, whereas this problem did not arise in the control group, where the forceps rate was markedly lower. The incidence of headache and back pain was only slightly higher in the epidural as compared to the control group, where other complaints were more frequent. 82% of the epidural group said that they would again choose this form of analgesia for future deliveries, 15% would not. In the control group 22% said that they would like an epidural for future deliveries, while 21% would not. The Apgar scoring and pH values of the newborn showed no significant differences between the groups.
