A prospective survey of 1091 Finnish parturients was conducted in order to ascertain mothers' expectations for labour pain relief, to measure the actual pain during all three stages of labour and to question their satisfaction and the adequacy of pain relief on the third day following delivery. Antenatal expectations for pain relief were surveyed. Mothers were questioned on pain levels in the delivery room and 3 days after giving birth. Pain levels were ascertained using a visual pain score method. Antenatally, 90% of all parturients anticipated a need for pain relief during labour. In the delivery room over 80% of all parturients described their pain as very severe to intolerable, only 4% of the multiparous had low pain scores (0-2). After pain treatment 50% of multiparous women still had pain scores from 8 to 10, which reflects a lack of effective pain relief. Dissatisfaction with the childbirth experience was very low, and was associated with instrumental deliveries, but not with the usage of analgesia. 51% of all parturients complained of inadequate pain relief during childbirth, which, in multiparous women, was significantly associated with the second stage of labour.

Labour pain was measured with the McGill Pain Questionnaire in 87 primiparas and 54 multiparas. The average intensity of labour pain ranked among the most intense pains recorded with the questionnaire. However, the pain scores had a wide range and were influenced by several medical and social variables. They were significantly higher for the primiparas than for the multiparas. Moreover, high pain levels were associated with a history of menstrual difficulties and lower socioeconomic status. The primiparas who had received prepared childbirth training had lower pain scores than those who had received no such training. Nevertheless, the effects of prepared childbirth training were relatively small, and most patients (81%) who received it requested epidural anesthesia. Because many women who received training suffered severe pain during labour, prepared childbirth training and epidural anesthesia should be regarded as compatible, complementary procedures.
