Satisfaction and dissatisfaction with pain relief and birth experience among induced and spontaneous-onset labours ending in vaginal birth: A prospective cohort study

Objective: To assess pain relief and overall birth experience in induced vs. spontaneous-onset labours and to clarify variables among induced parturients determining satisfaction and dissatisfaction. Study design: A prospective study of 2042 women. 575 women with induced and 1467 with spontaneous-onset labour answered multiple questions in a questionnaire regarding the experience of birth giving. Satisfaction was numerically assessed via a visual analogue scale (VAS 0–10). Results: Induction of labour (IOL) did not worsen the average experience of pain relief, but the proportion of women dissatisfied with pain relief was slightly higher after IOL compared with spontaneous-onset labour (SOL). IOL was associated with lower satisfaction with overall birth experience compared with SOL (VAS 8.0 vs. 8.4; p < 0.001). Among IOL parturients incorrect timing of pain relief was strongly associated with dissatisfaction with pain relief, as were deficient information and induction with misoprostol. Epidural blockade was the most important factor preventing dissatisfaction with pain relief. Unsatisfactory overall experience of birth was associated with deficient pain relief, its incorrect timing or deficient information, as well as vacuum extraction as the mode of delivery. Conclusions: Induction of labour is a risk factor of dissatisfaction regarding pain relief and overall birth experience. The strongest impact on dissatisfaction among induced parturients concerning pain relief was delayed timing of effective labour analgesia. Poor pain relief, its incorrect timing and deficient information on pain relief were strong predictive factors of dissatisfaction with the overall birth experience.
