Maternal childbirth experience and pain relief methods: a retrospective 7-year cohort study of 85 488 parturients in Finland

• The aim of this study was to analyse the relation between the used labour pain relief and childbirth experience measured by Visual Analogue Scale (VAS).DesignA retrospective cohort study.SettingChildbirth in five Helsinki University Hospital delivery units from 2012 to 2018.Primary outcome measureChildbirth experience measured by VAS and classified in three groups (negative VAS=1–5, positive VAS=6–8 and highly positive=9–10).ResultsThe use of epidural or non-epidural compared with non-medical pain relief methods decreased the likelihood to experience highly positive childbirth for primiparous (adjusted OR (aOR)EPIDURAL=0.64, 95% CI 0.57 to 0.73; and aORNON-EPIDURAL=0.76, 95% CI 0.66 to 0.87) and multiparous (aOREPIDURAL=0.90, 95% CI 0.84 to 0.97 and aORNON-EPIDURAL=0.80, 95% CI 0.74 to 0.86) parturients. The effects of epidural differed between primiparas and multiparas. In multiparas epidural was associated with decreased odds for experiencing negative childbirth compared with the non-medical group (aOR=0.70, 95% CI 0.57 to 0.87), while the effect of epidural was considered insignificant in primiparas (aOR=1.28, 95% CI 0.93 to 1.77).ConclusionWhile the use of medical—epidural and non-epidural—pain relief methods were not associated with odds for experiencing negative childbirth in primiparas, using epidural helps to avoid negative experience in multiparas. However, the odds for experiencing highly positive childbirth were decreased if the parturients used any medical pain relief for both primiparas and multiparas. Consequently, the effect of pain relief on the childbirth experience is strongly confounded by indication. Thus, the use of pain relief per se plays a limited role in the complex formation of the overall childbirth experience.
