Abstract

Aims: To compare the effects of the adoption of lateral positions and lithotomy positions during the passive and active phases of the second stage of labour on perineal outcomes. Design: An observational study with prospectively collected data, conducted in three hospitals in China. Method: Attending midwives recorded the perineal outcomes and characteristics of women giving birth between July–November 2020. Binary logistic regression was performed to explore the effects of lateral positions on perineal outcomes during different phases of the second stage of labour. The STROBE guidelines guided the reporting of this study. Results: Among primiparous women, when compared with those who adopted lateral positions during the passive phase of the second stage of labour and changed to lithotomy positions during the active phase, women who assumed lateral positions during both the passive and active phases had a higher rate of intact perineum/first-degree perineal tears and a reduced risk of episiotomy, and episiotomy/second-degree perineal tears. No significant difference was found in perineal outcomes between those who assumed lithotomy positions during the passive and active phases and those who adopted lateral positions during the passive phase and changed to lithotomy positions during the active phase. No significant difference was found in perineal outcomes among multiparous women, regardless of different positions adopted at the passive and/or the active phase. Conclusion: Lateral positions during the active phase may have protective effects on the perineum in primiparous women. However, adopting lateral positions only during the passive phase did not promote better perineal outcomes, regardless of parity. Relevance to clinical practice: This study will provide a further reference for the use of lateral positions during different phases of the second stage of labour among primiparous and multiparous women in clinical practice, contributing to the perineal protection during childbirth.
