Influence of Laboring People's Mobility and Positional Changes on Birth Outcomes in Low-Dose Epidural Analgesia Labor: A Systematic Review with Meta-Analysis.

INTRODUCTION

Freedom of movement has been identified as a key issue for pregnant individuals during the birthing process, even if they opt for epidural analgesia, which has relegated people to more static positions during birth for many years. The aims of this systematic review were to evaluate the influence of mobility and positional changes on perinatal and neonatal outcomes in people in labor with epidural analgesia, describe the range of movement interventions used during the first and second stage of labor, and describe the level of motor blockade among people with low-dose epidural analgesia.

METHODS

Bibliographic databases (Web of Science, Cochrane, CINAHL) were consulted from December 2020 to January 2021. The articles selected were clinical trials and observational or analytical studies, the subject of which was mobilization during labor in people with epidural analgesia. The outcome measures were mode of birth, duration of labor, and extrauterine adaptation after birth. A narrative synthesis was used to describe the types of movements interventions employed during the stages of labor and the level of motor blockade among people with low-dose epidural analgesia.

RESULTS

Ten articles were selected (8 clinical trials, one cross-sectional study, and one quasiexperimental study), with a total sample of 6086 individuals. A meta-analysis showed nonsignificant results between groups for mode of birth (relative risk [RR], 1.00; 95% CI, 0.87-1.14), duration of labor (RR, 1.64; 95% CI, -34.57 to 37.86), and extrauterine adaptation after birth (RR, 0.86; 95% CI, 0.39-1.93). There was heterogeneity among studies in the type of movement interventions used during the first and second stage of labor.

DISCUSSION

Although no clear benefit was observed for mobilization in epidural labor, no detrimental effects were found either, so perinatal care providers should encourage mobilization if the laboring person so desires, throughout the entire childbirth process.
