Nonpharmacological labor pain management methods and risk of cesarean birth: A retrospective cohort study

The trends and hotspots of research on non-pharmacological interventions for labor pain management: a bibliometric analysis

INTRODUCTION

This study aimed to examine important points of focus, trends, and depth of research on non-pharmacological interventions for the management of labor pain worldwide from a macro perspective and present an extensive definition of research fields regarding non-pharmacological interventions.

METHODS

Bibliometric methods were used in this study. With comprehensive keyword lists, the Web of Science and PubMed databases were searched using different screening strategies for publications made until 25 February 2023.

RESULTS

Studies on non-pharmacological interventions in the management of labor pain have continued to develop since 2003 with great momentum. In this study, the most productive country in research on non-pharmacological interventions was found to be Iran, while Australia, the USA, China, and the United Kingdom were the most notable ones in terms of collaboration. The most prevalently studied non-pharmacological interventions were hydrotherapy and acupuncture. The results of the co-word analysis revealed 5 main themes about this field of research.

CONCLUSION

The results of this study showed that interest in studies on non-pharmacological interventions in the management of labor pain has increased, the quality of research in the field is high, international collaboration is increasingly higher, and technological approaches have started to emerge in relevant studies.

The effectiveness of auricular acupressure on pain management during labor: A systematic review and meta-analysis of randomized controlled trials

AIM

This meta-analysis aimed to systematically evaluate the effectiveness of auricular acupressure on pain management during labor.

METHODS

Six English and three Chinese electronic databases were comprehensively searched from inception to 6 November 2021. The PRISMA checklist was followed. The methodological quality of the included studies was assessed with the Cochrane Collaboration Bias Risk Assessment Tool. The meta-analysis was performed using Review Manager 5.3 software. Heterogeneity between studies was calculated using I² .

RESULTS

Five studies comprising 312 participants were included. The labor pain scores of the auricular acupressure group were significantly lower than those of the usual care group at cervix dilations of 6, 8, and 10 cm, with mean differences (95% confidence intervals) of -1.05 (-1.41, -0.69), -1.44 (-2.07, -0.82), and -1.96 (-3.30, -0.61), respectively. Auricular acupressure can thus effectively improve the labor pain perception at cervix dilations of 6, 8, and 10 cm. Moreover, auricular acupressure shortened the active phase, and had the trend of shortening the second and third stages of labor. There was no evidence that auricular acupressure had an effect on the rate of cesarean section or the 1 and 5 min Apgar scores.

CONCLUSION

Effective labor pain relief, better labor pain perception, and the lack of adverse effects support the use of auricular acupressure. More high-quality and rigorous trials are needed to verify our findings before we can make strong recommendations.
