An Evaluation of Acupressure on the Sanyinjiao (SP6) and Hugo (LI4) Points on the Pain Severity and Length of Labor: A Systematic Review and Meta-analysis Study.

Abstract

Background:In this study, the effects of SP6 and LI4 acupressure on the pain severity and length of labor are examined.Materials and Methods:This systematic review and meta-analysis study was performed on articles published in 2004–2015. The articles, published in the English and Farsi languages, related to the effects of acupressure on the SP6 and LI4 points on the length and pain severity of labor. Data were collected by searching medical databases, including PubMed, ISI, MagIran, Google Scholar, Iran Medex, SID, Irandoc, and EMBASE, for relevant material.Results:Women who received SP6 acupressure experienced less pain immediately after the intervention [−0.56, 95% confidence interval (CI): −0.77, −0.36] than women in the touch group and exhibited decrease in the length of labor (−0.99, 95% CI: −1.39, −0.39), the active phase (0.95, 95% CI: −1.30, −0.61), and the second stage of labor (−0.39, 95% CI: −0.74, −0.03). Women who received LI4 acupressure experienced less pain immediately after the intervention (−0.94, 95%, CI: −1.36, −0.53) than women in the touch group and exhibited shorter active phase (−0.91, 95%, CI: −1.18, −0.63) and second stage of labor (−0.55, 95%, CI: −0.95, −0.15) lengths.Conclusions:The use of SP6 and LI4 acupressure shows promise as a method for managing the length and pain severity of labor, but further study is required to establish its effectiveness along with other pharmacological and nonpharmacological methods.
