Music Therapy in Pain and Anxiety Management during Labor: A Systematic Review and Meta-Analysis.

The study of music therapy in labor is unknown. The main objective of this research was to evaluate the effectiveness of music therapy to manage pain and anxiety during labor. A search strategy was used with PubMed/MEDLINE, LILACS, Cochrane, TRIPDATABASE, and Google Scholar. The selection criteria were based on randomized clinical trials; quasi-experimental research on pain intensity and anxiety during labor was evaluated. The primary outcomes were measured by the Visual Analogue Scale (VAS). A meta-analysis of the fixed effects was performed using mean differences (MD). Twelve studies were included for the final analysis, six (778 women) of which were meta-analyzed. Decreased VAS scores for pain intensity associated with music therapy were found in the latent (MD: -0.73; 95% CI -0.99; -0.48) and active (MD: -0.68; 95% CI -0.92; -0.44) phases of labor. VAS scores for anxiety decreased both in the latent (MD: -0.74; 95% CI -1.00; -0.48) and active (MD: -0.76; 95% CI -0.88; -0.64) phases. Music therapy seems to have beneficial effects on pain intensity and anxiety during labor, especially for women giving birth for the first time. However, the evidence is qualified as low.
