Influence of acupuncture on duration of labor.

The aim of this case control study was to evaluate the thus far controversially discussed influence of acupuncture (AP) on the duration of labor. Fifty-seven women with AP treatment (group A) were included in our study after spontaneous vaginal full-term delivery. The control group included 63 women (group B). Median duration of the first stage of labor was 196 min in group A and 321 min in group B (Wilcoxon 2-sample test, p < 0.0001). Median duration of the second stage of labor was 57 min in group A and 57 min in group B (Wilcoxon 2-sample test, p = 0.82). Thirty women had a premature rupture of the membranes (PROM), in group A 66.7% and in group B 33.3% (chi2 test, p = 0.02). Women without AP (group B) received significantly more often oxytocin during the first stage of labor compared with group A women (85 and 15%, respectively, chi2 test, p = 0.01) as well as during the second stage of labor (72 and 28%, respectively, chi2 test, p = 0.03). Our study suggests that AP treatment is a recommendable form of childbirth preparation due to its positive effect on the duration of labor, namely by shortening the first stage of labor.
