Moxibustion on Sanyinjiao shortens the active phase of the first stage of labour
To observe the effect of acupoint Sanyinjiao (SP6) moxibustion (S-Mox) on the duration of the first labor stage and uterine contractive pain in primiparae.
Sixty primipara women in labour were equally assigned according to their choice to three groups: women in the S-Mox group received bilateral S-Mox for 30 min, women in the non-acupoint group received moxibustion (Mox) applied on non-acupoints for 30 min, and those in the control group did not receive Mox intervention. The duration of the first labour stage was recorded and the degree of labour pain was estimated by a visual analogue scale (VAS) before and after Mox.
The duration of the first stage active phase in the S-Mox group was significantly shorter than that in the other two groups (P<0.05, P<0.01); the VAS score after Mox was lower in the S-Mox group, showing a statistical difference in comparison with the control group (P<0.05).
Applying S-Mox could markedly shorten the active phase of the first stage of labour and lower the VAS score of uterine contractive pain, which means alleviating the pain caused by vaginal delivery. Its mechanism is worthy of further study.
