Objective To observe the effect of moxibustion on Sanyinjiao, Hegu acupoint first active phase of labor contractions pain.Methods One hundred and sixty cases of primipara were divided into test group by single blind, randomized methods (the Sanyinjiao acupoint group, Sanyinjiao acupoint and hegu point group) and control group(non-acupuncturev points group and the blank group).Each group with 40 cases.The patients were exerted mxibustion therapy 30 min in the Sanyinjiao acupoint group and Sanyinjiao acupoint and hegu point group, respectively in the maternal appear regularity uterine contraction pain, after ostium of uterus opened 3 cm.The women of the non-acupuncturev points group were exerted moxibustion therapy in the wrist horizontal stripes of radial side radial pulse place to elbow horizontal stripes biceps tendon of the midpoint of the radial side of attachment 30 min.The blank group women didn' t conduct notcarry moxibustion intervention.On the first active stage of labor time and uterine contraction pain were compared.Results The active labor time of Sanyinjiao group, Sanyinjiao and Hegu group,non acupoint group and blank control group patients were (116.11 ±65.89) min, (81.93 ± 53.45) min, (123.03 ± 7.67) min, (138.69 ± 104.01) min respectively, there was significant difference among Sanyinjiao and Hegu group, non acupoint group and blank group (P＜ 0.05), while the difference between the non acupoint group and blank group without statistical significance (P＞0.05).The first time of production process of 4 groups were (313.22± 141.15) min, (379.50± 182.82) min, (393.00 ±196.50) min, (488.08±236.61) min respectively, there was significant difference among Sanyinjiao group,Sanyinjiao and Hegu group and blank group differences (P ＜ 0.05).Moxibustion therapy after stopping, 2 h degree of cervical dilation of 4 groups were (8.37±2.19) cm, (8.14±2.74) cm, (7.64±2.91) cm, (6.29 ±3.05) cm respectively;contractions lasting time were (0.56±0.16) min, (0.52±0.13) min, (0.:48±0.17) min, (0.41± 0.09) min respectively;uterine contraction interval (2.98± 1.45) min, (2.56± 1.02) min, (3.89 ±1.54) min, (3.41 ± 1.32) min respectively;contraction strength enhaucement efficiency were 60.0％ (24/40) ,75.0％ (30/40), 17.5％ (7/40), 10.0％ (4/40) respectively, there were significant differences among Sanyinjiao group,Sanyinjiao and Hegu group,the non acupoint group and blank control group in terms of above indexes (P ＜ 0.05), while difference between the non acupoint group and blank group without statistical significance(P＞0.05).After the withdrawal of the moxibustion treatment 2 h, the pain reduction in childbirth of 4 groups were 52.5 ％ (21/40), 47.5％ (19/40), 22.5％ (9/40), 20％ (8/40) respectively, the pain reduction in childbirth of Sanyinjiao group, Sanyinjiao and Hegu Point Group were higher than that of non acupoint group and blank group, the differences were statistically significant (P＜0.05);while non acupoint group and blank group compared without statistically significant (P＞0.05).Conclusion The effect of Moxibustion at Sanyinjiao and Sanyinjiao compatibility Hegu Acupoint moxibustion on maternal production process and uterine contraction are significant, but combine with Acupoint Moxibustion can shorten the time of the active phase of labor, increase contraction of the uterus, promote the production process.
