To observe the impacts of electroacupuncture (EA) at Sanyinjiao (SP 6) on labor and assess its safety.
The random and single-blind method was adopted to divide 111 cases of the puerperas of natural delivery into an EA group (38 cases), a sham-acupuncture group (37 cases) and a blank control group (36 cases). In EA group, Sanyinjiao (SP 6) was selected and stimulated with Han's acupoint nerve stimulator (HANS). In the sham-acupuncture group, the puerperas were stimulated only with the needle tube, needle removed in advance and they felt subjectively to be needled. Afterward, the filiform needle was attached to Sanyinjiao (SP 6) with the needle tip wrapped with the adhesive plaster in advance, then HANS which one conducting wire was cut off in was connected. In the blank control group, no any treatment was applied, but the same indices were recorded at corresponding time points. The blood pressure and the heart rate of the puerperas as well as the heart rate of fetus were measured in 20 min of EA and 30 min after needle removal in three groups separately. The bleeding 24 h after labor and 1 min Apger score of the newborns were observed.
In EA group, the active phase of the 1st labor stage ((4.38 +/- 1.76)h) was shorter than that ((5.28 +/- 2.41)h) in the blank control group and that ((5.38 +/- 2.36)h) in the sham-acupuncture group, presenting statistically significant differences (all P < 0.05). In the latent phase of the 1st labor stage and the 2nd and 3rd stages, in the comparison of the blood pressure and the heart rate of the puerperas as well as the heart rate of fetus after EA, the bleeding 24 h after labor and 1 min Apger score of the newborns among three groups, there were no statistically significant differences (all P > 0.05).
EA at Sanyinjiao (SP 6) can shorten the duration of the active phase of the 1st labor stage. It is safe for either the puerpera or the fetus and can assist the parturition quality in clinic.
