OBJECTIVE: To observe the effect of electroacupuncture (EA) with different stimulation parameters on medicine-induced abortion. METHODS:One hundred and nine cases of early pregnancy who asked medicine-induced abortion were allocated to an EA group A (n = 37), an EA group B (n = 38) and a medication group (n = 34). Within 30-60 min after oral administration of Misoprostol, in the EA group A, EA was given at bilateral Hegu (LI 4) and Sanyinjiao (SP 6) with cluster waves of 100 Hz and in the EA group B, EA was given at Hegu (LI 4) for 20 min and then at Sanyinjiao (SP 6) for 5 min with continuous waves of 50 Hz. EA was not given to the medication group. The complete abortion rate, duration of eliminating embryonic sac, colporrhagia lasting time and abdominal pain condition were recorded. RESULTS: The complete abortion rate was 91.9% in the EA group A and 86.8% in the EA group B, which were higher than 82.4% in the medication group, with no significant differences between the 3 groups (P>0.05); the duration of eliminating embryonic sac and the colporrhagia lasting time in the two EA groups were significantly shorter than those in the medication group (P<0.05, P<0.01); alleviation of abdominal pain in the EA group B was better than the medication group (P<0.01) and the EA group A (P<0.05). CONCLUSION: Different stimulation parameters of EA have different effects on abortion.
