Abstract:Objective To compare the effect of electroacupuncture preconditioning with different frequencies on anal pain after milligan-morgan hemorrhoidectomy. Methods A total of 120 patients with mixed hemorrhoids were randomly divided into an electroacupuncture group A(dilatational wave, 2 Hz/100 Hz in frequency), an electroacupuncture group B(continuous wave, 2 Hz in frequency) and an electroacupuncture group C(continuous wave, 100 Hz in frequency), 40 cases in each group. Electroacupuncture at Xialiao(BL 34) and Chengshan(BL 57) was applied with tolerant intensity for 30 min before operation in all groups. The number of additional anesthetic drugs in the 3 groups, the visual anal pain score(VAS) and limb activity score at 4, 12, and 24 h after operation, the maximum VAS score within24 h after surgery and oral dose of aminophenol dihydrocodeine were compared. Results The number of additional anesthetic drugs in the electroacupuncture group A, the electroacupuncture group B and the electroacupuncture group C were 4, 5, 4 respectively, and there was not statistically significant(P>0.05). There was no significant difference in the anal pain VAS score and limb activity score at 4 h after operation among the 3 groups(P>0.05), at the 12 h after operation, the VAS scores and limb activity scores in the electroacupunctures group A and B were lower than those in the electroacupuncture group C(P<0.05), at 24 h after operation, the VAS score and limb activity score in the electroacupuncture group A were lower than those in the electroacupuncture group B and C(P<0.05), the maximum VAS score within 24 h and oral dose of aminophenol dihydrocodeine within 24 h after operation in the electroacupuncture group A were lower than those in the electroacupuncture group B and C(P<0.05). Conclusion Different frequency electroacupuncture preconditioning has the effect of alleviating anal pain after milligan-morgan hemorrhoidectomy. The analgesic effect of electroacupuncture with different frequencies is different. The electroacupuncture analgesic effect of2 Hz/100 Hz dilatational wave is better than 2 Hz and 100 Hz continuous waves.
