Objective To assess the preemptive analgesia effect of catgut implantation in Chengshan(BL 57) area on hemorrhoid operation-induced pain and the security

so as to find a new method for easing post-operative pain of hemorrhoid.Methods A total of 120 cases of mixed hemorrhoids patients were randomly divided into the catgut implantation group and me-dication group(n=60).In implantation group

a piece of catgut was embedded into bilateral BL 57 acupoint area half an hour before surgery.Patients of the medication group were asked to orally take Tramadol Hydrochloride Capsules(100 mg) after the surgery.The pain score of mixed hemorrhoids patients was evaluated 5

24

48

72 and 96 h after operation by using visual analogue scales(VAS).The complications

analgesics use and adverse reactions were recorded simultaneously.Results Comparison between two groups showed that the VAS scores of the catgut implantation group at 5

24

48

72 and 96 h after operation were significantly lower than those of the medication group(P<0.05).The incidence of complications of uroschesis and hydroncus

adverse reactions of nausea

vomiting and vertigo

and the number of patients using Sauteralgyl were significantly lower in the catgut implantation group than in the medication group(P<0.05).Conclusion Catgut implantation at BL 57 can effectively relieve the postoperative pain

reduce postoperative adverse reactions and complications in mixed hemorrhoids patients.
