Abstract

ABSTRACT To determine the clinical efficacy of Zuqing Xu ‘Wuduling’ powder for snake injury on the swelling of the affected limb bitten by Agkistrodon halys. Sixty-five patients with Agkistrodon halys bite were assigned to a treatment group (n = 35) or control group (n = 30). The treatment group was additionally given ‘Wuduling’ powder dressing locally based on the therapy to the control group with conventional Western medicine. Clinical efficacy and improvement of traditional Chinese medicine symptoms and signs in the two groups were evaluated. The treatment group showed a notably higher cure rate than the control group. After 3 days of therapy, the swelling and pain of the affected limb in the treatment group were greatly alleviated. Additionally, after 7 days of therapy, the swelling and pain of the affected limb in the treatment group were more greatly alleviated, and those in the control group were also alleviated. The comparison of the two groups during the same period showed more obvious alleviation of swelling and pain in the treatment group than that in the other. Moreover, the treatment group experienced notably shorter disappearing time of swelling and pain than the control group. After treatment, the levels of CRP, TBIL, Cr, ALT, AST, BUN, CK, LDH and CK-MB in both groups declined notably, with notably lower levels of them in the treatment group than those in the other. Zuqing Xu ‘Wuduling’ powder for snake injury can substantially alleviate the swelling and local pain of affected limbs bitten by Agkistrodon halys.
