OBJECTIVE: To evaluate the effects of Jidesheng anti-venom used externally for skin and soft-tissue necrosis from Chinese cobra bite.METHODS: A retrospective review was performed according to the clinical data recorded from January 2002 to December 2012. A total of 126 patients(116 females and 10 males) with skin and soft-tissue necrosis due to Chinese cobra bite were divided into two groups. The control group was treated externally with 40% glyceride magnesium sulfate(n=52), and the treatment group was given Jidesheng anti-venom externally(n=74). The data collected included maximum local necrotic area of skin and soft tissues, de-tumescence time, healing time,and skin-grafting rate.RESULTS: There were no significant differences in gender, age, and disease condition between the control and treatment groups(P>0.05). No statistically significant difference was found in de-tumescence time between the two groups(P>0.05). The maximum local necrotic area of skin and soft tissues was(19.9 ± 7.3) cm2in the treatment group,while it was(23.3±6.4) cm2in the control group.The healing time of the treatment group was shorter than that of the control group [(32.1 ± 3.7) vs(34.4±4.5) days)] The skin-grafting rate in the treatment group was lower than that of the control group(10.81% vs 25.00%). There were statistically significant differences in maximum local necrotic area of skin and soft tissues, healing time, and skin-grafting rate between the control and treatment groups(all P
