ABSTRACT

Objective To compare the therapeutic effect of conventional treatment and conventional treatment plus external application of Shuangbai Powder for patients with wounded limb injured by venomous snake. Methods One hundred patients bitten by venomous snake were randomized into treatment group and control group, 50 cases in each group. The control group was given conventional treatment including repeatedly washing the wound with hydrogen peroxide, debriding the wound, letting blood and draining toxicity, local blocking with chymotrypsin, wet packing the wounded limb with magnesium sulfate, and injection with anti-venomous serum, tetanus antitoxin, antibiotics, furosemide and energy mixture. The treatment group was given external application of Shuangbai Powder on the basis of the treatment for the control group. Both groups were given the comprehensive nursing of psychological nursing, wound nursing, dietary nursing, defecation nursing and functional nursing. The swelling-subsiding time for the wounded limb and pain scores of visual analogue scale (VAS) in the two groups were compared. Results(1) After treatment, swelling-subsiding time for the wounded limb of the treatment group was shorter than that of the control group, the difference being statistically significant (P < 0.05). (2) After treatment for 4 days and at the end of the treatment, VAS scores of the two groups were decreased compared with those before treatment(P < 0.05), and the decrease of VAS scores in the treatment group after treatment for 4 days was superior to that in the control group (P < 0.05). Conclusion The conventional treatment plus external application of Shuangbai Powder is an effective therapy for patients with wounded limb injured by venomous snake by shortening swelling-subsiding time and relieving pain for the wounded limb .
