Comparison of the effect of simple small incision decompression and VSD negative pressure closure and drainage on venomous snake bite
Objective:To investigate the effect of simple small incision incision decompression and vacuum sealing drainage(VSD)negative pressure closure and drainage on the treatment of venomous snake bite site and limb swelling,so as to provide an effective and feasible treatment plan for the treatment of clinical complications.Methods:A total of 334 patients with venomous snake bite limb swelling were randomly divided into treatment group and control group,with 196 cases in the treatment group and 138 cases in the control group.The patients in both groups were treated with standardized comprehensive treatment at an early stage,the control group was trea-ted with traditional simple small incision and decompression,and the treatment group was treated with VSD nega-tive pressure closure and drainage,and the treatment effects of the two groups were compared and analyzed.Results:The length of hospital stay was shortened from the control group(4.72±2.00)days to the treatment group(2.25±1.17)days,and the medical expenses of the patients decreased from the control group(4 962.18± 918.92)yuan to the treatment group(2 845.77±580.48)yuan,the difference was statistically significant(all P＜0.01),and the cure rate of patients increased from 83.33％in the control group to 94.90％in the treatment group.Conclusion:The efficacy of VSD negative pressure closure drainage on the swelling and necrosis of venom-ous snake bite limb is better than that of simple small incision incision and decompression drainage.
