Clinical Studys for the Treatment of Complex Wounds by Improved Vacuum Sealing Drainage

Objective: To evaluate the clinical efficacy and benefits of the treatment of complex wounds with improved vacuum sealing drainage(VSD).Method: 46 cases of patients with complex wounds in our hospital from January 2005 to December 2008 as the control group,52 cases of patients received from January 2008 to December 2011 as an experimental group.The control group use dressing method with the conventional wiping drug treatment,and the experimental group treated with improved VSD,all patients basal granulation to be grafting permission or flap for reconstruction.Then compared two group's treatment effect.Result: 40 patients in the experimental group received once modified VSD treatment and 12 patients received twice VSD treatment,the VSD average treatment time was(17.8 ± 1.3) days.38 cases of basal growth of granulation skin graft surgery,and postoperative survived;14 patients with bone or tendon exposed,granulation can not cover the wound,the line flap for reconstruction,and postoperative survived successfully.The control group's average treatment time was(37.6 ± 1.7) days before they meet the conditions of skin graft or flap transplantation,8 patients exposed serious bone or tendon,average dressing 21.5 times,the average duration of treatment was(42.6 ± 1.9) days;compared with the time between two groups of treatment(P 0.05),the difference was significant.Conclusion: Improved VSD is an effective technology treatment for complex wounds,In the treatment of bone or tendon exposure complex wounds,the technical performance of the incomparable advantages of traditional treatment methods.Not only shorten the treatment cycle,but also reduce the suffering of patients and treatment costs,most importantly,the main therapeutic effects have significantly improved,and can be widely used clinical.
