Research on the Clinical Efficacy of VSD Negative Pressure Drainage Technology Combined with Free Skin Graft in the Treatment of Large Area Skin Defect

Objective: To study the clinical efficacy of VSD negative pressure drainage technology combined with free skin graft in the treatment of large area skin defect of clinical curative effect. Methods: 65 patients with large area skin defects admitted in our hospital from April 2012 to October 2013 were chosen and randomly divided into the observation group(35 cases) and control group(30 cases). Patients of observation group were treated by VSD before surgery and after free skin grafting. Patients of control group were treated by traditional suppression of skin graft or traditional pressurized packaging technology. The skin graft survival time, skin graft survival, hospital days, switching frequency, pain score and family satisfaction were observed and compared between two groups. Results: Compared with the control group, the skin graft survival time of observation group was shorter, the flap survival rate was higher, the length of time was shorter, the switching frequency was less, the pain score of observation group was significantly lower, the family satisfaction was higher, the differences between the two groups had statistical significance(P0.05). Conclusion: Compared with the traditional suppression of skin graft or traditional pressurized packaging technology, the VSD negative pressure drainage technology combined with free skin graft was more effective in the treatment of large area skin defects, which was worth popularizing in clinical use.
