Abstract：Objective To observe the effect of two different kinds of dressing for vacuum drainage in limb skin grafting.Methods In this study,70 patients with skin and soft tissue defect were treated with skin grafting from Jan.2011 to Feb.2014.Among them,32 patients were treated with negative pressure drainage dressing (Group A) and the other 38 patients were treated with vacuum sealing drainage (Group B).The dressings were removed after 1 week of treatment .The survival rate of skin graft ,operation time ,wound healing time and the average hospi-talization time were recorded and analyzed and the therapeutic effects were compared by T test and χ2 test.Results The survival rate of skin graft in Group A was significantly higher than that of Group B (P<0.05),and the opera-tion time in Group A was significantly shorter than that of Group B (P<0.05) while the wound healing time and the time in hospital had no statistical differences (P>0.05).Conclusion Both kinds of dressing have good effect on the coverage of skin grafting .Compared with vacuum sealing drainage dressing ,negative pressure drainage dressing has the advantage of improving the survival rate of thin skin graft and reducing the operation time .We can choose the dressing based on the condition of the patient .
