Application of vacuum sealing drainage in treating large avulsion injuries of limbs / 中国骨伤

<p><b>OBJECTIVE</b>To investigate the therapeutic effectes of vacuum sealing drainage (VSD) technique and reattachment of avulsed skin in treating avulsion injuries of limbs.</p><p><b>METHODS</b>A retrospective analysis was done on 25 patients suffering from avulsion injuries of limbs, who were treated with vacuum sealing drainage and reattachment of the avulsed skin. Among the patients, 19 patients were male and 6 patients were female, ranging in age from 21 years to 57 years, with an average of 41 years. After debridement, the patients got reattachment of skin graft with subdermal vascular network or split-thickness skin graft, and the wound surface was covered with polyvinyl sponge. VSD was removed after 7 to 14 days. The color, survival rate and sensory function of the skin were observed after operation.</p><p><b>RESULTS</b>All the wounds infection was controlled with VSD. The skin survival rate was more than 96% in 16 cases, more than 90% in 7 cases, and skin edge of 2 cases had little necrosis but rehabilitated after dress-changing. The reattached skins had almost normal skin color, soft and abrasion resistant, satisfactory sensory function, and no compression ulcer was observed after 4 weeks.</p><p><b>CONCLUSION</b>VSD combined with graft with subdermal vascular network or split-thickness skin graft helps to promote wound drainage, reattachment of skin, and decrease infection. It is an effective method in treating avulsion injuries of limbs.</p>

Use of vacuum sealing drainage and mesh grafting in treating defects of skin and soft tissue in foot / 中国骨伤

<p><b>OBJECTIVE</b>To explore the therapeutic effectiveness of vacuum sealing drainage (VSD) technique and mesh grafting in treating defects of skin and soft tissues in foot.</p><p><b>METHODS</b>A retrospective analysis was done on 17 cases (11 male and 6 female) suffering from defects of skin and soft tissues in foot, which were treated by vacuum sealing drainage and mesh grafting. The age of patients was from 18 to 67 years with an average of 43 years. The wound surface was filled with polyvinyl alcohol gelatin sponge after debridement and continuous negative pressure drainage was taken for 24 h. After 7 days, granulation tissue growing mesh grafting was performed and to observe the skin colour, survival rate and feet function.</p><p><b>RESULTS</b>All the infection of wounds was controlled with VSD for 1 to 3 times. Skin survival rate of 14 cases more than 98%, 2 cases more than 95%; skin edge of 1 case had little necrosis, but foot function obtained rehabilitation after dress-changing.</p><p><b>CONCLUSION</b>Vacuum sealing drainage (VSD) technique and mesh grafting is effective methods for the treatment of defects of skin and soft tissues in foot and is worthy generalization and application.</p>
