Clincal Research Of Treatment By Vacuum Sealing Drainage (VSD) For Lower Extremity Soft Tissue Wound

Objective:1 Report the clinical effects of treatment the complicated skin and soft tissue of traumatic lower limb defects with vacuum sealing drainage.2 Analyze advantages and disadvantages of vacuum sealing drainage.3 To investigate the points and notes for vacuum sealing drainage.Methods:1.1 Case Selection:1.1.1 Selection criteria:Before the vacuum sealing drainage,within 6-8 hours after injury the cases treatment by the emergency debridement surgery or fracture fixation operation.The formation of lower extremity wounds is due to the skin and soft tissue necrosis after emergency surgery or that it is difficult to suture the wound during the emergency surgery.1.1.2 Wounds should be at least 5cm×5cm.From cost considerations, even if can not be closed during the emergency surgery the wound should not be too small to use the vacuum sealing drainage.1.2 Case Information:Choose skin and soft tissue defect of lower limb 9 patients,in January 2009 to January 2010 period by Taihe Hospital of Shiyan City in Hubei province.Include 7 males and 2 females,aged 17-62 years old.Injury reas-ons:traffic accident in 6 cases,1 case bruise, burn in 1 case,1 case of crash injury.Vacuum sealing drainage materials:including medical foam materials, multiside hole drainage, semipermeable membrane of paste,vacuum suction source.Design principles with the medical side of the foam wrap and more drainage holes, medical foam was placed in drainage area, and then paste the permeability of thin films using closed drainage area will be isolated, then the high negative pressure drainage tube source, forming a efficient drainage system. Surgical Methods:After debridement the wound and stop bleeding, foam dressing was cut and stitched according to wound size.The wound was covered with dressing, then closed the wound with semipermeable membrane, the material silicone tube with suction device is connected. Depending on whether drainage tube patency take appropriate measures, if necessary, replace the dressing.Results:Observation of the wound after dressing removal project:①wound dry, clean, non-necrotic tissue and exudate;②wound edema;③fresh granulation tissue, pink granular, easy to touch the bleeding;④wounds can be skin graft or flap transposition successfully.It should also pay attention to whether the fever, pain tolerance, et.After treatment by vacuum sealing drainage,9 cases were different degrees of reduced wound, granulation tissue was fresh with flat surface, capillary rich, tissue had no edema or exudate,infection was controlled. Less granulation tissue growth in bone exposure,the exposed tendon department.2 cases replaced dressing as more wound secretion,1 case of drain plug results in systemic fever.3 cases of wound drainage in patients larger the block, one case of smooth even after washing,dressing changeConclusion:Vacuum sealing drainage is a new method of wound treatment.The technology is simple, easy to master and curative effect. Improve the treatment of frequent replacement of the traditional wound dressings ways.Reduce the pain of patients by dressing.Dressing to reduce the pain of patients,prevent and limit the spread of infection,reduce local edema, improve local blood circulation and promotes the growth of granulation tissue.For those exposed and bone exposed wounds,vacuum sealing drainage also promote granulation tissue from the peripheral part of the coverage, promoting wound repair, so that the wounds became narrow bring convenience to the late skin graft or flap transposition.
