Application of vacuum sealing drainage (VSD) in operation design of large area skin defect

Objective: To investigate the application of vacuum sealing drainage (VSD) in operation design of large area skin defect. Methods: Took technology of vacuum sealing drainage (VSD) to primary debridement and secondary sealing wounds treating 18 patients. In all patients, two cases were complete trauma of single lower extremity (area of skin defect 20% in the whole body surface area); Seven cases were trauma of single leg; Three cases were large area bedsore; Seven cases were trauma of single foot; Six cases were trauma of single arm; All patients' track of investigating were followed up for 6 to 12 months, on average of 9 months. Results: The technology of vacuum sealing drainage (VSD) promoted tissue growing of granulation were obviously, during ten days of vacuum sealing drainage (VSD) adsorption, granulation tissue had grown satisfied under the sponge in all patients, wound surface reduced obviously. The method could prevent infection, without any complication, it had provided advantageous requirement for secondary sealing wound. Conclusion: Vacuum sealing drainage (VSD) promotes granulation growing, draw forth completely, providing abundant base for sealing wound in the days to come, no influence healthy tissue of supplying blood, operation is simple and convenient, the trecting effect is reliable, it can shorten the course of treatment.
