Clinical observation of continuous skin distraction technique combined with vacuum sealing drainage in the treatment of deep wounds

Objective To investigate the clinical effect of continuous skin distraction technique combined with vacuum sealing drainage (VSD) on the treatment of deep wounds. Methods From May 2015 to May 2018, 20 patients with deep wound in different parts were selected from the Department of Emergency Medicine, Shanxi Bethune hospital, including 10 cases of trauma, 7 cases of pressure sore and 3 cases of infection wound. According to the situation of wounds, continuous skin distraction combined with VSD was applied after debridement. The wound healing time was observed and recorded. The Vancouver scar scale of all the patients was used to evaluate the wound healing quality. Results The wounds of 20 patients were healed well after continuous stretch of skin and VSD treatment. The average healing time of 5 patients with wound size of 2 cm×2 cm to 3 cm×4 cm was 20 days, the average healing time of 8 patients with wound size of 5 cm×5 cm to 8 cm×10 cm was 22 days, and the average healing time of 7 patients with wounds ranging from 10 cm×15 cm to 15 cm×20 cm was 30 days. The average vancouver scar scale score of 3 months after wound healing was 3.8 point. Conclusion The application of continuous skin distraction combined with VSD technology to treat deep wounds not only can obtain satisfactory clinical results, but also has the advantages of simple operation and small trauma, which is worth promoting.
