目的探讨负压封闭引流技术（Vacaumstalingdrainage，VSD)治疗足背大面积皮肤撕脱伤的临床效果。方法对近1年来我院收治的足背大面积皮肤撕脱伤患者8例。采用筛孔状全厚皮片移植法修复，皮片表面用多聚乙烯醇明胶海绵材料覆盖封闭，24h不间断负压吸引(维持负压在40kPa)。结果平均使用VSD10d，5例皮片全部存活创面愈合，3例大部分皮片存活。经换药后，创面愈合，患肢运动功能及外观恢复良好。与对照组比较，在平均住院天数、植皮的愈合率、换药次数及总费用等方面差异均有统计学意义(P<0.05)。结论筛孔状全厚皮片移植法原位修复结合VSD处理足背皮肤撕脱创面能降低感染地发生，提高皮片存活率，是治疗足背皮肤撕脱伤较好的方法。“,”Objective To study the negative pressure closed drainage technology (Vacaumstalingdrainage, VSD) treatment foot back large areas of skin avulsion clinical ef ect. Methods last year were our foot large areas of skin avulsion eight cases of patients. The cribriform ful thickness skin piece of grafting repair, skin piece surface with polyvinyl alcohol gelatin sponge materials cover closed, 24 h uninterrupted pressure suction (maintaining negative pressure in forty kpa). Results The average use VSD10d, five cases of skin wound healing al survived piece, three cases of most of the flap survival. The dressing, wound healing, limb movement function and appearance good recovery. Comparing with control group, the average hospitalization days, skin graft healing rate, dressing number and total cost dif erences were statistical y significant (P<0.05). Conclusion cribriform ful thickness skin piece of grafting in situ repair VSD combined treatment foot skin avulsed wound can reduce infection to occur, improve skin piece of survival, is the treatment foot skin avulsion good method.
