高负压封闭引流技术治疗脊柱内固定术后感染的临床疗效

目的：评价高负压封闭引流（VSD）技术治疗脊柱术后感染的临床疗效。方法：应用VSD技术治疗脊柱术后感染19例。每例患者应用VSD技术处理创面1～4次，每次引流5～7d。结果：19例患者中7例经1次引流术后创面清洁，肉芽组织生长满意，即予一期缝合，10例行2次引流后直接缝合伤口，1例行3次引流后缝合伤口，1例行4次引流后死腔方消灭，停用VSD，常规换药6周后创面愈合。19例患者中12例内固定得以保留，7例患者去除内固定后创面愈合。结论：VSD技术治疗脊柱术后感染具有较好的临床疗效。

Clinical effect of vacuum-sealing drainage in treating infection after operation on spine

Objective：To assess the therapeutic effect of vacuum-sealing drainage （VSD） in treating infection after operation on spine. Methods： Nineteen patients suffering from infection after spinal operation were treated with VSD. Every patient was debrided with VSD 1 to 4 times,and draining was kept for 5 to 7 days each time. Results： The wound surface became clean and granulation tissue grew well after drainage for 1 time in 7 patients,and the wound were closed with sutures and healed at first intention. The wounds were sutured after drainage for 2 times in 10 patients,and for 3 times in 1 patient. In 1 patient, the dead space disappeared and the wound surface became flat after drainage for 4 times, then the VSD was stopped, the wound finally healed after 6 weeks. The internal fixation was retained in 12 patients,and it was removed in 7 patients. Conclusion： VSD is superior to traditional method in treating infection after spinal operations,and the effect is satisfactory.
