聚乙烯醇泡沫负压伤口疗法在脊柱结核术后反复窦道不愈合中的应用

摘要

Objective To evaluate the therapeutic effect of negative pressure wound therapy (NPWT) by filling polyvinyl alcohol (PVA) foam in the deep cavity for repeated non-healing sinus of spinal tuberculosis. Methods From January 2008 to January 2011, 17 cases of repeated non-healing sinus of spinal tuberculosis after surgery were treated by sinus debridement and NPWT by filling PVA foam in deep cavity. Therapeutic efficacy and prognosis were observed. Results The wounds of patients were placed PVA foam for 10-25 d (15.7 d on average) and completely healed after 17-29 d (21.5 d on average). All patients were followed up from 6 to 30 months, and no recurrence of tuberculosis existed. Conclusion NPWT is an important healing tool for repeated non-healing sinus of spinal tuberculosis after surgery; and it plays a significant role in promoting healing wound, exhausting tuberculosis abscesses, and eliminating dead space.%目的 评价深腔填塞聚乙烯醇(polyvinyl alcohol,PVA)泡沫行负压伤口疗法(negative pressure wound therapy,NPWT)在脊柱结核术后治疗窦道不愈合中的效果.方法对2008年1月-2011年1月临床收治的17例脊柱结核术后反复窦道不愈合的病例,延窦遂行病灶清除联合深腔填塞PVA泡沫行NPWT,观察在院治疗效果和愈后复发情况.结果患者伤口安置PVA泡沫10-25 d,平均安置15.7 d,伤口完全愈合17-29 d,平均21.5 d.随访6—30个月,无结核病灶复发.结论 NPWT是脊柱结核术后反复窦道不愈合治疗中一项重要的手段,它在促进伤口愈合、结核脓肿排空、消灭脓肿死腔等方面起到了不可忽视的作用.
