负压封闭引流在胸腰椎后路内固定术后早期伤口深部感染治疗中的应用

目的探讨负压封闭引流(Vacuum sealing drainage,VSD)技术在胸腰椎后路内固定术后早期伤口深部感染治疗中的应用。方法回顾性分析我院2008年1月~2010年12月胸腰椎后路内固定术后深部感染的12例患者,应用敏感抗生素,保留内固定、彻底清创并结合负压封闭引流治疗,二期缝合。结果 12例病人经过1~3次负压引流后感染得到控制,均顺利行二期创面缝合。随访9~36个月,患者感染均未再复发。结论对于胸腰椎后路内固定术后早期的深部感染,应用敏感抗生素,彻底清创并结合负压封闭引流可以有效控制感染,利于伤口的早期愈合,但是否保留内固定物仍需进一步的研究。

Vacuum sealing drainage for deep infection after thoracolum- bar posterior internal fixation

Objective To investigate the efficacy of Vacuum sealing drainage （VSD） for deep infection after thorac- olumbar posterior internal fixation. Methods From January 2008 to December 2010, 12 patients with deep infection after thoracolumbar posterior internal fixation were treated, all of them underwent combined debridement with implant retained, vacuum sealing drainage and intravenous antibiotic therapy, then the wound was closed. Results All the patients were treated by VSD for one to three times before the wound closure, all the patients were followed up for 9 to 36 months and all the cases were cured. Conclusion For the patients with early-onset deep infections after thoracolumbar posterior internal fixation, the application ofsensitive antibiotics, thorough debridement combined with vacuum sealing drainage can effectively control the infection, and conducive to wound healing, but whether the implant retained still need further research.
