负压封闭引流术治疗胸腰椎病变术后切口感染的临床疗效

Clinical efficacy of vacuum sealing drainage in the treatment of postoperative wound infection of thoracolumbar vertebral body disease

目的：观察负压封闭引流（ VSD）治疗胸腰椎病变术后切口感染的临床疗效。方法对54例胸腰椎病变术后切口感染患者分别采用置管冲洗引流（对照组,23例）和VSD（ VSD组,31例）治疗。比较两组抗生素应用时间、创口局部治疗时间、引流管阻塞情况,创口愈合情况,观察VSD副反应,评估VSD的疗效。结果54例患者均获随访,时间6～5个月。抗生素应用时间：对照组（20.1±5.6）d,VSD组（14.1±2.1）d；创口局部治疗时间：对照组（25.2±6.2）d,VSD组（15.0±4.6）d；引流管阻塞次数：对照组13次（13/33）,VSD组11次（11/81）；创口愈合情况：对照组15例（15/23）,VSD组29例（29/31）。两组上述指标比较差异均有统计学意义（P＜0.05）。 VSD组出现皮肤发红、发痒5例,皮疹3例。结论 VSD治疗胸腰椎病变术后切口感染能缩短感染伤口治疗时间,促进创口愈合。

Objective To observe the clinical efficacy of vacuum sealing drainage （ VSD） in the treatment of postop-erative wound infection of thoracolumbar vertebral body disease. Methods 54 cases with postoperative incisional in-fection of thoracic lumbar spine surgery were respectively treated by irrigation-suction（control group,23cases）and VSD（VSD group,31cases）. The antibiotics applying time, the wound treatment time, drainage tube blockage situa-tion, the wound healing situation, VSD side reaction and other indexes were compared and retrospectively analyzed to evaluate the efficacy of VSD. Results 54 cases were followed up for 6~15 months. The antibiotics treatment time （20. 1 ± 5. 6）d in control group and（14. 1 ± 2. 1）d in VSD group, the tresis vulnus treatment time（25. 2 ± 6. 2）d in control group and（15. 0 ± 4. 6） d in VSD group, drainage tube blockage 13 times（13/33） in control group and 11 times（11/81）in VSD group, tresis vulnus was healed in 15 cases （15/23） in control group and 29 cases（29/31） in VSD group. These differences had statistical significance （ P 〈0. 05 ） . VSD group had 5 cases of skin redness and tickle, 3 cases of rash. Conclusions VSD can effectively shorten the wound infection treatment time and promote wound healing in the treatment of postoperative wound infection of thoracolumbar vertebral body disease.
