负压引流联合纳米银敷料治疗感染切口的临床研究

Clinical Study on the Treatment of Infection Incisions by Negative Pressure Drainage Combined with Nano Silver Dressing

目的:探讨负压引流联合纳米银敷料治疗手术后感染切口的临床疗效。方法:根据自愿原则,将60例胃肠手术术后切口感染的患者分为单纯银离子敷料组、单纯负压吸引组和联合应用组,各20例。比较三组治疗后伤口愈合时间、换药次数、术后费用、术后住院天数及不同时段的C反应蛋白、白细胞数、体温、伤口细菌计数和疼痛评分。结果:联合应用组的各项指标均优于单纯银离子敷料组和单纯负压吸引组,比较差异均有统计学意义(P<0.05)。结论:负压吸引联合银离子敷料治疗相比单独运用银离子敷料或负压吸引能更有效地减轻伤口局部炎症,控制手术切口感染,促进伤口愈合,减轻患者疼痛,降低住院费用。

Objective：To evaluate the negative pressure drainage combined with nano silver dressing to promote the clinical effect of healing of incision infection.Method：According to the voluntary principle,60 patients with gastrointestinal surgery incision infection were divided into pure silver ion dressings group,pure negative pressure drainage group and combined group,20 cases in each group.After treatment,the wound healing time,number of dressing change,postoperative cost,postoperative hospitalization days,at different times of the CRP,leukocyte count,body temperature,wound bacterial counts and pain scores between three groups were compared.Result：The indexes of combined group were better than those of pure silver ion dressing group and pure negative pressure drainage group,the differences were statistically significant（P0.05）.Conclusion：Negative pressure drainage combined with silver ions dressing therapy compared with the single use of silver ion dressings or negative pressure can attract more effectively reduce the local inflammation,wound control incision infection,promote wound healing, reduce patient pain,reduce hospitalization expenses.
