负压封闭引流技术联合银离子敷料治疗骨科感染性创面的临床研究

Clinical study of vacuum sealing drainage combined with silver ion dressing in the treatment of orthopedic infectious wound

目的 探讨负压封闭引流技术(vacuum sealing drainage, VSD)联合银离子敷料治疗骨科感染性创面的临床效果。方法 2019年10月~2021年6月期间符合筛选标准的病人30例,随机分为实验组和对照组各15例,对照组采用常规VSD治疗,实验组采用VSD联合银离子敷料治疗。1周后,比较两组创面细菌清除率、肉芽组织覆盖率,记录两组创面愈合时间及治疗总有效率。结果 治疗1周后,实验组细菌清除率为(97.90±1.34)%,对照组为(89.58±1.26)%,两组比较差异有统计学意义(P<0.05);实验组肉芽组织覆盖率为(89.59±2.05)%,对照组为(76.02±1.69)%,两组比较差异有统计学意义(P<0.05);实验组创面愈合时间为(17.67±1.18)天,对照组为(22.33±2.09)天,两组比较差异有统计学意义(P<0.05);实验组治疗有效率为93.33%,对照组为73.33%,两组比较差异有统计学意义(P<0.05)。结论 对于骨科感染性创面,采用VSD联合银离子敷料治疗效果满意,能有效减少创面感染、促进创面愈合。

Objective To investigate the clinical effect of vacuum sealing drainage(VSD) combined with silver ion dressing to treat infectious orthopedic wounds.Methods 30 patients who met the screening criteria from October 2019 to June 2021 were selected and randomly divided into experimental group and control group, 15 patients in each group.The control group was treated with conventional VSD,and the experimental group was treated with VSD combined with silver ion dressing.One week later, the bacterial clearance rate and granulation tissue coverage rate of the two groups were analyzed and compared.The wound healing time and total effective rate of the two groups were recorded and statistically analyzed.Results After one week, the bacterial clearance rate of the experimental group was(97.90±1.34)%,which was significantly higher than that of the control group(89.58±1.26)%(P<0.05).The coverage rate of granulation tissue in experimental group was(89.59±2.05)%,which was significantly higher than(76.02±1.69)% in control group(P<0.05).The wound healing time of the experimental group was(17.67±1.18)days, which was significantly shorter than that of the control group(22.33±2.09)days(P<0.05).The effective rate of the experimental group was 93.33%,higher than that of the control group(73.33%),and the difference was statistically significant(P<0.05).Conclusion For infectious orthopedic wounds, VSD combined with silver ion dressing can effectively reduce wound infection and promote wound healing.
