VSD负压引流联合纳米银敷料治疗3、4期压力性损伤中的应用对比研究

Comparative Application Study of VSD Negative Pressure Drainage Combined with Nano-Silver Dressing in the Treatment of Stage 3 and 4 Pressure Injuries

摘要: 目的：研究VSD负压引流联合纳米银敷料在3、4期压力性损伤感染创面中的应用效果，为3、4期压力性损伤感染创面的患者制定合理的护理方案、评价护理效果提供依据。方法：选取2019年3月~2021年3月一年时间中，在我院就诊的3、4期压力性损伤患者320例，并将其平均分为两组，即观察组与对照组。前者采用的治疗方式为VSD负压引流技术联合纳米银离子敷料；后者使用VSD负压引流技术进行治疗。两组进行数据对比，对比的因素有临床治疗效果、换药次数与费用、创面愈合与肉芽组织生长时间。结果：观察组上述因素都明显低于对照组(P < 0.05)，其临床治疗有效率(86.88%)显著高于对照组(59.38%, P < 0.05)。结论：采用VSD负压引流技术联合银离子技术对3、4期压力性损伤患者进行治疗，可以减少换药次数以此来节省费用，同时患者所承受的疼痛也有很大程度降低，并且创面愈合速度更快，综上所述，其临床应用价值较高，值得进行推广。

Abstract: Objective: To study the application effect of VSD negative pressure drainage combined with nano-silver dressing in stage 3 and 4 pressure injury infected wounds, so as to provide basis for formulating reasonable nursing plan and evaluating nursing effect for patients with stage 3 and 4 pressure injury infected wounds. Methods: A total of 320 patients with stage 3 and 4 stress injury admitted to our hospital from March 2019 to March 2021 were randomly divided into observation group and control group, with 160 cases in each group. The control group was treated with VSD negative pressure drainage, and the observation group was treated with VSD negative pressure drainage combined with nano-silver ion dressing. Pain degree, dressing change times, dressing change cost, wound healing time, granulation tissue growth time and clinical treatment effect were compared between the two groups. Results: The number of dressing change, cost of dressing change, wound healing time, pain degree and granulation tissue growth time in the observation group were significantly lower than those in the control group (P < 0.05). The clinical effective rate in the observation group (86.88%) was significantly higher than that in the control group (59.38%, P < 0.05). Conclusion: We use VSD negative pressure drainage technology to combine silver ion technology to treat patients with stress injuries 3 and 4, which can reduce the number of changes to save costs large extent, and the wound healing is faster, at the same time, the pain of the patient has been greatly reduced, and the wound healing is faster. In summary, its clinical application is worth promoting.
