目的探讨负压辅助闭合技术用于Ⅳ期压疮的疗效观察。方法将我院内外科210例Ⅳ期压疮患者随机分为两组:A组使用负压辅助闭合技术处理,B组使用湿性疗法处理。比较伤口处理15天、30天时伤口面积减小率、愈合计分、治疗时间。结果两组愈合时间比较差异有统计学意义(P<0.01)。两组愈合计分、伤口面积减小率,A组明显优于B组。结论负压辅助闭合技术用于Ⅳ期压疮,可促进伤口渗液引流,促进伤口愈合和缩短愈合时间的效果优于湿性疗法,对于有潜行和窦道伤口效果更为出色。
Objective To investigate the curative effect of negative pressure assisted closure technique on stage Ⅳ pressure ulcer. Methods 210 patients with stage Ⅳ pressure ulcer in our hospital were randomly divided into two groups: group A was treated with negative pressure assisted closure technique, and group B was treated with moist therapy. The wound area reduction rate, healing score and treatment time were compared between the 15th day and the 30th day. Results There was significant difference in healing time between the two groups (P <0.01). The healing scores and wound area reduction rate in both groups were significantly better in group A than in group B. Conclusions The negative pressure assisted closure technique is suitable for stage Ⅳ pressure ulcer, which can promote wound exudate drainage, promote wound healing and shorten the healing time than wet therapy, which is more effective for stealth and sinus wounds.
