银离子水胶体油纱结合自黏性聚氨酯泡沫敷料对供皮区创面愈合的疗效研究

目的 发现并改进一种促进大面积取皮后供皮区创面愈合的治疗方法.方法 将2014年1月至2015年12月需要在大腿上切取中厚皮片的患者共40例,随机分为试验组和对照组.取皮术后试验组采用银离子水胶体油纱和自黏性聚氨酯泡沫敷料覆盖创面;对照组采用传统的凡士林油纱和无菌纱布、棉垫覆盖创面,并用绷带加压包扎.对比术后局部感染的情况、首次换药时的疼痛评分、术后至完全愈合期间的换药次数、完全愈合所需的时间及术后两周时未愈合面积的百分比,并用SPSS17.0做统计学分析.结果 试验组无一例感染,对照组有两例发生感染,创面分泌物培养均为铜绿假单胞菌,经换药治疗痊愈.试验组在首次换药时的疼痛评分、完全愈合前的换药次数及愈合时间上均显著优于对照组,其差异均有统计学意义(U=81.5,P=0.001;U=109.5,P=0.011;t=0.769,P＜0.001).结论 采用银离子水胶体油纱结合自黏性聚氨酯泡沫敷料有助于促进供皮区创面愈合,减少患者痛苦,且该方法换药次数少,操作简便,术后两周内供皮区基本愈合,值得进一步推广使用.

Efficacy of Physiotulle Ag combined with Allevyn foam dressing for skin graft donor sites

Objective To explore a new method for improving healing of skin graft donor sites.Methods A total of 40 patients who needed intermediate thickness skin graft from thigh,from January 2014 to December 2015,were randomly devided into experiment group and control group.Skin graft donor sites of the experiment group were covered with Physiotulle Ag and Allevyn foam dressing,while donor sites of the control group were covered with petrolatum impregnated gauze,sterile gauze,and compression bandage.Postoperative infection rate,pain scoring during the first dressing change,time of dressing change between operation and complete healing,duration for complete healing,and the area of non-healing two weeks after operation were compared and statistical analysis was performed with SPSS17.0.Results There was no infection in the experiment group.Two patients developed infection in the control group,with wound exudate culture positive for pseudomonas aeruginosa,and the wounds healed after dressing change.The experiment group was significantly better than that of the control group in pain scoring during the first dressing change,time of dressing change between operation and complete healing,duration of complete healing (U=81.5,P=0.001;U=109.5,P=0.011;t=0.769,P＜0.001).Conclusions The Physiotulle Ag combined with Allevyn foam dressing can enhance healing of skin graft donor sites,alleviate pain of the patient,and reduce dressing change.This method is easy to perform,and skin graft donor sites heal well in two weeks,which may lead a prospected application.
