摘要目的 探讨蓝光治疗烧伤残余创面的疗效. 方法 选择2013年4月-2013年10月大面积烧伤残余创面患者64例,烧伤面积30％ ～ 80％,残余创面面积0.5％～3％,按随机数字表法分为对照组(32例)和治疗组(32例).对照组采用聚维酮碘纱布换药治疗,治疗组在对照组治疗基础上,采用蓝光照射治疗.比较两组治疗后5d创面感染控制率、治疗后10 d创面细菌清除率、创面愈合情况及创面总愈合时间. 结果 治疗后5d,治疗组感染控制19例,基本控制9例,控制不佳4例,感染控制率为88％;对照组分别为8例、14例、10例,感染控制率为69％(P＜0.05).治疗后10 d,治疗组、对照组创面细菌清除率分别为81％、63％ (P ＜0.05);治疗组创面治愈20例,显效9例,好转2例,无效1例,创面愈合率为91％,对照组分别为5例、14例、8例、5例,创面愈合率为59％ (P ＜0.05);治疗组、对照组创面愈合时间分别为(12.5±4.5)d、(18.5±6.5)d(P＜0.05). 结论 蓝光可有效杀灭烧伤残余创面细菌,加快创面愈合速度,是治疗烧伤残余创面的新型方法,值得临床推广.

abstractsObjective To investigate the effect of blue light in treating the residual burn wounds.Methods Sixty-four massive burned patients with residual wounds (burn area of 30％-80％ total body surface area and residual wound of 0.5％-3％) treated between April 2013 and October 2013 were allocated to control group (32 cases) and treatment group (32 cases) according to the random number table.In control group,the wounds were dressed with povidone-iodine gauze.And,except for this,patients in treatment group were treated with blue light therapy.Between-group comparison was made on infection control,bacterial clearance rate,wound healing,and healing time.Results On the fifth day after treatment,treatment group showed infection control in 19 cases,basic control in 9 cases and non-control in 4 cases,with the infection control rate of 88％;on the contrary,control group showed infection control in 8 cases,basic control in 14 cases and non-control in 10 cases,with the infection control rate of 69％ (P ＜ 0.05).On the tenth day after treatment,bacterial clearance rate between treatment and control groups was 81％ and 63％ respectively (P ＜ 0.05).Rate of wound healing was 91％ in treatment group including 20 cases cured,9 significantly improved,2 improved and 1 remained unchanged,but was 59％ in control group with 5 cases cured,14 significantly improved,8 improved and 5 remained unchanged (P ＜ 0.05).Healing time was (12.5 ± 4.5) days in treatment group versus (18.5± 6.5)days in control group (P ＜ 0.05).Conclusion Blue light can effectively kill the bacterial on residual burn wound and accelerate wound closure and hence is a new method to treat residual burn wounds,worthy of clinical application.
