摘要目的 评价微等离子束技术(micro-plasma technology,MPT)与铒激光像束模式(2940 nm Er∶YAG laser)治疗陈旧性轻度和中度烧伤瘢痕的临床疗效、适应证及不良反应.方法 265例随机分为2组,MPT组136例,Er∶YAG组129例.分别治疗2～6次.结果 MPT组与Er∶YAG组的有效率分别为73.52％和44.95％,治愈率分别为28.67％和15.50％,两组总体疗效比较,差异有统计学意义,其中172例轻度瘢痕患者,MPT组与Er∶YAG组的有效率分别为78.52％和67.09 ％;MPT组疗效虽略优于Er∶YAG组,但差异无统计学意义；93例中度瘢痕患者,MPT组与Er∶YAG组的有效率分别为62.79％和10.00％,MPT组疗效显著优于Er∶YAG组,两组比较差异有统计学意义.结论 MPT和Er∶YAG治疗轻度烧伤瘢痕均有可靠疗效,且不良反应小.治疗中度瘢痕MPT的疗效显著优于Er∶YAG.

abstractsObjective To compare the effectiveness,indications and side effect between microplasma technology (MPT) and 2940 nm Er ∶ YAG laser for treatment of burn scar.Methods 265 patients with hypertrophic scar were treated with MPT (MPT group,N=136) and Er ∶ YAG laser (Er ∶ YAG laser group,N=129).The patients were treated 2-6 times.Results The significant response rate was 73.52 ％ and 44.95 ％ in MPT group and Er ∶ YAG laser group; the cure rate was 28.67 ％ and 15.50 ％ in MPT group and Er ∶ YAG group,respectively.There was no statistically significant difference between two groups (P＞0.05).For moderate burn scar patients (93 cases),the significant response rate was 62.79 ％ and 10.00 ％ in MPT group and Er ∶ YAG laser group,respectively.There was significant difference between two groups (P＜0.05).Conclusions MPT and Er ∶ YAG laser has been proven to be effective and safe for the treatment of burn scar.The effectiveness of MPT is superior to Er ∶ YAG laser in treatment of moderate burn scar.
