薄化深度烧伤坏死层的方法与疗效观察

目的：观察自制创面磨削器薄化坏死层与MEBT配合应用治疗烧伤的临床效果。方法：用骨科手持电钻和磨皮柱状磨头组合制成创面磨削器。选择相对标准的深Ⅱ度深型和浅Ⅲ度烧伤各30例，行自身对照。在同一部位，同一深度分别应用MEBT 磨削(称薄化组)和单纯MEBT(单纯MEBT组)对比观察，比较创面液化开始时间、液化结束时间及创面愈合时间。结果：MEBT 磨削方法使液化时间、液化结束时间及创面愈合时间提前。结论：MEBT 磨削能较早地使生命物质：MEBO激发潜能干细胞，使创面提前愈合。

A method for thinning the necrotic tissue in deep burn wounds and its effect on wound healing

Objective: To observe the efficacy of an abrasive machine in thinning the necrotic tissue in deep burn wound combined with MEBT treatment. Method: 30 cases of deep 2 nd degree burn and 30 cases of superficial 3 rd degree burn were selected to enter the experiment. Each patient had parts of the wounds treated with MEBT + thinning the necrotic tissue using the abrasive machine (group A) and parts of the wounds treated with MEBT alone (group B). A comparison of the efficacy of the 2 groups was made, including the starting and finishing time of liquefaction and wounding healing time. Result: The healing time of the wounds treated with MEBT + thinning the necrotic tissue using the machine was shorter than those treated with MEBT alone. Conclusion: MEBT + abrasion treatment can help the biologically active substance in MEBO activate the stem cells so that the wounds can heal more quickly.
