目的探讨磨痂保留变性真皮自体皮片移植修复手深度烧伤的可行性。方法31名烧伤患者,双手为深Ⅱ、混合度(混合深Ⅱ度、Ⅲ度)烧伤。在同体中设立磨痂组(31只手),用自制的医用烧伤磨痂器磨痂保留变性真皮,移植自体薄中厚皮片;削痂组(31只手),上止血带,用辊轴刀削痂,移植自体中厚皮片。观察两组患者术中出血量、手术时间、皮片成活率、供皮区愈合情况、组织病理学、自制医用烧伤磨痂器的使用情况、外形与功能情况。结果磨痂组术中失血量与削痂组比较无差异性(P0.05);手术时间明显缩短(P

Objective To study on feasibility of dermabrasion in repair of deeply burned hands with the preservation of denatured dermis and auto-skin grafting. Methods 31 burn patients (62 hands) with deeply partial thickness and full thickness burn of hand. In dermabrasion group (31 hands), the wounds were treated by dermabrasion and grafted with auto intermediate-split-thickness graft with the preservation of denatured dermis by self-made abraded excision instrument. In tangentile excision group (31hands), under the...
