电接触烧伤是人体直接与电源接触引起的组织凝固性坏死,其面积不大但较深,早期清除坏死组织将使感染机会减少,由于电接触烧伤的组织坏死范围早期不易肯定,皮肤表面损伤虽小,但坏死组织深在。同时肌肉坏死的范围和分界面极不整齐,同一块肌肉的浅层肌束血运良好而深层肌肉坏死,加之电性水肿明显。因而在健康组织与坏死组织的判断上十分困难。以1%亚甲蓝霜剂涂布于电烧伤创面后,由健康组
Electrical contact burn is caused by the direct contact with the power of the human body tissue coagulation necrosis, its area is small but deep, early removal of necrotic tissue will reduce the chance of infection, as the electrical contact with early tissue necrosis of the burn range is not easy to identify, although the skin surface damage Small, but deep in necrotic tissue. At the same time the scope of muscle necrosis and the interface is very irregular, the same muscular shallow muscle bundle blood supply good and deep muscle necrosis, coupled with electrical edema significantly. Therefore, it is very difficult to judge the healthy tissue and the necrotic tissue. After applying 1% methylene blue cream to the electric burn wounds, the healthy group
