碱性烧伤远较酸性烧伤严重,因碱性化学物质与细胞结构中的脂类发生皂化反应与组织的蛋白质形成可溶于水的碱性蛋白物,引起组织液化性坏死,剩余的碱可继续向深部及周围组织渗透、扩散。常见的碱性致伤物质有氢氧化钾(苛性钾)、氢氧化钠(火 Alkaline burns are far more severe than acid burns because of the saponification of lipids in alkaline chemicals and cellular structures with the protein of the tissue to form alkaline proteins that are soluble in water, causing tissue liquefaction necrosis and the remaining base can continue To the deep and the surrounding tissue infiltration, proliferation. Common alkaline injury substances are potassium hydroxide (caustic potash), sodium hydroxide (fire
