氢氟酸(HF)为腐蚀性最强的一种无机酸,由于此酸的可溶性及化学活性,HF灼伤较其它化学灼伤为严重。其灼伤过程可分为二个阶段;包括快速产生皮肤脱水,引起凝固性坏死,继以续发阶段,HF的膜渗透性系数与水相似,为F的7倍,HF穿入皮下组织,离解为F~-离子,与组织钙起反应。未经治疗的灼伤,初起时,仅及皮肤表面组织,发展至深部组织,甚至引起骨破坏。临床症状主要为(局)部剧烈疼痛及进行性组织破坏,因此有效疗法,需中和被吸收的F~-离子,来阻止延续性组织破坏。局部治疗方案:使接触部位皮肤的HF及皮肤内吸收的F离子失活,葡萄糖酸钙局封,经常作为
Hydrofluoric acid (HF) is the most corrosive inorganic acid. Due to its solubility and chemical activity, HF burns are more severe than other chemical burns. The burn process can be divided into two stages; including rapid skin dehydration, causing coagulation necrosis, followed by continued phase, HF membrane permeability coefficient similar to water, 7 times F, HF penetrate the subcutaneous tissue, dissociation For F ~ - ions, with tissue calcium reaction. Untreated burns, the first time, only the skin surface tissue, the development of deep tissue, and even lead to bone destruction. The main clinical symptoms (Department) Department of severe pain and progressive tissue damage, so effective therapy, the need to neutralize the absorbed F ~ - ions to prevent the destruction of the continuity of the organization. Local treatment programs: the contact area of the skin HF and skin absorption of F ion inactivation, calcium gluconate, often as
