eq \a\vs4\al([译文参考])
烧伤急救处理
皮肤是人体必不可少的一部分，也是人体最大的器官。皮肤是一道屏障，能阻挡疾病、毒素和太阳光线的侵入。皮肤还有助于控制体温，防止身体流失过多的水分，在外物过热或过冷时发出警告，并使你拥有触觉。可想而知，烧伤会造成严重后果。在处理烧伤时，第一步也是最重要的一步就是采取急救措施。
烧伤的原因
很多东西都会造成烧伤：灼热的液体、蒸汽、明火、辐射、太阳光、电流、酸性物质或其他化学品。
烧伤的种类
根据皮肤损伤的深度，烧伤分为三类。
·一度烧伤：仅伤及最上层几毫米的皮肤。此类烧伤并不严重，如轻度的晒伤和其他轻微家庭事故造成的烧伤。
·二度烧伤：伤及最上层皮肤以下的部位。此类烧伤较为严重，需要数周时间才能康复，如灼热的液体造成的烧伤。
·三度烧伤：伤及每一层皮肤，有时甚至伤及皮下组织，如因电击灼伤、衣服着火造成的烧伤，或汽油起火造成的烧伤。此类烧伤会引起非常严重的内部损伤，伤者必须立即送往医院。
烧伤的特点
一度烧伤
·干燥、发红、微肿
·微痛
·受压时变白
二度烧伤
·发红、肿胀；起水疱；表层渗液
·极度疼痛
三度烧伤
·皮肤发黑或变白
·肿胀；通常可见皮下组织
·如果神经受损，则微痛或无痛感；创面边缘或有痛感
急救处理
1．将烧伤部位放在流动的冷水下冲洗，尤其在前十分钟。冷水冲洗可阻止烧伤进程，缓解疼痛和肿胀。
2．用干净的布轻轻吸干烧伤部位的水分。
3．如果有必要，用剪刀剪掉烧伤部位的衣服，除非你看到衣服与被烧伤的皮肤粘连在一起。
4．用干净透气的布盖住烧伤部位。在受伤处涂抹油膏不可取，因为这会阻碍伤口散热，而且可能引发感染。
5．如果烧伤部位在脸上，应确保伤者仍可呼吸。
6．如果伤者是二度或三度烧伤，必须立刻送往医院。
