FIRST AID FOR BURNS

CAUSES OF BURNS
You can get burnt by a variety of things: hot liquids, steam, fire, radiation⑩， the sun, electricity，acids ， or other chemicals ．
TYPES OF BURNS
Burns are divided into three types，depending on the depth of skin damage[6]．
［6］动词(-ing)形式短语作方式状语。
·First-degree burns These affect only the top few millimetres of the skin．These burns are not serious．Examples include mild sunburn and burns caused by other minor household incidents [7]．
［7］过去分词短语作后置定语，修饰burns。
·Second-degree burns These go below the top layer of the skin．They are serious and take a few weeks to get better．Examples include burns caused by hot liquids．
·Third-degree burns These affect every layer of the skin, and sometimes the tissue under it．Examples include burns caused by electric shocks ，burning[8] clothes，or petrol fires．These burns cause very severe internal injuries and the victim must go to the hospital at once．
［8］动词(-ing)形式作定语，修饰clothes。
CHARACTERISTICS OF BURNS
First-degree burns
·dry, red, and mildly swollen
·mildly painful

2　Dry the burnt area gently with a clean cloth．
3　Remove any clothes using scissors[9] if necessary[10], unless you see the fabric sticking to the burnt skin[11]．
[9]动词-ing形式短语作方式状语。

[12]过去分词injured作定语，修饰areas。
[13]as引导原因状语从句。
5　If burns are on the face, make sure the victim can still breathe ．
6　If the victim is suffering from second or third-degree burns, there is an urgent need to take him/her to the hospital at once．
烧伤急救
皮肤是人体的重要组成部分，也是人体最大的器官。皮肤是抵御疾病、毒素和太阳光线的屏障。它还有助于控制体温，防止身体流失过多水分，在外物过热或过冷时发出警告，并让你有触觉。可想而知，皮肤烧伤会导致非常严重的伤害。在处理烧伤时，第一步也是最重要的一步就是进行急救。
烧伤的原因
你可能会被各种各样的东西烧伤：灼热的液体、水蒸气、火、辐射、太阳光、电、酸或其他化学物质。
烧伤的类型
根据皮肤损伤的深度，烧伤或烫伤可分为三种类型。
·一度烧伤：这类烧伤只伤及皮肤表层几毫米。这类烧伤并不严重。例如轻微的晒伤和其他轻微的家庭事故造成的灼伤。
·二度烧伤：这类烧伤伤及皮肤表层以下。它们是严重的，需要几个星期才能好起来。例如由灼热的液体引起的烫伤。
·三度烧伤：这类烧伤会伤及每一层皮肤，有时还会伤及皮下组织。例如由电击、衣服燃烧或汽油着火引起的烧伤。这类烧伤会造成非常严重的内伤，伤者必须马上去医院。
烧伤的特点
一度烧伤：
·干燥、发红、微肿
·微痛
·按压时变白
二度烧伤：
·又红又肿；起水疱；表层渗液
·极其疼痛
三度烧伤
·(皮肤)发黑或变白
·肿胀；常常可见皮下组织
·如果神经受损，则轻微疼痛或完全无痛感；烧伤处周围或有痛感
急救处理
1　将烧伤部位放在流动的凉水下冲洗，特别是在烧伤后的前十分钟内。凉水可以阻止烧伤进程，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　如有必要，用剪刀剪掉衣服，除非你看到布料已粘在烧伤的皮肤上了。
4　用一块干净透气的布覆盖住烧伤部位。在受伤部位涂油是不可取的，因为这会阻碍伤口散热，并可能导致感染。
5　如果是脸部烧伤，确保伤者还能呼吸。
6　如果伤者是二度或三度烧伤，需立即送他/她去医院。
