<p>Anaphylaxis: First aid 过敏症</p>
<p> A severe allergic reaction (anaphylaxis) can produce shock and life-threatening respiratory distress. In sensitive people, anaphylaxis can occur within minutes or up to several hours after exposure to a specific allergy-causing substance. Almost any allergy-causing substance — including insect venom, pollen, latex, certain foods and drugs — can cause anaphylaxis. Some people have anaphylactic reactions from unknown causes. </p>
<p>严重的过敏反应(过敏症)能招致休克和威胁生命的呼吸困难。一些敏感性体质的人群,在暴露于特定的引起过敏的物质时,会在几分钟至几小时之内发生过敏反应。几乎所有的致敏物质——包括昆虫毒液、花粉、橡胶、某些食物和药品——都能引发过敏症。一些人也会因为不知名的原因引发过敏反应。</p>
<p> If you're extremely sensitive, you might break out in hives, and your eyes or lips might swell severely. The inside of your throat might swell as well, even to the point of causing difficulty breathing and shock. Dizziness, mental confusion, abdominal cramping, nausea, vomiting or diarrhea also may accompany anaphylaxis.</p>
<p> 如果你非常容易过敏,你也许会发麻疹,你的眼睛或嘴唇也许会很肿胀。你的喉咙也会肿,甚至致使呼吸困难和休克。过敏症还可以伴随有头昏眼花,精神错乱,腹部绞痛,恶心反胃,上吐下泄等症状。</p>
<p> If you've had an anaphylactic reaction in the past, carry medications with you as an antidote. Epinephrine is the most commonly used drug for severe allergic reactions. It comes only as an injection that must be prescribed by your doctor. You should also carry an antihistamine pill, such as diphenhydramine (Benadryl, others), because the effects of epinephrine are only temporary. Seek emergency medical attention immediately after taking these medications. </p>
<p>如果你过去有过敏症病史,应随身携带药品。肾上腺素是最常见的抗过敏药。它是只能注射输入,且须由医生开处方。你也应该携带抗阻胺剂药片,如苯海拉明(本那君等),因为肾上腺素只是起一个临时作用。服下这些药物后,应立即寻求医疗急救。</p>
<p> If you observe someone having an allergic reaction with signs of anaphylaxis:</p>
<p> 1. Call 911 or your local medical emergency number. </p>
<p>2. Check for special medications that the person might be carrying to treat an allergic attack, such as an auto-injector of epinephrine (for example, EpiPen). Administer the drug as directed — usually by pressing the auto-injector against the person's thigh and holding it in place for several seconds. Massage the injection site for 10 seconds to enhance absorption. If your doctor prescribed an auto-injector of epinephrine, read the instructions before a problem develops and also have your household members read them. After administering epinephrine, have the person take an antihistamine pill if he or she is able to do so without choking. </p>
<p>3. Have the person lie still on his or her back with feet higher than the head. </p>
<p>4. Loosen tight clothing and cover the person with a blanket. Don't give anything to drink. </p>
<p>5. If there's vomiting or bleeding from the mouth, turn the person on his or her side to prevent choking.</p>
<p> 6. If there are no signs of circulation (breathing, coughing or movement), begin CPR. </p>
<p>如果你发现某人有下列过敏症症状:</p>
<p>1、 拨打当地医疗急救电话。 </p>
<p>2、 检查病人是否随身携带了抗过敏症药品,如一支肾上腺素自动注射器(如EpiPen)。直接注射药品——通常在病人的大腿处注射,并保持几秒钟。按摩注射处10秒,促进吸收。如果你的医生为你开了肾上腺素自动注射器的处方,请在过敏症发作之前阅读说明,并让你的家人阅读说明。在注射肾上腺素之后,在病人能吞咽而不会窒息的情况下,让病人服用抗阻胺剂药片。</p>
<p>3、 让病人背朝下平躺,使其脚比头高。</p>
<p> 4、 松开病人的紧身衣物,盖上毯子。不要喂病人任何喝的。 </p>
<p>5、 如果有呕吐物或血从病人嘴人流出,将病人翻至侧躺,以避免其窒息。 </p>
<p>6、 如果病人没有身体循环的象征(如呼吸、咳嗽或移动),则开始进行心肺复苏术。</p> |
