Fever

如果她的温度为100.4度或更高，您的孩子发烧。

身体有几种维持正常体温的方法。人体对温度的变化反应：

• 增加或减少年代weat production
• 将血液从皮肤的表面移开或靠近
• getting rid of, or holding on to, water in the body
• 自然想寻求更凉或温暖的环境

What causes a fever?

When your child has a fever, her body works the same way to control the temperature but it resets its thermostat at a higher temperature. The temperature increases for a number of reasons:

• Chemicals called cytokines or mediators are produced in the body in response to an invasion from a microorganism, malignancy, or other intruder.
• 人体正在制造更多的巨噬细胞，即当入侵者存在于体内时，它们会进行战斗。这些细胞实际上“吞噬”了入侵的生物。
• 人体忙于产生与感染作斗争的天然抗体。这些抗体将识别下一次试图入侵的感染。
• Many bacteria are enclosed in an overcoat-like membrane. When this membrane is disrupted or broken, the contents that escape can be toxic to the body and stimulate the brain to raise the temperature.

What conditions can cause a fever?

以下条件会引起发烧：

• infectious diseases
• certain medications
• heat stroke
• 输血
• disorders of the brain

What are the benefits of a fever?

A fever actually helps the body destroy its microbial invader. It also stimulates an inflammatory response, which sends all kinds of substances to the area of infection to protect the area, prevent the spread of the invader, and start the healing process.

我的孩子发烧的症状是什么？

随着温度升高，发烧的儿童可能会变得更加不舒服。以下是发烧的最常见症状。但是，每个孩子的症状可能不同。除了大于100.4度华氏度的体温外，症状还包括：

• Your child may not be as active or talkative as usual.
• She may seem fussier, less hungry, or thirstier.
• 您的孩子可能会感到温暖或热。请记住，即使您的孩子觉得自己正在“燃烧”，实际的直肠或口服温度也不那么高。

The symptoms of a fever may resemble other medical conditions. According to the American Academy of Pediatrics, if your child is younger that 2 months of age and has a rectal temperature of 100.4 degrees Fahrenheit or higher, you should call your pediatrician. If you are unsure, always consult your child’s physician for a diagnosis.

When should a fever be treated?

If your child is very uncomfortable, treatment may be necessary. Treating your child’s fever will not help her body get rid of the infection any quicker, but it will relieve discomfort associated with it.

Rarely, children between the ages of 6 months and 5 years can develop癫痫发作from high fever (called febrile seizures). If your child does have a febrile seizure, there is a chance that the seizure may occur again, but, usually, children outgrow the febrile seizures. A febrile seizure does not mean your child has epilepsy.

我该怎么做才能减少孩子的发烧？

Give her an anti-fever medication, such as acetaminophen or ibuprofen. DO NOT give your child aspirin, as it has been linked to a serious, potentially fatal disease, calledReye syndrome.

Other ways to reduce a fever:

• Dress your child lightly. Excess clothing will trap body heat and cause her temperature to rise.
• 鼓励您的孩子喝很多液体。
• Give your child a lukewarm bath.
• Place cold washcloths over areas of the body where the blood vessels are close to the surface of the skin such as the forehead, wrists, and groin.

When should I call my child’s physician?

根据美国儿科学会的说法，如果您的孩子的温度达到105华氏度，这被认为是医疗紧急情况，您的孩子需要立即医疗护理。

• Your child’s neck is stiff
• 皮肤上存在紫色斑点。
• Breathing is difficult AND does not improve after you clear the nose.
• 您的孩子无法吞咽任何东西，正在流口水唾液。
• Your child looks or acts very sick; if possible, check your child’s appearance one hour after your child has taken an appropriate dose of acetaminophen.

Call your child’s physician within 24 hours if your child, 3 months or older, has any of the following conditions present:

• 发烧是华氏或更高的华氏度（尤其是您2岁以上的孩子）
• 排尿会燃烧或疼痛
