甲亢伴严重支气管哮喘者禁用()

A.复方碘溶液

B.地西泮(安定)

C.普萘洛尔

D.甲状腺片

答案

参考答案:C

解析:

甲亢的药物治疗

复方碘溶液(A项)仅用于术前准备和甲状腺危象,它的作用为减少甲状腺充血,阻抑TH释放,抑制TH的合成和外周T4向T3的转换。甲状腺危象病人首选丙硫氧嘧啶(PTU),并在服用PTU后1~2小时再加用复方碘口服液,以抑制TH的释放。

普萘洛尔为β受体阻滞剂,能阻滞β受体,抑制T4向T3的转换,用以改善甲亢初治期的症状,疗效显著。但是若伴有严重的支气管喘或喘息型支气管炎,则要禁用。因为β受体阻滞剂能加重气管平滑肌的痉挛,增加小气道阻力。

There are differences between western culture and Chinese culture. We can see differences when we pay attention to the way words are used. Let’s look at the words about animals and plants. Most expressions in Chinese is about the dog, for example, “a homeless dog”, “a mad dog”, “a running dog” and “a dog catching a mouse”, have negative(消极) meanings. But in western countries, dogs are thought to be honest and good friends of humans. In English, people use the dog to describe positive(积极的) actions. For example, “you are a lucky dog” means you are a lucky person. And “every dog has its day” means each person has good luck sometimes. To describe a person’s serious illness, they say “sick as a dog”. The word “dog—tired” means very tired. However, Chinese love cats very much. But in western culture, “cat” is often used to describe a woman who is cruel(冷酷的). There are many other examples of how “cat” is used differently as well.
