问题 单项选择题 A1/A2型题

关于张力性气胸的叙述不正确的是()

A.最严重的气胸类型

B.胸腔内压进行性增高

C.有纵隔扑动

D.有皮下气肿

E.急救须立即在锁骨中线第2肋间用粗针穿刺减压

答案

参考答案:C

解析:张力性气胸病情危急。多见于严重的闭合性胸部损伤,空气来自破裂的支气管或较深、较大的肺裂伤,裂口与胸膜腔相通,呈活瓣状,吸气时活瓣开放空气能进入,呼气时活瓣关闭空气不能排出,胸膜腔内压力进行性升高,很快超过大气压,故又称高压性气胸。病人因伤侧肺被完全压缩,纵隔明显向健侧移位,健侧肺有不同程度的萎缩,腔静脉回流受阻,可迅速出现严重的呼吸循环障碍;此时,胸膜腔顶部常因高压挤破,气体沿纵隔上升至颈部,形成广泛的皮下气肿。临床出现极度呼吸困难、发绀、烦躁不安、昏迷。气管偏向健侧,伤侧胸部饱满、高度鼓音、呼吸音消失。急救须立即在锁骨中线第2肋间用粗针穿刺减压,针管由血管钳固定,针柄缚一乳胶指套,上剪开1cm,起活瓣作用,任呼吸时胸膜腔内积气排出、待病情稍稳定,再转院行患侧胸膜腔闭式引流或剖胸探查术。

Autumn and winter are cold and flu seasons. Will the old advice about dressing warmly help prevent a cold, or if you get sick, should you follow the old saying, “feed a cold and starve a fever?” And what about that fever? Should you take medicine to reduce your temperature, or is it better to let the body treat the fever itself? Everyone seems to have an answer. But is popular wisdom valuable?

Doctor Nelson knows a lot about cold and flu seasons. Nelson says research may be just starting to provide proofs for long-held beliefs. For example, scientists for years were against the idea that getting cold and wet might cause colds or flu. But recent studies have shown that cold temperatures cause stress on the body, and that stress can create conditions more inviting to viruses. So maybe it does make sense to wrap up warmly before going outside.

And what about feeding a cold and starving a fever? Nelson says if you have a cold and are hungry, you should eat. But a fever, especially a high one, suggests a more serious problem. He says people are usually not hungry when they have a high fever. Eating might even make a person sick. But drinking enough water is important. A fever easily makes the body lose water.

Finally, when should you treat a fever? Nelson says a fever should be treated if it stays at

40℃ or above for a day or more. A high temperature can damage brain cells. The doctor also believes in treating a fever if it prevents a person from sleeping.

Medicine like aspirin, for example, can be used to reduce pain and fever. But aspirin should not be given to children because it can cause serious problems.
