问题 单项选择题

关于麻醉中发生喉痉挛的处理错误的是()

A.消除刺激,诸如停止气道吸引、拔出口咽通气道等

B.加深麻醉,纯氧吸入

C.对于轻到中度的喉痉挛,面罩持续正压通气可能"冲开"痉挛

D.小剂量琥珀胆碱松弛喉肌

E.为赢得抢救时间,直接行环甲膜穿刺通气

答案

参考答案:E

解析:喉痉挛根据其气道梗阻程度分为轻度喉痉挛:仅在吸气时出现喉鸣,去除局部刺激后会自行缓解;中度喉痉挛:吸气和呼气时都出现喉鸣,需用面罩加压吸氧治疗;重度喉痉挛:声门紧闭,气道完全阻塞,可用粗静脉穿刺针行环甲膜穿刺吸氧,或静注琥珀胆碱迅速解除痉挛,然后加压吸氧或立即行气管插管进行人工通气。因此,不分喉痉挛的轻重,就直接行环甲膜穿刺吸氧显然不妥。

阅读下面一篇短文,判断下列句子是否符合短文内容,符合的用“A”表示,不符合的用“B”表示。

Clean water is not only important for people to produce food, but necessary for our life. However, many people in Asia and Africa don't have enough clean water to use. The World Health Organization reports that almost 4,000 children die each day of dirty water or lack (缺乏) of water.

Farmers use 70-85% of the world fresh water to produce food. People usually don't pay much attention to how much water industry(工业) uses, but you may be surprised to know that industry uses 59% of the water in developed countries.

Home use takes up(占据) only 8% in the world. But as cities grow, more water will be used. The local government has to try to make people use less water.

In 60% of European cities, people are saving water by using less. They even keep waste wafer for other use.

In Australia, the government has encouraged people to collect rainwater and recycle water from showers for a second use.

The US Environmental Protection Agency has made a water saving program to encourage families and businesses to check their water use and save more water. Scientists and the UN are looking for good water management as the key to solving the problem. We can all work together to protect our fresh water in our daily life.

小题1: In developed countries, most water is used by industry.
