问题 单项选择题 A1/A2型题

心包炎发生压塞综合征时最快解除压塞的措施是()

A.大剂量使用激素

B.大剂量使用抗生素

C.大剂量使用利尿药

D.心包穿刺

E.应用血管扩张药

答案

参考答案:D

解析:心包穿刺可直接将心包积液抽出,即刻可减轻心包腔内的压力,解除压塞,使心脏能接受到足够的血容量,迅速解除心脏压塞。静脉滴注激素对在应用有效抗生素的前提下,可加快积液的吸收;对细菌性的心包炎积液,应用抗生素是必要的;对因心力衰竭所致的心包积液,应用利尿药或血管扩张药有助于加快积液量的减少。但上述几种方法均不能快速解除心脏压塞征。

      Science fiction and fantasy are interrelated,and it can be hard to tell the difference between

the two.The two terminologies (术语)have been widely discussed,and it is very difficult to draw

a line between the two.In the words of great writer,Issac Asimov,science fiction is based on

technology and science and is possible.Science fiction can be about robots and space and has

its bases in science.On the contrary,fantasy is only imaginary,and involves things that do not

exist in real life.Fantasy can be about talking animals or something immortal.Science fiction

shows things that could possibly take place in the real world.Fantasy adds realism to things

that are unlikely to happen.

fiction,social science fiction,time travel,military science fiction,super human fiction and space

Fiction.
