手外伤清创时处理方法不正确的是

A.争取在6~8小时进行

B.骨折与脱位均尽可以当时予以复位固定

C.对未失活的皮肤尽量充分保留

D.不用止血带

E.注意保护重要的神经和血管

答案

参考答案:D

解析:早期彻底清创:清创越早,感染机会越少,疗效越好。一般应争取在伤后6~8小时进行。正确处理深部组织损伤,若能在清创的同肘修复深部组织,可获较好的疗效。污染严重,外伤超过12小时以上,或修复技术有困难者,可仅做清创和闭合创口,但有骨折和脱位者必须复位固定。至于肌腱和神经损伤,可留待二期修复。

This is (102) the mind of every animal I’ve ever met.
Research on animal intelligence also makes me wonder what experiments animals would (103) on humans if they had the chance. Every cat with an owner, (104) , is running a small-scale study in operant conditioning, we believe that (105) animals ran the labs, they would test us to (106) the limits of our patience, our faithfulness, our memory for terrain. They would try to decide what intelligence in humans is really (107) , not merely how much of it there is. (108) , they would hope to study a (109) question. Are humans actually aware of the world they live in (110) the results are inconclusive.
