问题 单项选择题 A1/A2型题

关于颅内肿瘤切除术后创腔引流,下列说法正确的是()

A.创腔引流的目的是防止形成脑脊液漏

B.术后创腔引流袋放置于头旁枕上或枕边,高度应高于头部创腔水平面

C.术后48小时后,可将引流袋略抬高,以期较快引流出创腔内的液体

D.引流3~4日后,当血性脑脊液转清,即可拔除引流管

E.引流5~6日后,当没有脑脊液流出,即可拔除引流管

答案

参考答案:D

解析:因为创腔引流的目的是引流血性渗液和气体,使残腔逐步闭合,故A不对。术后创腔引流袋放置于头旁枕上或枕边,高度应与头部创腔水平面保持一致,以保证创腔内一定的液体压力,以避免脑组织移位;高于创腔平面难以达到引流的目的,故B不对。术后48小时后,可将引流袋略放低,以期较快引流出创腔内的液体,故C不对。引流3~4日后,当血性脑脊液转清,即可拔除引流管,以免形成脑脊液漏,故E不对,D正确。

“If you want to see a thing well, reach out and touch it!”That may seem a strange thing to say. But touching things can help you to see them better. Your eyes can tell you that a glass ball is round. But by holding it in your hands, you can feel how smooth* and cool the ball is. You can feel how heavy the glass is. When you feel all these about the ball, you really see it. With your skin, you can feel better. For example, your fingers can tell the difference between two coins*  in your pocket. You can feel a little drop of water on the back of your hand, too.

All children soon learn what “Don’t touch!” means. They hear it often. Yet most of us keep on touching things as we grow up. In shops, we touch things as we might buy: food, clothes. To see something well, we have to touch it.

There are ways of learning to see well by feeling. One way is to close your eyes and try to feel everything that touching your skin. Feel the shoes on your feet, the clothes on your body, the air on your skin. At first, it is not easy to feel these things. You are too used to them!

Most museums are just for looking. But today some museums have some things to touch. Their signs say, “Do touch!” There you can feel everything on show. If we want to see better, reach out and touch. Then you will really see!
