问题 问答题 简答题

试述经口气管内插管术的操作程序。

答案

参考答案:

(1)洗手、戴口罩、推抢救车至急救患者身旁;

(2)插管前应先给病人吸氧:有呼吸——高浓度氧,无呼吸——球囊一面罩辅助呼吸;

(3)插管时喉镜应向上、向后、向右用力,有助于暴露声门通过伸曲颈部和抬高头部,寻找暴露声门的最佳位置,一般口、咽、喉在一条轴线上为佳;

(4)右手强迫病人张口,左手紧握喉镜柄,镜片经病人右口角置人,并同时将舌体推向左侧,以免舌体充斥镜片右侧视野;

(5)右手推病人前额,使头部适度后仰,将镜片移向中线,并轻轻向前推进,暴露悬雍垂、咽腔和会厌;

(6)见声门,应迅速将气管导管置入,使套囊刚好位于声门之下;

(7)放置牙垫,取出喉镜。

(8)通过听诊上腹部、腋中线、腋前线、胸骨左右侧确定导管的位置。

(9)气囊充气恰好封闭气道,通常为3~5ml,通气时听声门是否有气流,以确定封闭效果;

(10)确定导管进入气管内后,用胶布固定导管和牙垫,连接呼吸机或人工气囊施行呼吸支持。

These days it is found that school students hardly have any sports. Is it because they have no       in sports? It may not be true. They often say they have        more important things to do.

What are these important things? Exams! They have to    __   themselves ready for all kinds of exams and tests in school. So many of them almost become  bookworms(书呆子). In the past in the summer holidays, they could do       they liked, but now they have to spend all their time preparing for exams. So       have kept them away from going in for sports.

Because of the pressure from        parents and teachers, they have to work harder and spend most of their time     __   books. As for the students themselves, they don’t want to       the lessons because they want to further their studies. So it is necessary to give all of their spare time to their studies and       up their school sports.  

It’s true a good education cannot go without physical training, the same is true, a quick mind hardly goes along with a        body. Without a strong body, you can never do anything well, how can you make great success in life?
