为什么要麻醉前用药?

答案

参考答案:

麻醉前用药是为了减轻病人的精神紧张和完善麻醉效果,其主要目的是:

(1)消除病人紧张、焦虑及恐惧的心情,产生意识松懈、情绪稳定和遗忘,并提高皮质对局麻药的耐受阈。

(2)提高病人痛阈,缓解或消除痛刺激向中枢传导,使痛反应减弱和镇痛。

(3)抑制呼吸道腺体的分泌功能,减少唾液分泌,以防发生误吸。

(4)消除麻醉或手术引起的不良反射,特别是迷走神经反射,抑制因激动引起的交感神经兴奋,以维持呼吸、循环系统的稳定。

There is a problem each of us faces in following advice on emotional healing: apologizing is difficult. We are trapped in what we think of ourselves by holding onto our pride. We can be selfish and not willing to admit our most obvious mistakes. Pride eats away at us as we argue or ignore the mistake.

It's happened to me. I have had too much pride and selfishness to apologize to a loved one I hurt. When I did want to apologize, I couldn't bring myself to face the other person. This is the pride I'm talking about. Maybe apologies come difficult for men because they're expected to be dominant. It's like the joke that a man never asks for directions when lost. Ladies are more emotionally open than guys and are willing to express it. Still, both genders wonder how to correctly apologize.

In shifting the focus on apologizing away from you, what does not apologizing do to other people? They feel hurt that you are not willing to communicate your mistake. They lose trust in you as you hide behind your mistake avoiding reality. They become angry with you, wondering why you do not tell them the truth. They may begin to counter your lack of apologies by not apologizing themselves and from this the relationship goes downhill as the two of you get caught in a power struggle.

You need to communicate your mistakes. A mistake you made is like a scratch and by not apologizing you are making the scratch a deeper wound and rubbing salt into it. You need to stop hurting the other person and yourself by learning to apologize. There is real power in apologizing and emotional healing.
