急性胰腺炎患者镇痛不宜应用（）

A.异丙嗪

B.吗啡

C.哌替啶

D.阿托品

E.普鲁卡因

答案

参考答案：B

解析：吗啡可引起Oddi括约肌收缩，不宜应用。可用阿托品0.5～1mg或山莨菪碱5～10mg加异丙嗪25mg，每6～8小时一次，肌注；疼痛严重者可加用哌替啶50～100mg，肌注；普鲁卡因0.5～1．0g加入生理盐水500ml中静脉滴注，对减轻疼痛也有效果。

Dear David,
     I am very upset and I need some help. You know I will finish college soon, and I must decide
about my future. I am outgoing and good at speaking. I love to talk with others. So I want to be
a TV reporter.
     But everyone in my family has a different idea about my future. I don't know how to choose.
My father says I should go to England to study. My mother says I should be a doctor as she. And
my brother wants to start a computer company (公司) with me. My sister is a singer, so she asks
me to learn to sing from her. And my uncle works on a farm. He says I can work with him on his
farm.
     So, you know it is very difficult for me to decide which one is better.
     What do you think?
     Write to me soon. 
                                                                                                                                 Yours, 
                                                                                                                                Michael
