输注血浆有些什么不良反应?

答案

参考答案:

输注血浆的不良反应如下:

(1)传播病毒的危险:对供血者化验检测项目有一定局限性,即使已检测的项目亦不能完全排除假阴性。(

2)同种抗原抗体反应:血浆中混入少量血细胞抗原和血浆蛋白中各种抗原表型,都能激发受血者产生同种抗体,进而发生各种免疫反应。

(3)过敏反应:特别是荨麻疹和发热反应比较多见。

(4)给血容量正常的人输注血浆,可使循环超负荷,重者引起肺水肿。给血浆蛋白浓度正常的人输注血浆,可破坏体液胶体渗透压平衡。血浆中含有抗凝剂,输注过多可使肝功能异常病人出现低钙。

     Michael a typical American, stays home on workdays. He plugs into his personal

computer terminal in order to connect with the office. After work he puts on his

headphones, watches a movie on his home video recorder or plays baseball on the

computer. On many days, michael doesn't talk to any other human beings, and he

doesn't see any people except the ones on television. Michael is imaginary, but his

lifestyle is very possible. The inventions of modern technology seem to be cutting

US off from contact with our fellow human being

     The world of business is one area which technology is isolating. US experts say,

for example, that many people will soon be able to work at home. With access(接通)

to a large central computer, employees such as office clerks, insurance agents and

accountants could do their jobs at display terminals in their own homes. They would

never have to actually see the people they're dealing with. In addition, the way

employees are paid will change. Workers' salaries will be automatically paid into

their bankaccounts (账户 ) , makingpaper checks unnecessary. No workers will

stand in line to receive their pay or cash their checks. Personal banking will change,

too. Customers will deal with machines to put in or take out money from their accounts.

     Another area that technology is changing is entertainment. Music,for instance,was

once a group experience. People listened to music at concert halls or in small social

gatherings. For many people now however, music is an individual experience. Walking

along the street or sitting in their living rooms, they wear headphones to build a wall

of music around them. Movie entertainment is changing, too. Movies used to be social

events. Now, fewer people are going out to see a movie. Many more are choosing to

wait for a film to appear on television or are borrowing videotapes to watch at home.

Instead of laughing with others, viewers watch movies in their own living rooms.
