英语翻译
It is difficult for doctors to help a person with a hurt brain.Without enough blood,the brain lives only three to five minutes.Sometimes the hurt brain gets better by itself.More often the doctors cannot fix the hurt brain.Sometimes they are afraid to try something to help.It is dangerous to work on the brain.The doctor might make the person worse if he works on the brain.
Doctor Robert White,a famous professor and doctor,thinks he knows a way to help.He thinks doctors should try to make the brain become very cold.If it is very cold,the brain can live without blood for 30 minutes.This gives the doctors a longer time to do something for the brain
Doctor Whites idea works well on monkeys.Are there other problems with human beings?Doctor White thinks doctors will use his idea on human beings.He thinks it will help people who have to die when their heart stops; doctors can start it again.The problem comes when the brain is without blood for three to five minutes; the person has a living body,but a dead brain.Maybe in the future,doctors will try Doctor Whites idea.When the persons heart stops,the doctors will quickly try to cool the blood.They will have 30 minutes to start the heart again.Maybe there will be no problem with the brain.
