医者临床诊病，时有病者或其家属亲友提出“请将死马当活马医”既闻此语，医者心中当然十分清楚且凄然，这又是一位危重笃急、久治难愈的终末期病人。生命已近绝望，还需最后努力一搏，又并不指望出现奇迹，聊尽人事而已，即此意也。“死马当活马医”是俗语，据说自唐代以来便有， The healers are clinically diagnosed. When the patient or relatives of his family propose, “please bring the dead horse as a living horse doctor”, both of these words are heard. The heart of the doctor is of course very clear and sad. It is also a critical and long-term cure. More end-stage patients. Life is almost desperate, and it takes a last-ditch effort. It does not expect a miracle. It is a matter of personal interest. “The dead horse is a living horse doctor” is a common saying and it is said that it has been since the Tang Dynasty.
