能否用全合成代用品取代人体血液?这是个在药物发展过程中科学家们和临床医生多次提出的问题,今天我们仍有同感。这已成为一个难以回答的问题:人们曾多方试图去开发一种可接受的血液代用品,但大都没有成功。因此人血或其成分在常规输液疗法中仍是必需给予的重要物质。胶体血浆扩充剂的临床应用已很广泛,但都不能代替红血球输 Can we substitute whole synthetic substitutes for human blood? This is a question raised many times by scientists and clinicians during the course of drug development. We still have the same feeling today. This has become an unanswerable question: There have been many attempts to develop an acceptable blood substitute, but most have failed. Therefore, human blood or its components in the conventional infusion therapy is still an important substance must be given. Clinical application of colloidal plasma expanders has been very broad, but they can not replace the red blood cells lose
