当病人接受手术时,身边的机器不停地把人造血液注入手术患者的体内。或许你听起来难以置信,不过目前医学界正在尝试配制人造血,这给日趋紧张的医疗用血问题带来了曙光。我们的血液血液是生命的河流。血液包括血浆和血细胞两部分。正常人的血是体重的1/13。一个体重60千克的人,约有4 500毫升血液。当伤病员失血达30%(1 300毫升)以上,如不采取输血抢救措施,就可能有生命危险。一次心脏外科手术,体外循环就需要几千毫升血液。
When the patient underwent surgery, the machine around him kept injecting artificial blood into the body of the operating patient. Perhaps you may sound unbelievable, but the medical community is currently trying to formulate artificial blood, which brings dawn to the increasingly tense medical blood problem. Our Blood Blood is the river of life. Blood includes plasma and blood cells in two parts. Normal blood is 1/13 of body weight. A man weighing 60 kg has about 4,500 ml of blood. When the wounded and sick person has a blood loss of up to 30% (1,300 ml), if there is no blood transfusion rescue, it may be life-threatening. A cardiac surgery, cardiopulmonary bypass will need thousands of milliliters of blood.
