自从19世纪60年代提出了输入大量冷藏库血导致降温和心律失常问题以来,市售的温血器应运而生。现用的温血器可适当加温血液,但有损于最适流率。失血性休克时应用PRBCs代替全血以增加携氧能力而使最适流率问题更复杂化了。多年来已认识到,由于PRBCs的高粘度和微凝聚导致输入时间过长,增加了获得最适流率的困难。我们的设计欲确定,PRBCs容器内加入45℃生理盐水是否比习用的温血
Since the 1960s the introduction of a large number of refrigerated blood supply led to the problem of cooling and arrhythmia, the commercial warm-blooded came into being. Current warm blood can be appropriate to warm up the blood, but detrimental to the optimal flow rate. The application of PRBCs in place of whole blood to increase oxygen carrying capacity in hemorrhagic shock complicates the optimal flow rate problem. Over the years it has been recognized that due to the high viscosity and microaggregation of the PRBCs, the input time is too long, increasing the difficulty of obtaining the optimum flow rate. We designed to determine whether PRBCs containers with 45 ℃ saline than the conventional warm blood
