自体外循环进入临床应用以来,从事这方面的研究者已有认为,脉动性的心肺旁路最终要取代非生理性的无脉动血流。然而,它的实际意义并不是那么容易为人们所理解。由于简便,高效率的无脉动滚动泵迅速成功地应用于临床,并有Wesolowsk等的著作指出脉动性和非脉动性灌注无重要差别,因此有关这个问题的讨论沉默了,脉动性灌 Since the introduction of extracorporeal circulation into clinical practice, researchers in this area have come to believe that pulsatile cardiopulmonary bypass will eventually replace non-physiological, pulsatile blood flow. However, its practical significance is not so easy for people to understand. Because of the simplicity and efficiency of pulseless roller pumps, which have been rapidly and successfully used clinically, and Wesolowsk et al. Have pointed out that there is no significant difference between pulsatile and non-pulsatile perfusion, the discussion of this issue is silent, and pulsatile irrigation
