Experiments in dogs showed that the high levels of cellular aggregation and trauma caused by cariodtomy suction can be considerably reduced by the avoidance of air aspiration. A hypothesis is proposed to explain this on the basis of shear stresses in the inlet cannula. Roller pump suction was also found to be slightly more traumatic than vaccum suction, but contact of the blood with the pericardium had no effect so long as the pericardium and epicardium had been previously washed with saline.
对狗的实验表明,通过避免空气吸入,龋切吸引术所造成的高水平细胞聚集和创伤可大幅减少。基于入口套管中的剪应力,提出了一种假设来对此进行解释。还发现滚压泵吸引术比真空吸引术造成的创伤略大,但只要心包和心外膜事先用盐水冲洗过,血液与心包接触就没有影响。
