Abstract
Comparative coronary sinus flow rates and oxygen AV difference were studied in dogs undergoing left heart bypass with left atrial or left ventricular drainage at similar maximum obtainable flow rates. Left atrial bypass decreased the coronary sinus flow rates and oxygen consumption when compared with control values. These values were further decreased when left ventricular bypass was used. The oxygen consumption data were highly significant and give further evidence of increased effectiveness of complete bypass of the left ventricle in myocardial support systems.
摘要
在以相似的最大可获得流量进行左心房或左心室引流的左心旁路手术的犬类中，研究了冠状窦血流速率和氧动静脉差值。与对照值相比，左心房旁路降低了冠状窦血流速率和氧消耗。当使用左心室旁路时，这些值进一步降低。氧消耗数据具有高度显著性，进一步证明了在心肌支持系统中完全绕过左心室的有效性增加。
