Experimental Studies on Extracorporeal Circulation by Rygg-Kyvsgaard Heart-Lung Machine, Hartman`s Solution Prime,and Moderate Hypothermia: [Part I]
Hartmann`s 용액으로 충진한 혈희석 체외순환에 관한 실험적 연구: (1보: 심폐기 Rygg-Kyvsgaard 의 혈산화와 혈압 및 혈액상에 미치는 영향)
Abstract
Total body perfusion using Rygg-Kyvsgaard Heart-Lung-Machine, Mark IV, Polystan was attempted in the dogs by the hemodilution method with total prime of buffered Hartman's solution and under hypothermia. The first of all, the functions of Rygg--Kyvsgaard Heart-Lung-Machine and the effects of the hemodilution perfusion by buffered Hartman's solution was studied. At the same time the changes of blood pressure, oxygen consumption, and influence on the blood pictures were observed before, during, and in 1-3 days after perfusion. Hemodilution rates were the average 74. 22cc/Kg(the ranges of 67 to 81 cc/Kg) and perfusion flow rates were maintained in the mean 62. 6cc/Kg/min., Although it was possible to check up to 87 cc/ Kg/min. The total body perfusion continued for 60-80 minutes. Hypothermia was employed between
