Hematocrit change in the patients underwent open heart surgery using priming solution without blood

Abstract

The hematocrit change during cardiopulmonary bypass and postoperative period were studied in 34 patients, 15 females and 19 males  ranging in age from 15-45 years mean 28 by using extracorporeal circulation (CPB) priming solution without blood. They were 10 patients of congenital  heart disease and 24 patients of acquired heart disease. In extracorporeal circuit, priming perfusate composed mainly of Ringer’s lactate solution approximately 1,500-2,000 ml. was reinfused in the form of pack red cells by centrifugation. The result, hematocrit change during CPB was 26-28%, after CPB 1 hour for 6 times and everyday for 7 days hematocrit was 29.67-35.50%. We concluded that hemodilution technique develop mild anemia during CPB but it was be saved for open heart surgery by requiring no blood replacement.
