title: [Combined methods for economic blood utilization in cardiac reoperations in children].
abstract: During 47 re-operations on the open heart the authors used the method of autotransfusion, predeposition of the patient's blood and intravenous administration of aprotinin to reduce postoperative haemorrhage and blood consumption. The patients were classified according to the methods or their combinations used into three groups and the authors compared, using statistical methods the blood losses, blood consumption, haemolysis, renal function and the effect of the methods used on the morbidity. The results were compared with a control group where the mentioned methods of economizing on blood were not used. The authors recorded significantly higher haematocrit values in all three groups where economic methods were used at the end of the extracorporeal circulation (EC), as compared with the control group. The volume of the administered blood transfusion was significantly lower in group 1 where an autotransfusion apparatus Cell saver was used. The volume of the administered blood transfusion in the other groups did not differ when evaluated by statistical methods. The filling of the apparatus for extracorporeal circulation was blood free in 90% in group 1, in 75% in group 2, in 92.2% in group 3 and in 75% in the control group. Blood losses via thoracic drains did not differ significantly in different groups though there was a wide range of recorded values. In both groups 2 and 3 where patients were given aprotinin haemoglobinuria was more frequent, as confirmed by laboratory tests. The authors observed also a greater diuresis, without laboratory evidence of impairment of renal function.(ABSTRACT TRUNCATED AT 250 WORDS)
