The relationship between @entity1760 , XXXX and @entity1063 blood concentrations during CABG with normovolemic hemodilution.

The effects of procedures with extracorporeal circulation on the disturbance of relationships between blood @entity1760 ( @entity4612 ), @entity1425 , and @entity1063 levels have not been explicitly explained. It is assumed that both @entity1272 and increased concentration of the above mentioned hormones exert adverse effects on the myocardium often causing life threatening disorders. This problem is particularly important in cases of @entity1562 , observed after extracorporeal circulation procedures. The complex nature of the procedures and the intraoperative normovolemic hemodilution (NH) employed are likely to alter @entity4612 , @entity1425 , and @entity1063 concentrations, as well as the above mentioned relations. The aim of the study was to evaluate the changes in blood @entity4612 , @entity1425 and @entity1063 concentrations in @entity1 undergoing extracorporeal circulation and normovolemic hemodilution. The study encompassed 16 @entity1 operated on for stable @entity301 (I or II degrees according to the Canadian Scale). The @entity1 were divided into two groups according to body weight: A) @entity1 weighing less than 75 kg and B) @entity1 weighing more than 75 kg. The degree of NH caused by constant volume of priming (1800 mL) was determined on the basis of hematocrit measurements and in relation to body weight. The examinations were conducted in 5 stages: 1) after radial artery cannulation before anaesthesia and surgery, 2) during hemodilution and deepest @entity2332 , 3) after surgery before sending the @entity1 to Intensive Postoperative care Unit, 4) in the first postoperative day, 5) in the second postoperative day. The observations showed an increase in @entity1425 levels in group A in the second stage and of @entity1063 levels in stage 4. Decreased blood @entity4612 levels were noted in all the @entity1 in the second stage, however in group A significantly lower values were also observed in stage 3. Moreover, the correlation between @entity4612 level changes and blood @entity1425 and @entity1063 levels were observed. The study revealed significant effects of extracorporeal circulation procedures on adrenergic reactions as well as blood @entity1760 concentrations. It seems that the degree of NH is the main factor determining blood levels of @entity4612 , @entity1425 and @entity1063 during the use of a @entity299 , which may be particularly relevant in @entity1 with @entity299 and low body weight.
