Abstract / Bemerkung
Objective:
Blood cell trauma in cardiac surgery is mainly attributed to the use of the heart
lung machine and the oxygenator. The optimization of oxygenator design and membrane
technology (e.g., chemical properties of surface mate
rial), aiming at reducing the blood cell
alterations, is an objective of current developments. Clinical evaluation of different
oxygenators concerning alterations of blood cells and markers of organ function provide an
appropriate level of complexity becau
se various patient characteristics and operative data are
involved. Our clinical research database enables us to study the impact of different
oxygenator types on blood cells and markers of organ function in the homogenous group of
elective coronary artery
bypass grafting (CABG) patients.
Materials and Methods:
Prospective data from 4847 patients who underwent isolated
CABG were collected, of which 282 had off
-
pump coronary artery bypass grafting (OPCAB).
The blood cell parameters white blood cell (WBC) cou
nts, platelet (PLT) counts, and red
blood cell counts and the marker of organ function lactate dehydrogenase (LDH) and
creatinine clearance (CC) were determined pre
-
and postoperatively. The changes of these
parameters were analyzed among the 13
-
oxygenator
type groups and compared with the
OPCAB group. To account for individual differences in blood volume, flow rate, and bypass
time, we introduced a formula to normalize blood alterations per transfer cycle across the
oxygenator.
Results:
We could observe si
gnificant different blood cell alterations between the various
oxygenator groups. The increase of WBC was positive correlated with LDH and negative
with CC. The oxygenators with the least decrease in PLT had the highest WBC increase. Two
manufacturer’s mod
ifications in oxygenator surface material ar
e observed to result in a trade
-
off between induced WBC and PLT blood alterations.
Conclusion:
Cardiotomy suction blood separation had a clear effect on blood activation
parameters. The cardiotomy suction blood s
eparation enabled us to separate a main part of
blood activation and prevent its negative effects. Further studies should prove whether
retransfusion of cardiotomy suction blood without cell saver is indicated at all in routine
CABG.
