The contact of blood with the artificial extracorporeal circuit causes a systemic inflammatory response due to blood activation. In this study, we compared two different paediatric membrane oxygenators used for extracorporeal circulation: a hollow fibre membrane oxygenator (Dideco Masterflo D-701, n=10), and a flat sheet silicone membrane oxygenator (Avecor Kolobow 800-2A, n=10). Blood compatibility was indicated by measuring complement activation as well as leukocyte and platelet activation. In patients perfused with a flat sheet membrane oxygenator, concentrations of complement split products C3a were significantly increased 30 minutes after the start of bypass (p<0.01), whereas only a mild increase of C3a was found in patients perfused with a hollow fibre membrane oxygenator. Leukocyte and platelet counts dropped uniformly in both groups after the start of bypass mainly due to hemodilution. Activation of leukocytes and platelets identified by both plasma β-glucuronidase and β-thromboglobulin was similar in both groups. Infants perfused with a flat sheet membrane oxygenator received significantly more donor blood than those perfused with a hollow fibre oxygenator (p<0.05). These results indicate that when used during paediatric cardiopulmonary bypass, a flat sheet membrane oxygenator has a higher complement activity than a hollow fibre membrane oxygenator, which is probably due to the relatively larger blood-surface contacting area of the oxygenator.

O2 Supply

Whole-body hypoxia may increase peripheral O2 demand because it increases catecholamine calorigenesis, an effect attributable to beta 2-adrenoceptors. We tested these possibilities by pump-perfusing innervated hindlimbs in eight dogs with autologous blood kept normoxic by a membrane oxygenator while ventilating the animals for 40 min with 9% O2 in N2 (NOB group). Similar periods of normoxic ventilation preceded and followed the hypoxic period. A second group (n = 8, beta B) was pretreated with the specific beta 2 blocker ICI 118,551. Hindlimb O2 uptake was elevated by 25 min of hypoxia in NOB, whereas whole-body O2 uptake was reduced. Limb O2 uptake remained elevated in recovery, but all effects on limb O2 uptake were absent in beta B. Hindlimb resistance and perfusion pressure increased in hypoxia in both groups, and there was little evidence of local escape from reflex vasoconstriction. These results clearly indicated that global hypoxia increased O2 demand in muscle when the local O2 supply was not limited and that beta 2-receptors were necessary for this response. Autoregulatory escape of limb muscle blood flow from centrally mediated vasoconstriction during whole-body hypoxia was also shown to be practically nil, if normoxia was maintained in the limb.
