Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Differences in phagocytic capacity of neutrophils in blood is measured by way of direct microscopic visualisation of ingestion of Zymosan particles and by flow cytometric analysis using staph. aureus PHrodo bioparticles at baseline, during and after CPB. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Differences in neutrophil priming status is measured by differences in cell surface expression markers (CD11b and CD62L) and release of reactive oxygen species by flow cytometric analysis at baseline, during and after CPB 2. Differences in the serum cytokines of blood is measured using an ELISA assay at baseline, during and after CPB | — |
