1 Fat contamination of pericardial suction blood and its influence on in vitro capillary-pore flow properties in patients undergoing routine coronary artery bypass grafting  Micael Appelblad, ECCP, Gunnar Engström, MD, PhD  The Journal of Thoracic and Cardiovascular Surgery  Volume 124, Issue 2, Pages (August 2002) DOI: /mtc Copyright © 2002 American Association for Thoracic Surgery Terms and Conditions

2 Fig. 1 The blood-processing flow chart shows how blood was subdivided into plasma, plasma-eliminated whole-blood resuspension, and leukocyte/plasma-eliminated erythrocyte resuspension. See text for further details. KRH, Krebs-Ringer-HEPES buffer; hct, hematocrit.

3 Fig. 2 Computer-assisted capillary-pore flow device. The flow of medium through a capillary-pore capillary membrane is driven by constant 600-Pa hydrostatic pressure. The onset and stop is computer controlled with a pneumatic valve and is synchronized with the data output of accumulated weight from a digital balance.

4 Fig. 3 Flow curves of PSB and venous blood plasma. Upper panel, The absolute flow rate versus time shows an obvious acceleration that ends at about 1 second for blank medium. This period is omitted from the calculations, and all presented data refer to the measuring window of 1 to 3 seconds. The 2 curves at the top show the flow curve of buffer (blank flow), whereas that for venous plasma (open circles) and PSB plasma (open squares) demonstrate a depressed flow rate. Lower panel, Each sample is tested versus the blank medium to calculate the relative flow rate, which is indicated. This is the inverse of relative viscosity, although this model is more sensitive to suspended particles and cells. Open and filled circles indicate relative flow of venous plasma in the 2 study groups without and with 30-μm cardiotomy prefiltering, respectively. Open and filled squares indicate relative flow of unfiltered PSB plasma and 30-μm prefiltered PSB plasma, respectively. There are 10 observations in each group. Data points denote mean values ± SEM.

5 Fig. 4 The relative flow curves of PSB and venous whole-blood resuspensions with remaining leukocytes. Upper panel, Open circles and squares indicate flow results without 30-μm cardiotomy prefiltering of venous and PSB blood cells, respectively. Lower panel, Filled circles and squares indicate flow results with 30-μm cardiotomy prefiltering of venous and PSB blood cells, respectively. There are 10 observations in each group. Data points denote mean values ± SEM. The Journal of Thoracic and Cardiovascular Surgery  , DOI: ( /mtc ) Copyright © 2002 American Association for Thoracic Surgery Terms and Conditions

6 Fig. 5 The relative flow curves of PSB and venous erythrocyte resuspensions with eliminated leukocytes. Upper panel, Open circles and squares indicate flow results without 30-μm cardiotomy prefiltering of venous and PSB erythrocytes, respectively. Lower panel, Filled circles and squares indicate flow results with 30-μm cardiotomy prefiltering of venous and PSB erythrocytes, respectively. There are 10 observations in each group. Data points denote mean values ± SEM. The Journal of Thoracic and Cardiovascular Surgery  , DOI: ( /mtc ) Copyright © 2002 American Association for Thoracic Surgery Terms and Conditions

7 Fig. 6 A typical result from the 5-μm filter imprint method: upper panel, venous plasma; lower panel, PSB plasma. A scale bar is depicted at the bottom right of each panel to indicate 100 μm. This PSB-to-venous difference was seen consistently in 5 of 5 test results.
