Further decrease in subclinical hemolysis utilizing 12.7 mm tubing in the arterial roller head
KA Crane, D Brown, R Anderson and KM Begelman
In a series of 20 consecutive perfusions done for the same surgeon, 9.54 mm
tubing was used in 10 coronary artery bypass grafting (CABG) procedures
(Group 1), and 12.7 mm (1/2 in) internal diameter tubing was used in 8 CABG
operations and 2 single valve replacements (Group 2). Extracorporeal
circulation techniques were otherwise identical in all procedures. While no
statistically significant differences between Group 1 and Group 2 were
noted for pump time or platelet counts, it was observed that the patients
undergoing perfusions with 12.7 mm internal diameter tubing showed
significantly less hemolysis.
