A drinking tube was fabricated with a piece of 8 or 10 mm O.D. glass tubing. It gives accurate measurement of the volume of liquid consumed by small birds and mammals. The tube can be readily cleaned and autoclaved.
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.
