The objective of this study was to determine the changes in blood viscoelasticity during and after pediatric cardiopulmonary bypass (CPB) procedures. 12 pediatric cardiac patients, subjected to hypothermic (22oC to 28oC) CPB procedures were enrolled in this study. Viscosity and elasticity were measured at strains of 0.2, 1, and 5 using a Vilastic-3 Viscoelasticity Analyzer. Viscosity and elasticity at strains of 0.2, 1, and 5 were significantly altered during hypothermic CPB and 1 hour after CPB. To the best of our knowledge, these are the first results ever presented on blood viscoelasticity during and after pediatric cardiopulmonary bypass procedures.
