Designing a new scoring system (QualyP Score) correlating the management of cardiopulmonary bypass to postoperative outcomes.

Aim: The aim of this study was to ascertain if a score, directly derived from CPB records, could correlate to major postoperative outcomes.

Methods: An additive score (QualyP Score) was created from 10 parameters: peak lactate value during CPB, peak VCO(2)i, lowest DO(2)i/VCO(2)i, peak respiratory quotient, CPB time, cross-clamp time, lowest CPB temperature, circulatory arrest, ultrafiltration during CPB, number of packed red cells transfused intraoperatively. The PerfSCORE was calculated, as well.
