  1. ICU: intensive care unit.
  2. RACHS-1: Risk-Adjusted classification for Congenital Heart Surgery Version 1.
  3. CPB: cardiopulmonary bypass.
  4. LacFIRST: lactate level measured at the end of cardiopulmonary bypass.
  5. LacLAST: last measurement of lactate level in the operating room.
  6. LAC:change of lactate level after cardiopulmonary bypass.
