The objective of the study was to evaluate significance of hyperglycaemia and cardiac Troponin I (cTnI) after congenital heart surgery in children.
Retrospective cohort study with 279 children. Integrated values (area under the curve (AUC)) were calculated for the first 48 h for cTnI (48h-cTnI). Sustained hyperglycaemia was evaluated with the AUC normalised per hour (48h-Gluc/h). Maximal cTnI, first glucose value (Gluc1), 48h-cTnI and 48h-Gluc/h were correlated with duration of mechanical ventilation, ICU stay and mortality using cut-off values. See tables 1 and 2.
Hyperglycaemia is frequent after cardiac surgery and sustained in the first 48 hours. Admission glycaemia, cTnI max and 48h-cTnI are associated with a higher risk of mortality, prolonged duration of mechanical ventilation and prolonged length of stay in ICU.
