data, elevated glucose level showed negative correlations with CO and DO2, and positive correlations with SVR and ERO2 (Figure 13) (Zhang 2008). Therefore, hyperglycemia is

hours after the Norwood procedure for 17 neonates in the ICU.

To date, we have found a few factors in current routine postoperative management that have varied effects on oxygen transport. Further investigations are required to identify other factors in clinical management with favourable or adverse effects, and to design new treatment strategies to improve postoperative oxygen transport and clinical outcomes.
