Brief Summary:

We evaluate the relationship between the regional tissue oxygenation value (ScO2 - cerebral, StO2 - lower limb) and mixed venous saturation (SvO2) and arterial oxygen saturation (SaO2) measured before and after correction surgery in pediatric patients undergoing cardiac surgery.

In addition, we compared the sCO2 and sTO2 with reference value which is calculated using SvO2 and SaO2.

Experimental: Children with congenital cardiac disease
Pediatric patients aged < 7 years undergoing cardiac surgery
Device: Masimo O3

After anesthesia induction, a masimo O3 sensors are attached to the forehead (ScO2) and the sole of the foot (StO2). About 0.4 ml blood samples are obtained from arterial line and central venous line at three epochs before and after cardiopulmonary bypass (total 6 times)

  • T1: before cardiopulmonary bypass (CPB), fraction of inspired oxygen (FiO2) 0.2
  • T2: before CPB, FiO2 0.5
  • T3: before CPB, FiO2 0.8
  • T4: after CPB, FiO2 0.8
  • T5: after CPB, FiO2 0.5
  • T6: after CPB, FiO2 0.2

Hemoglobin oxygen saturation values are confirmed in each sample (arterial sample: SaO2, venous sample: SvO2). Each O3 values (ScO2 and StO2) are compared to the values of SvO2, 0.7 × SvO2 + 0.3 × SaO2.

Primary Outcome Measures :
  1. Validation of Masimo O3 value [ Time Frame: During surgery ]
    Comparison of ScO2 and StO2 to reference level (SvO2, 0.7×SvO2 + 0.3×SaO2)
