Fig. 1 Mean ± SD values of central and peripheral temperatures, oxygen consumption, oxygen delivery, oxygen extraction, and arterial blood lactate levels during the first 4 hours after admission to the pediatric intensive care unit after cardiac bypass operations in 20 children. In the panel concerning temperatures, the solid line indicates central temperature, and the dotted line indicates peripheral temperature.

Fig. 2 The relationships between peak increase in VO2 and peak increase in central and peripheral temperatures (top), between peak increase in VO2 and peak increase in DO2(bottom, left), and between peak increase in VO2 and the change in oxygen extraction at the time of peak VO2(bottom, right) during the first 4 hours after admission to the pediatric intensive care unit after cardiac bypass operation in 20 children.

Fig. 3 The relationship between oxygen consumption and age when central temperature was closest to 37°C during the first 4 hours after admission to the pediatric intensive care unit after cardiac bypass operations in 20 children. In the 18 patients older than 3 months (filled circles) , it shows a trend with a y value of –3.8155x + 177.34 and an r value of –0.756. The other 2 patients younger than 3 months (open circles) had a significantly lower VO2.
