Subgroup analysis for peak blood lactates and lowest Do2 on CPB
| No HL or HG | HL alone | HG alone | HL and HG | |
| (n = 374) | (n = 4) | (n = 69) | (n = 23) | |
| Peak blood lactate (mmol/l) | 1.27 ± 0.46a | 3.42 ± 0.85b | 1.62 ± 0.61c | 5.82 ± 3.34d |
| Lowest Do2 (ml/minute per m2) | 294 ± 41 | 294 ± 53 | 287 ± 44 | 255 ± 62e |
ap < 0.01 versus the other three groups; bp < 0.01 versus groups HG alone and HL plus HG; cp < 0.01 versus groups HL alone and HL plus HG; dp < 0.01 versus groups HL alone and HG alone; ep < 0.01 versus group no HL or HG and p = 0.014 versus group HG alone. CPB, cardiopulmonary bypass; Do2, oxygen delivery; HG, hyperglycemia; HL, hyperlactatemia.
