No HL or 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

  1. 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.
