Subgroup analysis for peak blood lactate and lowest cardiac index (CI) in relation to mixed venous oxygen saturation (SvO2) on cardiopulmonary bypass for group B (n = 250)
| Variable | No HL or HG | HL alone | HG alone | HL and HG |
|---|---|---|---|---|
| No. of patients | 187 | 10 | 21 | 32 |
| Peak blood lactate (mmol/L) | 1.39 ± 0.69 | 3.48 ± 0.38 | 1.79 ± 0.55 | 5.31 ± 3.83 |
| Lowest CI (L/min/m2) | 2.4 ± 0.2 | 2.4 ± 0.1 | 2.4 ± 0.1 | 1.8 ± 0.4 |
| Lowest SvO2 (%) | 80 ± 3 | 73 ± 1 | 72 ± 1 | 55 ± 12 |
Values are presented as mean ± standard deviation. HL, Hyperlactatemia; HG, hyperglycemia; CI, cardiac index; SvO2, mixed venous oxygen saturation.
