Microdialysate lactate. All values (gray circles) and mean (-) are presented. Lactate values by corrected bronchial microdialysis are corrected by the arteriobronchial urea gradient. * Paired T-test showed significant difference from arterial microdialysis at low steady state (arterial blood lactate ~5 mmol/L) (p < 0.05). † Paired t-test showed significant difference from arterial microdialysis at high steady state (arterial blood lactate ~10 mmol/L) (p < 0.05). ns Non significant from arterial microdialysis at high steady state (arterial blood lactate ~10 mmol/L).
