Table 3. Differences in cerebral microdialysis markers and PbtO₂ between hypoxic vs. glycolytic lactate pattern (total duration of intracranial monitoring).

Variable	Hypoxic lactate	Glycolytic lactate	P value
Lactate (mmol/L)	4.7±0.7	6.1±2.2	0.05
Pyruvate (μmol/L)	106.8±13.2	186.4±46.3	<0.0001
LPR	40±11	33±11	0.15
Glutamate (μmol/L)	20.3±33.4	16.2±24.3	0.68
PbtO2 (mm Hg)	16.7±3.4	27.2±5.3	<0.0001

LPR, lactate-to-pyruvate ratio; PbtO₂, brain tissue oxygen tension.
