Metabolic abnormalities occur after traumatic brain injury (TBI). Glucose is conventionally regarded as the major energy substrate, although lactate can also be an energy source. We compared 3-13C lactate metabolism in TBI with "normal" control brain and muscle, measuring 13C-glutamine enrichment to assess tricarboxylic acid (TCA) cycle metabolism. Microdialysis catheters in 9 severe TBI patients' brains, 5 non-TBI brain surgical patients, and 5 resting muscle (non-TBI) patients were perfused (24h in brain, 8h in muscle) with 8 mmol/L sodium 3‑13C lactate...
