Brain energy metabolic crisis (MC) and lactate-pyruvate ratio (LPR) elevations have been linked to poor outcome in comatose patients. We sought to determine if MC and LPR elevations after subarachnoid hemorrhage (SAH) are associated with acute reductions in serum glucose. ⋯ Acute reductions in serum glucose, even to levels within the normal range, may be associated with brain energy metabolic crisis and LPR elevation in poor-grade SAH patients.
