Key result
Varying hematocrit in rats with cerebral ischemia showed a U-shaped correlation with brain lactate, where very low hematocrit (<30%) caused the greatest lactate increase (p<0.0001).
Why the study?
Does varying hematocrit levels affect brain metabolism in spontaneously hypertensive rats with experimentally induced cerebral ischemia?

In a rat model of cerebral ischemia, brain metabolism impairment shows a U-shaped relationship with hematocrit, being most severe at very low (<30%) and high (≥50%) hematocrit levels.

Hematocrit extremes may worsen cerebral metabolism in ischemia; hypothesis-generating for optimal targets in human stroke trials.
Kiyohara et al. (1985) studied Experimentally induced cerebral ischemia. Hematocrit variation vs. Normal hematocrit (40-49%) was evaluated on Brain tissue lactate, pyruvate, and adenosine triphosphate (ATP) (p=<0.0001). Varying hematocrit in rats with cerebral ischemia showed a U-shaped correlation with brain lactate, where very low hematocrit (<30%) caused the greatest lactate increase (p<0.0001).
