Hyperglycemia can be observed in various neurological and internal dis
eases without diabetes mellitus being present. In a retrospective surv
ey of 100 consecutive patients with spontaneous subarachnoid hemorrhag
e (SAH) a significant prognostic correlation between elevated blood gl
ucose levels and unfavourable outcome could be demonstrated. A rise of
plasma catecholamines, plasma cortisol and growth hormone are discuss
ed as possible reasons for elevated blood glucose levels.
