Targeted insulin therapy for glycemic control might on the contrary have harmful effects by causing too low cerebral glucose levels. The study published by Schlenk and colleagues in the previous issue of Critical Care shows that insulin caused a significant decrease in the interstitial cerebral glucose concentration although the blood glucose level remained unaffected. Since several studies utilizing various analytical techniques have shown that cerebral blood flow and cerebral glucose uptake and metabolism are insulin-independent processes the observation remains unexplained. The study published by Schlenk and colleagues in the previous issue of Critical Care was initiated by clinical experience that after subarachnoid hemorrhage hyperglycemia is strongly associated with complications and impaired neurological recovery. Utilizing intracerebral microdialysis and bedside biochemical monitoring Schlenk and colleagues made the unexpected observation that insulin caused a significant decrease in the interstitial cerebral glucose concentration although the blood glucose level remained unaffected 1 . The technique of microdialysis was introduced more than 30 years ago for monitoring the animal brain and has become a standard technique in neuroscience with well over 11 000 publications 2 3 . .
