- Background: Hyper- as well as hypoglycemia may be detrimental for brain energy metabolism and even a moderate increase in blood glucose concentration can affect outcome adversely. During physiological conditions, glucose concentration obtained from microdialysis of subcutaneous adipose tissue adequately reflects plasma glucose concentration. This study examines whether this correlation is also obtained during intensive care in patients with severe injuries. Methods.. The study included 62 patients with severe traumatic brain injuries. All patients received one 30 mm microdialysis catheter (CMA 60, CMA Microdialysis) inserted into periumbilical subcutaneous adipose tissue. The probe was perfused (0.3 mul/min) with a Ringer solution from a microinfusion Pump and analyzed for glucose, lactate, and glycerol. The Study included 2.434 simultaneous analyses of glucose concentration in arterial blood and subcutaneous adipose tissue. Results.' The correlation coefficient for glucose concentration in blood and interstitial fluid was 0.743 for the whole material. The cot-relation was relatively poor for 1-6h after insertion of the probes, During this period. a continuous increase in the Subcutaneous level Of glucose and decreases in lactate and glycerol were noted. Conclusions: The correlation between blood glucose concentration and glucose Concentration in subcutaneous adipose tissue was not as good during intensive care as in normal humans. The poor correlation during the first 6h probably reflects a stress reaction (and possibly local vasoconstriction). Microdialysis of subcutaneous adipose tissue permits frequent bedside analyses of the biochemical composition of the extracellular fluid and may be of value during routine intensive care provided the methodological limitations are recognized.
