Why is it important to monitor serum glucose?
Serum glucose levels may affect post-cardiac arrest neurologic function. Animal studies have shown less functional brain recovery after normothermic cerebral ischemia in hyperglycemic animals. The mechanism prob-ably relates to increased lactic acid production secondary to availability of larger amounts of the precursor, glucose. Unfortunately, it is not clear what levels of glucose should be treated. Severe hypoglycemia as a result of overtreatment of hyperglycemia will cause neuronal injury.
