Tip This Week- Post-Stroke Care & Hyperglycemia
The incidence of post-stroke stress hyperglycemia is causing many care providers to very carefully manage the blood glucose levels in these critical patients. Studies have shown increased infarction growth and poorer outcomes for patients with post stroke hyperglycemia that for those with normal blood sugar levels.
This should not be a surprise to anyone when you look at the physiology associated with the body’s stress reaction (sympathetic nervous system). However, while you need more blood sugar in your system when preparing to run from a tiger, the evolutionary reason for the response, this doesn’t translate when talking about attacks on the brain associated with either ischemic or hemorrhagic strokes.
High blood sugar encourages metabolic acidosis and may facilitate broader cell lysis during times of injury. Additionally, alterations in blood chemistry may hinder clotting during hemorrhagic strokes (yet to be studied and reviewed but certainly valid based on understandings about physiology).
Check out the additional stroke resources you’ll find below.
