Hyperglycaemia (high blood sugar) is common in stroke patients and linked to worse outcomes. While intensive glucose control may help, more research is needed for stroke patients regarding insulin therapy benefits and risks.

Area of Science:

  • Neurology
  • Endocrinology
  • Critical Care Medicine

Background:

  • Diabetes and hyperglycemia are prevalent in acute stroke patients.
  • Hyperglycemia is associated with poorer stroke outcomes and increased risk of hemorrhagic transformation.

Purpose of the Study:

  • To review the evidence for and against intensive glucose control in acute stroke patients.
  • To discuss the risks and benefits of insulin administration for hyperglycemia in stroke.

Main Methods:

  • Review of existing literature on hyperglycemia in stroke.
  • Analysis of evidence from intensive care units and extrapolation to stroke patients.
  • Comparison of European and American guidelines for glucose control in stroke.

Main Results:

  • Hyperglycemia is linked to poor stroke outcomes, but thrombolysis effectiveness is not affected by blood sugar levels.
  • Evidence for intensive glucose control benefits in stroke is limited, unlike in general ICU patients.
  • Both glucose-potassium-insulin infusion and adjusted insulin infusions are effective but carry a risk of hypoglycemia.

Conclusions:

  • While European guidelines suggest glucose control for stroke patients (threshold 10 mmol/l), American guidelines are less defined.
  • Insulin therapy for hyperglycemia in stroke requires careful consideration of benefits versus the risk of hypoglycemia.
  • Implementing a locally approved regimen for glucose management in acute stroke is advisable.
