What blood glucose level should prompt the administration of IV or SQ insulin for a patient with acute ischemic stroke?

The administration of IV or subcutaneous (SQ) insulin in the context of an acute ischemic stroke is typically considered when a patient's blood glucose level reaches 180 mg/dL or higher. This threshold is significant because elevated blood glucose levels can have detrimental effects in stroke patients, including increased infarct size and a worse overall prognosis.

Maintaining optimal glucose levels is essential in the management of stroke, as hyperglycemia can exacerbate brain injury and negatively influence recovery. Therefore, the choice of 180 mg/dL aligns with the guidelines that advise treatment for hyperglycemia in these critical situations. It ensures that healthcare providers are addressing potential complications associated with high blood sugar levels while managing the acute presentation of an ischemic stroke.
