Management of Ischemic Stroke with Diabetes

Immediate Assessment and Stabilization

The American Heart Association recommends securing airway and providing ventilatory support if the patient has depressed consciousness or airway compromise 3, 4
Administer supplemental oxygen only if hypoxic (oxygen saturation monitoring required) 3, 5
Cardiac monitoring to detect atrial fibrillation and life-threatening arrhythmias is crucial 3, 5
Correct hypotension if present with normal saline and treat underlying causes (volume depletion, cardiac arrhythmias, myocardial ischemia) 3, 4

Check blood glucose immediately via finger stick 3, 4
For hypoglycemia, administer 1 ampule of 50% dextrose immediately, as hypoglycemia can mimic stroke and cause brain injury 3, 6, 4
For hyperglycemia, initiate insulin therapy with target glucose range of 140-180 mg/dL 1, 2, 7
Monitor glucose every 1-2 hours initially, especially if thrombolysis is administered 6, 1

Withhold antihypertensive therapy unless systolic BP >220 mmHg or diastolic BP >120 mmHg 4, 5, 7
Blood pressure must be <185/110 mmHg before rtPA administration 4, 8, 7
Maintain BP ≤180/105 mmHg during and for 24 hours after thrombolysis 7

Intravenous rtPA (0.9 mg/kg, maximum 90 mg) is strongly recommended for eligible patients within 3 hours of symptom onset 9, 5, 7
Time is critical: every 30-minute delay decreases chance of good outcome by 8-14% 7

Do not aggressively lower glucose to <140 mg/dL - increases hypoglycemia risk without benefit 1, 2
Do not give glucose-containing IV fluids - worsens hyperglycemia 5
Do not lower BP precipitously - can extend infarct 3, 4
Do not delay thrombolysis for minor hyperglycemia - time to treatment is paramount, but monitor glucose closely afterward 6, 9
Do not overlook hypoglycemia - can cause permanent brain damage and mimic stroke 3, 6, 8
