A 62-year-old male with a history of hypertension and hyperlipidemia presents with sudden onset of right-sided weakness, facial droop, and slurred speech that began 45 minutes ago. His blood glucose is 98 mg/dL. What is the most critical prehospital intervention for this patient?
- AObtain an accurate last known normal (LKN) time.
- BTransport to the nearest stroke-capable facility for thrombolytic consideration.
- CAdminister aspirin 325 mg orally.
- DInitiate aggressive blood pressure control.
Show answer & explanationAnswer & explanation
Correct answer: B. Transport to the nearest stroke-capable facility for thrombolytic consideration.
The patient's sudden onset of neurological deficits (right-sided weakness, facial droop, slurred speech) with a normal blood glucose is highly suggestive of an acute ischemic stroke. The most time-sensitive and critical prehospital intervention is rapid identification and transport to a stroke-capable facility for evaluation for thrombolytic therapy (tPA) or endovascular thrombectomy, as these treatments are highly time-dependent.
Why the other options are wrong
- A. While obtaining an accurate LKN time is crucial for hospital decision-making regarding thrombolytics, it is part of the assessment and history-taking, not the 'most critical intervention' itself, which is expediting definitive care.
- C. Aspirin is generally contraindicated until hemorrhagic stroke is ruled out by CT scan in the hospital. Administering it prehospital could worsen outcomes in a hemorrhagic stroke.
- D. Aggressive blood pressure control in acute ischemic stroke can worsen cerebral perfusion and is generally avoided in the prehospital setting unless BP is extremely high (e.g., >220/120 mmHg) or there is evidence of other end-organ damage.
Acute Stroke Management
Prehospital management of acute stroke focuses on rapid identification using a stroke scale, establishing last known normal time, and immediate transport to a stroke-capable facility for time-sensitive reperfusion therapies.
- Time is brain: every minute counts.
- Key assessment: Last Known Normal (LKN) time.
- Rapid transport to a designated stroke center is paramount.
- Avoid aspirin until hemorrhagic stroke is ruled out.
