Management of Suspected Stroke: A Comprehensive Approach
Immediate activation of emergency medical services (911) is the first and most critical step in the management of a patient suspected of having a stroke, as time is brain tissue and rapid intervention significantly impacts morbidity and mortality outcomes.
Initial Prehospital Management
Recognition and Assessment
- Use standardized stroke screening tools that include FAST (Face, Arm, Speech, Time) components 1
- For positive FAST screens, perform a second validated stroke severity assessment to identify possible endovascular treatment candidates 1
- Document critical information:
On-Scene Management
- Keep on-scene time as short as possible (target median ≤20 minutes) for patients within treatment window 1
- Optimize out-of-hospital care by:
Transport Decisions
- EMS should bypass hospitals that cannot treat stroke and transport to the closest facility capable of providing appropriate stroke care 1
- Direct transport protocols should consider:
Emergency Department Management
Immediate Assessment
- Triage suspected stroke patients as high priority (CTAS Level 2 in most cases, Level 1 if compromised ABCs) 1
- Perform rapid assessment of:
Diagnostic Imaging
- Urgent non-contrast CT scan within 25 minutes of arrival to distinguish between ischemic and hemorrhagic stroke 2
- CT angiography from aortic arch to vertex to identify large vessel occlusions 2
- Vascular imaging to identify significant symptomatic extracranial carotid artery stenosis 2
Laboratory Testing
- Order critical laboratory tests:
Acute Interventions
Thrombolytic Therapy
- IV thrombolysis (alteplase) for eligible patients within 4.5 hours of symptom onset 2
- Dose: 0.9 mg/kg (maximum 90 mg)
- Ensure BP <185/110 mmHg before administration
Endovascular Treatment
- Consider endovascular thrombectomy for large vessel occlusion 2
- Can be considered up to 24 hours with evidence of salvageable brain tissue
Blood Pressure Management
- For patients receiving thrombolysis: maintain BP <185/110 mmHg 2
- For patients not receiving thrombolysis: individualized BP management based on stroke type and comorbidities
Antiplatelet Therapy
- Administer aspirin (160-325 mg) within 48 hours of ischemic stroke onset, but only after hemorrhage is ruled out by imaging 2
In-Hospital Management
Specialized Care
- Transfer patients to a specialized stroke unit as soon as possible 2
- Implement continuous monitoring of vital signs and neurological status 2
- Initiate early mobilization by rehabilitation professionals within 48 hours of admission 2
Secondary Prevention
- For patients with atrial fibrillation:
- Initiate anticoagulation therapy (warfarin with target INR 2.0-3.0 or direct oral anticoagulants) 3
- Implement statin therapy for lipid management 2
- Control hypertension with appropriate medications 2
Management of Complications
- Treat seizures with short-acting medications if not self-limiting 2
- Manage fever with temperature reduction measures and investigate for possible infection 2
- Consider neurosurgical consultation for extensive MCA territory ischemic stroke 2
Common Pitfalls to Avoid
- Delaying activation of emergency services - remember "time is brain tissue" 4
- Failing to document the time of symptom onset or last known well, which is critical for treatment eligibility 1
- Missing stroke mimics such as hypoglycemia, seizures, migraines, or toxic-metabolic disorders 1
- Inadequate blood pressure management before thrombolytic therapy
- Delaying transfer to specialized stroke centers, which can improve mortality and morbidity by up to 20% 5
By following this comprehensive, time-sensitive approach to stroke management, healthcare providers can significantly improve patient outcomes by reducing mortality, minimizing disability, and enhancing quality of life for stroke survivors.
