Acute Stroke Management Guidelines

Immediate Prehospital Management

The American Heart Association recommends activating emergency medical services (EMS) immediately upon recognition of stroke symptoms using the FAST assessment, as EMS transport significantly reduces time to stroke team activation by approximately 8 minutes compared to private transportation 1, 2
Document the exact time of symptom onset or last known normal during initial assessment, as this determines eligibility for time-sensitive interventions like thrombolysis (effective within 4.5 hours) 3, 4

Emergency Department Protocol (First 60 Minutes)

Obtain non-contrast CT or MRI within 30 minutes of arrival to differentiate ischemic stroke, hemorrhagic stroke, and stroke mimics—this is the only definitive method to guide treatment 5, 1
Perform CT angiography or MR angiography from aortic arch to vertex within 24 hours to identify large vessel occlusions amenable to mechanical thrombectomy 5

Acute Treatment Phase

Administer intravenous tissue plasminogen activator (tPA) with door-to-needle time <60 minutes for eligible ischemic stroke patients presenting within 4.5 hours of symptom onset, as earlier treatment (0-90 minutes) provides number-needed-to-treat of 4.5 compared to 14.1 for later treatment (181-270 minutes) 4
Admit all stroke patients to a geographically defined stroke unit staffed by a dedicated multidisciplinary team including neurologists, specialized nurses, physiotherapists, occupational therapists, speech therapists, and social workers 6, 4, 7

Prevention of Acute Complications

Monitor closely for cerebral edema (peaks 3-4 days post-stroke but can occur within 24 hours with reperfusion), particularly in large hemispheric or posterior fossa infarctions requiring potential neurosurgical intervention 3
Implement swallowing screening before oral intake to prevent aspiration pneumonia, which is a compulsory quality indicator 6, 4

Secondary Prevention Strategies

Initiate antiplatelet therapy at discharge for ischemic stroke patients (compulsory quality indicator) 6, 4
Start anticoagulation at discharge for patients with atrial fibrillation (compulsory quality indicator) 6, 4
Perform carotid revascularization for ≥50% symptomatic carotid stenosis according to NASCET criteria 6

Quality Indicators and System Requirements

The European Stroke Organisation mandates six compulsory quality indicators, including door-to-needle time <60 minutes for thrombolysis patients, all acute stroke patients admitted to stroke unit or ICU, brain imaging (CT/MRI) in every suspected stroke, antiplatelet therapy at discharge for ischemic stroke, anticoagulation at discharge for atrial fibrillation patients, and swallowing disorder screening for all patients 6, 4
Ensure 24/7 availability of CT/MRI, CT angiography, neurosurgery, vascular surgery, interventional neuroradiology, and cardiology consultation 6, 4

Rehabilitation and Discharge Planning

Conduct standardized screening evaluation during initial hospitalization to identify patients with residual impairments requiring rehabilitation 7
Initiate rehabilitation planning involving caregivers within 24 hours, as 50-70% of patients regain functional independence but 15-30% remain permanently disabled 8, 7
Provide structured patient and family education about stroke causes, risk factors, warning signs, secondary prevention strategies, and proper EMS activation before discharge 8, 7, 9

Evidence‑Based Acute Stroke Management Practices

Prehospital and Early Emergency Assessment

Determining the exact “last known well” time is critical because it defines eligibility for intravenous thrombolysis (≤ 4.5 h) and for mechanical thrombectomy (up to 24 h in selected patients)【10】【11】.
Supplemental oxygen should be administered only when peripheral oxygen saturation falls below 94 %【10】.
Immediate bedside capillary glucose measurement is required; glucose‑containing fluids should be avoided unless the patient is hypoglycaemic【10】【12】.

Emergency Department Laboratory Evaluation

A core laboratory panel—including glucose, electrolytes, renal function, complete blood count with platelets, cardiac biomarkers, PT/INR, and aPTT—should be obtained, but thrombolytic therapy must not be delayed while awaiting results unless there is clinical suspicion of a bleeding disorder, thrombocytopenia, or recent anticoagulant use【12】.

Stroke‑Unit Staffing and Early Clinical Course

The stroke unit should maintain a nurse‑to‑patient ratio of 1:2 for the first 24 hours; up to 30 % of patients experience neurological deterioration during this period【13】.

Antiplatelet Therapy Timing

In patients who receive intravenous alteplase, oral aspirin should be postponed until more than 24 hours after thrombolysis to minimize the risk of intracerebral hemorrhage【14】.

Venous Thrombo‑Embolism (VTE) Prophylaxis

Subcutaneous unfractionated heparin 5 000 IU twice daily or low‑molecular‑weight heparin provides superior VTE prophylaxis compared with mechanical methods alone in immobilized stroke patients【14】.
Intermittent pneumatic compression further reduces VTE risk (and may lower mortality), whereas routine use of anti‑embolic stockings is not recommended【14】.

Aspiration‑Prevention Measures

For patients unable to swallow, a naso‑enteric feeding tube should be placed within 24 hours; it is preferred over percutaneous endoscopic gastrostomy for the first 2–3 weeks【14】.
Performing oral hygiene at least three times daily and immediately after meals decreases the incidence of aspiration pneumonia【14】.

Early Mobilization

Neurologically and hemodynamically stable patients should be mobilized within 24 hours of admission (ideally ≤ 52 hours); early mobilization is associated with fewer medical complications【14】.

Fluid and Volume Management

Euvolemia should be maintained with isotonic normal saline; the use of volume expanders to achieve hemodilution is not recommended【14】.

Indwelling Devices and Pressure‑Area Care

Routine placement of indwelling urinary catheters should be avoided because of the heightened infection risk【14】.
High‑risk patients should receive pressure‑area care using high‑specification foam mattresses to prevent pressure injuries【14】.

Guideline Recommendations for Acute Ischemic Stroke Treatment in Elderly Patients

Immediate Acute Management

Imaging and Eligibility Assessment

Perform non‑contrast CT or MRI within 30 minutes of hospital arrival to exclude intracerebral hemorrhage before any reperfusion therapy. Class I, Level A (American Heart Association/American Stroke Association). 15
Obtain CT‑angiography or MR‑angiography from the aortic arch to the vertex to identify large‑vessel occlusion (LVO) that would qualify the patient for mechanical thrombectomy. Class I, Level A. 15

Intravenous Thrombolysis (IV alteplase)

Administer IV alteplase 0.9 mg/kg (max 90 mg) with 10 % as an immediate bolus and the remaining 90 % infused over 60 minutes; aim for a door‑to‑needle time < 60 minutes. Class I, Level A. 16
0–3 hours from symptom onset: strong recommendation for IV alteplase (Class I, Level A). [15][17]
3–4.5 hours from onset: IV alteplase is recommended provided additional exclusion criteria are met (age > 80 yr, use of oral anticoagulants regardless of INR, NIHSS > 25, or prior stroke + diabetes). Class I, Level B. 17
> 4.5 hours from onset: IV alteplase is not recommended. Class III, Level A. 17
Contraindication: frank hypodensity involving > 1/3 of the MCA territory on CT mandates withholding alteplase (Class III, Level A). 15

Mechanical Thrombectomy (MT)

Age alone is not a contraindication to MT; patients ≥ 80 years derive significant benefit (common odds ratio 3.68; 95 % CI 1.95‑6.92). Class I, Level A. 16
Indications for MT (Class I, Level A):
For M2/M3, vertebral/basilar, or posterior cerebral artery occlusions, MT may be reasonable (Class IIb, Level B). 16

Intra‑arterial Thrombolysis (IAT)

Consider intra‑arterial alteplase as rescue therapy within 6 hours for patients with proximal large‑vessel occlusions who are ineligible for IV alteplase. Class IIa, Level B. 17

In‑Hospital Acute Management

Antiplatelet Therapy

Give aspirin 160‑325 mg within 48 hours of stroke onset after imaging excludes hemorrhage. Class I, Level A. [15][17]
Aspirin is superior to therapeutic parenteral anticoagulation for acute ischemic stroke. Class I, Level B. 17

Anticoagulation

Routine anticoagulation (unfractionated heparin or LMWH) is not recommended in unselected acute ischemic stroke patients because harms outweigh benefits. Class III, Level A. [18][17]

Venous Thrombo‑embolism (VTE) Prophylaxis

Use subcutaneous low‑molecular‑weight heparin (e.g., 5 000 IU twice daily) rather than unfractionated heparin for pharmacologic prophylaxis. Class I, Level B. 17
Add intermittent pneumatic compression for additional VTE risk reduction. Class I, Level B.
Elastic compression stockings are not recommended for routine VTE prophylaxis. Class III, Level A. 17

Secondary Prevention

Antithrombotic Therapy

Non‑cardioembolic stroke: prescribe clopidogrel 75 mg daily or aspirin + extended‑release dipyridamole (25 mg/200 mg twice daily) rather than aspirin alone; these regimens are superior for preventing recurrent stroke. Class I, Level A. 17
Atrial fibrillation: initiate oral anticoagulation at discharge (quality indicator). Oral anticoagulants are superior to antiplatelet agents for preventing cardioembolic recurrence. Class I, Level A. [19][17]
Minor stroke (NIHSS ≤ 3‑5) or high‑risk TIA (ABCD2 ≥ 4): start dual antiplatelet therapy (aspirin + clopidogrel or ticagrelor) within 24 hours of symptom onset. Class I, Level B. 19

Blood Pressure Management

Start antihypertensive medication in all patients regardless of baseline BP; BP control is a compulsory quality indicator. Class I, Level A. [18][19]

Lipid Management

Prescribe a high‑intensity statin for all patients with ischemic stroke or TIA. Class I, Level A. [18][17]
Target LDL‑cholesterol < 1.8 mmol/L (≈70 mg/dL). Class I, Level B. 19

Carotid Revascularization

For symptomatic carotid stenosis ≥ 50 % (NASCET criteria), perform carotid endarterectomy within 14 days of symptom onset. Class I, Level A. 19

Lifestyle Modifications

Provide smoking‑cessation counseling to active smokers. Class I, Level B. 19
Advise alcohol reduction to ≤ 2 drinks/day (men) or ≤ 1 drink/day (women). Class I, Level B. 19
Recommend low‑ to moderate‑intensity aerobic activity (≈10 min, ≥ 4 days/week). Class I, Level B. 19
Counsel on dietary sodium < 2000 mg/day. Class I, Level B. 19

Discharge Planning and Follow‑up

Arrange specialist stroke‑rehabilitation team follow‑up within 72 hours of discharge. Class I, Level A. 19
Review health and social‑care needs at 6 months and then annually (including patients in care homes). Class I, Level A. 19

Evidence‑Based Acute Management of Ischemic Stroke

Acute Reperfusion Therapy

Intravenous alteplase (0.9 mg/kg, max 90 mg; 10 % bolus, remainder over 60 min) should be administered within 4.5 h of symptom onset in eligible patients, with a target door‑to‑needle time < 60 min. 20
Mechanical thrombectomy is indicated for proximal MCA (M1) occlusion in patients with pre‑stroke functional status mRS 0‑1, NIHSS ≥ 6, ASPECTS ≥ 6, and groin puncture ≤ 6 h from onset; the procedure may be performed with or without prior IV alteplase. 20

Vascular Imaging

CT angiography from the aortic arch to the vertex should be obtained emergently to identify large‑vessel occlusion amenable to thrombectomy. 20

Endovascular Rescue

Intra‑arterial thrombolysis can be considered as rescue therapy within 6 h of onset for MCA occlusion when the patient is ineligible for IV alteplase. [21][22]

Cardiac Monitoring in Right‑Hemisphere Stroke

Right‑middle‑cerebral‑artery strokes carry a higher risk of cardiovascular complications (myocardial ischemia, atrial fibrillation, arrhythmias); continuous cardiac monitoring for the first 24 h is recommended to detect intermittent arrhythmias. 23

Deep‑Vein Thrombosis (DVT) Prophylaxis

Subcutaneous low‑molecular‑weight heparin (e.g., enoxaparin 40 mg once daily) is more effective than unfractionated heparin 5,000 IU twice daily for preventing DVT/PE in acute stroke patients. 23

Additional Monitoring

Continuous cardiac telemetry for the initial 24 h helps identify new‑onset atrial fibrillation and other arrhythmias that may influence secondary‑prevention decisions. 23
