To test for stroke probability, instruct the patient to show their teeth or smile. Evaluate for facial droop. It is abnormal if one side of the face does not move as well as the other. Next, evaluate arm drift. Instruct the patient to close their eyes and extend both arms straight out, with the palms up for 10 seconds. It is abnormal if one arm does not move or one arm drifts down compared with the other. Third, evaluate for abnormal speech. Have the patient say “you can’t teach an old dog new tricks.” It is abnormal if the patient slurs words, uses the wrong words, or is unable to speak. If any one of the 3 signs is abnormal, the probability of a stroke is 72%.

Identify signs and symptoms of a possible stroke and activate the emergency response system. 

Pre-hospital interventions by EMS will focus on supporting ABCs and giving oxygen if indicated, performing a prehospital stroke assessment using an approved tool such as the Cincinnati Stroke Scale, checking glucose, establishing time of symptom onset (or last seen normal), triaging to a stroke center, and alerting the hospital to activate the stroke team. 

Within 10 minutes of ED arrival perform immediate general assessment within 10 minutes of patient arrival to the ED and stabilize ABCs if necessary. Provide oxygen therapy if hypoxic. Obtain IV access and perform laboratory assessments. 

Check glucose and treat if indicated. Obtain a 12-lead ECG and perform neurologic screening assessment. Do not delay CT, obtain CT without contrast within 20 minutes of patient arrival. 

A neurologic assessment by the stroke team or designee should be done within 20 minutes of patient arrival to the ED. Review patient history, establish the time of symptom onset or last known normal, and perform a neurological examination using a standardized tool such as the NIH Stroke Scan or Canadian Neurological Scale. 

If the CT scan shows hemorrhage, consult a neurologist or neurosurgeon and consider a transfer. Begin stroke or hemorrhage pathway. Admit to a stroke unit or intensive care. 

If the CT scan shows no hemorrhage, consider fibrinolytic therapy. Check the fibrinolytic exclusions, repeat the neurologic exam to determine if symptoms are improving or worsening. 

Candidates with the onset of symptoms within 3 hours or 4.5 hours in selected patients are eligible.

If the patient is a candidate for rTPA review the risks and benefits with the patient and family. Begin fibrinolytic therapy within 60 minutes of patient arrival to the ED. Consider endovascular therapy for the onset of symptoms up to 24 hours and large vessel occlusion. Admit the patient to stroke care within 3 hours of arrival to the ED. 

Begin post-rTPA stroke care. Monitor blood pressure and neurological symptoms. Monitor for adverse reactions to fibrinolytic therapy.

Interventions Within 10 Minutes of Arrival

The receiving hospital should have a written plan for receiving and treating suspected stroke victims. Any plan should emphasize minimizing the delay in diagnosis and treatment of the patient.

Once a suspected stroke patient has arrived at the emergency department (ED), they should be assessed by a qualified healthcare professional within 10 minutes.

Interventions and assessments that should take place after arrival at the ED include:

  • Neurological Screening: The neurological screening should be performed within 10 minutes of arrival. The NIH stroke scale is a 15-item screening tool used to determine stroke and stroke severity. The neurologic screening (NIH stroke scale) is more complex than the Cincinnati Stroke Scale that is used in the out-of-hospital setting.
  • Order Head CT scan: After obtaining a positive stroke screening, the head CT scan should be ordered (*See Note). No other interventions that are non-life-threatening should delay the CT scan, and the scan should be read by a qualified physician ASAP. (Note: Established stroke protocols in hospitals utilizing an ED triage may allow EMS providers to transport eligible stroke patients directly to CT or MRI and bypass ED admission. Bypassing ED admission for the initial neurologic examination and brain imaging is a best practice strategy for rapid stroke care.)
  • Assess and treat ABCs: Upon arrival airway maintenance and cardiovascular status should be assessed and monitored to rule out any underlying life-threatening conditions. Interventions should include a 12-lead ECG to rule out myocardial infarction and arrhythmias. Apply oxygen if necessary to maintain oxygen saturation greater than 94%. Also, IV access can be established at this time if not already completed.
  • Activate the stroke team or qualified expert: By the time the CT scan is completed, the stroke team should be ready to perform the rest of the interventions in the stroke pathway if indicated. These interventions include: reading the CT, full neurological assessment, administration of fibrinolytic therapy, and admission to a stroke unit.
  • Blood Glucose: If not completed prior to ED arrival, a blood glucose should be obtained to rule out hypoglycemia.

All of the above interventions should take place within 10 minutes of hospital arrival.

Which test should be performed for a patient with suspected stroke?

The 2 main types of scan used to assess the brain in people who have had a suspected stroke are: a CT scan. an MRI scan.

Which of these tests should be performed for a patient with suspected stroke within 20 minutes of hospital arrival?

Obtain a 12-lead ECG and perform neurologic screening assessment. Do not delay CT, obtain CT without contrast within 20 minutes of patient arrival. A neurologic assessment by the stroke team or designee should be done within 20 minutes of patient arrival to the ED.

Which of these tests should be performed for a patient with suspected stroke as early possible but no more than 20 mins after hospital arrival?

Patients with suspected strokes must be assessed within 10 minutes of arrival in the emergency department by the stroke team and other experts. Within 10-25 minutes, the CT scan must be completed, and within 45 minutes it must be read.

What additional assessment and stabilization activities should be completed within the first 10 min?

Immediate general assessment and stabilization. Once the patient has arrived at the emergency department, and within 10 minutes of arrival, assess the vitals, providing oxygen if the patient is hypoxemic.
