Interventions Within 10 Minutes of ArrivalThe 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:
All of the above interventions should take place within 10 minutes of hospital arrival.

Stroke is a condition in which normal blood flow to the brain is interrupted. Strokes can occur in two variations: ischemic and hemorrhagic. In ischemic stroke, a clot lodges in one of the brain’s blood vessels, blocking blood flow through the blood vessel. In hemorrhagic stroke, a blood vessel in the brain ruptures, spilling blood into the brain tissue. Ischemic stroke and hemorrhagic stroke account for 87% and 13% of the total incidents, respectively. In general, the symptoms of ischemic and hemorrhagic strokes are similar. However, the treatments are very different. Symptoms of Stroke
• Use four liters per minute nasal cannula; titrate as needed to keep oxygen saturation to 94-99 percent. • Check glucose; hypoglycemia can mimic acute stroke • Determine precise time of symptom onset from patient and witnesses • Determine patient deficits (gross motor, gross sensory, cranial nerves) • Institute seizure precautions
• At least two large gauge IVs in each antecubital fossa. • Take to stroke center if possible Clinical signs of stroke depend on the region of the brain affected by decreased or blocked blood flow. Signs and symptoms can include: weakness or numbness of the face, arm, or leg, difficulty walking, difficulty with balance, vision loss, slurred or absent speech, facial droop, headache, vomiting, and change in level of consciousness. Not all of these symptoms are present, and the exam findings depend on the cerebral artery affected. The Cincinnati Prehospital Stroke Scale (CPSS) is used to diagnose the presence of stroke in an individual if any of the following physical findings are seen: facial droop, arm drift, or abnormal speech. Individuals with one of these three findings as a new event have a 72% probability of an ischemic stroke. If all three findings are present, the probability of an acute stroke is more than 85%. Becoming familiar and proficient with the tool FAST utilized by the rescuers’ EMS system is recommended. Mock scenarios and practice will facilitate the use of these valuable screening tools. FAST: Face Drooping, Arm Weakness, Speech, and Time Symptoms Started Individuals with ischemic stroke who are not candidates for fibrinolytic therapy should receive aspirin unless contraindicated by true allergy to aspirin. All individuals with confirmed stroke should be admitted to Neurologic Intensive Care Unit if available. Stroke treatment includes blood pressure monitoring and regulation per protocol, seizure precautions, frequent neurological checks, airway support as needed, physical/occupational/speech therapy evaluation, body temperature checks, and blood glucose monitoring. Individuals who received fibrinolytic therapy should be followed for signs of bleeding or hemorrhage. Certain individuals (age 18 to 79 years with mild to moderate stroke) may be able to receive tPA (tissue plasminogen activator) up to 4.5 hours after symptom onset. Under certain circumstances, intra-arterial tPA is possible up to six hours after symptom onset. When the time of symptom onset is unknown, it is considered an automatic exclusion for tPA. If time of symptom onset is known, the National Institute of Neurological Disorders and Stroke (NINDS) has established the time goals below.
Emergency Department Staff
OxygenConfirm time of symptom onset Perform targeted neurological exam Complete fibrinolytic checklist Which is the time goal metric of 45 minutes after arrival to ED?The CT scan should be completed within 10-25 minutes of the individual's arrival in the ED and should be read within 45 minutes.
How many hours of the onset of symptoms should fibrinolytic therapy be initiated?For optimal results, fibrinolytic therapy should be administered as early as possible, preferably within the first 3 to 6 hours and potentially up to 12 hours after the onset of symptoms (Figure I in the Data Supplement). After 3 hours of symptom onset the clinical benefit of fibrinolysis markedly decreases.
What needs to be completed for this patient within 10 minutes after hospital arrival?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.
What is the time frame in order for the stroke patient to receive Fibrinolytics?As a result, intra-arterial fibrinolytic therapy is commonly administered as an off-label therapy for stroke at tertiary centers within 6 hours of onset in the anterior circulation and up to 12-24 hours after onset in the posterior circulation.
