There are two known variations of a stroke: ischemic and hemorrhagic. In the case of ischemic stroke, a clot forms in one of the
brain’s blood vessels, blocking the flow through the vessel. In a hemorrhagic stroke, a blood vessel in the brain erupts and spews out blood into the brain tissue. Ischemic and hemorrhagic stroke account for 87% and 13% of total incidents, respectively. Generally, the symptoms of both types of strokes are similar. It is the treatments that are different from each other. • 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 Within 10 minutes of arrival, a collective team of physicians and other experts should immediately assess the patient with suspected stroke at the emergency department (ED). The region of the brain that is affected by the stroke determines the clinical signs, due to the decreased or blocked blood flow in certain areas. Certain symptoms may include having difficulty walking and with balance; a loss of vision; slurred and broken speech; facial droop; severe change of consciousness; headaches and vomiting; and numbness or weakness in the leg, arm, or face. The symptoms that may show depend entirely on the affected cerebral artery; not all symptoms may be found to be present. In diagnosing whether or not a stroke is present in a patient, the Cincinnati Prehospital Stroke Scale (CPSS) is used if certain physical findings are seen, such as broken and abnormal speech, arm drift, or facial droop. There is a 72% probability of an ischemic stroke present in a patient that is displaying even one of these three findings. The probability of an acute stroke rises to more than 85% if all three findings are observed. It is recommended to become proficient with the tool, FAST, used by the rescuers’ EMS system. The usage and training of these screening tools can be facilitated by practice and mock scenarios. 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 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 test should the patient receive within 25 minutes of hospital arrival?The CT scan should be completed within 25 minutes from the patient's arrival in the ED and should be read within 45 minutes. Within 45 minutes of the patient's arrival, the specialist must decide, based on the CT scan or MRI, if a hemorrhage is present.
What additional assessment and stabilization activities should be completed within the first 10 minutes after the patient's arrival ACLS?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.
What time specific goal should occur within 10 minutes of a stroke patients arrival to the ED?The goal of the stroke team, emergency physician, or other experts should be to assess the individual with suspected stroke within 10 minutes of arrival in the emergency department (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.
