Clinical HistoryClinical History
A 911 call was taken by the Chicago Fire Department dispatch service at 2:25 pm. The caller stated, “My husband is having a stroke and he can not move the left side of his body”. An ALS ambulance arrived at 2:34 pm and found the 67-year-old patient to be sitting in a chair with a BP 140/85, pulse 96, respiratory rate 16 and the inability to move his left arm or leg. His wife also noticed the left side of his face was “flat”. He was able to speak and denied headache, chest pain or shortness of breath.

Clinical HistoryClinical History
He had a history of hypertension, was on Labetalol and Lasix, with no allergies. The paramedics noted the time of onset for the symptoms to be 2:15 pm., which was agreed to by both the patient and his wife. The patient was placed on a cart, an IV was established, oxygen was applied, and glucose was 98. The paramedics called into the base station at 2:48 pm, stating, “We have a probable stroke, with two out of three abnormal on the Cincy scale” and arrived in the ED at 2:52 pm.

Key Clinical QuestionsKey Clinical Questions
• Who, What, Why of Stroke Center designation?• Does my hospital need to become a Stroke
Center?• Does a Stroke Team improve ED care of stoke
patients?• Can an ED use thrombolytics if it is not a
Stroke Center?• What is EMS role in the process?• What are the EM controversies in the care of
stroke patients?

Importance of Rapid Identification and TriageImportance of Rapid Identification and Triage
• Intervention in acute ischemic stroke requires the rapid and careful • Assessment• Selection• Treatment • Within 3 hours of symptom onset
• Multiple disciplines and departments• Pre-hospital responders and in-hospital care
providers• Perceptions, attitudes, and behavior of the public
• Warning signs of stroke • Need for rapid and immediate action

Factors Potentially Delaying Factors Potentially Delaying Response Times in StrokeResponse Times in Stroke
• Inadequate public/patient awareness of signs and symptoms and need to call EMS early
• Strokes don’t cause pain• The need for time urgency for emergency

• Modification of existing EMS programs for rapid identification, triage, treatment, and transport of emergency stroke patients

• There is a severe knowledge deficit about stroke that is greater in those at a high risk for stroke, including:• Elderly• Less educated• Persons with low income• Men• Asian Americans
• Knowledge deficit can be improved through community-based education, particularly through public service announcements on television

• Facial Droop (Patient shows teeth or smiles):• Normal (Both sides of face moves equally well)• Abnormal (One side of face doesn’t move as well as other side)
• Arm drift:• Normal (Both arms move the same OR both arms don’t move at all)• Abnormal (One arm either doesn’t move OR one arm drifts down
compared to the other)
• Speech (The patient says “The Cubs aren’t going to the playoffs”):• Normal (Patient says correct words with no slurring of words)• Abnormal (Patient slurs words, says the wrong words, or is unable
to speak)

AHA-Recommended Assessment of a Person AHA-Recommended Assessment of a Person With Suspected Stroke by EMS PersonnelWith Suspected Stroke by EMS Personnel• Assure adequate airway
• Monitor vital signs
• Conduct general medical assessment
• Evidence of trauma to head or neck
• Cardiovascular abnormalities
• Ocular signs
• Conduct neurological examination• Prehospital assessment (eg, Cincinnati Prehospital Stroke Scale)
• Level of consciousness (Glasgow Coma Scale)
• Pupils: size, equality, reactivity
• Presence of seizure activity
• Prearrival notification: estimated time of onset, Glascow Coma Scale score

Assessing the Role of Paramedic Assessing the Role of Paramedic Diagnosis and ED Efficiency Diagnosis and ED Efficiency
• Houston study• Performance data from paramedics and 6 hospital EDs• Data collected from 446 patients with suspected acute
stroke• Data were used to assess the effect of:
• Establishing emergency stroke centers• Paramedic education program
• Target treatment times were based on ASA standards• Unenhanced CT scan of the brain within 30 minutes• Maximum of 60 minutes for initiation of tPA

at the ED within 120 minutes of onset• There were 319 case report forms submitted
with thrombolysis data; 195 of these cases had acute ischemic stroke diagnosed; hospitals 3 and 6 did not administer thrombolytics

arrive in the emergency department within 3 hours
• ASA standards can promote uniform stroke assessment and treatment processes

Recommendations for Stroke Care Recommendations for Stroke Care Following Admission to HospitalFollowing Admission to Hospital
• Admission to a stroke unit with comprehensive rehabilitation for patients
• Frequent neurological status checks and vital signs during the first 24 hours
• Early mobilization and measures to prevent stroke complications• Aspiration, malnutrition, pneumonia, deep vein thrombosis
(DVT), pulmonary embolism, pressure sores, orthopedic complications, and contractures
• Prophylactic treatment to prevent DVT • Treatment of infectious complications with antibiotics• Treatment of concurrent medical conditions

unanimously adopted a resolution to monitor the progress of any federal stroke legislation and dedicate resources to make members of Congress aware that:• Standards of care in stroke treatment remain controversial• The designation of stroke centers based on their ability /
willingness to adhere to such standards of care may have many unintended negative consequences

Clinical CourseClinical Course
The patient was met by a nurse, a doctor and an EM tech and taken to the resuscitation room. They confirmed the onset time of 2:15pm. Vital signs were BP 142/88, P 98, R 16, T 99.2 F. HEENT: eyes were deviated to the right but came back to midline with command, PERRL, Ears clear, neck supple. Heart, lungs and abdomen were normal. Neurological exam: CN mild left facial droop, strength 5/5 R arm and leg, 1/5 L arm and leg, no light touch or pin prick sensation in the L arm and leg. NIHSS=17-18.

Clinical CourseClinical Course• The stroke team was called at 3:05pm • Labs were drawn and sent. • The patient went to CT at 3:20 pm and
returned at 3: 41pm.• The stroke team assessed the patient on
return from CT and agreed with the diagnosis of CVA and NIHSS=18.
• Head CT reading was “negative for bleed, normal brain” at 4:03pm.
E. Bradshaw Bunney, MD, FACEPE. Bradshaw Bunney, MD, FACEP
Clinical CourseClinical Course• The patient was felt to be a good candidate for
thrombolytics. The patient was advised of the risks and benefits.
• The patient, along with his wife refused thrombolytic therapy, stating “I want nature to take its course”.
• The patient was given 325 mg. of aspirin and admitted to the hospital.
• His 24 hour NIHSS=14.• On discharge, 5 days later, NIHSS=10.

Key Learning PointsKey Learning Points• JACHO Stroke Center certification requires
multi-disciplinary cooperation with one central champion
• Strict adherence to stroke protocols improves outcomes in these patients
• EMS plays a KEY role in maximizing the management of stroke patients
• The EM community has numerous concerns about the Stroke Center designation concept
