Stroke in The Prehospital Setting
• Stroke must be suspected quickly by EMTs and paramedics in the field.
• In one study EMTs and Paramedics correctly identified stroke and TIA in 72% of the patients with either condition.
• Extensive neurological exams are impractical in the prehospital setting

CINCINNATI STROKE SCALE
• Identifies patients with strokes.
• It evaluates three major physical findings.– Facial droop– Motor arm weakness– Speech abnormalities

Facial Droop
• Have the patient show their teeth or smile.
• Normal – both sides of the face move equally well
• Abnormal – one side of the face does not move as well as the other side

Arm Drift
• Have the patient close his/her eyes and hold both arms out.
• Normal – both arms move the same way, or both arms do not move at all.
• Abnormal – one arm does not move or one arm drifts down compared to the other arm.
Other findings such as pronater grip, may be helpful

Speech
• Have the patient say “You can’t teach an old dog new tricks.”
• Normal – patient uses correct words with no slurring.
• Abnormal – patient slurs words, uses inappropriate words, or is unable to speak

“You can’t teach an old dog new tricks.”

Cincinnati Prehospital Stroke Scale
• Patients with 1 of these 3 findings -as a new as a new eventevent - have a 72% probability of an ischemic stroke.
• If all 3 findings are present the probability of an acute stroke is more than 85%
• Immediately contact medical control and the destination ED and provide prearrival notification.

Stroke
• Once the diagnosis of stroke is suspected, time in the field must be minimized.time in the field must be minimized.
• The presence of a patient with acute stroke is a “load and go”.load and go”.
• A more extensive examination or initiation of supportive therapies should be accomplished en route to the hospital.

Stroke
• One of the most important aspects of your history must be the time of onset of the symptoms.
• This time will have important implications for potential therapy.
• Early notification of the ED is essential.• Careful assessment is a must, signs of
stroke can be very subtle.

Evaluation
• Describe the importance of rapid detection CVA/TIA symptoms in the prehospital setting.
• Describe why extensive neurological examinations are inappropriate in the prehospital setting.

Evaluation
• Describe the three points evaluated in the Cincinnati Stroke Scale evaluation.
• Perform a Cincinnati Stroke Scale evaluation on a victim

Summary
Early detection of CVA/TIA in the prehospital setting can have a dramatic effect of the mortality and morbidity of patients. In depth neurological exams are not only un-necessary in the prehospital settings but are in fact counter productive. Using the Cincinnati Stroke Scale an EMT or Paramedic can quickly and accurately access the neurological status of a patient presenting with CVA/TIA Signs and symptoms.
