Normal: No preferred gaze and eyes move past midline upon request.

**Patient has signs & symptoms consistent with stroke or T.I.A.
**LAST TIME SEEN NORMAL is < 3.5 hours and patient does not meet criteria for intra-arterial therapy
* If IV is obtained, it should be at least an 18 gauge.  Avoid multiple attempts and IO's

VAN Assessment

Visual IS VISION GAZED IN ONE DIRECTION? NEW ONSET BLINDNESS?

Test: Ask the person to look up, then down then left, then right. Or have them follow your finger in those directions.

Normal: No preferred gaze and eyes move past midline upon request.

Abnormal: Gaze is deviated to one side and does not pass the midline upon request or new onset blindness.

Aphasia CAN THE PERSON SPEAK & UNDERSTAND LANGUAGE?

Test: Ask them to name an ordinary object such as a pen. Or ask them to make a fist

Normal: The patient can understand language and name ordinary objects.

Abnormal: Inability to understand or express speech or name ordinary objects, does not follow simple commands such as “close your eyes” or make a fist

Slurred speech alone does not indicate a positive VAN test

Neglect IS THE PATIENT IGNORING ONE SIDEOF THE BODY (Usually the left side)?

Test: Ask the patient to close their eyes and tell them that you will touch each arm individually and then both at the same time. Ask them to acknowledge each touch.

Normal: Patient acknowledges both individual touches and simultaneous touch.

Abnormal: Patient does not acknowledge simultaneous touch usually ignoring the left side

If the patient does not acknowledge individual touches this does not indicate a positive VAN test.


ARM DRIFT PLUS ONE OF THE ABOVE IS VAN POSITIVE

BE-FAST and VAN assessments often are performed simultaneously

TRANSPORT DESTINATION (Determined ONLY by VAN Assessment Results)

If patient exhibits symptoms, regardless of time frame, call in as STROKE ALERT

Stroke receiving center can determine acuity and level of aggressive action.

Transporting EMERGENCY or NON-EMERGENCY is determined by the crew but a LKW of <24 should receive EMERGENCY transportation.

Use of air medical resources is appropriate when the window for evaluation for Intra-arterial therapy is less than 1-hour and ground transport exceeds 30 minutes.


DESTINATION SELECTION
All suspected stroke and TIA patients must be transported to a stroke-receiving facility, unless the patient is UNSTABLE.
VAN Negative PRIMARY STROKE CENTER
VAN Positive COMPREHENSIVE STROKE CENTER
Suspected Cerebellar infarct with posterior circulation LVO symptoms COMPREHENSIVE STROKE CENTER
VAN NEGATIVE or POSITIVE and tPA EXCLUSIONS COMPREHENSIVE STROKE CENTER


COMPREHENSIVE STROKE DESTINATIONS
  • Evaluation of suspected Large Vessel Occlusion (LVO) -or-
  • Suspected Cerebellar infarct with posterior circulation LVO symptoms, including acute dizziness/balance findings or acute visual changes (blurred, limited or double vision)
  • Have contraindications for IV therapy such as Coumadin therapy, recent surgery, treatment of bleeding ulcer, etc.
