“Time is brain.” You’ve heard it a thousand times, but when you’re staring at a patient with facial droop, the pressure is real. Every minute you delay, the brain loses millions of neurons. As an EMT, your ability to rapidly assess and decide where to transport a stroke patient can be the difference between recovery and permanent disability. It’s not just about driving fast; it’s about driving smart. In this guide, we’ll walk through the essential steps to manage a stroke alert efficiently, ensuring your patient gets the life-saving intervention they need.
Step 1: Confirming the Stroke (Brief Review)
Before you worry about the destination, you need to be sure you’re dealing with a stroke. While your gut feeling is usually right, we rely on tools to be accurate. You are likely familiar with the Cincinnati Prehospital Stroke Scale (CPSS) or the FAST exam.
Think of the CPSS as your quick “rule-out” tool. You are checking for three specific things:
- Facial Droop: Ask them to smile. Does one side drift downward?
- Arm Drift: Have them close their eyes and hold both arms out. Does one arm drift down slowly?
- Speech: Ask them to say a simple phrase like “The sky is blue.” Is it slurred or are they using the wrong words?
Clinical Pearl: Remember, hypoglycemia (low blood sugar) is the great “stroke mimic.” Always check a fingerstick glucose. If the blood sugar is low, treat the hypoglycemia first—the “stroke” might disappear instantly.
Step 2: Determining the Destination
This is where the “Decision Dilemma” kicks in. You are 10 minutes from a local community hospital and 25 minutes from a Comprehensive Stroke Center. Your instinct might be to go to the closest place, but for stroke, that instinct is often wrong.
Research consistently shows that specialized centers have better outcomes for ischemic strokes. You need to activate your Code Stroke Protocol.
Mother Ship vs. Drip and Ship
Your medical direction will usually dictate one of two strategies:
- Mother Ship: Bypass the local hospital and go straight to the Stroke Center for immediate imaging and potential intervention (like tPA or thrombectomy).
- Drip and Ship: Go to the local hospital to administer tPA, then transfer to the Stroke Center.
Unless transport time to the Stroke Center is excessive (usually over an hour or more), protocols generally favor “Mother Ship” for severe cases.
Choosing the Right Hospital
| Facility Type | Capabilities | Best For… |
|---|---|---|
| Local ER (Non-Stroke) | Stabilization, basic CT | Patients who are unstable or if transport time to a Stroke Center is > 60-90 mins. |
| Primary Stroke Center (PSC) | Can administer tPA (clot-buster) | Most standard ischemic strokes within the tPA window. |
| Comprehensive Stroke Center (CSC) | tPA + Mechanical Thrombectomy | Large Vessel Occlusions (LVO) – severe strokes needing physical clot removal. |
| Winner/Best For | Comprehensive Stroke Center | Suspected LVO or large deficits (total paralysis, neglect). |
Pro Tip: When in doubt, contact medical control immediately. Be prepared to give them the patient’s age, time of onset, and severity of symptoms (e.g., “He has a dense hemiplegis”). They make the final call, but your accurate report drives that decision.
Step 3: Scene Management & Packaging
You’ve confirmed the stroke and chosen the destination. Now, get moving. Minimizing on-scene time is critical.
The 15-Minute Rule: Aim for a “door-to-needle” time of under 15 minutes at the hospital, which starts with you keeping your scene time short.
Don’t wait for the family to gather or the neighbor to arrive. Get the patient loaded.
Positioning the Patient
How do you position a stroke patient in the ambulance?
- Position: Supine with the head of the stretcher elevated to about 30 degrees, unless the patient is hypotensive.
- Rationale: Elevating the head helps lower intracranial pressure and encourages venous drainage from the brain. It can also help protect the airway if the patient has a decreased gag reflex.
Pro Tip: “While you are grabbing the stretcher, ask a family member to grab the patient’s medication bottles.” You don’t need to read every label right now, but having them in the bus saves the hospital staff critical time later.
Step 4: In-Transit Care & Monitoring
Once the wheels are turning, your job shifts to stabilization and reassurance.
Vital Signs: Monitor BP, Pulse Ox, and Respirations every 5 minutes.
Blood Pressure: Here is a critical rule—do not lower the blood pressure in the field.
Common Mistake: Treating hypertension in a suspected stroke patient.
Why it’s a mistake: The brain is trying to perfuse itself through blocked vessels. Lowering the BP can cause the area of the stroke (the penumbra) to die. Unless the BP is dangerously high (usually >220/120, though protocols vary) or the patient is actively having a heart attack, keep your hands off the BP meds.
Airway Management: Stroke patients often have difficulty swallowing (dysphagia). Keep them NPO (nothing by mouth). Have suction ready. Vomiting and aspiration are major risks, especially if they have a gag reflex deficit.
Step 5: Pre-Notification & Handoff
Pre-notification is the single most effective intervention you can perform to reduce hospital treatment times. A simple radio report gives the stroke team time to warm up the CT scanner and draw medications before you even hit the bay.
The Elements of a Stroke Report:
- Age and Gender
- Chief Complaint: “Suspected acute stroke.”
- Time Last Known Well: This is the most important data point.
- Cincinnati Score: “Positive for facial droop, arm drift, and speech.”
- Blood Glucose: State that you ruled out hypoglycemia.
The “Time Last Known Well” Documentation
When you finally sit down to write the PCR, the “Time Last Known Well” (LKW) is the anchor of the entire medical record. It determines if the patient is eligible for fibrinolytic therapy.
Do not document “Time Patient Found.” That is different. LKW is the exact moment the patient was last seen at their baseline.
Imagine this: You find a patient on the floor at 0800. They live alone. The neighbor saw them walking the dog at 0600.
- Wrong: 0800 (Time of EMS arrival/found).
- Right: 0600 (Time Last Known Well).
Clinical Pearl: If the patient wakes up from sleep with symptoms, the LKW is the last time they were seen awake and normal—usually when they went to bed the night before.
Conclusion
Transporting a stroke patient isn’t just a ride; it’s a race against biology. By mastering destination criteria, minimizing scene time, and securing an accurate “Time Last Known Well,” you become the most critical link in the chain of survival. Trust your assessment, follow your protocols, and drive with purpose. You’ve got this.
