Why Do You Put Someone on Their Left Side During a Seizure? Understanding the Recovery Position

When witnessing a seizure, your first instinct might be to help the person having it. One of the most crucial steps you can take after the convulsive phase of a seizure has passed is to place the individual on their left side. This seemingly simple action, known as the recovery position, plays a vital role in ensuring their safety and well-being. But why specifically the left side? Let's delve into the reasons behind this important first-aid practice.

The Dangers During and Immediately After a Seizure

During a seizure, a person experiences uncontrolled electrical activity in the brain, leading to involuntary muscle contractions, altered consciousness, and other symptoms. While the convulsive phase is often the most dramatic, the period immediately following the seizure, known as the postictal phase, also carries risks.

Aspiration: One of the primary concerns is aspiration, which is when foreign matter, such as vomit or saliva, is inhaled into the lungs. During and after a seizure, muscles can become relaxed, and the person may lose control of their gag reflex. If they are lying on their back, their tongue can fall back into their throat, potentially blocking the airway and increasing the risk of vomit entering the lungs.
Tongue Swallowing: As mentioned, the tongue can naturally relax backward during unconsciousness or semi-consciousness. If the person is on their back, this can obstruct breathing.
Choking: Excessive saliva or mucus can build up in the mouth and throat, leading to choking if the person cannot clear their airway.

The Science Behind the Left-Side Recovery Position

Placing someone on their left side specifically addresses these risks. Here's a breakdown of why the left side is preferred:

1. Gravity and Airway Management

When a person is positioned on their left side, gravity helps to keep their tongue from falling back and obstructing their airway. The airway remains open, allowing for easier breathing.

2. Drainage of Fluids

The left side position facilitates the drainage of saliva, mucus, and any potential vomit away from the airway and out of the mouth. This significantly reduces the risk of aspiration into the lungs. Think of it as allowing the body to naturally clear itself.

3. Preventing Accidental Ingestion

If the person were to vomit while lying on their back, the vomit could easily be inhaled into their lungs. The left-side recovery position directs any expelled fluids downwards and out, minimizing this dangerous possibility.

4. Comfort and Blood Flow (Secondary Benefits)

While airway protection is the primary reason, the left-side position is also generally considered more comfortable for recovery. Some theories suggest that it can also aid in better blood flow to the brain and vital organs compared to the right side, although airway safety remains the paramount concern.

How to Place Someone in the Recovery Position

It's essential to know how to properly place someone in the recovery position. Remember to only do this after the active seizure has stopped and the person is no longer convulsing. The person may be unconscious or very drowsy.

Ensure Safety: First, ensure the person is in a safe place, away from any potential hazards. Loosen any tight clothing around their neck.
Kneel Beside Them: Kneel by the person's side.
Straighten Their Legs: Make sure both their legs are straight.
Bring the Far Arm Up: Take the arm furthest from you and bend it at the elbow, placing their hand on the side of their head closest to you.
Bring the Near Leg Up: Take the leg closest to you and bend it at the knee, so their foot is flat on the surface.
Roll Them Over: Gently roll the person onto their side, towards you. Use their bent knee to support their position.
Adjust the Top Leg: Ensure their top leg is bent at the hip and knee to keep them stable.
Open the Airway: Tilt their head back slightly and lift their chin to ensure their airway remains open.
Check for Breathing: Continuously monitor their breathing until medical help arrives.

When to Seek Medical Attention

Even if the seizure appears to stop on its own and you've placed the person in the recovery position, it is crucial to always call 911 immediately after a seizure. Medical professionals need to assess the person to determine the cause of the seizure, check for any injuries, and ensure they are recovering properly.

What NOT to Do During a Seizure

It's equally important to know what not to do. Never:

Restrain the person.
Put anything in their mouth.
Try to wake them up forcefully.
Give them food or drink until they are fully alert.

By understanding the importance of the left-side recovery position and knowing how to administer it, you can significantly contribute to the safety and well-being of someone experiencing a seizure. This knowledge empowers you to act effectively and confidently in a critical situation.

Frequently Asked Questions (FAQ)

Q: Why is the left side preferred over the right side for the recovery position during a seizure?

A: The left side is preferred primarily to facilitate the drainage of fluids like saliva and vomit away from the airway due to the positioning of internal organs and the natural slope created by gravity. This significantly reduces the risk of aspiration, a dangerous condition where foreign matter enters the lungs.

Q: How long should someone remain in the recovery position after a seizure?

A: A person should remain in the recovery position until they are fully conscious and able to maintain their own airway. However, it is crucial to call 911 immediately after any seizure, and medical professionals will determine when it is safe to move the individual from the recovery position.

Q: What if the person vomits while in the recovery position?

A: If the person vomits while in the recovery position, gravity and the side-lying posture will help to direct the vomit out of their mouth and away from their airway. Continue to monitor their breathing and keep their airway open by tilting their head back slightly and lifting their chin.
