What to Do During a Severe Hypoglycemia Emergency: A Step-by-Step Plan

Severe hypoglycemia, also known as low blood sugar, can be a frightening and dangerous condition, particularly for individuals managing diabetes. It occurs when the glucose level in the blood drops to a point where the brain doesn't have enough fuel to function correctly. Recognizing the signs and having a well-defined action plan is crucial for ensuring the safety of yourself or someone you know. This guide provides a detailed, step-by-step approach to handling a severe hypoglycemia emergency.

Understanding Severe Hypoglycemia: Severe hypoglycemia generally means that blood sugar levels are so low that the individual is unable to treat themselves. This often leads to symptoms such as confusion, loss of consciousness, seizures, or coma. It's crucial to know the symptoms and be prepared to act quickly.

Why a Step-by-Step Plan Matters

Having a structured plan ensures that you remain calm and take the necessary actions without delay. The prompt administration of glucose or glucagon can be life-saving in such situations. Let's break down the steps.


Step 1: Recognize the Signs and Symptoms

The first step in addressing a severe hypoglycemia emergency is recognizing the signs and symptoms. While milder forms of hypoglycemia can cause symptoms such as shakiness, sweating, and anxiety, severe hypoglycemia presents more alarming symptoms.

Common Symptoms of Severe Hypoglycemia:

  • Confusion or disorientation: The person may seem confused, unable to follow instructions, or have difficulty speaking.
  • Loss of consciousness: This is a critical sign indicating the need for immediate intervention.
  • Seizures: Uncontrolled muscle contractions, indicating severe neurological distress.
  • Unusual behavior: Erratic or aggressive actions that are out of character.
  • Inability to eat or drink: The person may be unable to swallow or cooperate with attempts to provide sugar orally.

Importance of Differentiation: It’s essential to distinguish these symptoms from other medical conditions. However, if you know the person has diabetes and exhibits these symptoms, it’s safer to assume it's hypoglycemia and act accordingly.


Step 2: Assess the Situation and Ensure Safety

Once you recognize the symptoms, quickly assess the situation to ensure both the affected individual's and your own safety.

Key Considerations:

  1. Environment: Is the person in a safe location? If they are in a dangerous environment (e.g., near traffic, in water), move them to a safer place immediately.
  2. Breathing: Check if the person is breathing. If they are not breathing, initiate CPR (Cardiopulmonary Resuscitation) if you are trained to do so, and call emergency services (e.g., 911) immediately.
  3. Medical ID: Look for a medical ID bracelet or necklace indicating that the person has diabetes. This can provide crucial information for first responders.

Example Scenario: Imagine you're at a park, and a person you know with diabetes suddenly collapses and appears confused. First, move them away from any potential hazards like a nearby pond. Then, check their breathing and look for a medical ID.


Step 3: Administer Glucagon (If Available and Trained)

Glucagon is a hormone that stimulates the liver to release stored glucose into the bloodstream, raising blood sugar levels. It is typically prescribed to individuals at risk of severe hypoglycemia. If glucagon is available and you are trained to administer it, follow these steps:

How to Administer Glucagon:

  1. Locate the Glucagon Kit: Glucagon kits typically contain a syringe with sterile water and a vial of powdered glucagon.
  2. Prepare the Injection: Mix the sterile water with the powdered glucagon by injecting the water into the vial and gently rolling the vial to dissolve the glucagon.
  3. Administer the Injection: Inject the glucagon into the person’s thigh, arm, or buttock muscle, as per the instructions in the kit. You can administer the injection through clothing if necessary.
  4. Dosage: Administer the entire dose, which is typically 1 mg for adults and children over 25 kg (55 lbs), and 0.5 mg for children under 25 kg (55 lbs). Always follow the specific instructions provided with the glucagon kit.
  5. Timing: Note the time of the injection. It may take 10-15 minutes for the person to regain consciousness.

Table: Glucagon Dosage Guidelines

| Age/Weight | Dosage | | -------------------------- | ---------------- | | Adults and Children > 25kg | 1 mg | | Children < 25kg | 0.5 mg |

Important Considerations:

  • Training: Only administer glucagon if you have been trained by a healthcare professional on how to use it.
  • Expiration Date: Check the expiration date on the glucagon kit. Expired glucagon may not be effective.
  • Positioning: After administering glucagon, turn the person onto their side to prevent choking in case they vomit.

Step 4: Call for Emergency Medical Assistance

Regardless of whether you administer glucagon, call emergency services (e.g., 911) immediately. Even if the person regains consciousness after glucagon administration, professional medical evaluation is crucial to determine the underlying cause of the hypoglycemia and prevent recurrence.

Information to Provide to Emergency Services:

  • That the person has diabetes.
  • That they are experiencing severe hypoglycemia.
  • The symptoms they are exhibiting.
  • Whether glucagon was administered and the time it was given.
  • The person’s location.

Why Calling Emergency Services is Critical:

  • Professional Evaluation: Emergency medical personnel can assess the person's overall condition and provide further treatment as necessary.
  • Monitoring: They can monitor vital signs and blood glucose levels to ensure stability.
  • Transportation: They can transport the person to a hospital for further evaluation and treatment if needed.

Step 5: If Conscious and Able to Swallow, Provide Fast-Acting Sugar

If the person regains consciousness and is able to swallow, provide a source of fast-acting sugar to help raise their blood glucose levels quickly.

Suitable Sources of Fast-Acting Sugar:

  • Glucose Tablets: These are specifically designed to raise blood sugar levels rapidly. Follow the package instructions for dosage.
  • Juice: Fruit juice (e.g., orange juice, apple juice) can provide a quick source of glucose.
  • Regular Soda: Non-diet soda contains sugar that can be rapidly absorbed.
  • Honey or Corn Syrup: A tablespoon of honey or corn syrup can be placed under the tongue for quick absorption.
  • Hard Candies: If other options aren't available, hard candies that can be chewed and swallowed can help.

Dosage and Monitoring:

  • Give approximately 15-20 grams of fast-acting carbohydrates.
  • Check blood glucose levels again after 15 minutes. If blood sugar is still low (typically below 70 mg/dL), repeat the process with another 15-20 grams of fast-acting carbohydrates.

Follow-Up: Once blood glucose levels have risen above 70 mg/dL and the person is stable, provide a snack containing both carbohydrates and protein (e.g., crackers with peanut butter) to help stabilize blood sugar levels and prevent a recurrence of hypoglycemia.


Step 6: Monitor and Document the Event

Even after initial treatment, continue to monitor the person’s condition until emergency services arrive or they are fully recovered. Document the event, including the time of the hypoglycemia, the symptoms observed, the interventions provided (e.g., glucagon administration, fast-acting sugar), and the person’s response to treatment.

Importance of Documentation:

  • Medical History: This information can be valuable for healthcare providers in understanding the person’s diabetes management and adjusting treatment plans as necessary.
  • Identifying Patterns: Documenting the event can help identify patterns or triggers that may have contributed to the hypoglycemia, allowing for preventative measures to be taken in the future.

What to Document:

  • Time of Event: When the hypoglycemia was first noticed.
  • Symptoms: Specific symptoms observed.
  • Blood Glucose Levels: If available, record the blood glucose readings.
  • Interventions: What actions were taken (e.g., glucagon, sugar).
  • Response: How the person responded to the interventions.
  • Follow-Up: What happened after (e.g., emergency services called, transported to hospital).

Preventing Future Episodes

After a severe hypoglycemic event, it's crucial to take steps to prevent future episodes.

Strategies for Prevention:

  • Diabetes Education: Ensure the person and their caregivers receive comprehensive diabetes education, including information on blood glucose monitoring, insulin administration, meal planning, and recognizing and treating hypoglycemia.
  • Regular Blood Glucose Monitoring: Encourage frequent blood glucose monitoring to identify and address low blood sugar levels early.
  • Medication Management: Work with a healthcare provider to optimize medication dosages and timing to minimize the risk of hypoglycemia.
  • Meal Planning: Follow a consistent meal plan with regular meals and snacks to maintain stable blood glucose levels.
  • Emergency Kit: Always carry a glucagon kit and fast-acting sugar, and ensure that family members, friends, and caregivers know how to use them.
  • Medical ID: Wear a medical ID bracelet or necklace to alert others to the fact that they have diabetes.
