What to Do During a Severe Hypoglycemia Event: A Step-by-Step Guide

Severe hypoglycemia, or severely low blood sugar, is a dangerous condition that can occur in individuals with diabetes, particularly those taking insulin or certain oral medications. Recognizing and promptly treating severe hypoglycemia is crucial to prevent serious complications, including seizures, loss of consciousness, and even death. This comprehensive guide provides a step-by-step approach to handling a severe hypoglycemic event effectively. Understanding the signs, having a plan, and acting swiftly can make a life-saving difference.

Understanding Severe Hypoglycemia

Hypoglycemia occurs when the level of glucose (sugar) in the blood drops too low. While mild hypoglycemia can often be managed with simple carbohydrate intake, severe hypoglycemia is defined as a situation where the individual requires assistance from another person to administer treatment because they are unable to do so themselves due to confusion, unresponsiveness, or loss of consciousness.

Key Indicators of Severe Hypoglycemia: - Inability to follow instructions - Confusion or disorientation - Loss of consciousness - Seizures

Recognizing these signs quickly is the first step in effective management. A delay in treatment can lead to serious consequences.


Step-by-Step Guide to Responding to a Severe Hypoglycemic Event

When someone experiences a severe hypoglycemic event, the following steps should be taken immediately and methodically:

1. Assess the Situation:

First, verify that the person is indeed experiencing severe hypoglycemia. If the individual is conscious but confused or unable to follow instructions, it is reasonable to suspect low blood sugar. If they are unconscious, proceed immediately with emergency treatment, assuming hypoglycemia is the likely cause, especially if the individual has a history of diabetes.

  • Action: Check for a medical ID bracelet or necklace indicating diabetes.
  • Note: If there’s any doubt, treat for hypoglycemia, as it's safer to raise blood sugar slightly than to ignore a potentially life-threatening situation.

2. Administer Glucagon (If Available):

Glucagon is a hormone that raises blood sugar levels quickly. It is typically prescribed to individuals at risk of severe hypoglycemia, and their caregivers or family members should be trained on how to administer it.

  • Glucagon Administration Steps:
    1. Locate the glucagon emergency kit.
    2. Follow the instructions provided in the kit. Typically, this involves mixing the glucagon powder with the diluent (liquid) in the syringe.
    3. Inject the glucagon into the person’s thigh, upper arm, or buttock. The injection can be given through clothing if necessary.
    4. Once the injection is given, note the time.

| Glucagon Delivery Method | Onset of Action | Duration of Effect | Considerations | | :---------------------- | :----------------- | :----------------- | :--------------------------------------------------------- | | Intramuscular Injection | 10-15 minutes | 60-90 minutes | Standard method, requires mixing and injection | | Intranasal Glucagon | 10-15 minutes | 60-90 minutes | Newer method, user-friendly, no mixing or injection needed |

3. Call for Emergency Medical Assistance:

Even if glucagon is administered and the person regains consciousness, it’s crucial to call emergency services (such as 911 in the United States) immediately. Severe hypoglycemia can sometimes be a sign of an underlying issue, and professional medical evaluation is necessary.

  • Why call emergency services?
    • To ensure comprehensive medical assessment and treatment.
    • To prevent recurrence of hypoglycemia, especially if the cause is unknown.
    • For continuous monitoring until the individual is stable.

4. Monitor the Person’s Condition:

After administering glucagon and calling for emergency help, continue to monitor the person’s condition closely. Note any changes in their level of consciousness, breathing, and skin color.

  • Key monitoring points:
    • Check for improvement in alertness.
    • Observe breathing for any difficulties.
    • Look for changes in skin color (e.g., becoming less pale or sweaty).

5. Provide Oral Carbohydrates (If Conscious and Able to Swallow):

If the person regains consciousness and is able to swallow, give them a fast-acting source of carbohydrates to help stabilize their blood sugar levels. Examples include:

  • Fast-Acting Carbohydrate Options:
    • Fruit juice (4 ounces or 120 milliliters)
    • Regular soda (not diet)
    • Glucose tablets or gel (follow package instructions)
    • Honey or sugar (1 tablespoon)

Example: After giving the glucagon injection, Sarah slowly regains consciousness after about 10 minutes. Once she is alert enough to follow simple instructions, her friend gives her 4 ounces of apple juice to drink.

6. Prevent Aspiration (If There is Vomiting):

If the person vomits, turn them on their side to prevent aspiration into the lungs, which can cause serious complications.

  • Preventing Aspiration:
    • Gently roll the person onto their side.
    • Ensure their airway remains clear.
    • Monitor breathing closely.

7. Document the Event:

Documenting the details of the hypoglycemic event, including the time it occurred, the interventions taken, and the person’s response, can be valuable for medical professionals.

  • Document Key Information:
    • Time of the event
    • Signs and symptoms observed
    • Interventions given (e.g., glucagon administration)
    • The person's response to treatment

Essential Preparations for Hypoglycemia

1. Diabetes Education:

Ensure that individuals with diabetes and their caregivers receive comprehensive education on hypoglycemia, including its causes, symptoms, treatment, and prevention.

2. Medical Identification:

Individuals with diabetes should wear a medical ID bracelet or necklace that clearly indicates their condition. This can alert first responders to the possibility of hypoglycemia in case of an emergency.

3. Glucagon Kit:

Always have a glucagon emergency kit readily available at home, work, and when traveling. Ensure that family members, friends, and colleagues know where it is located and how to use it. Check the expiration date regularly and replace it as needed.

4. Blood Glucose Monitoring:

Regularly monitor blood glucose levels, especially before meals, before bedtime, and after exercise. Understanding blood sugar patterns can help prevent severe hypoglycemia.

5. Meal Planning and Timing:

Adhere to a consistent meal schedule and avoid skipping meals, as this can lead to low blood sugar. Work with a registered dietitian or certified diabetes educator to develop an appropriate meal plan.

| Action | Justification | | :-------------------------------- | :----------------------------------------------------------------------------------------- | | Regular Glucose Monitoring | Identifies trends and patterns to proactively manage glucose levels. | | Consistent Meal Timing | Prevents drastic drops in blood sugar levels by ensuring a steady glucose supply. | | Carrying Fast-Acting Carbohydrates | Provides immediate treatment for mild to moderate hypoglycemia. | | Having Glucagon Available | Acts as an emergency intervention for severe hypoglycemia when the person is unable to eat. | | Educating Family and Friends | Ensures timely assistance and proper glucagon administration when needed. |


What NOT to Do During a Severe Hypoglycemic Event

1. Do Not Give Oral Food or Liquids to an Unconscious Person:

Giving food or liquids to an unconscious person can lead to choking or aspiration pneumonia, which can be life-threatening.

2. Do Not Inject Insulin:

Never administer insulin to a person experiencing hypoglycemia, as this will further lower their blood sugar levels and exacerbate the condition.

3. Do Not Panic:

Remaining calm and acting methodically is essential for providing effective assistance. Panic can lead to mistakes and delays in treatment.
