Severe Hypoglycemia: An Emergency Action Plan for Persons with Diabetes

Hypoglycemia, commonly known as low blood sugar, is a frequent and potentially dangerous complication for individuals with diabetes. While mild to moderate hypoglycemia can often be managed with self-treatment, severe hypoglycemia represents a medical emergency. This condition, characterized by such significant cognitive impairment that the individual requires assistance from another person, demands swift and effective intervention. This article outlines an emergency action plan to guide people with diabetes, their families, and caregivers on how to respond to a severe hypoglycemic episode, ensuring the best possible outcome.

Severe hypoglycemia is defined by a blood glucose level that is so low that the individual cannot treat themselves. They may be confused, disoriented, unconscious, or experiencing seizures. This level of impairment necessitates intervention by another person.

Here’s why immediate action is critical:

  • Brain Function: The brain relies on glucose as its primary energy source. Prolonged or severe hypoglycemia can lead to brain damage, cognitive impairment, and even death.
  • Risk of Accidents: Hypoglycemia can cause impaired judgment, dizziness, and loss of coordination, increasing the risk of falls, accidents, and injuries.
  • Cardiac Risks: Severe hypoglycemia can trigger cardiac arrhythmias (irregular heartbeats), particularly in individuals with pre-existing heart conditions.
  • Recovery Complications: The longer the period of severe hypoglycemia, the longer it takes for the person to recover fully.

Key Indicators of Severe Hypoglycemia

| Symptom Category | Specific Symptoms | | :------------------ | :--------------------------------------------- | | Neurological | Confusion, disorientation, seizures, unconsciousness, difficulty speaking, slurred speech | | Physical | Loss of coordination, weakness, sweating, trembling, palpitations | | Behavioral | Irritability, combativeness, unusual behavior |

Creating a proactive and personalized emergency action plan is paramount for every person with diabetes who is at risk of hypoglycemia. The plan should be developed in consultation with their healthcare provider and shared with family members, caregivers, friends, and colleagues. Here’s a step-by-step approach to creating such a plan:

  1. Identify At-Risk Individuals: Discuss with your doctor your risk for hypoglycemia. Factors contributing to increased risk include:
    • Intensive insulin therapy
    • History of frequent or severe hypoglycemia
    • Hypoglycemia unawareness (not recognizing the early warning signs)
    • Cognitive impairment or dementia
    • Kidney or liver disease
  2. Assemble an Emergency Kit: Prepare a readily accessible emergency kit that includes the following:
    • Glucagon: A prescription medication (available as an injection or nasal spray) specifically designed to raise blood glucose levels quickly. Make sure it is not expired.
    • Fast-Acting Carbohydrate Source: Such as glucose tablets, glucose gel, juice boxes (with 15 grams of carbohydrate) or regular (non-diet) soda. These are crucial if the person is conscious and able to swallow safely.
    • Blood Glucose Meter and Strips: To confirm hypoglycemia and monitor the individual’s response to treatment (if possible).
    • Emergency Contact Information: Include names and phone numbers of family members, doctors, and emergency services.
  3. Educate Family and Caregivers: Ensure that family members, caregivers, and close contacts are thoroughly educated about:
    • Recognizing the signs and symptoms of severe hypoglycemia.
    • Knowing when and how to administer glucagon.
    • Understanding how to safely provide fast-acting carbohydrates (if the person is conscious).
    • Knowing when to call for emergency medical assistance (911).
  4. Wear Medical Identification: Advise the individual with diabetes to wear a medical ID bracelet or necklace clearly stating that they have diabetes and may experience hypoglycemia. This provides crucial information to first responders in case of an emergency.
  5. Practice and Review: Regularly review and practice the emergency action plan with family and caregivers to ensure everyone is comfortable and confident in their roles. Check expiration dates of medications and supplies in the kit.

Step-by-Step Guide to Responding to Severe Hypoglycemia

When faced with a situation where a person with diabetes exhibits signs of severe hypoglycemia, follow these steps:

  1. Assess the Situation: Quickly evaluate the person's condition. Are they conscious? Can they swallow? Are they having seizures?
  2. If Conscious and Able to Swallow:
    • Check blood glucose if possible. If you can't check, assume it is low.
    • Administer a fast-acting carbohydrate source (15-20 grams of carbohydrates). Examples:
      • 3-4 Glucose tablets.
      • 1 tube of glucose gel.
      • 4-6 ounces of regular (non-diet) juice or soda.
    • Recheck blood glucose after 15 minutes. If still low (below 70 mg/dL) or if the person's condition has not improved, repeat the carbohydrate administration.
    • Once blood glucose is above 70mg/dL and the person is feeling better, provide a longer-acting source of carbohydrate and protein, such as crackers with peanut butter or cheese.
  3. If Unconscious or Unable to Swallow:
    • Administer Glucagon: Prepare and administer glucagon according to the package instructions. For the glucagon injection, this typically involves mixing the powdered glucagon with the provided diluent and injecting it into the thigh, arm, or buttock. Nasal glucagon is administered by spraying into one nostril. Important Note: Do not attempt to give food or liquid to an unconscious person, as this poses a choking hazard.
    • Call Emergency Services (911): Immediately call for emergency medical assistance. Clearly state that the person is unconscious or having a seizure due to low blood sugar and that glucagon has been administered. Provide the person's location and any other relevant information.
    • Position the Person Safely: If the person is unconscious, place them in the recovery position (on their side) to prevent choking should they vomit.
    • Monitor Breathing: Ensure the person is breathing adequately. If breathing stops, begin CPR if you are trained to do so.
    • Stay with the Person: Remain with the person until emergency medical personnel arrive.
  4. Post-Event Care:
    • Seek Medical Evaluation: Even after the person has regained consciousness and their blood sugar has returned to normal, it's essential to seek medical evaluation to identify the cause of the severe hypoglycemic episode and adjust the diabetes management plan accordingly.
    • Review the Incident: Carefully review the circumstances leading up to the severe hypoglycemic event to identify potential triggers and prevent future occurrences. Consider factors such as medication dosages, meal timing, physical activity, and illness.
    • Adjust Management Plan: Work with the healthcare team to adjust the diabetes management plan as needed, which may include changes to medication dosages, meal plans, or exercise routines.

Glucagon: A Lifesaving Medication

Glucagon is a hormone that raises blood glucose levels by stimulating the liver to release stored glucose into the bloodstream. It is a critical medication for treating severe hypoglycemia, particularly when the person is unable to take oral carbohydrates.

Types of Glucagon:

| Type of Glucagon | Administration | Key Features | |------------------|-----------------|---------------| | Glucagon Injection Kit | Intramuscular injection | Traditional form; requires mixing before injection | | Nasal Glucagon | Nasal Spray | Easy to administer; no mixing or injection required | | Premixed Glucagon Injection | Intramuscular injection or subcutaneous injection | Pre-filled syringe; ready to use immediately |

How to Administer Glucagon Injection:

  1. Read the instructions on the kit carefully before starting.
  2. Remove the caps from the glucagon powder vial and the syringe containing the diluent.
  3. Inject the diluent into the glucagon powder vial.
  4. Gently swirl the vial until the powder is completely dissolved.
  5. Withdraw the solution back into the syringe.
  6. Inject the glucagon into the thigh, arm, or buttock.
  7. Call emergency services (911) immediately.

How to Administer Nasal Glucagon:

  1. Read the instructions on the device carefully before starting.
  2. Remove the device from its packaging.
  3. Hold the device with your thumb on the plunger and your index and middle fingers on either side of the nozzle.
  4. Insert the nozzle into one nostril.
  5. Press the plunger firmly to deliver the dose.
  6. Call emergency services (911) immediately.

Important Considerations for Glucagon Use:

  • Storage: Store glucagon kits according to the manufacturer’s instructions, typically at room temperature and away from direct sunlight and heat.
  • Expiration: Check the expiration date regularly and replace expired kits.
  • Side Effects: Glucagon may cause nausea and vomiting. If the person vomits, turn them on their side to prevent choking.
  • Effectiveness: Glucagon may not be effective in people who have depleted glycogen stores in the liver, such as those who are malnourished or have liver disease.

Addressing Common Concerns and Misconceptions

There are several common misconceptions surrounding severe hypoglycemia and its treatment. Addressing these concerns can help improve understanding and response during an emergency:

Misconception 1: "I don't need to worry about severe hypoglycemia because I can always feel when my blood sugar is low."

  • Reality: Hypoglycemia unawareness is a common condition in which individuals no longer experience the warning signs of low blood sugar. This increases the risk of severe hypoglycemia. Regular blood glucose monitoring and continuous glucose monitoring (CGM) can help detect and prevent low blood sugar events.

Misconception 2: "Giving sugar to someone who is unconscious will help them."

  • Reality: Attempting to give food or liquid to an unconscious person can lead to choking. Glucagon is the appropriate treatment for severe hypoglycemia in unconscious individuals.

Misconception 3: "Glucagon will solve everything, so I don't need to call 911."

  • Reality: While glucagon is a vital treatment, it's crucial to call emergency services (911) after administering glucagon. The person may require further medical evaluation and treatment.

Misconception 4: "If I give someone glucagon, they'll be fine immediately."

  • Reality: It can take 10-15 minutes for glucagon to raise blood sugar levels. The person may experience nausea or vomiting after regaining consciousness. Close monitoring and post-event care are essential.

Conclusion: Empowering Action Through Preparation

Severe hypoglycemia is a potentially life-threatening complication of diabetes. By developing a personalized emergency action plan, educating family and caregivers, and understanding the appropriate use of glucagon, individuals with diabetes can be empowered to respond effectively to a hypoglycemic emergency. Remember, proactive preparation, prompt recognition, and decisive action are key to ensuring the best possible outcome in these critical situations. Consistent communication with your healthcare provider, regular monitoring of blood glucose levels, and adherence to the diabetes management plan are all crucial steps in minimizing the risk of severe hypoglycemia and maintaining optimal health.
