Introduction l.jpg
Introduction

  • Diabetes

  • affects 20 million people in US alone (7% of the population)

  • considered an epidemic by the Centers for Diseases Control and Prevention (CDC)

  • cause of diabetes continues to be a mystery


Practical skills l.jpg
Practical Skills

To receive CBT or OTEP credit, you must perform the following practical skills:

  • indicate the need for ALS and/or immediate transport (SICK)

  • perform blood glucometry and record findings

  • provide oral glucose (if indicated)

  • perform proper "after-care" instructions

Practical Skills Checklist available at EMS Online.

Terms l.jpg
Terms

diabetic coma — An unconscious state caused by high blood glucose. Dehydration and acidosis are associated symptoms.

diabetes — A metabolic disorder in which the ability to metabolize carbohydrates is impaired, usually because of a lack of insulin or interference with the effects of insulin.

diabetic ketoacidosis — A condition resulting from diabetes characterized by hyperglycemia and acidosis.

glucose — one of the basic sugars; it is the primary fuel, along with oxygen, for cellular metabolism.

hyperglycemia — Excess concentration of glucose in the blood.

hypoglycemia — Deficient level of glucose in the blood.


Terms5 l.jpg
Terms

insulin — A hormone produced by the pancreas that enables sugar in the blood to enter the cells of the body; it is used in synthetic form to treat and control diabetes.

ketoacidosis — A condition resulting from metabolism of fatty acids.

kussmaul respirations — Deep, rapid breathing; usually the result of an accumulation of certain acids when insulin is not available in the body.

type 1 diabetes — A type of diabetes that usually starts in childhood and requires insulin injections for treatment. Previously referred to as "juvenile diabetes."

type 2 diabetes — A type of diabetes that usually starts in later life and often can be controlled through diet and oral medications. Previously referred to as "adult onset diabetes."


Glucose l.jpg
Glucose

  • body's cells need it to function properly

  • body’s major source of energy

  • without it, brain cells rapidly suffer permanent damage

  • Food is digested by the body into three main nutrients:

    • fats

    • carbohydrates

    • proteins

Glucose is a simple carbohydrate and

the first to be absorbed into the blood.


Insulin l.jpg
Insulin

  • helps glucose enter cells and produce energy

glucose (sugar)

insulin

cell

energy

  • In a healthy person, rising blood glucose levels stimulate the pancreas to secrete insulin. Insulin acts like a funnel that directs glucose into the cells.


Type 1 l.jpg
Type 1

  • body does not produce insulin

  • Left undiagnosed or untreated, lack of insulin causes hyperglycemia and the Three P's:

    • polydipsia (constant thirst)

    • polyuria (excessive urination)

    • polyphagia (ravenous appetite)


Type 2 l.jpg
Type 2

  • body does not produce enough insulin or cells ignore what is produced

  • most common form of diabetes (nearly 90% of all cases)

  • can be controlled by diet and exercise, oral medication or insulin


Gestational diabetes l.jpg
Gestational Diabetes

  • Form of diabetes that can occur during the 24th-28th weeks of pregnancy.

  • In some cases:

    • blood glucose level returns to normal after delivery

    • symptoms are usually mild and not life-threatening

    • increased glucose levels are associated with larger birth weight, increased rate of prenatal complications, including birth trauma, hypoglycemia and jaundice

  • Risk factors include:

    • maternal age of more than 25

    • family history of diabetes

    • obesity

    • previous birth of an 9 pound or larger baby

    • unexplained death of a previous infant or newborn


Hypoglycemia l.jpg
Hypoglycemia

  • Hypoglycemia occurs as a result of:

    • too much insulin--accidental or intentional

    • low food intake

    • too much exercise

Hypoglycemia is a true life-threatening emergency.

Without sugar to the brain, unconsciousness may occur

and permanent brain damage can quickly follow.


Hypoglycemia continued l.jpg
Hypoglycemia, continued

  • Signs and symptoms of hypoglycemia develops quickly over a period of minutes and may include:

    • cold, pale, clammy skin

    • abnormal or hostile, bizarre behavior; patient may appear intoxicated

    • shaking, trembling, weakness

    • full, rapid pulse

    • normal or elevated blood pressure

    • normal or rapid respirations

    • dizziness, headache, blurred vision

    • extreme hunger

    • slurred speech

    • seizures, loss of consciousness

Most of the diabetics in crisis present with hypoglycemia.


Hyperglycemia l.jpg
Hyperglycemia

The initial presentation of undiagnosed diabetes is hyperglycemia.

  • Hyperglycemia is a chemical imbalance:

  • cells use other foods for energy

  • ketones are produced and blood becomes concentrated

  • kidneys respond by excreting glucose and ketones

  • Hyperglycemia occurs most often when:

    • a person is an undiagnosed diabetic (initial presentation)

    • a diagnosed diabetic becomes ill (flu, vomiting)

    • a diagnosed diabetic takes too little insulin


Hyperglycemia continued l.jpg
Hyperglycemia, continued

  • Signs and symptoms of hyperglycemia can develop slowly over a period of days and may include:

    • nausea, vomiting, or abdominal pain

    • weak, rapid pulse (possibly irregular)

    • warm dry skin

    • normal to profoundly decreased blood pressure

    • altered LOC

    • fruity odor on breath

    • kussmaul respirations


Slide15 l.jpg
DKA

  • diabetic ketoacidosis

    • the natural progression of profound hyperglycemia

    • body is burning fat instead of sugar

    • a serious condition that can lead to diabetic coma, or death

    • more common in people with type 1 diabetes

  • Ketoacidosis usually develops slowly. However, if vomiting occurs, this life-threatening condition can develop in a few hours.

  • Signs and symptoms of DKA include:

    • frequent urination, dehydration and extreme thirst (the 3 P's)

    • high blood glucose levels

    • high levels of ketones in the urine

    • fruity breath from blowing out ketones


Patient care l.jpg
Patient Care

SICK or NOT SICK

  • Initial Assessment

    • guides the initial path of treatment

    • quickly assess a patient

    • make a decision

A SICK patient is one who can die quickly unless you initiate aggressive BLS and ALS treatment and rapid transport.

A NOT SICK patient is one who can be ill or injured, but not severely enough to be life threatening.


Patient care continued l.jpg
Patient Care, continued

SICK or NOT SICK

  • Key clinical indicators

    • nature of illness

    • glucose value

    • mental status (LOC)

    • respirations (rate and character)

    • pulse (rate and character)

    • skin signs and color

    • body position

The SICK/NOT SICK choice is a very important medical decision.


Patient care continued18 l.jpg
Patient Care, continued

  • Glucometry

    • most effective way to determine the level of a diabetic emergency

  • Good questions to ask:

  • When did you eat last?

  • Have you tested your blood glucose today?

  • Have you taken your insulin or medication today?

  • Has there been a change in your health, stress level, or exercise?

  • When did the symptoms begin?

A low reading of 50 mg/dl for example, may indicate hypoglycemia—

a high reading of 400 mg/dl may indicate hyperglycemia.


Slide19 l.jpg
LOC

  • common symptom of a diabetic emergency

  • untreated hypoglycemia will result in loss of consciousness

  • can quickly cause significant brain damage or death

  • An altered LOC is also a possibility for someone who may be having a stroke, is drunk or has a head injury. From the moment of dispatch, keep an open mind about the potential causes of a chief compliant.


Airway l.jpg
Airway

  • Unconscious patients

  • are at risk of losing their gag reflex as indicated by the inability to swallow

  • cannot reject foreign materials like vomit

  • tongue can relax and block the airway

  • Airway management includes:

  • Appropriate positioning

  • Maintaining the airway

  • Have suction device ready

  • High flow oxygen with appropriate device

  • Assisting ventilations as needed


Treatment l.jpg
Treatment

  • The key principles of treatment for a diabetic episode include:

    • take necessary BSI precautions

    • request medics if indicated—determine SICK or NOT SICK

    • perform glucose check

    • position upright and give oral glucose (if gag reflex is present as indicated by the ability to swallow)

    • monitor vital signs and LOC

    • document times and levels of glucose checks

SICK or NOT SICK


Summary l.jpg
Summary

Diabetes is a disease that refers to a body's inability to produce insulin, or use insulin effectively.

Diabetics must balance their medications, food intake, and activity level. Diabetic emergencies can occur when any of these elements are out of balance.

Type 1 diabetics do not produce insulin, and type 2 diabetics produce inadequate amounts, or don't effectively use what they do produce.


Summary23 l.jpg
Summary

Glucometry is the best way to determine whether a patient is hypoglycemic or hyperglycemic. The speed of onset, skin signs, and quality of respirations are other clinical indicators.

The signs and symptoms of a diabetic emergency include an altered level of consciousness.

Maintain a high index of suspicion for patients who appear intoxicated, or show signs of a head injury.

Treatment includes maintaining the airway, providing oral glucose, and seeking advanced medical treatment.
