Anatomy and Physiology:
Diabetes

Pancreas
– Located in the
abdomen attached
to the intestines but
behind the stomach
– Responsible for the
Production of the
hormone Insulin
3/11/2016
Hormone: Insulin




Secretion by the Pancreas from the Beta Cells on
the Islets of Langerhan
It is required by for the intracellular metabolism
of glucose
Its release is primarily stimulated by glucose
levels
Other stimulus for the its release include
– Amino Acids
– Fatty Acids
– Ketones
3/11/2016
How is Insulin used in Liver
cells?


Glucose enters Liver cells
Insulin is needed to activate the hormone
Glucokinase
– Glucokinase Promotes phosphorylation of
glucose
– First step in glucose metabolism

Activates the hormone Glycogen
Synthetase
– Necessary for glycogen formation
3/11/2016
What is Glycogen?



It is stored sugar
We use it as a reserve energy supply
We only store sugar when insulin is
present
– Insulin doesn’t do the work Glycogen
Synthetase does
– But insulin must start the process off
3/11/2016
How does Insulin used in Muscle
cells?

Resting muscle
– Insulin is needed to transport glucose across
the cell membrane
– Insulin increases glycogen synthetase
– Insulin inactivates the enzyme Phosphurylase
– Insulin's presence facilitates Amino acid
uptake and protein synthesis while
preventing protein catabolism
3/11/2016
How does Insulin used in Muscle
cells?

Active muscle
– Glucose can enter without insulin
– Glucose is oxidized to CO2 and H2O for
energy production
3/11/2016
How does Insulin used in
Adipose tissue?




Insulin is necessary for transport of
glucose across cellular membrane
Promotion of glucose metabolism, fatty
acid synthesis
Insulin will combine with fatty acids
produced in the liver and in fat cells to
form Triglycerides
Insulin presence decreases Lipolysis

General Pathophysiology of
Diabetes Mellitus

This condition is caused by either
– Absolute or relative lack of Insulin
– Or ineffective utilization of Insulin

In Insulin Dependent
– Absolute lack of Insulin

In Noninsulin Dependent
– Normal or near normal levels of Insulin
3/11/2016
When Insulin levels are normal

It is usually ineffective utilization of
Insulin
– Caused by a decrease number of Insulin
Receptor Cells

Or Impaired Binding of Insulin to body
cell
– Caused by a receptor defect
3/11/2016
Problems associated with
alterations in metabolism


The are seen when there is a lack,
deficiency or under utilization of Insulin
These problems are
–
–
–
–
Hyperglycemia
Hypoglycemia
Diabetic Ketoacidosis
Nonketonic Hyperosmolar Coma
3/11/2016
Hyperglycemia


Caused by several factors
Over production of glucose due to an increase
in
– Glucogenesis

The formation of glycogen from noncarbohydrate sources
such as Amino Acids or Fatty Acid
– Glycogenolysis

Hydrolysis of glycogen into glucose
– And a decrease in peripheral utilization of glucose
3/11/2016
Hyperglycemia


Caused by Protein Catabolism and loss of
Amino Acids from muscle.
Caused by impaired Triglycerides
Synthesis
– Which increases the release of Free Fatty
Acids from Adipose Tissue which increases
Beta Oxidation of Fats
3/11/2016
Diabetic Ketoacidosis (DKA)




Most frequently seen in IDDM (Insulin
Dependent Diabetes Mellitus)
Caused by Acute Insulin Insufficiency and is
usually precipitated in the known Diabetic by
stressors that increase Insulin needs
When there is insufficient Insulin for appropriate
metabolism of glucose, fats, proteins
This causes inappropriate utilization of glucose,
resulting in Hyperglycemia
3/11/2016
What does this mean to us?



Hyperglycemia increases dehydration and
Lactic Acid build up
Hyperglycemia causes Acidosis
Acidosis results in hypoxia and coma
3/11/2016
Who will we see like this?

New onset (undiagnosed) Diabetics
– Particularly young kids between 7 and 13
years old

Noncomplient IDDM patients
3/11/2016
Frequent precipitating factors:




Infection (serious
local or systemic)
Urinary infections
Respiratory
infections
Major Surgery




Trauma
Major illness
Therapy with
Steroids
Emotional upset or
excessive stress
3/11/2016
Signs and Symptoms of
DKA/Hyperglycemia


Are usually associated with acidosis and
the bodies compensatory mechanisms
Of Gradual onset
– Usually greater than 48 hours
3/11/2016
Signs and Symptoms of
DKA/Hyperglycemia by Body Systems

Respiratory system

– Body's trying to remove
acid by elimination of
Ketones which causes
– Acetone Breath (fruity)
– Kussmaul's Respiration’s

– Nausea and Vomiting

Caused by acidosis
– Polyuria

Central Nervous System
– Change in mental status
– Caused by Dehydration
Acidosis & lack of glucose
GI & GU Systems


attempting to remove
ketones
Which causes
dehydration
Circulatory System
– Hypotension
3/11/2016
Other Signs and Symptoms of
DKA/Hyperglycemia

Loss of skin turgor/dry mucosa



Polyphasia
Warm/dry skin
Tachycardia to Normal pulse
3/11/2016
Hypoglycemia


Major complication for patients treated
with Insulin and Oral Hypoglycemic
agents
Usually caused by too little food or too
much Insulin/Oral Hypoglycemic agents
3/11/2016
Hypoglycemia


Alterations in mental status and bizarre
behavior are caused by Brain cells being
starved for food
The longer the duration of decrease, or no
glucose, reaching Brain cells, the greater
the chance of/or increasing the amount of
damage sustained





Initiate IV access 0.9%
Sodium Chloride
Administer Dextrose 50% in
Water if D-Stick is below
100mg/dl
Administer Thiamine 100mg
IV or IM
Administer Glucagon IM if
no IV access
3/11/2016
Note for ALS Providers



Consult with Medical control for additional
Amp(s) of D50W
The Need for additional dosages of D50W is rare
but should be guided by repeated dextrose
analysis
Post D50W administration
– you can expect a Glycogen Stores release
– This may occur approximately an hour after the
D50W which will raise the blood glucose again, but
only if there are any glycogen stores left

Summary




Diabetes is a disease that effects the bodies
ability to properly use glucose for metabolism
The conditions of Diabetes we see are caused
by the body compensatory mechanism when the
disease is unchecked
Management of a Diabetic in an acute setting is
to stabilize the ABCs and provide sugar
Long term management is designed to prevent
peaks and valleys in blood sugar which are the
causes of long term diabetic problems
