YASH RAMAWAT M.N. FINAL
Diabetes meaning
a disorder of the metabolism causing excessive thirst and the production of large amounts of urine.
Ketoacidosis Pathological metabolic state associated
with high concentrations of ketone bodies
Meaning of diabetic ketoacidosis….
A serious pathological metabolic state in which excessive amount of keton bodies accumulate in body due to lack of insulin ……….
How lack of insulin develop acidosis
Insulin Deficiency
Glucose uptake Proteolysis Lipolysis
Amino Acids
GlycerolFree Fatty Acids
GluconeogenesisGlycogenolysis
HyperglycemiaKetogenesis
AcidosisOsmotic diuresis Dehydration
PATHOPHYSIOLOGY
Signs and Symptoms of DKA
• Polyuria, polydipsia– Enuresis
• Dehydration– Tachycardia– Orthostasis
• Abdominal pain– Nausea– Vomiting
• Fruity breath– Acetone
• Kussmaul breathing• Mental status
changes– Combative– Drunk– Coma
Counterregulatory Hormones - DKA
Increases insulin
resistance
Activates glycogenolysis
and gluconeogenesis
Activates lipolysis
Inhibits insulin secretion

If serum K+ above 5 do not give k+ check it every 2hr
If serum potassium between 3.3 to 5 mEq/l then 20 mEq in each liter of iv fluid
Assess need for bicarbonate
pH < 6.9
NaHco3( 100 mmol ) dilute in
400 ml water at 200ml/hr

Repeat HCO3
administration
q 2h untill pH > 7.0.
WHEN SERUM glucose reaches 250 mg/ dl
Change to 5% glucos with 0.45% Nacl at 150- 250 ml/hr with adequate insulin(0.05-0.1U/kg/hr insulin 5-10 U SC every 2 hr) to keep the
serum glucose between 150-250 mg/dl until metabolic control is achieved
Nursing Diagnosis
• FLUID VOLUME DEFICIT RELATED TO: OSMOTIC DIURESIS DUE TO HYPERGLYCEMIA, EXCESSIVE DISCHARGE: DIARRHEA, VOMITING; RESTRICTION INTAKE DUE TO NAUSEA, MENTAL MESS.
• MBALANCED NUTRITION: LESS THAN BODY REQUIREMENTS RELATED TO: INSUFFICIENCY OF INSULIN, DECREASED ORAL INPUT, HIPERMETABOLISME STATUS
• RISK FOR INFECTION (SEPSIS) RELATED TO: INCREASED LEVELS OF GLUCOSE, DECREASED LEUKOCYTE FUNCTION, CHANGES IN THE CIRCULATION.
• RISK FOR SENSORY-PERCEPTUAL ALTERATIONS RELATED TO: KETIDKSEIMBANGAN GLUCOSE / INSULIN AND / OR ELECTROLYTES.
• FATIGUE RELATED TO: DECREASED METABOLIC ENERGY PRODUCTION, INSUFFICIENCY OF INSULIN, INCREASING ENERGY DEMAND.
