About This Presentation

Description : Check out this medical PowerPoint presentation titled "Diabetic Ketoacidosis (DKA) & Hyperglycemic Hyperosmolar State (HHS)" by Ulrich K. Schubart, MD.

This medical PowerPoint presentation talks about Diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar state (HHS). Both DKA and HHS are serious medical emergencies that can occur in people with diabetes. They are both caused by high blood sugar levels, but there are some key differences between the two conditions.

Compensatory Hyperventilation in DKA From UpToDate Kety et al. JCI 1948
Slide 5-

DKA/HHS Precipitating Factors Infection Pneumonia Gastroenteritis UTI Sepsis Meningitis Influenza Mucormycosis Emotional Problems Trauma Acute Pancreatitis Myocardial Infarction Stroke Endocrine Acromegaly Thyrotoxicosis Cushing’s S. Omission of Antidiabetic Mx’s Drugs Any major Stress/Acute Illness
Slide 6-

DKA/HHS Drugs that can Precipitate Psychotropic Drugs Chlorpromazine Clozapine Risperidone Loxapine Steroids Immunosuppressants Beta Blockers Calcium Channel Blockers Diuretics Anticonvulsants Diazoxide
Slide 7-

DKA/HHSPathogenesis Precipitating Factors Glucagon Catecholamines Cortisol Growth Hormone Absolute Insulin Deficiency Relative Insulin Deficiency Lipolysis FFAs Proteolysis Gluconeogenesis Ketogenesis Glycogenolysis Minimal Lipolysis Gluconeogenic Substrates Ketoacidosis Hyperglycemia Hyperosmolality Glucosuria (Osmotic Diuresis) Loss of Water & Electrolytes Triglycerides Hyperlipidemia Dehydration Decreased GFR

Slide 12-

DKA/HHSGlucotoxicty & Lipotoxicity Relatively Short Term: Reversible Inhibition of: a) Glucose Uptake and Utilization in Insulin-Responsive Target Tissues b) Insulin Secretion Long-term: a) & b) + Apoptosis of Beta-Cells
Slide 13-

DKA/HHSEssential to R/o Infection Look for meningeal signs - Head CT/MR followed by LP may be indicated Look for necrotic lesions in nasal turbinates to r/o mucormycosis For abdominal pain consider appendicitis cholecystitis pancreatitis diverticulitis PID Obtain CXR Check urine sediment
Slide 14-

DKA/HHS Hyperosmolality Measure and Calculate Serum Osmolality = 2 x measured Na+ (mEq/l) + glucose (mg/dl) /18 + BUN (mg/dl)/2.8 Osmolar Gap = Measured – Calculated Serum Osmolality Effective Serum Osmolality OsmEff (>320 =HHS) = 2 x measured Na+ (mEq/l) + glucose (mg/dl) /18
Slide 15-

DKA/HHS Sodium Correction Corrected Sodium = Measured Sodium + 1.6 x plasma glucose (mg/dl) – 100 100
Slide 16-

DKA/HHS Metabolic Acidosis Plasma Anion Gap = Na+ - [Cl- + HCO3-] (mEq/l)

DKA/HHSEssential Components in Tx IV Fluids 2-3 L 0.9% saline during first 3 h Subsequently, 0.45% saline at 150-300 ml/h Add 5% dextrose when plasma glucose reaches 250 mg/dl
Slide 24-

DKA/HHSEssential Components in Tx Insulin 10 U/h iv infusion of short-acting insulin Increase rate 2-10 fold if no response by 4 h Decrease to 1-2 U/h when acidosis is corrected Administer sc insulin before stopping iv infusion
Slide 25-

DKA/HHSEssential Components in Tx Potassium 10-20 mEq/h when plasma K<6.0, ECG normal, urine flow documented 40-80 mEq/h when plasma K <3.5 or if bicarb is given
