Type I Diabetes Mellitus Flashcards
Subtypes
Type 1A: Immune-mediated B-cell destruction
Type 1B: Idiopathic (15%)
Age presentations DM TI
4-6 years of age and 10-14 years of age
DMTI Most common presentation
1st: New onset of chronic polydipsia, polyuria, and weight loss with hyperglycemia and ketonemia or ketonuria
2nd: DKA
Diagnostic Criteria
- Fasting plasma glucose ≥126 mg/dLon at least two occasions OR
- Symptoms of hyperglycemia and a plasma glucose ≥200 mg/dL OR
- Plasma glucose ≥200 mg/dL measured two hours after a standard glucose load in an oral glucose tolerance test (OGTT)
Type I Treatment regimen
Includes long-acting basal insulin with pre-meal and pre-snack boluses of rapid-acting insulin
Clinically important hypoglycemia
<54 mg/dl
Whipples Triad
Symptoms consistent with hypoglycemia
Low plasma glucose concentration
Relief of symptoms after plasma glucose level is raised.
Rule of 15
Check blood sugar
Give 15 grams of simple carbohydrate by mouth
Re-check blood sugar in 15 minutes
Repeat until blood sugar is above 100mg/dl
IV Glucose follow-up
50% solution followed by dextrose
Hypoglycemic coma
- BG <30 mg/dl
- Normal pH
- Neg Glucosuria
- normal ketones
- Normal osmolality
- CNS S/S
Hyperosmolar Hyperglycemic State (HHS)
- Serum glucose 1000
- mild or absent ketosis
- INC Plasma osmolality > 320
- CNS S/S
- Minimal acidosis venous pH
- insidous development; Signs of volume depletion
DKA Tx
- ABCs - Airway, Breathing, circulation
- Fluid + Electrolytes (Esp K+)
- Administer Insulin after potassium > 3.3
- Glucose goal is 150-250
