Does the body have a base insulin level?

 

What happens after meals with the insulin level?

Definition

--Yes the body produces a base insulin level

 

--After a meal the body secrete a large insulin dose.

Term
Dawn Phenomenon

BID dosing

Term

Empiric initial dosing in Type 1 DM

Definition

based on actual body weight

--0.3-0.5 units/kg/day

--70kg patient = 20-35 units/day

 

(with ketosis, illness, or growht: 1-1.5 units/kg/day)

 

--three or more injections/day to mimic cycle

Term
Honeymoon period
Definition

temporary recovery of endogenous insulin secretion

 

--markedly decrease insulin needs (cannot totally stop insulin because ATB's can be produced against it and can cause insulin resistance)

 

-.2-.5 units/kg/day

Term

Typical dosing regimine in type 1 DM

 

Definition

Long acting basal plus short acting bolus

--AM(short/rapid) [R, lispro,aspart]

--NOON(short/rapid) [R, lispro,aspart]

--PM(short/rapid) [R, lispro,aspart]

 

--HS (long) [glargine]--provide the basal rate

 **most felxible in meeting patients needs**

Term

  • volume of the dose
Term
Insulin injection technique:
Definition
  1. Roll to bring to body temp (NPH needs to be resuspended)--roll slowly
  2. watch for air bubbles which can affect dose
  3. leave needle in skin for 5 sec
  4. proper disposal of each needle
Term
What insulin products should not be mixed?
Definition
  1. glargine--low pH

Storage of insulin

Definition
  • refrigerated can be stabel till experation
  • insulin in use does not need to be refrigerated
  • discard open vials after 30 days
Term
Insulin pumps
Definition
  • continuos sub Q administration
  • regular or short acting insulin
  • control basal rate
  • easily programmed for bolus meal injection
Term

Hypoglycemia

(managment)

Definition

possible advers event of DM

--cause: to much insulin, missed meals, low carbs, increase physical activity, increased insulin absorption

treatment: rule of 15, longer acting carbs if not near meal time, glucagon injection

 

Term
Rule of 15
Definition
  • treatment of hypoglycemia--if concious give 15 grams of Carbs PO
  • recheck in 15 min.
  • if <70mg/dL give 15 more grams

--if unconcious glucagon injection

Term
Hyperglucemia
Definition

>140 mg/dL

treatment: adjustment in the next insulin dose

      bolus of short acting insulin

 

Sever can lead to DKA

Term
Aspart
Definition

Rapid acting insulin

5-15 min onset

.5-1.5 hr peak

3-5 hr druation

Sub Q only

Term
How much should be given at meals  and basal requirements?
Definition

--Basal shoudl be 50% of total daily insulin

 

--Meals should be 50% of total daily insulin divided between breakfast/lunch/dinner (20%/15%/15%)

Term

DKA

(management)

Definition
  • Rapid Hydration of patient (fluids IV)--when glucose falls to 200-300 add 5%dextros
  • Insulin IV--bolus and maintenance (remember to flush to prime binding sites)
  • Potassium
  • Phosphate (if <1mg/dL)
  • Sodium bicarb--not unless pH<6.9
Term

Sick Day management

Definition
  • Continue insulin even if food intake decreases (stress increases insulin requirements)
  • Fluids
  • Test urine for Ketones
  • Blood glucose concentrations every 4hrs
  • supplemental insulin doses for individual algorythm based on blood glucose (1-2 units every 30-50mg/dL above target level)
  • Call MD glucose >240 md/dL
