How is diabetes newly diagnosed? |
|
Definition
FBG > 126 Random BG > 200 A1C > 6.5 Can be hospital related, reverts to normal after discharged. |
|
|
Term
Why is glucose higher in the hospital or infection? |
|
Definition
Stress response increases glucose, decreases insulin - Increased reactive oxygen, immune dysfunction - Leads to increased cell injury, acidosis - A NEW hyperglycemia patient will have a longer hospital stay |
|
|
Term
How does blood sugar affect mortality? |
|
Definition
If BG > 150, mortality increases significantly. |
|
|
Term
What are the goals for ICU and non-ICU patients? |
|
Definition
- Critical (ICU) patients goal 140-180, closer to 140 better for the patient. - Non-critical (non-ICU) goal <140 fasting, random goal <180. Consider modifying if BG<100, required if <70 |
|
|
Term
What do studies say about ICU patients w/ diabetes? |
|
Definition
Intensive care (BG goal 80-110) decreases morbidity and mortality. No difference seen in-hospital death, but benefits seen in discharge |
|
|
Term
What does the NICE-SUGAR trial say? |
|
Definition
Unexpected result - tight glucose control increases risk of death. The reason why goal is a RANGE rather than specific. |
|
|
Term
What do trials say about non-ICU patients? |
|
Definition
There are no trials about non-ICU patients |
|
|
Term
What is the therapy of choice for ICU and non-ICU patients? |
|
Definition
ICU - insulin infusion. IV regular insulin, not analogs Non-ICU - SQ insulin Preferred therapy is always insulin. Oral agents disliked. |
|
|
Term
What are concerns about using oral agents in the hospital? |
|
Definition
- time to reach steady state - AEs - administration w/ food absorption |
|
|
Term
What are clinical pearls on SUs (secretagogues) in the hospital? |
|
Definition
ALWAYS watch renal function b/c eliminated by kidneys - Glyburide - ACTIVE metabolites, do not recommend for use - Glipizide - mostly inactive, renally excreted - Glimepiride - 2C9 active metabolite Ischemic preconditioning |
|
|
Term
What are clinical pearls about metformin in the hospital? |
|
Definition
- Risk of lactic acidosis: CHF, hypoperfusion due to damage, renal insufficiency (hold for contrast dye), older age, COPD - GI discomfort |
|
|
Term
What are clinical pearls for TZDs in the hospital? |
|
Definition
- Rosiglitazone associated with ischemic events - Edema common - Delay in onset, not good in the hospital |
|
|
Term
How is IV insulin dose determined? |
|
Definition
50% of home regimen divided over 24 hours |
|
|
Term
What are the components of non-ICU therapy |
|
Definition
- Basal - rapid + long acting - Nutritional - may be a meal or IV - Supplemental/Correction - corrects for high readings If type 1, will need all 3. sickness increases insulin demand. |
|
|
Term
What insulin is used for hospital basal dosing? |
|
Definition
Insulin glargine/Lantus QPM, check BG in the morning. or Levemir in place of Lantus |
|
|
Term
Which insulins are used for nutritional insulin options? |
|
Definition
Short acting insulins such as novolog before meals (TID), or humalog Lag times: - BG 80-99 lag time 0 - BG 100-199 lag time 10-20 - BG 20-299 lag time 20-30 - BG >300 lag time 30-40 |
|
|
Term
What insulins are used for correction? |
|
Definition
Never use regular insulin, always use an analog 1500 (regular) or 1800 (analog) / total daily insulin = sensitivity factor. Use rapid acting analogs. |
|
|
Term
When are insulin pumps used? |
|
Definition
Patients and providers are familiar with use and dosing - Bolus dosing: 500/total insulin = carb ratio |
