OBJECTIVES

• Understand the impact of glycemic control on

clinical outcomes for critically ill surgical and

medical patients

• Review current guidelines and glycemic targets

for critically ill patients

• Implement strategies for safe and effective

glycemic control during the ICU stay and on

transition out of the ICU

CAUSES OF INPATIENT

HYPERGLYCEMIA

• Illness related “stress” – counter regulatory

hormones and cytokines cause insulin

resistance

• Undiagnosed diabetes mellitus

• Medications: steroids, immunosuppressants,

sympathomimetics, anesthetic agents,

octreotide

• Parenteral and enteral nutrition

• Physical Inactivity

• Inappropriate insulin use e.g. Sliding scale

STRATEGIES TO ACHIEVE GLYCEMIC

CONTROL IN CRITICALLY ILL PATIENTS

33

ADMISSION #1 – CHEST PAIN

• 68 year old male admitted with chest pain and found to have AMI

and CHF

• Type 2 DM for 14 years, HTN, Hyperlipidemia, Gout

• Outpatient DM Meds: Metformin 1000mg bid, Glyburide 5mg bid

• Exam: Lungs w/ rales, 2+ LE edema

• Labs: Admission glucose 316 mg/dL HgbA1c 9.3%, creatinine 2.5,

LFT’s- 2.5 X normal

• Echo shows LVEF 25%

• Admitted to CCU after cardiac catheterization with glucose now

250 mg/dL

How should we treat this patient?

1. Continue metformin and increase the dose of glyburide to 10 mg

bid

2. Start SLIDING SCALE SLIDING SCALE SLIDING SCALE SLIDING SCALE subcutaneous insulin Q4-6 hours

3. Start Insulin Infusion with a glucose target of 110-140 mg/dl

INDICATIONS FOR INTRAVENOUS

INSULIN THERAPY: SUMMARY

• Diabetic ketoacidosis

• Nonketotic hyperosmolar state

• Critical care illness (surgical, medical)

• Postcardiac surgery

• Myocardial infarction or cardiogenic shock

• NPO status in Type 1 diabetes

• Labor and Delivery

35

ADMISSION #1 –

CONTINUED

• Over the next 24 hours, the glucose control improved into the desired target and he is medically optimized

• He now has proceeds to surgery and has a 3 vessel CABG

• Postop, he is admitted to the surgical ICU on epinephrine and vasopressin drips for hypotension

• His initial glucose in the ICU is 251 mg/dl

How do we manage his glucose?

1. SLIDING SCALE insulin Q 4-6 hours

2. Start long and short acting insulin for basal- bolus insulin therapy



36

ADMISSION #1 –

CONTINUED

• Over the next 24 hours, the glucose control reaches target range

• Pressors are weaned off and he is extubated

• A diet is ordered and plans are started to transfer to the floor

What do we do next?

1. Restart metformin and increase glyburide dose to 10mg bid

2. Turn off insulin infusion and immediately start SLIDING SCALE

insulin Q 4-6 hours

3. Transition to a long + short acting insulin for basal- bolus insulin

therapy

DANGERS OF SLIDING-SCALE

INSULIN REGIMENS

• Reactive to after hyperglycemia-- provides supplemental insulin after hyperglycemia occurs

• No basal (long term) insulin coverage:

� Will cause DKA in patients with Type 1 Will cause DKA in patients with Type 1 Will cause DKA in patients with Type 1 Will cause DKA in patients with Type 1 diabetesdiabetesdiabetesdiabetes

• Does not consider nutritional changes or diurnal insulin requirements

• Non physiologic dosing that results in:

– Increased incidence of hyperglycemic and hypoglycemic episodes1

CAUTIONS IN INSULIN

DOSING…

• Changing steroid doses

• Changing pressor requirement over past 24

hours

• Changing renal function (rapidly decreasing

urine output or GFR)

• Nutrition changes

• Improving infectious status

• Hypoglycemic Events

42

ADMISSION #2 : FEVER

• 66 year old female admitted with fever of 103 F, SOB

and hypotension.

• Intubated and started on pressors and admitted to

Medical ICU

• Found to have a multilobar pneumonia with SIRS

• No history of Type 2 Diabetes but has HTN ,

Hyperlipidemia, CAD, COPD

• Labs: Glucose= 225 mg/dL, repeat accucheck 253

mg/dL HgbA1c = 5.9% Creatinine = 1.8 AST/ALT =

normalHow should we treat this patient?

1. No therapy needed as this is acute hyperglycemia and not diabetes

2. Start SLIDING SCALE SLIDING SCALE SLIDING SCALE SLIDING SCALE subcutaneous insulin Q4-6 hours

43

ADMISSION #2:

CONTINUED

• Patient was managed on insulin infusion and reached the

target

• Over the next 48 hours, patient is supported with

mechanical ventilation, Norepinephrine, stress dose

hydrocortisone, iv antibiotics

• Still not improved and TPN is started due to ileus

• Insulin infusion has been titrated up to 5-7 units/hr and she

is requiring >140 units of IV insulin per 24 hours

• Labs: Cr = 2.6, LFTS now 3x normal

What is the next step?

1. Continue iv insulin infusion as is

2. Transition to basal bolus subcutaneous insulin regimen

3. Add NPH or Lantus in addition to iv insulin

4. Add Regular insulin into the TPN formula

ADMISSION # 2 - ADDING

INSULIN IN TPN

• Insulin is more effective when added to the

TPN than when delivered in another infusion

• Delay in preparation of TPN, often 12-24 hours

later requires planning

• Be conservative, add only 20-50% of previous

24 hour iv insulin requirements needs to be

delivered via TPN

• Watch for clinical and medication changes and

change insulin in TPN in advance in advance in advance in advance to avoid

hypoglycemia.

Advantages:• Glucose dependent insulin

stimulation prevents hypoglycemia

• Glucagon inhibition may be useful in

the maladaptation of the stress

response

• Suppression of hepatic glucose

• Increased tissue insulin sensitivity

• Potential cardiovascular benefits

with improved cardiac function,

reduced infarct size

• Less nursing time to monitor

glucose and administer insulin

Disadvantages:• Small, limited studies investigating

use in critically ill patients

• Usually compared to placebo, not

insulin

• High incidence of GI side effects

• Rescue insulin therapy often

needed

• Long term effects unknown

• More studies needed
