Measure glucose on entry to ICU

BG > 220 mg/dL Start insulin 2 - 4 IU/h

BG 220 - 110 mg/dL Start insulin 1 - 2 IU/h BG < 110 mg/dL Do not start insulin but

Page 28: Bruce W. Bode, MD FACE Susan S. Braithwaite, MD FACE R. Dennis Steed, MD Paul C. Davidson, MD FACE December 15, 2003 IV Insulin Infusion Therapy: Indications,

1. Start Portland protocol during surgery and continue through 7 AM of the third POD. Patients who are not receiving enteral nutrition on the third POD should remain on this protocol until receiving at least 50% of a full liquid or soft American Diabetes Association diet.

2. For patients with previously undiagnosed DM who have hyperglycemia, start Portland protocol if blood glucose is greater than 200 mg/dL. Consult endocrinologist on POD 2 for DM workup and follow-up orders.

3. Start infusion by pump piggyback to maintenance intravenous line as shown in Appendix Table 1. 4. Test blood glucose level by finger stick method or arterial line drop sample. Frequency of blood glucose testing is as follows:

a. When blood glucose level greater than 200 mg/dL, check every 30 minutes. b. When blood glucose level is less than 200 mg/dL, check every hour. c. When titrating vasopressors, (eg, epinephrine) check every 30 minutes. d. When blood glucose level is 100 to 150 mg/dL with less than 15 mg/dL change and insulin rate remains unchanged for 4 hours (“stable

infusion rate”), then you may test every 2 hours. e. You may stop testing every 2 hours on POD 3 (see items 1 and 8). f. At night on telemetry unit, test every 2 hours if blood glucose level is 150 to 200 mg/dL; test every 4 hours if blood glucose level is less than

150 mg/dL and “stable infusion rate” exists.5. Insulin titration according to blood glucose level is performed as follows

a. When blood glucose level is less than 50 mg/dL, stop insulin and give 25 mL 50% dextrose in water. Recheck blood glucose level in 30 minutes. When blood glucose level is greater than 75 mg/dL, restart with rate 50% of previous rate.

b. When blood glucose level is 50 to 75 mg/dL, stop insulin. Recheck blood glucose level in 30 minutes; if previous blood glucose level was greater than 100 then give 25 mL 50% dextrose in water. When blood glucose level is greater than 75 mg/dL, restart with rate 50% of previous rate. c. When blood glucose level is 75 to 100 mg/dL and less than 10 mg/dL lower than last test, decrease rate by 0.5 U/h. If blood glucose level is

more than 10 mg/Dl lower than last test, decrease rate by 50%. If blood glucose level is the same or greater than last test, maintain same rate. d. When blood glucose level is 101 to 150 mg/dL, maintain rate. e. When blood glucose level is 151 to 200 mg/dL and 20 mg/dL lower than last test, maintain rate. Otherwise increase rate by 0.5 U/h. f. When blood glucose level is greater than 200 mg/dL and at least 30 mg/dL lower than last test, maintain rate. If blood glucose level is less than 30 mg/dL lower than last test (or is higher than last test), increase rate by 1 U/h and, if greater than 240 mg/dL, administer intravenous bolus

of regular insulin per initial intravenous insulin bolus dosage scale (see item 3). Recheck blood glucose level in 30 minutes. g. If blood glucose level is greater than 200 mg/dL and has not decreased after three consecutive increases in insulin, then double insulin rate. h. If blood glucose level is greater than 300 mg/dL for four consecutive readings, call physician for additional intravenous bolus orders.

6. American Diabetes Association 1800-kcal diabetic diet starts with any intake by mouth. 7. Postmeal subcutaneous Humalog insulin supplement is given in addition to insulin infusion when oral intake has advanced beyond clear liquids.

a. If patient eats 50% or less of servings on breakfast, lunch, or dinner tray, then give 3 units of Humalog insulin subcutaneously immediately after that meal.

b. If patient eats more than 50% of servings on breakfast, lunch, or supper tray, then give 6 units of Humalog insulin subcutaneously immediately after that meal.

8. On third POD, restart preadmission glycemic control medication unless patient is not tolerating enteral nutrition and is still receiving an insulin drip.

Page 44: Bruce W. Bode, MD FACE Susan S. Braithwaite, MD FACE R. Dennis Steed, MD Paul C. Davidson, MD FACE December 15, 2003 IV Insulin Infusion Therapy: Indications,

1. Obtain initial Blood Glucose and each time the Glucommander beeps and enter the value into the Glucommander. (This is necessary so the multiplier will be adjusted)

2. Diet:______ Non-caloric __________ NPO 3. DO NOT FEED FOOD CONTAINING CALORIES UNLESS

ADDITIONAL MEALTIME INSULIN IS ORDERED. (Continuous enteral or IV feeding is an exception to this order.)

4. Mix IV Insulin Drip: Normal Saline 250ml with 125 units of Regular Insulin (this

making a 0.5Units Insulin/ml mixture). Place IV Insulin Drip on controller. DO NOT USE FILTER ON LINE

5. Low Target Blood Glucose: 100 mg/dl (or ____________)

6. High Target Blood Glucose: 140 mg/dl (or ____________) 7. Multiplier: 0.02 (or_____________)

8. Max Minutes between Blood Glucose Readings: 120 minutes (or ____________)

Note: Glucommander will beep for new blood glucose more frequently until glucose is stabilized. Obtain and enter BG value EVEN if the insulin drip is at 0 units/hr. The insulin drip will need to be restarted if the BG has increased above low target range.

9. Hypoglycemia Treatment: If BG < 80 mg/dl administer D50 according to the formula: (100 – BG) x 0.4 = __________ cc D50 IV Push

5802 Runs over 120,618 hours.

Correction of hyperglycemia:

Mean starting BG=259 mg/dL (SD 127).

Mean stable <150 after three hours.

Subsequent stability in target range for 60 hrs.

Hypoglycemia:

BG’s <50 were 0.6% of total BG’s.

What is the glucose threshold and target glucose for IV insulin in acute MI, pre-CABG, other states, etc?

<110 mg/dl or <140 mg/dl ? What is the best IV insulin infusion protocol?

What is the best way to transition to SC?
