Orders with a Box Require a Check Mark to Activate Initiation of IV Insulin Discontinue all diabetic medication orders, including: oral medications, insulin sliding scale, or insulin pump. Patient should have continuous source of caloric intake, approximately equal to 5 grams of glucose per hour for the duration of the insulin infusion period. (E.G.,D5W at 100 ml/hr, D10W at 50 ml/hr, tube feed at ½ of goal or greater, TPN.) Glucose source: Please indicate which glucose source is present Intravenous fluid D5W at 100 ml per hr D5 at (minimum of 100 ml per hour) D10W at 50 ml per hr D10 at (minimum of 50 ml per hour) Patient is on tube feed at ½ of goal or greater Patient is on TPN After glucose source has been initiated, test blood glucose level and start infusion rate as instructed below: (STANDARD CONCENTRATION OF HUMAN REGULAR INSULIN 1 units per ml) Blood Glucose (mg/dl) Regular Insulin (Bolus) Regular Insulin (infusion per hour) 110 220 Bolus 2 units IV infusion / hour 221 300 6 units IV 4 units IV infusion / hour Greater than 300 mg/dl 10 units IV 4 units IV infusion /hour Maintenance of IV Insulin (Goal Range 80 to 110 mg per dl) Check fingerstick blood glucose Every 1 hr if blood glucose outside goal range OR with any s in insulin infusion rate Every 2 hr if 3 consecutive blood glucose measurements between 80 to 110 mg per dl and no in insulin infusion rate during that time period Every 4hr if blood glucose 80 to 110 mg per dl for 24 consecutive hours PRN for signs or symptoms of hypoglycemia Adjust IV insulin per IV insulin chart on page 4 Check potassium every 6 hrs for 24 hours. For interruptions in enteral or parenteral caloric source: 1. Start D5W at 100 ml per hr 2. Check blood glucose in 30 minutes times 2 and continue to follow protocol 3. Call MD For transport out of unit: 1. Discontinue IV insulin 2. Hold tube feeds 3. Start D5W at 100 ml per hr 4. Check a blood glucose prior to transport 5. Check a blood glucose upon return to the unit and start insulin protocol (from initiation phase of the order set) after caloric intake (IVF/tube feeds) has been restarted.
