Review your child’s After Visit Summary before you leave the hospital.  You will need to know:

How should I restart my child’s insulin pump?

1. Make sure the insulin pump is working.  If your child was treated for diabetic ketoacidosis (DKA), you must call the insulin pump support line to see if your pump is safe to use. The insulin pump support line phone number is on the back of your child’s insulin pump.
2. Insert a new pump set in a lump free place on the skin. Refill the insulin pump with fresh insulin.   
3. If your child was given a long-acting insulin like Lantus, set a temporary basal rate on your child’s insulin pump.  Run the temporary basal rate for a full 24 hours from the time the long-acting insulin was given. For example, if your child received a long-acting insulin at 5:00 pm, a temporary basal rate will be used until 5:00 pm the next day. See your child’s AVS for more instructions. 
4. Start the pump to begin giving insulin. 
5. Test the blood sugar or check the Continuous Glucose Monitoring (CGM) device for a current blood sugar level as soon as you start the pump. 
6. Your child’s pump settings may need to be changed.  This will be based on your child’s blood sugar. See your child’s AVS for more instructions. 
7. If your child’s blood sugar stays above 200 mg/dL after 2 hours on the insulin pump, you will need to follow your child’s sick day guidelines. The sick day chart is on the Children’s website diabetes specialty page.  You can ask your care team for one.
