Alternate Name(s):
Humulin-R, Novolin GE Toronto
Classification:
Hormone
Original Date:
June 1996
Revised Date:
July 2022
Indications:
- To maintain normoglycemia
- Adjuvant therapy for hyperkalemia
Administration:
- IV continuous infusion
- SC
Dosage:
- Use only Regular insulin for IV administration
- IV continuous infusion: 0.01 - 0.1 units/kg/hour. Titrate infusion based on blood glucose
- SC: 0.1 - 0.25 units/kg/dose Q4-12h
Management of Non- Oliguric Hyperkalemia in the Newborn Infant:
- Commence insulin continuous infusion (at 0.05-0.1 units/kg/hour) along with IV dextrose (to increase GIR to at least 8.3 mg/kg/min)
- After stabilizing, must gradually reduce insulin and glucose over hours to prevent rebound hypoglycemia and hyperkalemia.
Side Effects:
- CVS: tachycardia
- Endocrine and metabolic: hypoglycemia, hypokalemia
Parameters to Monitor:
- Blood glucose one hour after starting infusion and after any change; Q4h once blood glucose stable
- Electrolytes, urine glucose
- For treatment of hyperkalemia: monitor blood glucose q30- 60 min after commencing therapy, and 2 to 4 hrs after stabilizing blood glucose.
Reconstitution and Stability:
** Prior to connecting IV line to the patient, fill the IV line with the insulin infusion and let it stand 15 to 30 minutes. After 15 - 30 minutes, open the IV and rapidly flush through the line with a minimum of 5 mL of the insulin infusion to prime it. This helps reduce absorption of running insulin by the plastic tubing. If there is no time to let insulin stand in the line, flush line with 20 mL of the insulin infusion over a 1 minute period immediately prior to connecting the tubing to the patient.
