Calcium Infusion Guidelines
Indications and Administration
- Early neonatal hypocalcemia due to interruption of placental transfer and relative immaturity of hormonal control may be treated with calcium infusion 1
- Calcium channel blocker toxicity with hemodynamic instability may be treated with calcium infusion, with a recommended dose of 20 mg/kg (0.2 mL/kg) of 10% calcium chloride intravenously over 5-10 minutes 2, 3
- Beta-blocker overdose with shock refractory to other measures may be treated with calcium infusion, with a recommended dose of 0.3 mEq/kg of calcium (0.6 mL/kg of 10% calcium gluconate or 0.2 mL/kg of 10% calcium chloride) IV over 5-10 minutes 4, 5
- Hypermagnesemia with cardiotoxicity or cardiac arrest may be treated with calcium infusion, with a recommended dose of 5-10 mL of 10% calcium chloride or 15-30 mL of 10% calcium gluconate IV over 2-5 minutes 6
- Hyperkalemia with cardiac manifestations may be treated with calcium infusion 3
Monitoring and Precautions
- Serum ionized calcium concentration should be monitored to prevent hypercalcemia during calcium infusion 2, 7
- Heart rate should be monitored during administration, and the injection should be stopped if symptomatic bradycardia occurs 3
- Calcium infusion should not be mixed with sodium bicarbonate or vasoactive amines 3
- Calcium chloride provides a more rapid increase in ionized calcium than calcium gluconate and is preferred for critically ill patients 3
