- Treatment/ prevention of hypocalcemia
- IV Direct * :
- in life threatening situation only: over 1 minute
- in cardiac arrest: may give over 10-20 seconds
- IV intermittent infusion *: for symptomatic hypocalcemia: over 30 - 60 minutes
- IV continuous infusion: for maintenance
* Central line preferred
- Life threatening situation: 60 - 100 mg/kg/dose of calcium gluconate 10% (0.6 to 1 mL/kg/dose of calcium gluconate 10% undiluted)
- Symptomatic hypocalcemia: 50 - 200 mg/kg/dose of calcium gluconate (diluted to 50 mg/mL - see reconstitution and stability)
- Maintenance: 0.5 to 1.5 mmol/kg/day of elemental calcium
- 10 mmol/L (0.01 mmol/mL) of elemental calcium at a TFI of 60 to 140 mL/kg/day will provide 0.6 to 1.4 mmol/kg/day of elemental calcium
- 16 mmol/L (0.016 mmol/mL) of elemental calcium at a TFI of 60 to 140 mL/kg/day will provide 1 to 2.2 mmol/kg/day of elemental calcium
- For exchange blood transfusion in the newborn: calcium gluconate diluted to 50 mg/mL - Take 1 mL (100 mg) and add to 1 mL of D5W for a final concentration of 50 mg/mL. Administer 100 mg (2 mL) over 1 minute as a slow bolus in pulses during the procedure for every 100 mL of blood transfused
- CVS: bradycardia with rapid administration
- Miscellaneous: tissue necrosis with extravasation
- HR
- Injection site
- Calcium levels
- IV intermittent infusion:
