Calcium Chloride Use in Pediatric Patients

Indications and Contraindications

  • The American Heart Association recommends against the routine use of calcium chloride in pediatric cardiac arrest, except in specific life-threatening conditions such as documented hypocalcemia, hyperkalemia, hypermagnesemia, and calcium channel blocker toxicity 1, 2, 3, 4
  • Routine administration of calcium during pediatric cardiopulmonary arrest is not recommended and may cause harm, with a Class III: Harm recommendation and B-NR level of evidence 1, 2, 3, 4

Dosage and Administration

  • For symptomatic hyperkalemia with ECG changes, the American Academy of Pediatrics recommends giving 100-200 mg/kg/dose of calcium chloride via slow infusion with continuous ECG monitoring 9
  • The American Academy of Pediatrics suggests administering 20 mg/kg (0.2 mL/kg of 10% calcium chloride) IV/IO by slow push during cardiac arrest for life-threatening hyperkalemia, hypermagnesemia, and calcium channel blocker toxicity 6, 7, 8
  • For non-arrest calcium channel blocker poisoning, the American Heart Association recommends infusing calcium chloride over 5-10 minutes, followed by continuous infusion of 20-50 mg/kg per hour 12

Critical Administration Considerations

  • The American Academy of Pediatrics prefers central venous catheter administration of calcium chloride and recommends continuous ECG monitoring during administration 6, 7, 8
  • The American Heart Association advises against administering calcium and sodium bicarbonate through the same IV line due to the risk of precipitation 6, 7, 8, 9, 10

Important Clinical Pitfalls

  • The American Academy of Pediatrics warns against confusing calcium chloride with calcium gluconate dosing, as they are not equivalent on a mg-per-mg basis 6, 7, 8
  • The Journal of Clinical Oncology recommends considering renal consultation before calcium administration in tumor lysis syndrome with hyperphosphatemia to avoid calcium phosphate precipitation and obstructive uropathy 9, 10
