IV Fluid Rate for 14kg Pediatric Patient

For a 14kg child, the maintenance IV fluid rate is 52 mL/hour using the standard 4-2-1 rule (also known as the Holliday-Segar method).

Calculation Method

The calculation follows this stepwise approach:

  • First 10 kg: 4 mL/kg/hour = 40 mL/hour 1
  • Second 10 kg (or remaining 4 kg in this case): 2 mL/kg/hour = 8 mL/hour 1
  • Total rate: 40 + 8 = 52 mL/hour 1

Important Clinical Considerations

Fluid Composition

  • Isotonic balanced solutions with approximately 4 mmol/L potassium are recommended for maintenance IV fluids in pediatric patients 2
  • Glucose provision (4-10%) should be included with potassium supplementation, guided by at least daily blood glucose monitoring 2

Monitoring Requirements

  • Serum potassium levels should be measured at minimum daily during continuous IV maintenance fluid therapy 2
  • Glucose, sodium, and potassium levels require careful monitoring during continuous infusion 3

Common Pitfalls to Avoid

  • Do not use adult dosing formulas for pediatric patients, as children require individualized dosing based on age, size, and organ maturity 4
  • Avoid hyperglycemia above 145 mg/dL in pediatric patients, as this is associated with increased morbidity and mortality 3
  • Monitor peripheral IV sites closely when administering continuous infusions, though infiltration rates are low (2%) in monitored settings 5
  • Ensure appropriate electrolyte supplementation is added to continuous infusions to prevent electrolyte imbalances 3
