Weight-based Calculations

Importance of Weight-based Calculations in Paediatrics

• In paediatrics, weight-based calculations are crucial to ensure accurate medication dosing, as children's weights vary greatly.
• Weight-based calculations help to minimize the risk of medication errors and adverse effects.

Factors to Consider

• Weight units: Ensure that the weight is in the correct units (e.g., kg, g, lb) to avoid calculation errors.
• Dose units: Verify that the dose units match the weight units (e.g., mg/kg, mcg/kg).

Formula for Weight-based Calculations

• Dose (mg) = Dose (mg/kg) x Weight (kg)
• Dose (mcg) = Dose (mcg/kg) x Weight (kg)

Examples of Weight-based Calculations

• A child weighing 10 kg requires a medication dose of 5 mg/kg. Calculate the dose in mg:
  • Dose (mg) = 5 mg/kg x 10 kg = 50 mg
• A child weighing 5 kg requires a medication dose of 2 mcg/kg. Calculate the dose in mcg:
  • Dose (mcg) = 2 mcg/kg x 5 kg = 10 mcg

Tips for Accurate Calculations

• Always use the correct weight and dose units.
• Verify calculations before administering medication.
• Consider using a paediatric dose calculation formula sheet or a calculator to minimize errors.

Examples of Weight-based Calculations

• For a 10 kg child, a 5 mg/kg medication dose is calculated as: Dose (mg) = 5 mg/kg x 10 kg = 50 mg
• For a 5 kg child, a 2 mcg/kg medication dose is calculated as: Dose (mcg) = 2 mcg/kg x 5 kg = 10 mcg
