A. DOSE CALCULATION RELATED TO AGE 1. Young`s rule π΄ππ (π¦πππ) πΆππππ`π πππ π = Γ πππ’ππ‘ πππ π π΄ππ π¦πππ + 12 2. Dilling`s rule πππππ`π πππ π =
π΄ππ (π¦πππ) Γ πππ’ππ‘ πππ π 20
3. Fried`s rule πΆππππ`π πππ π =
π΄ππ (ππππ‘π) Γ πππ’ππ‘ πππ π 150

*An average adult`s of 70kg, 175cm has a body surface area of 1.85m2. Child`s body surface area obtained from nomogram that determine body surface area using the height (cm or in) and weight (kg or lb) of the child.
