The statistics indicates that the constitution of children, which includes height and body weight, has developed during the last 40 years.Therefore, we investigated that body surface area of children at present for every age which was calculated with Fujimoto's formula was greater than that in 1948.So we reexamined pediatric dose obtained from Augsberger's I, Augsberger's II, Young's, and Fujimoto's formula.The pediatric dose ratio based on body surface area in 1948 much more corresponded with the dose ratio obtained from the Augsberger's II formula.On the other hand, the pediatric dose ratio based on body surface area for every age in 1987 was shifted to higher dose ratio compared with that obtained from the Augsberger's II formula. The pediatric dose ratios obtained from three formulas except Fujimoto's formula indicated lower dose ratio than that obtained from Fujimoto's formula.Furthermore, under the age of five, pediatric dose ratio calculated from Fujimoto's formula was higher than that calculated from Du Bois's formula.The difference between the two dose ratios was larger as the age of children was lower.Consequently, considering big change in the constitution of children during the last 40 years, there may be a possibility to estimate lower pediatric dose than the dose which was required in the present children, if the pediatric dose was eviluated with Augsberger's II formula.
