儿童用药剂量计算法通常分为年龄折算法,体重计算法和体表面积计算法。工作临床实际中以体重计算法应用最多。将这3种计算法所得数值比较一下则可看出差别较大。如患儿1岁,体重10kg,身高62cm,使用成人量1.0g 的药物其剂量分别为:折算法:1.0×1/5=0.2g,体重法:10×1/(60)=0.166g,体表法:1.0×(0.45)/(1.7)=0.27g(体表法因所用计算公式不同仍稍有差别)从计算结果可见,体表法最高,体重法最低。根据临床治疗效果看,大多认为以体表法计算更为合适。但由于该法计算麻烦, Children’s medication dose calculation method is usually divided into ages, weight calculation and body surface area calculation. Clinical practice of weight calculation method used most. Comparing the values ​​of these three kinds of calculation methods, we can see that there is a big difference. If the children 1 year old, body weight 10kg, height 62cm, the dosage of the drug 1.0g adult use method are: conversion method: 1.0 × 1/5 = 0.2g, body weight method: 10 × 1 / (60) = 0.166g, Body surface method: 1.0 × (0.45) / (1.7) = 0.27g (body surface method is still slightly different due to the use of different formula) can be seen from the calculation results, the highest body surface method, the lowest weight method. According to the clinical treatment effect, most think that the body surface method is more appropriate. However, due to the method of calculating trouble,
