For many drugs, it is important to adjust the dose for individual patients. To estimate the dose, a patient's body weight or body surface area (BSA) is often used. BSA is difficult to measure directly, but may be calculated using formulae involving the patient's weight and height. Here we discuss BSA and when it is used in practice, in particular, for calculating drug doses in children and for cancer chemotherapy.
对于许多药物来说，根据个体患者调整剂量很重要。为了估算剂量，常常会用到患者的体重或体表面积（BSA）。体表面积很难直接测量，但可以通过涉及患者体重和身高的公式来计算。在此我们讨论体表面积以及它在实际中的应用，特别是在计算儿童药物剂量和癌症化疗方面的应用。
