Although dosing and sizing of resuscitation drugs and equipment are mostly weight based, time is usually insufficient to weigh critically ill children. Many age-based weight estimation formulae for emergency use have been developed worldwide, but there is no specific formula for Japanese children. The aim of this study was therefore to develop and validate age-based formulae for estimating the bodyweight of children living in Japan. ⋯ The newly developed JAPAN formulae for age-based weight estimation are appropriate for children living in Japan.
