RT Journal Article SR Electronic T1 A novel tool to aid usability of age-based weight estimation formulae JF BMJ Innovations JO BMJ Innov FD All India Institute of Medical Sciences SP 96 OP 98 DO 10.1136/bmjinnov-2015-000059 VO 1 IS 3 A1 Dilshad Marikar YR 2015 UL http://innovations.bmj.com/content/1/3/96.abstract AB Age-based weight estimation methods are used in the resuscitation of children deemed too sick to weigh. Some methods involve multiple formulae, which can be difficult to recall and use. This paper presents a conceptually simple finger-counting method that can be used to rapidly estimate weight based on existing age-based formulae.
