purpose of the rule of nines when treating burn victims
Wallace rule of nines The Wallace rule of nines is a tool used in pre-hospital and emergency medicine to estimate the total body surface area (BSA) affected by a burn. In addition to determining burn severity, the measurement of burn surface area is important for estimating patients' fluid requirements and determining hospital admission criteria.[1]
The whole nine yards The Oxford English Dictionary finds the earliest published non-idiomatic use in an 1855 Indiana newspaper article. The earliest known idiomatic use of the phrase is from 1907 in southern Indiana. The phrase is related to the expression the whole six yards, used around the same time in Kentucky and South Carolina. Both phrases are variations on the whole ball of wax, first recorded in the 1880s.[3] They are part of a family of expressions in which an odd-sounding item, such as enchilada, shooting match, shebang or hog, is substituted for ball of wax.[3] The choice of the number nine may be related to the expression "To the nines" (to perfection).[nb 1]
