A Jan. 22 NY Times article on doctors' math errors regarding dosages, online at < http://www.nytimes.com/2008/01/22/health/research/22lab.html >, includes the passage: << [T]he proper treatment was 0.12 milligrams of epinephrine . . .. Half the doctors were given a glass bottle of epinephrine labeled “1 milligram in 1 milliliter solution.” The other half had bottles labeled “1 milliliter of a 1:1000 solution” — exactly the same thing but expressed as a ratio instead of a concentration. In either case, the correct dosage would be 0.12 milliliters of the solution.
Can someone please help me understand why the two solutions described should have the same concentration of epinephrine? I honestly don't get it. --Dan _____________________________________________________________________ "It don't mean a thing if it ain't got that certain je ne sais quoi." --Peter Schickele
