A search of Medline (1950–June 2013), EMBASE (1980–June
2013) and CINAHL (1981–June 2013) databases was undertaken
using the NHS Evidence Interface. The search terms ‘cyanide’
plus ‘smoke inhalation’, and also ‘cyanide’ plus either
‘hydroxycobalamin’, ‘sodium thiosulphate’, ‘nitrite’, or ‘dicobalt
edetate’ were used.
