We conducted a postal questionnaire to survey methods of laryngoscope clean
ing in units throughout Great Britain. We found that there was great variat
ion in practice. Most units autoclave laryngoscope: blades at some time, bu
t less than one-quarter do so between each case. A nide range of methods is
used to clean the blade in units where autoclaving was not undertaken. Mos
t units had no guidelines relating to laryngoscope treatment between uses.
