The first stage involved supplementary cleaning of 70 1\u2003\u00d7\u20031\u2003cm segments from deliberately contaminated laryngeal mask airways using potassium permanganate at 0, 2, 4, 8, 16, 32 and 64\u2003mg.l\n                    <jats:sup>\u22121<\/jats:sup>\n                    and testing for protein staining.

The second stage involved supplementary cleaning of 50 used laryngeal mask airways with either potassium permanganate 8\u2003mg.l\n                    <jats:sup>\u22121<\/jats:sup>\n                    or saline and testing for protein staining. This showed that protein contamination was lower in the potassium permanganate group (p\u2003\n                    <jats:italic>&lt;<\/jats:italic>\n                    \u20030.00001): all laryngeal mask airways in the control group and none in the potassium permanganate group were contaminated. The third stage involved scanning electron microscopic examination of 1\u2003\u00d7\u20031\u2003cm segments from three laryngeal mask airways used in the control group, three from the potassium permanganate group, plus three brand new laryngeal mask airways. The mean density of \u22651\u2003\u03bcm surface particles was lower in the potassium permanganate 8\u2003mg.l\n                    <jats:sup>\u22121<\/jats:sup>\n                    than the control group (21 vs. 121\u2003.cm\n                    <jats:sup>\u22122<\/jats:sup>\n                    , p\u2003&lt;\u20030.0001) and was similar to brand new laryngeal mask airways (24\u2003.cm\n                    <jats:sup>\u22122<\/jats:sup>\n                    ).
