We have compared four tests for assessing airway sealing pressure with the
laryngeal mask airway (LMA) to test the hypothesis that airway sealing
pressure and inter-observer reliability differ between tests. We studied 80
paralysed, anaesthetized adult patients. Four different airway sealing
pressure tests were performed in random order on each patient by two
observers blinded to each other's measurements: test 1 involved detection
of an audible noise; test 2 was detection of end- tidal carbon dioxide in
the oral cavity; test 3 was observation of the aneroid manometer dial as
the pressure increased to note the airway pressure at which the dial
reached stability; and test 4 was detection of an audible noise by neck
auscultation. Mean airway sealing pressure ranged from 19.5 to 21.3 cm H2O
and intra-class correlation coefficient was 0.95-0.99. Inter-observer
reliability of all tests was classed as excellent. The manometric stability
test had a higher mean airway sealing pressure (P < 0.0001) and better
inter-observer reliability (P < 0.0001) compared with the three other
tests. We conclude that for clinical purposes all four tests are excellent,
but that the manometric stability test may be more appropriate for
researchers comparing airway sealing pressures.
