Discussion:
Oral airway sizing is an effective method for
choosing the correct SLMA size, and is a
measurement already familiar to most anesthesia
practitioners. The up-down maneuver improved
SLMA fit in 27% of the patients. This maneuver is
performed with the ILMA and CTrach to reposition
a down-folded epiglottis, and may also work
similarly with the SLMA. Further studies to confirm
this maneuver’s efficacy with the SLMA are needed.
