The effect of changing the sequence of cuff inflation and device fixation with the LMA-Supreme® on device position ventilatory complications and airway morbidity: a clinical and fiberscopic study

摘要

BackgroundThe conventional sequence when using supraglottic airway devices is insertion, cuff inflation and fixation. Our hypothesis was that a tighter fit of the cuff and tip could be achieved with a consequently lower incidence of air leak, better separation of gastrointestinal and respiratory tracts and less airway morbidity if the device were first affixed and the cuff then inflated.
