Brief summary
The laryngeal mask airway (LMA) supreme is a relatively new single-use supraglottic airway with modification. The parameters about airway sealing such as oropharyngeal leak pressure (OLP) and leakage volume are important markers of efficacy and safety when using the supraglottic airway. The airway sealing is related to the intracuff pressure of laryngeal mask airway. The aim of this study is to compare the airway sealing of the LMA supreme at various intracuff pressure in children.
Interventions
PROCEDUREintracuff pressure by cuff pressure manometer
36 patients are randomly allocated according to random sequence of the intracuff pressure 40, 60 and 80 cmH2O. After insertion of LMA supreme, we confirm adequate ventilation. And then we measure OLP and leakage volume at intra-cuff pressure 40, 60 and 80 cmH2O adjusted by cuff pressure manometer according to random sequence of the intracuff pressure.
