overinflation of LMAs
Brief summary
The purpose of this study is to determine if using 20 mL B.Braun syringes to inflate LMAs and allowing them to recoil will put the pressure of the LMA cuff within the safety range. It will also determine if remaining within this safety range has an effect on complications after surgery..
Interventions
DEVICEStandard inflation of LMA cuff
LMA cuff will be inflated per standard practice with a syringe and resulting cuff pressure will be measured by manual palpation of the cuff per standard practice.
DEVICEPressure check with syringe recoil
LMA cuff will be inflated per standard practice with a syringe and resulting cuff pressure will be measured by syringe recoil
DEVICEPressure check by pressure transducer
LMA cuff will be inflated per standard practice with a syringe and resulting cuff pressure will be measured by pressure transducer.
