LMA Cuff Pressure and LMA-induced Complications
Completed
- Conditions
- Sore ThroatDysphoniaDysphagia
- Interventions
- Device: Pressure check by pressure transducerDevice: Standard inflation of LMA cuffDevice: Pressure check with syringe recoil
- Registration Number
- NCT01385969
- Lead Sponsor
- Mayo Clinic
- 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..
