LMA Cuff Pressure and LMA-induced Complications

Mayo Clinic360 enrolled

Overview

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..

Study Type

OBSERVATIONAL

Enrollment

360

Conditions

Sore Throat Dysphagia Dysphonia

Interventions

Standard inflation of LMA cuffDEVICE

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.

Pressure check with syringe recoilDEVICE

LMA cuff will be inflated per standard practice with a syringe and resulting cuff pressure will be measured by syringe recoil

Pressure check by pressure transducerDEVICE

LMA cuff will be inflated per standard practice with a syringe and resulting cuff pressure will be measured by pressure transducer.
