LMA Cuff Pressure and LMA-induced Complications

November 5, 2015 updated by: Christopher B. Robards, Mayo Clinic

Using the Natural Recoil of the Inflating Syringe as a Safety Valve to Limit LMA Cuff Pressure and Decrease LMA-Induced Complications

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..

Design Details

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Standard Practice
Device: Standard 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.
Other Names:
  • LMA inflation routine clinical practice
Syringe recoil
Device: Pressure 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
Other Names:
  • LMA cuff pressure by syringe recoil
Pressure Transducer
Device: Pressure 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.
Other Names:
  • LMA cuff pressure checked by pressure transducer

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Time Frame
Pressure of the syringe after inflation of the LMA cuff
Time Frame: after inflation, 1 hour into surgery
after inflation, 1 hour into surgery

Secondary Outcome Measures

Outcome Measure
Time Frame
Number of patients with dysphagia and/or dysphonia
Time Frame: 1, 2, and 24 hours after surgery
1, 2, and 24 hours after surgery
