LMA Cuff Pressure and LMA-induced Complications

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

• Status: Completed
• Phase: —
• Study type: Observational
• Enrollment: 360 (actual)
• Sponsor: Mayo Clinic · Academic / Other
• Sex: All
• Age: 18 Years – 99 Years
• Healthy volunteers: Not accepted

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..

Conditions

• Sore Throat
• Dysphagia
• Dysphonia

Interventions

Type	Name	Description
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.
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
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.
