Details and patient eligibility

About

The aim of this study is to compare the effect of paratracheal and cricoid pressure on LMA ProSeal insertion, insertion time, insertion difficulty, and the rate of optimal positioning of the device after insertion.

Enrollment: 80 patients

Sex: All

Ages: 18 to 70 years old

Volunteers: No Healthy Volunteers
