Design outcomes

Primary

Measure	Time frame
To evaluate and compare whether application of cricoid pressure hampers the placement of ProSeal laryngeal mask airway in anaesthetized and paralyzed adult patientsTimepoint: Cricoid pressure will be applied once at time of placement of Proseal LMA	—

Secondary

Measure	Time frame
To evaluate and compare whether application of cricoid pressure impedes ventilation through the ProSeal laryngeal mask airway in anaesthetized and paralyzed adult patients. 3. To evaluate any adverse effects observed during the study. Timepoint: At time of application of Cricoid pressure	—
