Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Investigators aim to compare two supraglottic airway devices; the i-gel and the newly developed laryngeal mask airway protector in terms of airway sealing effect, the insertion success rate, and the incidence of complications in anesthetized patients.
