Overview

This study aims to investigate whether the use of a video LMA device (SacoVLM™) will facilitate successful supraglottic airway device (SAD) insertion compared to the use of a conventional 2nd generation SAD (Ambu®Auragain™) in elderly patients. This study is a randomized trail with a 50% probability of being assigned to either group. Randomization will be done by an anesthesiologist not involved in anesthesia or postoperative outcome assessment. Patients and the investigator in charge of postoperative outcomes assessment will be blinded to group allocation.

Eligibility

Inclusion Criteria:

        Adult patients 65 years of age or older, ASA class I~III, scheduled for elective surgery
        under general anesthesia under 2 hours, and eligible for SAD use for airway maintenance.
        Exclusion Criteria:
        Refusal to participate, patients unable to read consent form, anticipated difficulty in
        face mask ventilation or airway management based on past history or anatomical structure,
        upper respiratory tract infection, airway-related diseases such as asthma or pneumonia,
        risk of gastroesophageal reflux
