A New Insertion Technique for Laryngeal Mask Airway
In Brief
A clinical study evaluating Group 1 Classic, Group 2 pre-inflated, and 1 other intervention for Airway Morbidity. Completed, enrolled 450 participants across 1 site.
Detailed Summary
A laryngeal mask airway ("LMA") is an airway device that is commonly used and placed under general anesthesia to facilitate ventilation of the patient's lungs while anesthetized. It is similar to an "endotracheal tube" (a breathing tube) but is less invasive. It is also placed as a backup when the Anesthesiologist is unable to pass a breathing tube and the patient is not adequately ventilating. Unfortunately, an LMA may lead to complications similar to those of breathing tube placement, such as sore throat and hoarse voice. Previous studies have examined several variables that may affect how often complications occur; these variables include giving anti-inflammatory medications and inflating the LMA to different pressures (the "working" end of the LMA, which rests in the patient's throat, has a cuff that is inflated to provide a seal). We are studying the effect of the PLACEMENT TECHNIQUE on postoperative sore throat, hoarse voice, and difficulty swallowing. We will be using 3 placement techniques - the traditional placement technique, a slightly different traditional placement technique, and a new technique, abbreviated the "ELLIA" method. The hypothesis of this study is that a new LMA insertion technique will have no difference in postoperative pharyngolaryngeal morbidity including sore throat, dysphagia and dysphonia.

Timeline
Interventions
Active Comparator: Group 1 classic Group 1 Using the classic inserting technique and completely deflated LMA recommended in the LMA manual.
Group 2 (pre-inflated): Using the recommended inserting technique with the pre-inflated volume that exists in a LMA (Laryngeal Mask Airway) from the manufacturer.
Group 3 (ELL-PIC): Using the ELL-PIC technique
