A laryngeal mask airway is a supraglottic airway device which allows for controlled ventilation and delivery of anesthetic gases without requiring laryngoscopy or instrumentation of the trachea. It is considered to be a less secure airway device than an endotracheal tube.
LMA® Supreme™ Airway is advertised to increase efficacy and safety versus first-generation devices including decreased aspiration risk.
Features include:
- Compared to traditional LMA, LMA supreme has a curved rigid airway shape
- Elongated cuff to help with smooth insertion
- Distal tip with laryngeal and esophageal seals
- Integrated bite block
- Tab to help with securing device
- Additional channel to allow for insertion of oral-gastric tube insertion to decompress stomach
- however, it does not provide a protected airway as a cuffed endotracheal tube would
