LMA
Also written as: LMA — Laryngeal Mask Airway
Laryngeal Mask Airway - a supraglottic airway device commonly used in pediatric anesthesia as an alternative to endotracheal intubation for routine procedures.
Full Definition
The Laryngeal Mask Airway (LMA) is a supraglottic airway device that sits above the larynx, providing a seal around the laryngeal inlet without entering the trachea. In pediatric anesthesia, LMAs offer several advantages over endotracheal tubes, including easier insertion, reduced airway trauma, and lower incidence of sore throat and cough. They are particularly useful for spontaneously breathing patients undergoing procedures where muscle relaxation is not required. Pediatric-specific designs accommodate the unique anatomical features of children's airways, including relatively larger tongues and more anterior larynges.
Usage
Usage note: LMA is both the acronym and the trademarked brand name. Use 'laryngeal mask airway' for generic references.
