laryngospasm
Pronunciation: luh-RING-go-spazm
Involuntary spasm of the laryngeal muscles causing airway obstruction, particularly common in pediatric patients during anesthesia emergence.
Full Definition
Laryngospasm is a potentially life-threatening complication involving involuntary contraction of the laryngeal muscles, resulting in partial or complete airway obstruction. In pediatric anesthesia, children are at higher risk due to their increased airway reactivity, smaller airway diameter, and higher oxygen consumption. The condition most commonly occurs during light planes of anesthesia, particularly during emergence or with airway irritation from secretions, blood, or surgical manipulation.
Usage
Usage note: Always lowercase unless beginning a sentence. Do not confuse with bronchospasm, which affects the lower airways.
