Infantile laryngospasm

Pediatric laryngospasm refers to the persistent contraction of the laryngeal muscles in children, where the vocal cords (organs used for phonation) adduct inwards, and the glottis (the part through which airflow passes) partially or completely closes, leading to varying degrees of respiratory distress. This condition is more common in children aged 2-3 years, with a higher incidence in boys than girls. The main symptoms include cyanosis or pallor of the child's face, restless movements of hands and feet, cold sweats, difficulty breathing, cyanosis of the lips, resembling suffocation. These symptoms may be relieved after deep breathing, and there are no abnormalities in the throat.
