The effect of LPR in the pediatric airway might be mediated by one or all of three mechanisms: (1) microaspiration with stimulation of the laryngeal adductor reflux, (2) micro-aspiration with chemical pneumonitis, and (3) stimulation of an esophageal-vagal and/or autonomic reflex that results in or potentiates bronchial constriction.
