Suppression of the gag reflex

Suppression of the gag reflex refers to the temporary, intentional inhibition or blunting of the protective pharyngeal reflex, primarily indicated to facilitate diagnostic, therapeutic, or surgical interventions involving the upper aerodigestive tract Pathophysiologically, the normal gag reflex is an involuntary neuromuscular defense mechanism mediated by afferent fibers of the glossopharyngeal nerve (cranial nerve IX) and efferent motor pathways of the vagus nerve (cranial nerve X), which trigg...

Pathophysiologically, the normal gag reflex is an involuntary neuromuscular defense mechanism mediated by afferent fibers of the glossopharyngeal nerve (cranial nerve IX) and efferent motor pathways of the vagus nerve (cranial nerve X), which trigger bilateral pharyngeal muscle contraction and soft palate elevation upon mucosal stimulation Suppression halts this reflex arc, eliminating retching and laryngopharyngeal spasms to optimize airway instrumentation and prevent procedural trauma or aspir...
