Eight of the 9 infants had loss of pharyngeal and laryngeal sensitivity leading to delays in initiation of the pharyngeal (or semiautomatic) swallowing phase and evidence that the swallowing reflex
was triggered only when the bolus arrived on pyriform sinuses or the retrocricoid region, a delay that is associated with increased risk of aspiration before swallowing (Figure 2).
2001) 20 concluded that the involvement of the CNS may contribute to the delay in the swallowing reflex
shooting and abnormal EMG EES can identify dysphagia in this disease.
Precipitating factors for foreign body aspiration in the elderly possibly include a depressed mental status, intubation, or impairment in the swallowing reflex
Neuromuscular dysphagia is either a swallowing reflex
problem, a disorder of the pharyngeal and striated esophagus muscles, or an esophageal smooth muscle disorder.
1) The swallowing reflex
also weakens during sleep, which allows aspiration of toxic saliva into the lung.
Then several swallowing reflex
motions occur, including a series of complex throat neuromuscular reactions, which push the bolus into the esophagus.
The etiology of dysphagia after stroke is multifactorial, but one of the most common reasons is motor dysfunction, which includes the absence or delay in the triggering of the swallowing reflex
, cricopharyngeal dysfunctions, reduced lingual control, reduced gag reflex, and reduced strength of pharyngeal contraction (24-26).
Recumbent animals may be bloated, have ruminal stasis or lose their swallowing reflex
She had two heart defects, a cleft palate, and an abnormal swallowing reflex
, which meant she had to be fed through a tube in her nose.
Glycyrrhizin exerts antitussive effect by stimulating salivation and inducing a more frequent swallowing reflex
The swallowing reflex
may be diminished and aspiration of food down the trachea may occur.
