Management of Dysphagia

Introduction to Dysphagia Management

The management of dysphagia should include a combination of optimization of dopaminergic medication, expiratory muscle strength training (EMST), effortful swallowing exercises, and postural modifications, along with adaptations in food and liquid consistency, as recommended by clinical guidelines 1

Initial screening for dysphagia should be performed as soon as a neurological condition is diagnosed, with comprehensive assessment including bedside evaluation and instrumental examination when clinically indicated (videofluoroscopy or FEES) 2
Patients who fail initial screening should receive nothing by mouth until a comprehensive assessment is completed, preferably within three days of diagnosis, including bedside evaluation, instrumental examination when clinically indicated, and consideration of patient-specific factors (e.g., dental status, cognitive deficits) 2
The 3-oz water swallow test is an accurate predictor of a patient's ability to tolerate thin liquids, though not their overall ability to eat by mouth 2

Expiratory muscle strength training (EMST) has demonstrated significant effects on swallowing safety in patients with dysphagia, and consists of rapid and forceful exhalation into a one-way valve mouthpiece 1
Effortful swallowing is indicated for patients with significant residue in the valleculae and/or pyriform sinuses, and increases hyolaryngeal excursion and lingual pressure 1
The Shaker technique (head lift) is designed for patients with suprahypoid muscle weakness, and improves the strength and endurance of the suprahypoid muscles and the opening of the upper esophageal sphincter 1
The chin-down technique is recommended for patients with inadequate airway protection, reduces the risk of aspiration by approximately 50%, and expands the vallecular spaces and approximates the base of the tongue to the pharyngeal wall 1
Head rotation is indicated specifically for cases with hypertonicity, incomplete release, or premature UES closure, to improve swallowing safety and reduce aspiration risk 1
Hyperextended head posture is only indicated in the absence of lingual pump and when safe transit is ensured, to prevent aspiration and ensure safe swallowing 1

Adapt food texture to compensate for poor oral preparation and ease transport, using soft, semisolid, or semiliquid textures, particularly for patients with delayed swallowing who may benefit from thicker liquids and semisolid foods with high water content 1
Fractionate meals into smaller portions for patients with muscle fatigue, and enrich meals with energy or deficient nutrients to prevent malnutrition 1
Consider oral nutritional supplementation if weight loss progresses, to ensure adequate nutrition and prevent further complications 1
Ensuring adequate nutritional support is crucial to prevent malnutrition in patients with progressive dysphagia, as recommended by the European Society for Medical Oncology 3

Hospitalized patients with dysphagia typically consume less fluid than recommended, highlighting the need for careful monitoring and intervention 4
Monitor fluid balance carefully, especially for patients receiving thickened fluids, and consider free water protocols (allowing water between meals) alongside thickened liquids to increase overall fluid intake while maintaining safety 4
Opioids should not be prescribed for pain management in patients with progressive dysphagia due to their potential to worsen dysphagia and increase aspiration risk, as recommended by the American Gastroenterological Association 5
Neuromodulators, such as tricyclic antidepressants (TCAs) and selective serotonin-norepinephrine reuptake inhibitors (SNRIs), can be used to manage pain in patients with progressive dysphagia, with limited evidence supporting their effectiveness 5
ACE inhibitors may potentially reduce aspiration risk by preventing breakdown of substance P, which plays a role in cough and swallow sensory pathways, although further research is needed to confirm this effect 6

Surgical intervention, such as cricopharyngeal myotomy, is recommended for intractable aspiration cases, particularly for specific conditions like pharyngeal/cricopharyngeal strictures, oropharyngeal tumors, posterior pharyngeal diverticulum, and cervical webs, although it is not suitable for neurologic insult 6
The American College of Chest Physicians indicates that surgical intervention should be considered for patients with severe dysphagia who have not responded to conservative management, and who have a high risk of aspiration pneumonia 6

Regular reassessment is crucial as dysphagia can change over time, especially with progressive conditions, and treatment must be adjusted accordingly to ensure optimal management and prevent complications 1
Instrumental assessment is essential, as clinical assessment alone may miss silent aspiration, and regular monitoring is necessary to adjust treatment and prevent further complications 1
A clinical swallowing examination or instrumental swallowing evaluation (VFSS or FEES) is necessary to identify specific swallowing abnormalities and reassess treatment effectiveness 1
Monitoring for signs of aspiration pneumonia, malnutrition, weight loss, dehydration, and medication intake difficulties is crucial to prevent complications 1
Early implementation of swallowing rehabilitation can improve patient outcomes, with limited evidence supporting its effectiveness 7
