[Dysphagia in Tracheostomized Patients after Long-Term Mechanical Ventilation - Become Sensitive to Reduced
1Neurologisches Rehabilitationszentrum (N1), Brandenburg-Klinik, Bernau.
Abstract:
Independent of the type of critical illness, tracheostomized patients have a high risk of developing a dysphagia. This is potentially life-threatening as it can lead to aspiration and pneumonia. It is therefore essential to perform swallowing diagnostics by means of a bolus dyeing test and/or FEES before oral feeding. Since a physiological airflow through the larynx and adequate subglottic pressure are key components of an effective swallowing act, oralisation should be avoided as far as possible with a blocked tracheal cannula.

Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
Tracheostomy Decannulation
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...
