Lecture 3
Age Related Changes: Geriatric
Aging: Physiologic Impact Vertebral column thinning Lung ossification Cervical osteophytes Larngoptosis TMJ ossification Delayed oral stimulation identification Xerostomia Dentition loss Decreased swallow rates Increased relaxation time of the cricopharyngeus Longer airway closure time Posterior positioning of the bolus Delayed initiation Delayed transit through the phrynx
Respiration during the Swallow
Normal respiratory sequence• Inspiration
• Velum lowers so that breathing can continue during mastication
• Exhalation begins
• Apnea during the swallow
• Exhalation is completed
Triad of Symptoms
Respiratory compromise Dysphagia Protein-calorie malnutrition
• Anyone of these symptoms can contribute to the triad
• The physiology of aging contributes to the probability that anyone of these symptoms could occur.
Saliva
Important functions of saliva• Increase taste perception
• Decreased bacteria
• Maintains acid levels in the stomach
• Facilitates food breakdown Xerostomia
• Dryness of the mouth, pharynx
• Can significantly contribute to dysphagia symptoms
Esophageal Symptoms
Gastroesophageal reflux disease (GERD)• Can exacerbate
• Asthma
• COPD
• Apnea
• Bradycardia
• Hypotension
• Globus sensation (feels like lump in throat)
• Can cause pharyngeal, even oral phase problems.
Differential Diagnosis
Dementia• Cognitive
• Anorexia• Immobility
Neurologic• Sudden onset
• Liquids more difficult than solids Progressive obstructive
• Mechanical problem
• Solids more difficult than liquids
Onset of Symptoms
Sudden Slow-progressive Decompensation
• Short-term
• UTI
• URI
• Dehydration
• Changes in medication
Oral Candidiasis Fungal infection-Thrush Systemic
• Antibiotics• Xerostomia• Immunosuppressed• Chronic disease• Malnourished
Local• Dentures
• Ill fitting• Poor hygiene• overwear
Treatment
Dependent on etiology• Dementia
• Neurologic
• Progressive obstructive Dietary management Surgical Enteral feedings Time-frame Follow-up Mealtime observation
