Dysphagia Final Flashcards
(87 cards)
what are image structures of the upper aerodigestive tract?
oral cavity, velopharynx, pharynx, larynx, PES, and esophagus
why are instrumental exams completed?
assess movement patterns of swallowing related structures in the upper aerodigestive tract to formulate inferences regarding physiologic integrity (speed, symmetry, range, strength, sensation and coordination)
assess effectiveness and safety of swallow, accomodation to varying materials
Identify and describe any airway compromise/pooled secretion/potential other areas and the circumstances in which they occur
evaluate effect of compensatory maneuvers to improve swallowing safety and efficiency
assist in forming clinical recommendations/interventions
to complete an instrumental exam or not?
is there a safe po/nutritional plan?
active concern for aspiration and pulmonary sequelae?
why is there dysphagia?
what is the nature/volume/incidence of aspiration?
tx planning?
radiation exposure?
transportation/access to exam?
tolerating an endoscope?
dysphagia impact on life?
will it effect overall outcome?
patient’s agreement/desire?
medically stable?
medical status still evolving?
Modified Barium Study aka as…
Videofluoroscopic Swallow Study (VFSS)
Barium
used for MBS because it’s sticky, coats surfaces, mixes well w food, if aspirated its not super toxic to lungs
Varibar- more expensive, pre made barium, more standardized
its concentration effects what you see on MBS
pharyngeal recesses
valleculae and pyriform sinuses(2)
if pocketing= oral problem; problem w bolus formation, tongue coordination/motor planning
enlarged pyriform sinuses can be an indication of dysphagia for a long time
testing trials for MBS
Thin liq, Nectar thick, honey thick, pudding, solid (lateral), nectar thick, pudding (A-P)
1mL, 3mL, 5mL, 10mL….20mL is a cup sip
- independent drinking spontaneously?
- straw drinking?
- be comprehensive- drink how you normally would
MBSImp starts with 1oz of thin liq bc aspirating h20 is safe, thicker textures are stickier and if residue on MBS will blur residue of thin liquids and nectar
thin liq= hardest
Interpreting Oral stage of MBS
labial seal- is there anterior spillage? (central, left,right)
lingual bolus control- is there a scattered bolus across tongue, oral cavity, in sulci?
is there impaired/inadequate mastication?
impaired bolus transport - is there a single lingual wave stripping the bolus anterior to posterior oral cavity? is it timely?
oral residue- is there oral residue and if so, where? sulci, lingual surface, scattered? how much residue?
Interpreting Pharyngeal stage of MBS
initiation of pharyngeal phase- where’s the bolus when the hyoid begins to move? (timely swallow- from faucial pillars to passing jaw bone)
velar mvmt/seal- is there air or contrast within vp port (b/t velum and PPW? nasal regurgitation?)
laryngeal excursion- is the larynx elevating? are the arytenoids contracting the epiglottis?
epiglottic deflection- is the epiglottic moving inferiorly, retracting or inverting?
laryngeal vestibule closure- is the vestibule sealed? is there any air or contrast within the vestibule? penetration or apiration?
Interpreting Pharyngeal and Esophageal stage of MBS
pharyngeal stripping and contraction- is there a single stripping wave from superior nasopharynx descending to PES?
PES/UES opening- is there compete opening of PES? does the bolus pass easily thru PES? is there retrograde flow back to pharynx?
tongue base retraction- does the tongue base retract to meet PPW?
pharyngeal residue?
esophageal clearance? retrograde flow?
MBS Rating scales
MBSImp
Penetration Aspiration Scale
DIGEST
DIGEST
based on the pattern of airway entry and pharyngeal residue over a standard set of bolus trials administered in the MBS examination
Fiberoptic Endoscopic Evaluation of Swallowing (FEES)
Langmore et al 1988 first described FEES
required training and proof of competency
state and facility determines IF FEES allowed and WHO can do it (invasive)
strict sterilization and handling procedures per facility
state and facility determine if vasoconstrictor/anesthetizing agent can be used (NYS does not allow SLPs to use spray)
FEESST
pioneered by Dr. Aviv to test sensory function for airway protection as part of FEES exam
uses bursts of air through a port on the endoscope on points in the supraglottic larynx for a reflexive response
discussion of barriers
equipment no longer in production
Pros of FEES
view structures on camera
view airway, edema, TVFs
view secretions and impact
use bedside/mobile unit
SLP schedule based (versus room time in radiology)
Cons of FEES
patient comfort/tolerance
structural changes/contraindications
risk of nose bleed, laryngospasm and/or vasovagal
“white out” period
limited sub-glottic view
FEES procedure
lubricate and pass the endoscope thru the nare
assess velar function and symmetry
advance thru vp port
home view/ birdseye view - observe secretions and characteristics
advancing view if needed - assess and observe laryngeal function / subglottic image
- vary volume and consistency of materials
oral containment- lingual velar seal/premature spillage
whiteout- degree of constriction
residue location, volumes
airway compromise
patient rxn to residue or airway compromise
effect of manuevers and compensations
white food coloring
best bc it reflects light from the scope
up to date most recommended
additional instrumental tests
ultrasound
pulse MRI
CT scan
EMG
high resolution pharyngeal manometry
dysphagia diets
ASHA and NYS do not create guidelines, diets, or endorse any system
traditional diet descriptors
national dysphagia diet (NDD)- discontinued 10/21
international dysphagia diet and standardization initiative (IDDSI)
who can order a diet?
state laws and individual facilities regulate and determine who writes diet orders
SLPs- we comment on texture, can make a pending order with a MD cosign (can be done inNYS), not anymore bc EMR, make recommendation
Registered dietician- makes orders
nutritional restrictions and components of diets
diabetic -NCS
low salt/low sodium- NAS
1800 ADA
low residue diet
renal diet
RD or nutritionist - scope of practice
NPO
nil per os
nothing by mouth
may be recommended by SLP or medically necessarily for testing or procedure
NON-ORAL diets
nasogastric tubes - continuous or bolus feed , can feed duendom (intestine)
gastric tube or jejunostomy tube
parenteral nutrition (always last option)-
- peripheral parenteral nutrition (PPN) - more short term; nutrients directly into bloodstream
- total parenteral nutrition (TPN)- goes into subclavian, if no other options
