Q

When can an SLP conduct a FEES legally?

A

In collaboration with an MD or if the act has been delegated to them by MD.

23
Q

Pros of FEES

A
  • No radiation exposure
  • Direct view of laryngeal and pharyngeal structures during swallow (vocal fold mobility + airway protection; VP insufficiency)
  • Bedside in typical feeding position
  • Secretion management
  • Visual biofeedback to pt
24
Q

Cons of FEES

A
  • Uncomfortable
  • Can’t view oral/esophageal phase
  • Limited view of pharyngeal phase bc of white out (before and after comparison)
  • Fast successive swallows in infants can be difficult to view
  • Specialized training needed
  • Not good for viewing aspiration, can only suspect it
25
Q

T/F: You can evaluate a pt who is intubated

A

False

26
Q

3 most common causes of solid food dysphagia

A
  • Gastro-esophageal reflux
  • Radiation tx
  • Dysfunction of cricopharyngeus muscle
27
Q

Mechanical/structural etiologies of dysphagia

A
  • Head and neck cancer
  • Cervical spine osteophyte (spurs/growths)
  • Cricopharyngeal bar
  • (Zenker’s) diverticulum
28
Q

Cricopharyngeal bar

A

Appears btwn C3-C6 (someone else needs to confirm)
Thickened muscle from fibrous connective tissue
Often caused by reflux
Causes increased pressure in the pharynx, narrowed opening to the esophagus

29
Q

Zenker’s diverticulum

A

The CP muscle is too strong; pressure build along the pharyngeal wall; the weak point of the throat above caves in

Bc the sphincter is tighter than normal, food enters the diverticulum and causes regurgitation

Difficulty swallowing
Food feeling stuck
Bad breath
Regurgitation
Weight loss
Choking/coughing

30
Q

Commmon dysphagia symptoms post-stroke

A
  • Longer oral + pharyngeal transit time
  • Delayed or absent pharyngeal swallow (holding bolus in mouth bc can’t trigger swallow)
  • Weakness = multiple swallows
31
Q

T/F: Feeding tube is NOT helpful for ppl with dementia

A

True
Alternative - careful hand feeding (comfort - risk of choking/aspiration)

32
Q

Why does radiation worsen dysphagia?

A

Xerostomia
Fibrous soft tissue

33
Q

Cuff inflated –> air goes ___

A

Directly out the stoma

**can cause increased pressure on esophagus and make it harder to swallow

34
Q

Common effects post-extubation (7)

A
  • Trauma to muscles (tube irritating)
  • Dysphagia
  • Stenosis (narrowing of trachea)
  • Disuse atrophy (relearning how to swallow)
  • Mucosal inflammation
  • Temporary VF paralysis (hoarse)
  • Reduced laryngeal sensation
35
Q

Compensatory strategy for premature spillage into pharynx –> delayed initiation of swallow

A

Chin tuck
- Keeps bolus contained within oral cavity until ready to swallow
- Protects airway by narrowing opening (more likely to go into esophagus)

36
Q

Compensatory strategy for penetration/aspiration before swallow (bolus spilling into pharynx) / reduced tongue base retraction

A

Chin tuck
- Increases contact btwn tongue base and PPW
- Protects airway (narrowed opening)
- Keeps bolus contained within oral cavity

37
Q

When would we use the chin up/head tilt back strategy?

A
  • If we know they have good airway protection and just oral dysphagia only
  • Difficulty propelling the bolus during oral transport
  • Facilitates posterior propulsion but often used incorrectly by pts – usually reserved for pretty extreme oral phase impairment
38
Q

When we use head turn towards weaker side?

A
  • Unilateral VF abduction
  • Unilateral pharyngeal weakness/residue accumulation

Turn toward impaired side approximates VFs.
Forces gravity to direct toward stronger side.

39
Q

Describe the supraglottic swallow maneuver and why we would use it

A
  • Breathe in through nose, hold breath, swallow while breath hold, cough, then swallow again

Promotes laryngeal valving prior to swallow; faster closure of VFs during swallow
Prolongs the pharyngeal swallow so the bolus has more time w/ the VFs closed to clear into esophagus

40
Q

Describe the Mendelsohn maneuver and why we would use it

A

Swallow normally and feel Adam’s apple move. Swallow again, once at max height, squeeze muscles and hold for 3 seconds before releasing.

  • Targets the elevation of larynx for a prolonged period
  • Used for pts with a slowed transfer of bolus through pharynx (UES closes before bolus completely transfers) or incomplete UES opening
41
Q

Describe the effortful swallow and why we would use it

A

Tongue against roof of mouth and swallow hard (exaggerate movement)

  • To increase tongue base retraction
  • To increase pharyngeal driving pressure
42
Q

IDDSI levels

A

7 - regular
7 Easy to Chew
6 - soft and bite sized
5 - minced and moist
4 - puree - extremely thick
3 - liquidized - moderately thick
2 - mildly thick
1 - slightly thick
0 - thin

43
Q

Requirements for swallow maneuvers

A
  • Active participation
  • Good movement control
  • Proprioceptive sense
  • Ability to learn
44
Q

Environmental Modifications for dysphagia management

A
  • Reduce distractions so they don’t forget about the food in their mouth
  • Increase cues to help pt awareness (e.g. coloured paper under plate)
  • Rate limiting cup or straw
45
Q

Masako maneuver and why we would use it

A

Protrude tongue between teeth and swallow saliva while biting down.

  • Improves pharyngeal weakness by strengthening contact with base of tongue; PPW bulges forward to meet it
46
Q

Shaker maneuver and why we would use it

A

Lying on the back, elevating head to see one’s toes without moving shoulders

  • Increases UES opening and helps with anterior excursion of larynx
47
Q

When would we recommend EMST?

A

Any patients with weakened cough (e.g. PD, ALS)

More powerful cough to clear aspirated material and improve VF adduction

48
Q

Is pharyngeal residue ever normal?

A

No, healthy person swallows a bolus as a whole unit in a single swallow with no residue

49
Q

Pharyngeal residue may reflect:

A
  • A bolus that is especially thick or sticky
  • Poor tongue strength for propulsion
  • Poor pharyngeal constriction behind the bolus (**strongest link)
  • Problems with diameter or duration of UES opening
50
Q

Patient’s facial nerve VII is damaged. How will this affect their swallow?

A
  • Dry mouth - less saliva
  • Poor lip seal
  • No taste in front 2/3 of tongue
51
Q

Patient’s glossopharyngeal nerve IX is damaged. How will this affect their swallow?

A
  • Inability to trigger pharyngeal phase
  • Diminished or absent cough reflex / gag
  • Reduced pharyngeal dilation
  • Reduced laryngeal elevation
52
Q

Patient’s vagus nerve X is damaged. How will this affect their swallow?

A

Overall difficulty with oral and pharyngeal phase bc innervates soft palate, base of tongue, pharynx.
- Nasal regurgitation
- Reduced or absent gag reflex
- Insufficient laryngeal closure
- Opening of UES segment (so food flowing through before ready?)

53
Q

Patient’s hypoglossal nerve XII is damaged. How will this affect their swallow?

A

Inability to coordinate mvmt of tongue in oral phase; result in pocketing
Insufficient pressure generation to propel bolus
