Q

Fiberoptic Endoscopic Evaluation of Swallowing

A
  • FEES
    1. Used to examine the pharyngeal swallow initially in l988
    2. Used as an alternative when MBS was not available
    3. Widely used today
    4. A FEES is not a screening tool.
    5. A FEES is a 3-D evaluation by SLP’s of:
    a. Anatomy & physiology of the pharynx & larynx
    b. Swallow function
    c. Postural, dietary and behavioral strategies.
    6. FEES is not a duplicate of fluoroscopy but can reveal some unique findings and may be the preferred examination for a patient with dysphagia.

Q

2 Components of FEES training

A
  1. Knowledge based
  2. Hands on practice- 10 normal subjects and 15 abnormal subjects

Our code of ethics: “engage only in those practices that are within our scope of competence.” (If we are not competent we shouldn’t be doing it)

Q

MD vs SLP

A
  1. MD: most interested in diagnosing the underlying medical problem causing dysphagia
  2. SLP is interested primarily in identifying a dysphagia, understanding the nature of the dysphagia and planning treatment.

Q

Time of Endoscopy

A
  1. Endoscopy is not time restrained as fluoroscopy is.

2. We can stay in the nose while the patient eats their entire meal- can watch for fatigue

Q

Pros of Endoscopy (5)

A

Repeat endoscopy exams can be done more easily and with less hesitation than fluoroscopy because they:

  1. Cost less
  2. Deliver no radiation
  3. Can be brought to the patient
  4. Can be used as biofeedback
  5. Can observe patient in their natural feeding environment

*** Can perform more than 1 time in a day if you need to.

Q

Five components of FEES

A
  1. Assessment of anatomy of the pharyngeal stage as it affects swallowing (can only see this stage)
  2. Assessment of movement and sensation of critical structures within the hypopharynx and laryngopharynx
  3. Assessment of secretion management (MBS cannot do this)
  4. Direct assessment of swallowing function for food and liquid
  5. Response to therapeutic maneuvers, interventions and behavioral strategies to improve safety & efficiency of the swallow.

Q

Indications for a FEES exam (9)

A
  1. Positioning in fluoroscopy problematic
  2. Transportation to fluoroscopy problematic
  3. Concern about excess radiation exposure
  4. Severe dysphagia with very weak or possibly absent swallow response
  5. Post-intubation or post-surgery. Endoscopy can visualize larynx directly for signs of trauma or neuro damage
  6. Tracheostomy if you suspect laryngeal competence may be compromised (don’t have a passy muir speaking valve)
  7. Need to assess fatigue or swallow status over a meal
  8. Repeat exam to assess change; to assess effectiveness or need for maneuvers
  9. Biofeedback- can reassess a chin tuck with FEES

Q

Do FEES when patient demonstrates: (5)

A
  1. Hypernasal voice
  2. Hoarse, breathy voice, or aphonic
  3. Wet voice quality
  4. Rapid respiratory rate; effortful breathing (can they hold their breath well enough to swallow)
  5. Inability to handle saliva/secretions
    a. Good for these because you will get to see the larynx and VF.

Q

FEES Procedure (7)

A
  1. Clean and stimulate the mouth prior to starting exam- ice chips
  2. Explain the procedure
  3. Anesthesia?- typically stopped using anesthesia
    a. Lidocaine gel on cotton tipped applicator
    b. Lidocaine soaked cotton gauze
    c. Decongestant- can use nasal spray to lessen decongestant
  4. Prepare the food
  5. A fiberoptic laryngoscope is passed transnasally to the hypopharynx to view the larynx and surrounding structures- getting it in is the skill
  6. Patient is led through various tasks to evaluate the sensory and motor status of the pharyngeal and laryngeal mechanism
  7. Food and liquid is provided to assess the integrity of the pharyngeal swallow.
17
Q

What to look for during FEES (11)

A
  1. Ability to protect the airway- are they closing the VF
  2. The ability to sustain airway protection for a period of several seconds- can they do this for 5-7 secs.
  3. Ability to initiate a prompt swallow without spillage of material into the hypopharynx
  4. Sensitivity of the pharyngeal/laryngeal structures
  5. The effect of anatomy on the swallow
  6. Appropriate postural changes and swallowing maneuvers are attempted as soon as problems are detected so that the examiner can determine the optimal interventions to improve the safety and efficiency of the swallow.
  7. Timing and direction of movement of the bolus through the hypopharynx
  8. Ability to clear the bolus during the swallow
  9. Presence of pooling and residue of material in the hypopharynx
  10. Timing of bolus flow and airway protection
  11. Patient response to residue, penetration and aspiration
18
Q

Use of food dye- 7

A
  1. Originally, it was common practice to tint food blue or green for better visualization.
  2. Food dye was commonly used in enteral feeds to detect aspiration.
  3. 2003 – FDA warned us of serious adverse events associated with the use of blue dye.
    a. Medical world should not use it, 12 deaths
  4. Instead of excreting the dye, patients with increased gut permeability were found to absorb the blue dye
  5. This discolored body fluids and skin and caused at least 12 deaths.
  6. Patients at risk for increased intestinal permeability include those with:
    a. sepsis
    b. surgical interventions
    c. burns
    d. renal failure
    e. trauma
    f. shock
    g. inflammatory bowel disease
  7. Instead of blue or green dye, use foods with natural color.- grape juice, milk, orange juice
19
Q

Protocol (5)

A
  1. Assessment of anatomy and sensorimotor function of the:
    a. Velopharyngeal mechanism

b. base of the tongue and pharyngeal
structures(at rest and in motion)

c. laryngeal structures (at rest & in motion)
2. For all movements, note:
a. Symmetry
b. Range of movement
c. Agility/Briskness of movement
d. Precision/timing/coordination
3. Delivery of food and liquid
4. When abnormal swallowing behaviors are identified – the examiner generates hypotheses about their cause and then tests the hypotheses by asking the patient to perform tasks
a. Premature spillage, chin tuck, ask them to hold (anterior bolus hold), try teaching a supraglottic swallow to close the larynx or the mendelsohn to clear the pyriform swallow
5. Make appropriate therapeutic recommendations.

20
Q
  1. Importance of Secretions
  2. Describe secretions
  3. Murray’s Findings
A
  1. Secretions are predictive of swallowing success.
  2. Rating of secretions:

0 Normal (moist)

1 Pooling outside of laryngeal vestibule anytime during observation

2 Pooling in laryngeal vestibule transiently, spills in over the observation period or patient clears them at some point

3 Pooling in laryngeal vestibule consistently. There continuously and patient does not clear them.

  1. Describe secretions:
    a. Appearance (color, viscosity) Thick, stringy, creamy, clear and frothy (not as bad), blood tinged
    b. Patient response (sensitivity)
    c. Do they clear with spontaneous or cued swallows
    d. Frequency of spontaneous swallows

3.
a. 100% of pts. rating a 2 or a 3 aspirated food or liquid

b. 53% of pts. rating a 1 aspirated food or liquid

c. Ratings of 2 or 3 high risk for aspiration
Rating of 1 considered at risk

See secretions- usually indicates that they won’t be very successful at eating safely

21
Q

Ice Chip Protocol

A

If patient demonstrates a great deal of secretions and they cannot be cleared either spontaneously or through cued swallows, consider an ice chip protocol.

  1. If ice chips were never even partially swallowed, recommend aggressive management of secretions & oral hygiene
  2. If ice chips are beneficial(stimulated more frequent swallows, cleared or thinned the secretions), recommend delivery of ice chips in regulated amounts, several times/day.
22
Q

If the bolus spills into the pharynx, what path does it take? (4)

A
  1. Outside the larynx
  2. On the rim of the larynx
  3. Within larynx

23
Q

5 pt. Ashford Scale

A
  1. normal
  2. laryngeal penetration- cough it out
  3. Penetration without clearing
  4. Aspiration with clearing
  5. Aspiration without clearing
24
