short term oral nutrition required for up to 30 days
28
contraindications for NGT
facial trauma, patient intolerance and embarrassment
29
Indications for PEG
oral feeding has not commenced within a month
| and realistically can't manage enough orally to meet nutritional needs
30
Contraindications for PEG
patient tolerance
risk of surgery
cost of surgery
31
2 types of feeding regimes for non oral nutrition
Bolus ( meal time feeds)
| Continuous enteral feeding
32
Regime to progress from non-oral to oral nutrition
* Bolus feeding continue for 3-5 days to re-stretch stomach and re-initiate the hunger cycle
* Introduce one oral meal daily for one week, with more meals added as tolerance increases
* Tube feeding is modified as oral intake increases
* Need a maintenance phase before tube is removed - need to maintain oral intake over time, use food diaries to determine
33
Information to consider when recommending feeding options
amount and frequency of aspiration
diagnosis
history of pneumonia
ability to complete manoeuvres
34
Information to consider when recommending feeding options
```
amount and frequency of aspiration
diagnosis
history of pneumonia
ability to complete manoeuvres
QOL
impact of being NBM on swallowing function (consider mixed feeding)
how much can client eat/drink by mouth
informed consent of client
```
35
3 common reasons for tube feeding:
1. The patient's inability to sustain nutrition orally although the swallow response is safe
2. The requirement for sufficient calories on a short-term basis to overcome an acute medical problem
3. The risk of tracheal aspiration if the patient is allowed to eat orally
36
management of dysphagia is based on ..
client wishes, history and risk (aspiration, choking, malnutrition & dehydration)
37
goal setting considerations
* Diagnosis
* Prognosis
* Severity of dysphagia
* Cognition (can they implement strategies at home)
* Comprehension
* Respiratory function
* Caregiver support
* Motivation (big factor for outcomes)
* Medical and allied health teams’ goals
* Short and long term objectives
38

64
Valsalva / effortful swallow
- with or without food?
- rehab or compensatory?
- what does it do?
used with or without food
can be rehabilitative or compensatory
may reduce depth of penetration and reduce residue through increased tongue/palate pressure, increased duration of swallow, increased tongue base movement
65
Masako manoeuvre
- with or without food?
- rehab or compensatory?
- what does it do?
```
anchor tongue with teeth and swallow
- without food
- rehab
- increases BOT to PPW contact
increases strength of phx swallow
```
66
Mendelsohn manoeuvre
- with or without food?
- rehab or compensatory?
- what does it do?
hold up lx for 5 secs during and after swallow
- with food
- rehab
- improves swallow coordination, reduces postswallow residue and aspiration by keeping PES open for longer to decrease pooling and sustains lx elevation and seals epiglottis for longer
67
Head lift / Shaker manoeuvre
- with or without food?
- rehab or compensatory?
- what does it do?
lay down, lift head 3 x for 10secs each keeping shoulders down
- no food
- rehab
- increases opening of cricopharyngeal sphincter, laryngeal elevation and increases pharyngeal contraction
68
EMST
- with or without food?
- rehab or compensatory?
- what does it do?
expiratory muscle strength training
- without food
- rehab
- increases active expiratory pressure (cough function) and hyoid movement and subsequently PES opening
69
biofeedback examples for dysphagia
surface electro myography, ultrasound, endoscopy, watching FEES or VF
70
aim of compensatory techniques for dysphagia
''redirect/improve the flow of food and eliminate symptoms, such as aspiration, but do not necessarily change the physiology of the patient’s swallow” (Logemann, 1997)
71
compensation techniques for dysphagia include
1. Postural strategies
2. Bolus control techniques
3. Volitional airway protection strategies (some crossover with rehab)
4. Prosthetic devices
5. Modifying food/fluid consistencies (biggest area)
72
What is best body posture for dysphagia?
upright with pelvis as far back in chair as possible
solid chair with arms
feet flat on floor, hips at 90 degrees
head aligned with trunk
73
Pharyngeal posturing examples
chin-tuck, head turn, head tilt, side lying and neck extension
74
What is chin tuck used for
delays in swallow, poor tongue control, reduced posterior tongue mvt and reduced airway closure (Logemann, 1983)
75
Effect of chin tuck
widens vallecular space, narrows airway entrance, pushes BOT back to PW, puts epiglottis in protective position, increases PES pressure
= reduced aspiration
76
instructions for chin tuck
Have sip or mouthful and look down at the floor
77
what is head rotation (head turn) for and what does it do?
for unilateral weakness
= reduces post swallow residue and aspiration
by directing bolus down stronger side of pharynx through rotation of head to weaker side, closing off weaker side of phx, resulting in increased amount swallowed, less residue and less aspirated
78
instructions for head turn
Look over shoulder and swallow
79
what is head tilt for and what does it do?
unilateral weakness
reduces aspiration
by leaning whole body or head to stronger side, slowing bolus providing time to adjust and protect airway
80
bolus control techniques (compensatory)
```
3 second prep,
lingual sweep,
cyclic ingestion,
dry swallows,
bolus placement (on stronger side)
modification of bolus size and rate of intake
slurp and swallow
```
81
Volitional airway protection strategies
```
supraglottic swallow
super- supraglottic swallow
effortful swallow
mendelsohn
Phx expectoration
Vocal quality checks
```
82
Instructions for supraglottic swallow?

bear down
Swallow
gentle cough immediately after
83
What is supra glottic swallow for?
aspiration preswallow as closes VF before the swallow
delay in swallow response
post swallow phx residue
increased lx excursion
84
What is supersupraglottic swallow
Hold breath
bear down
Swallow
gentle cough immediately after
85
What is super supraglottic swallow for
aspiration preswallow as closes VF before the swallow
delay in swallow response
post swallow phx residue
increased lx excursion
86

| trache valves
87
considerations for modifying textures
- nutritional adequacy
- dryness/moisture content
- particle size
- hardness/brittleness
- adding gravy and sauces
- how good is the chef
88
environmental changes to help with modified diets
* Try different sized spoons
* Try finger food
* Cut food up into smaller pieces
* Train carer to prompt client
* Only give one mouthful at time
* Use ‘nosy’ cup (AKA dysphagia cup)
* Reduce distractions
89
Cons of modified diets
- Disliked by clients (the thicker the less liked)
- may impose other health risks e.g. dehydration
- thickening reduces aspiration for 5ml bolus but not 10ml
90
Frazier water protocol
- what is it?
- pre reqs?
allowing selected patients with dysphagia who aspirate thin fluids access to small amounts of clean water between meals to increase QOL and reduce dehydration
Need good mobility, , adequate cognition, sit up straight, and good oral hygiene
91
Frazier water protocol results
few instances of dehydration or chest infection
92
Why take outcome data?
* Show change over time as a result of rx
* To contribute to the knowledge base
* For clinical accountability

impairment of CNV - swallow issues
- mastication difficulties

Also involved in combo with velum tension and elevation (tensor veli palatini) to contain bolus and close off nasophx, and hyoid and lx elevation
101
impairment of CNVII - swallow issues
- lip and cheek motor control -> inability to retain bolus is oral cavity, food pocketing
- Ant 2/3 tongue taste -> taste impacted
- salivary glands (submandibular and sublingual) - reduced saliva production -> inappropriate bolus consistency for swallowing, difficulty forming a bolus
102
Impairment of CNIX and X
- tongue general sensation and taste post 1/3
- impairments to soft palate, phx and lx:
issues with sealing nasophx and contain bolus (Palatopharyngeus)
True and false VF adduction issues -> poor airway protection
poor communication with brainstem and cortex
poor phx constriction
