Q

What is the UES role in swallowing?

A

• Role in swallowing:
o Pressure drives it to open, which is caused by the larynx elevating
o Cricopharyngeus muscle opens to permit entry of bolus into esophagus.
o It prevents reflux of esophageal contents into the pharynx to guard airway aspiration.
o This stage is involuntary - occurs in 1 second

Q

Define the NTS.

A

It’s a junction box - coordinates large amount of input and output for sensory/motor (makes sense of sensory info) -including respiratory, gag
• The Vagus nerve in the medulla controls motor information. The NTS controls sensory information (including taste).

  • Infants lips/mouth area are touched, mouth opens and sucking/suckling begins
  • its important because it facilitates transition from breast to bottle
31
Q

When is the right time to introduce an infant to food?

A

• around 4-6 months when reflexive responses have diminished along with motor development of body and upper extremities- so they can hold a cup

32
Q

  • Frequent swallowing
  • Emesis-vomiting
33
Q

What is failure to thrive and why is it so important?

A
  • failure to grow based on established growth standards for age and gender
  • important because children who do not get adequate nutrition MAY NEVER RECOVER from the effects because the central nervous system is still developing
  • children may also not be receiving proper nutrition due to poor dentition, medical complications, poor communication, and genetic growth failure
34
Q

What are the different methods utilized to feed infants who may not be eating by mouth?

  2. Failure to advance to age appropriate foods
  3. Excessive Vomiting
  4. Negative Mealtime Behaviors
  5. Failure to Thrive
  6. Gagging or Choking
42
Q

How do you know if the infant is having a sensory issue?

A
  • Unable to sort solids and liquids
  • Holds food under tongue and cheek
  • Demonstrates nipple confusion with breast-feeding and bottle feeding
  • hyperreactive-extreme response to taste/temp.
  • hypoactive- diminished response to taste/temp-need strong flavors
43
Q

Why is posture so important?

A
  • Oral phase → then tongue would be retracted, poor lip seal, and reduced lingual movement, and higher risk for aspiration.
  • pharyngeal phase →
  • esophageal phase → higher incidence of reflux because of gravity helping reflux so if child is hyperextended you want them to be more forward
44
Q

How do you know that a premie is ready to eat?

A
  • Cardiac, respiratory status
  • Bowel sounds adequate
  • Feedings can be done with minimal respiratory distress
  • Tolerance of bolus feedings
  • Infants need to be OFF the ventilator to even consider oral feeding.
  • suck/swallow/breathe needs to be regulated
45
Q

What is OST?

A

Oral Sensorimotor Treatment→ using sensory stimulation to improve eating and drinking. You are trying to desensitize pt from different components (lips, tongue, jaw, etc.). Not giving them anything edible, just stimulating their senses

46
Q

Why are there differences in bottles and nipples for infants? Explain your answer.

A
  • infants have different needs.
  • Dr. Brown’s → reduces air, makes sucking easier
  • syringe bottles → controls volume
  • chu chu→ for cleft palates
  • wide neck nipples → improves lip closure
47
Q

What are the goals of behavior treatment?

A
  • basically counseling! -least intrusive treatment

A

to achieve that the patient swallow safely but also maintain or maximize NUTRITION

55
Q

Many Dementia and Alzheimer patients exhibit oral agnosia. What is it? Give an example.

A
  • inability to recognize food - tactile stimuli from the face, lips, and oral mucosa are not functioning so they may not be able to tell that a non-food item is something they’re not supposed to eat
  • May try to eat the silverware because they think it is food since they’re putting it in their mouth
56
Q

Why can patients with TBI (traumatic brain injuries) difficult to treat for dysphagia?

A

Behavioral Issues: Impulsive, poor awareness (no awareness of deficits or what has happened to them), attention issues

57

59
Q

What affect does anti-psychotic medication have on the stages of swallowing? WHY?

A

o Causes Idiopathic/Iatrogenic Dysphagia - —these drugs are meant to slow down the CNS (brain) and over time it will slow down the swallow
o This is important because choking and psychomatic dysphagia can result from being on these meds for an extended period of time

60

o	edema
o	trismus
o	odynophagia (painful swallowing)
o	xerostomia
o	dental changes
o	fibrosis (scarring of tissue)
62
Q

• how does radiation affect swallowing?

A

o becomes extremely difficult due to xerostomia, odynophagia, and potential fibrosis (radiation is like getting an extreme sunburn inside your body)

63
Q

Why is dry mouth (xerostomia) a problem in head and neck cancer patients?

A

• because salivary glands are radiated

64
Q

When should swallow treatment begin for a head and neck cancer patient?

A

• need to build up muscle strength before the event so they come out where they were pre-treatment

65
Q

Why is it important to keep a head and neck cancer patient swallowing EVEN if they are aspirating? (Think what changes in the muscles occur)

A
  • if they don’t keep swallowing they will develop fibrosis
  • DO NOT LET THE MUSCLES ATROPHY AND TURN FIBROTIC, KEEP THEM SWALLOWING!
  • DO NOT MAKE THEM NPO!
  • If they don’t swallow, those muscles will turn to scar (fibrosis), the more they don’t use it, the more the muscles will turn to stone (become fibrotic).
66
Q

What is trismus?

A
  • Inability to open the mouth very much

* muscle spasms in the jaw that keep the mouth clenched shut

67
Q

What is a total laryngectomy
