Class 8 Flashcards
According to the Power Point discussion, a decrease in oxygen saturation levels below _____ indicates a risk for swallowing impairment.
90%
An examination technique whereby the examiner tests laryngeal elevation by feeling the thryoid notch during the swallowing process is called______.
Digital Manipulation/laryngeal palpitation
The _________test is specific to patients with tracheostomy tubes and involves evaluation of suctioned tinted boluses to assess aspiration.
Modified Evans Blue Dye Test
What is the purpose of using a thickening agent like “Thick-It” or “Simply Thick” in liquids?
To alter the consistency of liquids for increased swallow safety.
According to the Functional Oral Intake Scale, a client who has been evaluated and is recommended for an oral diet but with pureed consistency only (puree solids and pudding thick liquids) would be a level______.
4
The ______is an example of a questionnaire for dysphagia performed to determine the need for further evaluation.
The Baker, Fraser & Baker Test
The pharyngeal stage of the swallow makes two distinct “click” sounds. It is possible to assess pharyngeal stage dysphagia using a technique called __________________.
Cervical Auscultation
According to Logemann in the classic article by Langmore and Logemann (1991), approximately _____of the cases of silent aspiration go undetected during a clinical/bedside evaluation.
38-40%
In the article by Tohara, Seitoh, Mays, et al. (2003) the combination of which three tests listed below provided the best predictors of aspiration when an MBS or FEES was not available (e.g. nursing home setting)?
3 oz., water test, 4 grams of pudding swallow, and a still X-ray of the lungs.
In the article by Suiter & Leder (2008) the research question is asked, “Does the 3 oz. water swallow test identify individuals who aspirate thin liquids?” What were their conclusions?
Yes, it had good sensitivity for identifying aspiration of thin liquids.
Clinical/Bedside Evaluation
More of a screening to get an idea of what we are working with
According to Logemann in the classic article by Langmore and Logemann (1991), approximately 38-40% of the cases of silent aspiration go undetected during a clinical/bedside evaluation (due to silent aspiration)
(Just the) Instrumental Evaluation
NEED TO DO BOTH. Logemann says to ALWAYS do one.
Some long-term care facilities do not have an MBS or FEES machine available.
Use as a screening for instrumental tests
Use as an outcome measurement
McCullough, Wertz, & Rosenbek (2000) only 50% reliable on clinical exams. Need to standardize the clinical exam.
Langmore & Logemann Article
Discussion:
Pros and Cons of a bedside evaluation
Pros: Questionnaire, patient concerns, problems, functional issues
Cons: However, it takes more time and it is not that reliable for detecting what is really going on
Why does Logemann feel that you should always include a clinical exam?
Clinical questions to be answered
Percentage of silent aspiration missed
Langmore recommends FEES, why?
Logemann’s 5 Reasons to Pursue a Clinical Exam
1) To define a potential cause of a swallowing disorder
2) To establish a working hypothesis
3) To establish a tentative treatment plan
4) To develop a potential list of questions that may require further study
5) To establish the readiness of the patient to cooperate with further testing
Clinical Evaluation:
3 Main Components of a Clinical Evaluation
1.) Medical History-
Chart Review
Questionnaire
2.) Physical inspection of swallow mechanism
Cranial Nerve Exam
Oral-Mech. Exam
3.) Observation of swallow with test swallows
3-oz. water test- The Source, Tohara, et al., DiPippo, Holas, & Reding (1992); Garon, Eagle, & Ormistrin (1995)
Prediction of Aspiration with screening tests
Various consistencies attempted
Dysphagia Questionnaire
Ask client to describe their problems and symptoms
Helps you find out what to evaluate more closely/discover patient concerns
May not be able to describe problems
Unreliable or responses may not fit objective findings
Groher & Crary (textbook) found this is easier when problems are severe vs. milder dysphagic symptoms
Samples of Questionnaire
Baker, Fraser & Baker (1991) (in text Box 9-1)
Burke Dysphagia Screening Test (DiPippo, 1994)
Wallace Dysphagia Screening Test (Wallace, et al., 2000)–Designed specifically for Parkinson’s Disease
General Categories of Interview/Questionnaire Findings
Obstruction Liquids vs. Solids Gastroesophogeal Reflux Eating Habits Medical History
Physical Examination
Box 9-2, Page 173
Feeding Tubes
Tracheostomy Tubes
Respiration- Oxygen Saturation, Rate
Oxygen levels below 90% indicates at risk for swallowing impairments: Practice O2 sensor
Mental Status
May be unable to cooperate.
Cranial Nerve Examination: Which ones?
Sonies assessment or screen
Facial Muscles
Lips at rest and at work—upper vs. lower motor neuron damage
Muscles of Mastication
Tongue Muscles
Look for fasciculations, atrophy, deviation
Oral Cavity
Lesions, thrush infection, saliva, dentition
Oropharynx
Velum at rest and at work, gag reflex (NOTE: presence or absence not indication that they have normal swallow or are at risk. Absence might suggest other problems if other findings are noted
Pharynx
No clinical tests of pharyngeal function: listen for vocal fold function.
Pharyngeal Function- Clinical Evaluation
Vocal Fold function test Digital Manipulation/ Laryngeal palpation test Cervical Auscultation Three audible sounds Stethoscopes: -Littman Cardiology II (3M Corp.) -Rappaport-Sprague Pediatric Size (H-P) -Bell surface vs. Flat Surface
Testing Aspiration Clinically-
Is it Reliable? Is it Safe?
Mann & Hankey (2001) Stroke patients N=71) Regression Analysis of 23 Clinical features 6 variables predictive of aspiration: Impaired pharyngeal response Male Disabling stroke Incomplete oral clearance Palatal weakness >70 years old Leder & Espinoza (2002) Stroke patients (N=49) Clinical exam = underestimated those who aspirate and overestimated those who did not aspirate
Swallow Tests
Tohara, et al. Article Review
Three measures recommended for an effective alternative to instrumental examination
3 oz. purified water
4 grams of pudding (safest, next safest is nectar)
Plain X-ray of the pharynx
Groher & Crary:
Crushed ice first
5- 10 ml of water then 20-ml bolus of water
Cup versus straw
Cup is safer
Clinician presentation versus client presentation
Clinician can control amount
Solids in sequence of difficulty
Puree and pudding is safest, next safest is honey and nectar consistency
Modified Evans Blue Dye Test- MEBD
For individuals with tracheostomies
Test bolus’ with blue dye
Deep suctioning every 15 minutes for one hour
Poor reliability
MEBD: Thompson-Heney & Braddock, 5 patients, MEBD found no aspiration but MBS/FEES found that all 5 aspirated.
Feeding Evaluation
Consistencies: Simplest to most difficult
Purees
Thickened liquids:
Pudding thick (easiest to swallow)
Honey thick
Nectar thick
Chopped/ground/diced
Mixed consistencies (soup thin and chunks, or fruits (solid and juice)
Regular solids: mechanical soft (potatoes, bananas, beans) to crumbly (crackers, biscuits, nuts, corn bread, popcorn, chips)
Thin liquids
Tools
Spoon (simplest, safest)
Cup
Straw
A Clinical Exam Tray (The Source, pg. 37-38)
¼ cup thickening agent: Thick-it, Simply Thick (looks better, tastes better, but more expensive), etc.
¼ cup puree fruit or pudding
¼ cup ground meat
¼ cup regular meat
¼ cup diced mixed vegetables or chopped peaches
¼ cup rice or noodles (soft solid)
1 slice white bread (mechanical soft)

1 sugar cookie (mechanical soft or crumbly)
1 /2 cup Cheerios (with milk, mixed consistency)
½ cup milk (thin)
½ cup apple juice, tea, or water (thin)
Cup, straw, spoon, knife, fork
Work with dietician at facility to arrange for a standard tray to be developed for this test.
