Common Nutrition Risk Indicators
Failure to grow over 2-3 months
Weight/height below 5th %ile
Chronic diarrhea/constipation
Long term use of drugs
Excessive drooling
Common Nutrition Risk Indicators
Frequent reflux/emesis
Oral sensorimotor feeding difficulties
Metabolic disorders
Abnormal CBC/urine screens
Suspected caregiver neglect
Undernutrition and Growth
Acute: decreased weight-for-height (wasting)
Chronic: decreased height-for-age (stunting)
Effect on linear growth may lag weight effects by 4 months
Children who survive malnutrition - generally stunted

Undernutrition: Severity of Effects
Correlated with onset & duration
Most profound damage when period of deprivation occurs during first 2 years
Pulmonary Disease with Neurologic Impairment
Respiratory complications of dysphagiaDisordered timing/incoordinationAspiration
Airway obstruction
High risk infants (apnea & hypoxia)
Older children: disorders of respiration
Signs & symptoms of aspiration vary
Aspiration Generalizations
Usually silent with neurologic deficits
High index of suspicion for signs of pharyngeal dysmotility
Congestion during feeds
Multiple swallows per bolusDelayed initiation of pharyngeal swallow
Respiratory distress (e.g., cough, wheeze)
Congenital Laryngomalacia
Redundant supraglottic mucosaCommon mechanisms
Cuneiforms drawn inward during inspirationExaggerated omega shaped epiglottis curls on itselfArytenoids collapse inward
Stridor in Severe CLM
Inspiratory
High pitched
Loudest when upset
More evident in supine
CLM: SLP Role for Feeding
Determine most efficient oral feeding: position, liquid flow, pacing
Monitor inspiratory stridor & effect on PO
Effects of GER & nipple feeding?
Reassurance to parents regarding positive prognosis in coming months
Spoon feeding & cup drinking may be focus earlier than in typical infants

Pierre-Robin Sequence
Mandibular Hypoplasia (Micrognathia)
Glossoptosis (retroplaced tongue)
Airway obstruction
U-shaped cleft palate (not primary characteristic, seen in about 80%)
Pathophysiology: Chronic Aspiration
May be more insidious than acute aspiration (direct & indirect)
Most prone: Swallowing dysfunction & neuromuscular disease
Clinical indicators may be scarce
Laryngeal penetration (deep)
Endangerment to airway from aspiration
Life threatening physiologic alterations
Timing of Aspiration with Swallow
Before: Delay in onset of pharyngeal swallow or abnormal tongue movements
During: Ineffective laryngeal closure or timing incoordination
After: Results in residue from multiple factors (e.g., decreased tongue base retraction, reduced sensation, incoordination of pharyngeal constrictors)
Protection from Aspiration
Normal swallow
Cough
Not reliable predictor even in infants with normal swallows
By 1 mo., 90% of infants have cough reflex
Other protectors of lung (e.g., mucociliary clearance, phagocytosis by alveolar macrophages, lymphatic drainage, gag)
Swallowing Problems & GI Disease
Esophageal structural abnormalities (TEF)
Motility disorders
Inflammatory diseases
Constipation aggravates in neuro disorders
74% of CP
Multiple causes (e.g., PO with fluid)
GER Prevalence & Epidemiology
Highest < 2 years of age
Preterm infants: 63%CP: 92% with GI symptoms & signs
Healthy infants pH probe: esophageal acidification common
21% of all ped pts to GI clinic present with signs/symptoms suggestive of GER

GER Prevalence & Epidemiology
Typical symptoms of GER in < 50% in children with upper airway manifestations
25-30% of all children with GER have EER & upper aerodigestive tract symptoms/signs
Reflexes Involved in Development of Upper & Lower Airway Disease
Esophago-laryngeal reflex
Acid is introduced into distal esophagus
Laryngospasm results
Laryngeal chemoreflex
Direct acid stimulation to larynx
Apnea, bradycardia, & hypotension result
More active in infants & gradually disappear
GER Medications for Apnea in Premature Infants
Theophylline or caffeine: neither drug consistently eliminates apnea in all patients
Note: caffeine exacerbates GER in adults & older children!
Antireflux medications do NOT reduce frequency of apnea in premature infants
(Kimball et al., 2001)
Manifestations of GER are due to
effects of gastric acid, BUT
abnormalities of motility &
sphincter function cause GER
Multiple Causes of GER
Impaired LES function
Increased intraabdominal pressure
Delayed gastric emptying
Impaired esophageal acid clearance
Functional GER - “Happy Spitter”
Infants, onset usually < 2-3 months
Effortless regurgitation (spitting up)
Frequency decreases after 6 months
If infant grows well, no major work-up needed

Risk Factors (Atypical Manifestations)
Lower airway diseases
Upper airway
Upper digestive
chronic halitosis otalgia/chronic OM
loss of taste Sandifer’s syndromefood refusal chronic pharyngitis
dental caries drooling
Eosinophilic Esophagitis (EE)Entity emerged since 1997 – previously confused with reflux esophagitis
Inflammation due to allergic factors may also include upper airway disease
Not correlate with ? GER
Endoscopy
Denser infiltrates of eosinophils relate to nonacid-related cause of esophagitis
Furrows or rings often notedSteiner et al (2004)
Treatment of EE in PediatricsLack randomized controlled trialsCase series suggest
Elemental dietOral steroids Topical steroids
Lack of control group: impossible to evaluate effect of interventions

Clinical Assessment of Feeding & Swallowing: Infants & Children
Joan C. Arvedson, PhD, CCC-SLP, BC-NCD, BRS-S
[email protected] & [email protected]
Presentations of Feeding Disorders
4 Key Questions to Ask ParentsHow long does it take to feed your child?
Longer than 30 minutes, tip-off for problem
Are meal times stressful to child &/or parent?Neurologic based skill & safety issues?
Behavior and/or sensory issues?
Is your child gaining weight OK?If no weight gain for 2-3 months, sign of problem
Are there signs of respiratory problems?e.g., congestion ? during feeding; gurgly voice
Global Feeding Evaluation Goal
To determine safest & most efficient consistencies for a child to eat orally (to whatever extent possible) while maintaining adequate nutrition & hydration
Development in Typical ChildLiquid by nipple first 4-6 months
Breast milk
Formula
Strained smooth food by spoon (6 months)
Sitting with minimal support
Lumpy foods by 10-11 months
Difficult if delayed until 14-16 months
Cup drinking before 12 months
Age of Introduction to Solids
Age (months) Type of Solid
4-6 Smooth puree (SP)
6-9 SP; Textured puree; Easily dissolvable solids
9-12 Soft, mashed, & diced solids
12-18 Toddler diet of chopped table food

Airway Stability for PO Feeding
Airway stability is prerequisite for successful PO
If airway concerns are noted during physical exam, possible next steps:
Otolaryngology airway exam (FFL, DLB)
Bedside/clinical oral feeding evaluation
Combined FFL & FEES with ORL & SLP
Videofluoroscopic swallow study (VFSS)
Monitor status for a few days
Evaluation of Transition Feeder & Older Child
General observations
Posture, alertness, direction following
Oral sensorimotor function
Bolus formation & oral phase of swallow
Pharyngeal phase inferences
Therapeutic trials
Postural Control Evaluation
Muscle tone (hypotonia or hypertonia)
Central alignment relates directly to oral sensorimotor system
Presence of primitive reflexes
Level of physical activity
Self oral stimulation
Use of eye contact, head turning, & touch
Optimal Sitting Posture
Neutral head position
Neck elongation (No chin tuck for infants)
Symmetrical shoulder girdle stability & depression
Pelvis stability, hips symmetrical in neutral
Hips, knees, & ankles at 90 degrees
Feet in neutral with slight dorsiflexion (never plantar flexed), supported by firm surface
Cranial Nerve Evaluationfor Feeding/Swallowing
Lack of chewing: CN V
Facial asymmetry & lack of lip movement: CN VII
Delayed swallow & pharyngonasal penetration/backflow/reflux: CN IX & X
Tongue thrust or atrophy: CN XII
Gag ReflexIndependent of swallow
Sensory: CN IX
Motor output: CN X, XII, & V
Elicited by touching posterior pharyngeal mucosa (standard testing)
Difficult to assess importance of changes in absence of other findings

Tonic Bite ReflexJaw moves up into clenched position on presentation of spoon or other object
Response to contact to biting surfaces of side gums (molar tables)
Persistence with neurologic deficit –should disappear by 9-12 months
Cranial Nerve V
Oral Sensory vs Motor Disorders
Nipple confusion
Not differentiate tastes in bottle even with intact suck
Manages liquids better than solid foods
Sorts food in mixed texture
Inefficient suck breast & bottle
Differentiates tastes in bottle
Oral-motor inefficiency or incoordination for all textures
Swallows food whole when given mixed textures
Oral Sensory vs Motor Disorders
Holds food under tongue or in cheek and avoids swallowing
Vomiting only certain textures
Gags when food approaches or touches lip
Hypersensitive gag with solids, normal liquid swallow
Unable to hold & manipulate bolus on tongue, food falls out
Vomiting not texture specific
Gags after food moves through oral cavity
Gags after swallow is triggered with liquid & solid
Oral Sensory vs Motor Disorders
Tolerates own fingers in mouth, but not accept others
Does not mouth toys
Refuses tooth brushing
from Palmer & Heyman, 1993
Tolerates others’ fingers in mouth
Accepts teething toys, but not to bite or maintain in mouth
Accepts tooth brushing
Immature vs Abnormal Patterns
Patterns are likely to be distinguishable insuck-swallow-breathe sequencingjaw control or stability
tongue mobilitylip closure
dissociation of tongue, jaw, & cheek movements while drinking & chewing
Next Steps?Nutrition AnalysisMedical Workup (Genetics, GI, ENT, etc)Behavioral PsychologyOccupational Therapy/Physical TherapyInstrumental Swallowing Study

Important Considerations in High Risk Pediatric Patients
Radiologist must be presentFluoroscopy time minimumWell formulated Q & ACaregivers includedFindings shown to caregiversFindings interpreted & used as part of total team approach: maximize safety
VFSS Procedural Considerations
Purpose & questions formulated clearly
Positioning/seating: typical & optimal
Cooperative patient imperative for interpretation
Shortest fluoroscopy time possible
Review in slow motion, frame-by-frame
Feeding Supplies & Recipes
Readily available when caregivers are asked to bring food samplesTextures & barium recipes need to be standardizedData lacking, especially in childrenPoor relationship between viscosity of dysphagia diet foods & swallow barium test feeds of different viscosities (Strowd et al., 2008)
Preparation of PO FeedersHungry, but not starving
Schedule close to feeding time if possible
Normalize the situation as much as possibleChild’s own utensils
Video/music as needed
GT + PO: same guidelines as for total PO, unless child gets slow, continuous tube feeds
Preparation of Tube Feeder: NPO
Child should demonstrate some level of oral intake, at least for therapeutic “taste trials”
NG tube – remove in some instances
Amount per bolus: 2 to 3 ccTotal of 10-15 cc preferred for validity & reliability
Medication schedules maintained, or in some cases, adjustments needed
Child’s “State”
Typical feeding status appropriate
Increased risks for aspiration
LethargyAgitation (fussing & crying)
Cooperative child: interpretation possible in reliable & valid ways
Always remember: Just a brief window in time, not a typical meal

Procedural Decisions
No fixed order for presentations in pediatrics
Preferable to start with thinnest liquidControlled bolus size to start, e.g., spoon before going to bottle or cup drinking
Work toward thicker as needed
Not want residue in pharynx that may complicate interpretation with thinner later
Exceptions: Parents tell us that child will not accept any thing else if he gets liquid first
Lateral ViewEncompassing
Lips anterior
Soft palate superior
Posterior pharyngeal wall posterior
Fifth to seventh cervical vertebrae inferior, varying with age of child
Simultaneous view of oral, pharyngeal & upper esophagus before food is presented
Antero-Posterior View
When asymmetry is known or suspected
Unilateral vocal fold paralysis or paresis
Tonsil related questions
Other possibilities?
Keep in mind radiation exposure time
Importance of findings for management
Oral Phase Swallow Problems
Lips (poor closing, drooling, leakage)
Hesitation/pooling
Tongue action deficits
Gagging
Poor posterior tongue thrust
Passive leakage over tongue base
Delayed oral transit
Initiation of Pharyngeal Swallow

Post-swallow residue, e.g.,
Valleculae
Pyriform sinuses
Posterior pharyngeal wall
Clearance of residue?
Esophageal Swallow Findings
Upper esophageal sphincter
Opening, e.g., reduced, incoordinated (usually pharyngeal phase problem)Prominence
Bolus passage
Slow, interrupted
Retrograde movement of contrast (better term than reflux in this instance)

Vocal fold paralysis/paresis
Reduced laryngeal excursion
Pharyngeal incoordination
Pharyngonasal (nasopharyngeal) penetration, backflow, or reflux
Aspiration During Swallow
Neural control
Initiation under voluntary control
Involuntary control for completion
Airway
Closes upon initiation of pharyngeal swallow
Multiple levels of airway protection common
Aspiration After Swallow
Reduced tongue base retraction

Aspiration After Swallow
Neural Control
Involuntary for esophageal phase
Airway
Open
Precipitating factors with open airway
Pharyngeal residue spills over
Gravity brings material in nasopharynx lower into airway
Esophageal Dysphagia Diagnosis
Dysphagia for solids > liquids, structural cause likely
Dysphagia for solids & liquids similar, dysmotility likely cause
Interpretation of VFSS Findings
SLP reviews with caregivers & therapists or others involved in care
Findings by phase of swallowTiming of penetration/aspiration related to physiologic processes
If review reveals a finding not anticipated or noted during exam, SLP contacts PA or radiologist to discuss or review togetherImportant that reports are not discrepant
Recommendations After VFSSChanges in route of nutrition/hydration
Nutrition guidelines
Position & posture changes
Alterations of food textures, temperatures
Utensil changes
Changes in feeding schedule & pacing
Oral sensorimotor program with food
Nonnutritive oral sensorimotor program
Management: Prognosis & Priority
Oral feeding prognosis tied closely to
Underlying etiology & diagnosis
Neurologic findings
Cardiopulmonary status
Feeding priorities established on basis of
Severity
Combination of deficits
Principles for Repeat VFSS
Same as for initial VFSS

Infants in Need of Intervention
Prolonged stay in NICU Extensive exposure to negative oral stimulation, e.g., endotracheal tubes, suction, sticky tapeBefore oral feeding introduction, time is needed
Break oral & perioral aversion Offer exposure to sucking via nonnutritive oral sensorimotor therapy (e.g., pacifier)
Nonnutritive Stimulation
Enhances oral sensorimotor skill development
Builds on in utero experiences of sucking & swallowing
Helps when size & shape of pacifier match infant’s mouth
NNS Cochrane Review
21 studies (15 randomized controlled trials, all infants born < 37 weeks gestation)Main Outcome
NNS significantly decreased length of stay (LOS) in preterm infants No consistent NNS benefit revealed with respect to other major clinical variables
Positive clinical outcomes: Transition from tube to nipple & better bottle feeding performance
Pinelli & Symington, 2005
Oral Stimulation for Preterm Infants
Exp. Group: oral stimulation of oral structures 15 min. once per day for 10 daysControl group: sham oral stimulationStarted 48 hr after d/c of nasal CPAPExp. Group reached independent oral feeding faster (X=11 days, control = 18 days). No difference in length of stay.
Fucile, Gisel, & Lau, 2002
Nipple Feeding Principles
Non-stressful for infant & feederMost efficient suck:swallow ratio is 1:1Burst of rhythmic suck/swallows followed by cessation of sucking and a breathTotal feeding completed in about 20 min.No increased work of breathing, fatigue, or signs of respiratory stress
Interventions
PositioningLimit feeding duration (poor endurance)
Nonnutritive oral sensorimotor therapy
Jaw/cheek support
External pacing

Tools for Oral FeedingBottles & nipples
IndividualizeGive infant time to adapt/learn
Thickeners – Be cautious!!!May assist bolus formation, slow flowMay slow gastric emptyingMay increase coughingMay interfere with digestion
Evidence-Based Guideline: Introduce Oral Feeding (McCain 2003)
Requirements for oral feeding (PO)Sustain awake behaviorCoordinate sucking-swallowing-breathingMaintain cardiorespiratory stability for time to ingest a caloric volume adequate for growth
Neurologically immature preterm infant <32 wk post conceptual age (PCA) cannot meet the above requirements
Behavioral Organization
< 32 weeks: typically not express hard crying or deep sleep with regular respirations
By 32 weeks, infant expresses full range of behavioral states – important milestone for PO as need to sustain organized, awake behavior
From 32 wks PCA to term age, maturation of brain structure is associated with improvement in behavioral sate expression & motor organization
Self-Regulation ReadinessAt 32 to 35 weeks PCA
Feeding based on awake or restless behavior
PO progressing & concluding based on infant’s ability to tolerate without fatigue or distress
Successful feedings: Increase in quiet sleep time & shorter feeding times
Adequate weight gain compared to infants fed prescribed volumes
More opportunities to practice nipple feeding
Demand FeedingBy 35 wks PCAFunctional suck-swallow-breathe pattern allowing for safe PO is not present until 32-34 wks PCA (Volpe, 2000)Infants 32-36 wks PCA
Suck-to-swallow ratio 3:1 & 4:1 with occasional disruption in regular breathingOccasionally exhibit tongue twitching or tremors
Principles of Management
Whole child approachTotal oral feeding cannot be the goal for all chidlren
Nutrition & respiratory status critical
GER managed optimallyChanges in management needed
with gains or regression

Food RulesScheduling
Meal times < 30 min + planned snacksNothing between meals, except water
EnvironmentNeutral atmosphere - no forced feedingNo game playing; no reward with food
ProceduresSolids first; self-feeding encouragedMeal over if food is thrown in angerClean up only at end of meal
Intervention Based on Developmental Skill Levels
Oral stimulation for infantsSpoon feeding & chewing readiness
Cup drinking
Texture changes
Spoon Feeding LearningUse foods that stick to spoonAvoid foods
Too much liquid (e.g., soups)
Slippery (e.g., sliced peaches)
Roll off spoon (e.g., peas)Use spoon with flat bowl
Plastic coated non-breakable
Cup Drinking
About 1-2 months after spoon feeding is well establishedOpen cup with thickened liquid (milkshake or fruit “slush”)Cup: wider at top, clear so feeder can control amount per sip wellChild can “help” with handsIndependent: Lip helps reduce spills
Chewing Practice
1-2 months after spoon startedGradual changes from smooth puree
One change at a time (e.g., taste, texture)
Thin strip placed on molar table/surface
Alternate sides to promote later tongue action
Finger Foods
Readiness
Pick up objects with thumb & fingers
Bring fingers or objects to mouth
Bite, chew, & swallow variety of textures
Guidelines
Food in small strips
Place food in front of child (2-3 pieces)
Guide hand to mouth as needed
Fade help as appropriate

Common Problem TexturesThin liquidsDry or lumpy foods
Pureed food between bites of dry foodMulti-textures foods (e.g., vegetable soup)
Foods that do not dissolve with saliva
Raw fruits & vegetables
Modifying TexturesModifier should match flavor of food
Fine cracker crumbs in soup
Apple juice with applesauce
Milk with yogurt or puddingWhen offering a new texture
Few spoons of familiar texture first
Then new texture (e.g., blended carrots, fork mashed)
Oral Sensorimotor Treatment for Anatomic Problems - Jaw
Thrust: tone
Retraction: tone
Clenching: tone
Instability: tone
Tonic bite reflex: not related to tone
Mouth play: fingers, toys Assisted toothbrushingProne position; Forward pull under jawMouth play for gradual openingActivities for jaw closurePressure at TMJ; sensory stimulation; coated spoon
Oral Sensorimotor Treatment for Anatomic Problems - Lips
– Retraction: tone
Limited upper lip movement: & tone
Cheeks: tone
Reduced sensory awareness
Finger tapping, vibration
Varied textures, temps Tapping & stroking
Stroke & tap, esp. TMJ
Varied textures, temps; drop of liquid in corner of lips
Oral Sensorimotor Treatment for Anatomic Problems - Tongue
Thrust: or tone, or respiratory stress
Jaw stabilization, thickened liquid at lip, food placed on sides, exercises for lateral tongue movement, spoon at midtongue with downward pressure
Oral Sensorimotor Treatment for Anatomic Problems - Tongue
Retraction: or tone
Hypotonia: tone
Prone position, tongue stroking back to front, chin tuck for older child, upward tapping under chin
Vary textures & tastes to sensory input; Food or liquid added gradually

Oral Sensorimotor Treatment for Anatomic Problems - TongueDeviation
Limited movement
Head at midline; stimulation of less active side with finger, toys, toothbrushVary textures, temps, tastes; Vibration
Oral Sensorimotor Treatment for Anatomic Problems – Soft PalateNasopharyngeal reflux
Upright or prone position; Angled bottle for prone position; Cheek & tongue function activities; Thickened liquids (if swallow is normal)
Feeding with Gastrostomy TubeUpright positionPump or gravity delivery, air removed
Formula at room temperature
Feeding time minimum or > 20 min
Oral stimulation during feeding (or prior)
Tubing flushed after feedings or meds
Mealtime Behavior ProblemsRefusal of new foods
Introduce one at a timeAvoid power struggles
Refusal of groups of foods
Respect preferencesDo not beg, punish, or bribeSet a good examplePrepare foods in a variety of waysSelect other foods with same nutrients
Mealtime Behavior ProblemsWanting a particular food every day
Probably change with boredom over timeDo not call attention to behaviorParent controls what food is served
Consider food “jag” at snackInclude other foods typically liked
Acting outIgnore undesirable behaviorAttend to & respond to desirable behaviorModel good eating behaviors
Treatment Summary
Airway & nutrition highest prioritiesOral sensorimotor practice can NOT jeopardize nutrition & pulmonary statusForced feeding or prolonged feeding times: never appropriateGI tract (e.g., GER)
major inhibitor of appetiteaspiration risk
Whole infant/child approach is critical
