Welcome! • Assessment and Treatment of Pediatric Dysphagia • SPHSC 543 B • Website: http://faculty.washington.edu/jul2/ • Syllabus
Prevalence • Feeding disorders • 25% in all children • 80% in children with special healthcare needs and developmental delays • (Manikam & Perman, 2000) • Swallowing disorders • Unknown in pediatric population
Adult vs infant • Small mandible • Tongue • Sucking pads till 4-6 months • Directionality of movement • Preferential nose breathers • Close proximity of tongue, soft palate and pharynx • Position of larynx • Preserved until 3-4 mos when anatomical changes start to take place
Anatomical changes • Mandibular growth • Sucking pads absorbed • Oral cavity elongates • Lip valving • Neurological maturation • TMJ grading • New directionality • Teeth • Laryngeal descent
Embryonic period: Weeks 1-8 • 3rd week • By 4th week • By 7th week
Fetal period: Week 9-Birth • Weeks 12-14 • Weeks 15-18 • Week 24 • Weeks 26-29 • Weeks 30-34 • Weeks 35-38
Embryologic Abnormalities • CNS damage • Congenital malformations – both genetic (chromosomal abnormalities) and environmental factors with some a combination of both acting together • Upper airway anomalies/anatomic defects
Problems • Cerebral palsy • Moebus • Treacher Collins, Pierre Robin, palatal clefting • Beckwith-Wiedemann syndrome, Down syndrome, ankyloglossia • Tracheo-esophageal fistula, diaphragmatic hernia, hypertrophic pyloric stenosis • Tetrology of Fallot, transposition of the great arteries, atrialseptal defect, ventricular septal defect
Reflexes related to swallowing • Programmed responses to specific sensory input • Developed early in utero • Allow infant to seek out and obtain nutrition safely • Interplay generally more important than presence/absence • 2 categories of oral reflexes: • Assist in the acquisition of food • Protect the airway
Adaptive • Rooting • Sucking • Suck-swallow response
protective • Gag • Cough • Tongue protrusion
Other reflexes • Phasic bite • Transverse tongue response
Suckling and sucking • Nutrition • Calming • Exploration • Physiologic flexion
Sucking • Positive pressure/compression • Negative pressure/suction • Pressures may be used differently between breast and bottle.
Mechanics of Sucking • Tongue • Jaw • Lips • Cheeks • Palate
Sucking pressure • Variable • Dependent on state • Fluid flow • Nipple characteristics
problems • Anatomic defects • System dysfunction • Tone/muscular control • Oral pain
Breastfeeding • “Ideal” food • Suck/swallow sequence similar to other nipple feedings
Breastfeeding • Nipple elongates • Jaw and tongue elevation • Areola compressed • Milk expressed • Jaw lowered • Lactiferous ducts refill
breastfeeding • Letdown reflex • Suck/swallow sequence • Bursts and pauses • Jaw and lips • Volume
