Outline
• Case History with Relevance to Neonatal Dysphagia
• Approach to Diagnosis • Therapies and Outcomes
• Scientific Reasoning Symptoms, Signs and Procedures
 Full term born infant, lethal congenital heart disease underwent Domino Heart Transplant. Recovery was gradual and complete
 Severe multiple life threatening events requiring intubations, failed extubation, Prolong ICU stay and monitoring, Normal Cardio‐Respiratory functions otherwise
 Severe Feeding difficulties, GE‐reflux, Emesis, Dysphagia, Aspiration, Choking spells with Oral feeding attempts, Aspiration at Upper GI and Video‐fluoroscopy swallow study  Arching and Irritability, Symptoms with Intragastric Feeding, Refusing Oral Feeds, No response to H2 antagonists for acid suppression. Infant on metoclopramide already.
 Medical, ICU, Cardiac and Speech Therapy teams: Consideration for Gastro‐Jejunal feeds, Tracheostomy and Fundoplication
 Feeding Failure and Parents reluctant for these procedures 
Summarizing Reasoning for Feeding Failure
 Prolonged ICU Care, Mechanistic Continuous Intragastric or 



Transpyloric feeds, No motivation to Feeding, Lack of Normal Bio‐rhythms
Major Intra‐thoracic Cardiac Surgery, Inflammation, Organ Distortion, Edema and Scarring Painful procedures, Aversion to oral stimuli
Anorexia and lack of thirst, IV fluids, Concurrent medical conditions and Drug side‐effects
 Growth Failure, 3.8 kg at 13 weeks
How can fix all these problems?

Feeding Management Strategies








Treatment of GER, Acid suppressive therapy with PPI
Avoidance of Metoclopramide Continuous gavage feeds – Simulated bolus feeds – Bolus feeds Postural adaptation and rotation, Minimizing Sensory Stimuli, Sensory modification
Consistent occupational therapy, Pacing, Posture, oromotor stimulation, Pacifier, Kangaroo Care, Non‐nutritive sucking with feeds
Permissive volume restriction possibly stimulating thirst, Hunger manipulation, Positive reinforcement
Introduce Oral feeds, Aim for Quality of feeding session, Regulated flow of feeds, Slow feeds, Feeding session for ~30 min
Close monitoring for bradycardias or desaturation
 Outcomes:  Full PO feeding achieved
 Averted G‐tube, Tracheostomy, and Fundoplication Scientific Reasoning: Gut motility sequences Modified during Oral Feeding Study 1, 51 wks PMA, 3.8 Kg Study 2, 60 wks PMA, 4.7 Kg
