Pain, feeding and respiratory care in severe neurodisability: Viva

Branch 1: Reading the behavioural change as pain

A strong candidate states at once that a change from baseline in a non-verbal child with severe neurodisability is pain or a treatable medical source until proven otherwise. The arching, grimacing, and sleep disturbance are not his baseline dystonia; they are a signal that something hurts. The candidate names the observational pain tools, the revised FLACC, the Non-communicating Children's Pain Checklist, and the Paediatric Pain Profile, and explains that the child cannot self-report so a validated tool replaces the guess. The next step is to give prompt analgesia to settle the distress enough to examine, and then to search the head-to-toe and system list for the source. [1]

When the examiner pushes for the sources, the candidate lists the treatable ones by system: the musculoskeletal sources of hip subluxation and dislocation, occult fracture, scoliosis, and contractures; the gastrointestinal sources of reflux, oesophagitis, constipation with impaction, and dental abscess; the genitourinary sources of urinary tract infection and stones; and the neurological sources of dystonia and neuropathic pain. The candidate stresses that the discipline is to keep searching until a source is found, because assuming there is none is the most common and most harmful error in this population. [1]

Branch 2: The feeding pathway

When asked about the feeding problem, the candidate explains that the prolonged oral feeding with coughing and choking and the falling weight point to an unsafe swallow with aspiration and failure to thrive. The key investigation is the instrumental swallow assessment, ideally a videofluoroscopic swallow study, which directly visualises aspiration across textures and guides the decision between modification and tube feeding, alongside a dietetic assessment and growth on cerebral palsy-specific charts. [8]

The candidate then justifies the gastrostomy on the grounds of unsafe swallow and failure to thrive, citing the prospective evidence that gastrostomy improves weight and nutrition and eases the feeding burden for the family, and names the critical caveat that a gastrostomy does not eliminate aspiration because the aspiration of saliva and reflux persists, so reflux must be assessed and treated alongside the tube. The candidate frames the gastrostomy as a step that improves nutrition and reduces food aspiration, shared in decision with the family and the feeding team, not as a failure of oral feeding. [8][9]

Branch 3: The respiratory pathway

When asked about the breathing, the candidate names respiratory illness as the leading cause of death and admission in severe cerebral palsy, and identifies the modifiable risk factors: weak cough and poor clearance, sialorrhoea, aspiration of saliva and reflux, scoliosis, and sleep-disordered breathing. The candidate states the critical physiological principle that in neuromuscular respiratory compromise the carbon dioxide rises before the oxygen falls, so a normal saturation does not exclude ventilatory failure, and the assessment rests on the breathing effort, the cough, and the carbon dioxide. [10]

The management is the prevention bundle of the consensus statement: airway clearance with chest physiotherapy and a cough-assist, antisialogogues such as glycopyrrolate and botulinum toxin for the sialorrhoea, full immunisation, and polysomnography-guided continuous positive airway pressure for obstruction or non-invasive ventilation for hypoventilation. The candidate closes by coordinating the multidisciplinary team and a clear emergency and advance care plan, and by counselling the family honestly that the underlying condition is not cured but that treating all three domains together improves comfort, energy, and length of life.
