Dysphagia and Aspiration Risk After Prolonged Intubation
A 74-year-old woman is day 4 after 11 days of mechanical ventilation for pneumonia. She has a tracheostomy (size 8, cuff inflated) and is on 2 L/min oxygen via the trach. She is alert, follows commands, and has a weak, breathy voice. She coughs after small sips of water during a nurse's informal trial, and her oxygen saturation drops from 96% to 91% within a minute. She has lost 6 kg and her family is anxious about her not eating. The physician asks whether she can start oral feeding today.
1. What is your risk assessment, and what does the desaturation and cough suggest?

This is a high-risk dysphagia picture: prolonged intubation (11 days) is a major risk factor for laryngeal injury, reduced laryngeal sensation, and delayed swallow triggering. The cough after water and the desaturation from 96% to 91% suggest possible penetration/aspiration with a protective cough, but desaturation can also reflect fatigue, poor breath support, or a reflex response.
Key points:
- A cough is a protective sign, but it does not exclude aspiration; silent aspiration is common after prolonged intubation.
- The inflated cuff and trach alter airflow and subglottic pressure and may impair cough effectiveness and laryngeal elevation.
- Weight loss (6 kg) and family anxiety create pressure to feed, but safety comes first; a single informal trial is not a valid basis for a feeding decision.
Conclusion: do not start unrestricted oral feeding today; recommend a formal instrumental assessment.
2. What assessment and management steps do you recommend, and how do you address the family's concern?

Assessment:
- Instrumental swallow study (FEES preferred here because it can be done at the bedside with the trach in place; VFSS if transport is safe) to identify aspiration, residue, and the effect of cuff deflation or a one-way valve.
- Review trach management with the team (cuff deflation trial, speaking valve, suctioning) because these affect swallowing and secretion management.
- Reassess oxygenation and fatigue during trials; keep trials short.
Management:
- NPO or restricted oral intake until instrumental results are available; maintain nutrition via the existing enteral route.
- If safe textures are identified, start with small volumes of the safest consistency under supervision, with positioning and compensatory strategies, and monitor saturation.
- Daily re-assessment, because post-extubation dysphagia often improves.
Family: explain in plain terms that the cough and oxygen drop are warning signs, that we are not giving up on eating, and that a bedside test today will let us feed her safely sooner. Offer a written plan and a contact person.
