Tracheostomy care and emergencies: Case

This is a technology-dependent child with an established, mature tracheostomy who has presented with a blocked tube, the everyday tracheostomy emergency. Two features are reassuring and instructive. His mother is trained, has already worked through part of the algorithm by suctioning and oxygenating the stoma, and has brought his emergency bag, and his tracheostomy is well established, so the stoma tract is mature and reinsertion is far safer than in a fresh stoma. The case tests emergency management, home care, and the eventual path to decannulation. [1]

Clinical findings

The key findings are the acute distress and duskiness of a child with a tracheostomy, which define a tube emergency, and the partial response to suction and stoma oxygen, which points to a blocking secretion problem rather than complete displacement. The candidate should describe completing the algorithm in the emergency department: giving oxygen to both the face and the stoma, removing any speaking valve or inner cannula, passing a suction catheter to confirm patency and clear the plug, and being ready to remove and replace the tube from the go-bag if it cannot be cleared. [1]

The candidate should recognise the value of the trained parent and the emergency bag, and use them. The go-bag should contain a same-size and a smaller tracheostomy tube, suction equipment and catheters, lubricant, and the child's written emergency plan naming his tube. Confirming that his emergency equipment is present and correct, and listening to a mother who knows the tube intimately, is often the fastest route to safety, particularly in a regional department where staff may be less familiar with paediatric tracheostomies. [2]

Management

After clearing the plug and stabilising the child, management addresses why the tube blocked and how to prevent recurrence. Recurrent mucus plugging almost always reflects inadequate humidification, so the candidate should review the child's humidification at home, his hydration, and his suctioning routine and technique. The tube change schedule and the condition of the stoma should be checked, and if plugging is recurrent the humidification system and family technique should be formally reassessed rather than the events treated as isolated bad luck. [1]

The candidate should outline the child's ongoing multidisciplinary care: respiratory medicine, ENT, community nursing, and allied health, coordinated through a tertiary centre with local support in his regional town. Because he no longer needs ventilation, the candidate should raise the prospect of decannulation assessment, describing airway endoscopy to confirm patency and exclude granulation, downsizing and capping trials to confirm he tolerates the natural airway, and the debated role of a sleep study before the tube is removed. Any decannulation would occur in a monitored setting at the tertiary centre. [1]

Complications and follow-up

The candidate should discuss the complications this child is at risk of: acute tube blockage and accidental decannulation as the lethal events, and chronic problems including granulation tissue at the stoma and in the airway, stomal infection and skin breakdown, tracheitis, and, after eventual decannulation, a possible persistent tracheocutaneous fistula. Recurrent bleeding on suctioning or difficult tube changes should prompt airway endoscopy to look for granulation rather than repeated force. [3]

Follow-up centres on prevention and family support. The candidate should confirm the family remains competent and confident, that the go-bag is complete and travels everywhere with the child, and that humidification and suctioning at home are reliable, which in a regional setting means confirming adequate power supply and community nursing support. The child needs a clear escalation plan and a low threshold for retrieval to the tertiary centre, and the candidate should acknowledge that most mortality in tracheostomy-dependent children reflects the underlying disease while the preventable tube-related deaths are averted precisely by this preparation.
