The operation enters the trachea through the second and third rings, never the first ring or the cricoid (the subglottis stenoses), and its feared late complications are tracheal stenosis at the stoma or cuff site, tracheo-innominate artery fistula presenting as a herald bleed around the first to third week, and tracheo-oesophageal fistula from cuff-plus-tube pressure necrosis. Cuff pressure stays below about 25 cm of water to protect the tracheal mucosa; decannulation is a staged test — downsizing, corking or capping for 24–48 hours including sleep — not an abrupt event. ## What you must remember - Indications in three groups: upper airway obstruction (bilateral cord palsy, deep neck infections, tumours, trauma, angio-oedema, foreign body), prolonged ventilation (generally beyond about a week of intubation or anticipated long ventilation), and protection or toilet — impaired consciousness, aspiration, major head and neck surgery. - Surgical anatomy: horizontal skin crease incision, thyroid isthmus divided or retracted, trachea opened at the second and third rings; the first ring and cricoid are preserved to avoid subglottic stenosis; percutaneous dilational tracheostomy (Ciaglia) with bronchoscopic guidance is the ICU alternative. - Emergency surgical airway in adults: cricothyroidotomy through the cricothyroid membrane, converted to a formal tracheostomy later; in children, cricothyroidotomy is contraindicated — needle cricothyroidotomy with jet ventilation or a formal tracheostomy is performed. - Tube vocabulary: cuffed versus uncuffed (children are usually managed uncuffed), fenestrated tubes for speech, cuffed tubes with low-pressure cuffs for ventilation, and the inner cannula — present in most adult tubes and cleaned or replaced to prevent obstruction. - Daily care: heated humidification (the single most important measure against crusts), sterile suction at safe depth without touching the carina... passed just beyond the tube tip, inner-cannula cleaning several times daily, stoma cleaning with saline, and dressing changes keeping the wound dry. - Cuff pressure kept below about 25 cm H2O (checked with a manometer, and the cuff deflated when the airway is protected) to prevent mucosal ischaemia leading to stenosis, malacia and fistulae; overinflation is the common iatrogenic sin. - Complication timeline: immediate — haemorrhage, apnoea, air embolism, recurrent laryngeal injury; early (first week) — tube blockage, accidental decannulation (before the track matures, the tube may be impossible to reinsert — re-intubate if in doubt), surgical emphysema, pneumothorax, pneumomediastinum, infection; late — tracheal stenosis, tracheo-innominate artery fistula, tracheocutaneous fistula, tracheo-oesophageal fistula, dysphagia and difficult decannulation. - Tracheo-innominate fistula: a "herald" small bleed days to weeks after tracheostomy, then catastrophic haemorrhage — managed by hyperinflating the cuff (or finger compression of the artery against the manubrium through the stoma) and immediate surgical exploration; it is why any significant tracheostomy bleed is an emergency. - Decannulation: medical stability, effective cough, tolerance of capping for 24–48 hours including sleep, then removal with an airtight dressing; the smallest-tube-first downsizing path and occlusion testing reduce failure. ## Walking through the first week of care Day zero, theatre or ICU: the tube is secured with ties around the neck (one-finger slack) plus sutures; a chest radiograph follows for position and pneumothorax. The first tube change waits until the track matures — commonly about 3 to 7 days — and is done by someone who can manage a failed reinsertion. From hour one, humidified oxygen runs constantly; suction is performed sterile, briefly, and only as needed, passing the catheter just beyond the tube tip, limiting passes and duration to avoid trauma and desaturation. The inner cannula is checked, cleaned or swapped on a schedule — most sudden obstructions are a crust sitting on an uncleaned inner tube. Day two or three, the patient on a ventilator: check cuff pressure with the manometer at each shift, aiming under 25 cm H2O and the minimum leak-free volume; once spontaneous breathing protects the airway, deflate intermittently and work toward cuffless or fenestrated tubes. Swallowing is impaired by the tube and cuff — assess before oral feeding, keep the cuff deflated when safe, and sit the patient upright for meals. Day seven onward, weaning: downsize the tube (8 to 7 to 6), then cork or cap a fenestrated or uncuffed tube through waking hours, extending to the full 24–48 hours including sleep; if the patient sleeps comfortably capped with an adequate cough, remove the tube, dress the stoma airtight and let it close over days. A stoma still leaking after a week of decannulation is a tracheocutaneous fistula needing closure. Throughout, watch for the two alarms — sudden bleeding from the tube (think innominate fistula: act, do not observe) and an abrupt inability to pass a suction catheter (obstructed or displaced tube: remove the inner cannula, attempt bag ventilation, and be ready to re-intubate orally). ## Where students slip Examiners' first probe is anatomy: which rings (second and third) and which structure is spared (cricoid and first ring — subglottic stenosis is the price of violating them). The second is the emergency edge: bleeding around day 10 to 21 is a herald bleed until excluded — the expected answer is cuff hyperinflation and theatre, not observation. The third is the decannulation process — candidates say "just remove it", losing the staged capping-for-48-hours answer including sleep. Also commonly confused: cricothyroidotomy is the adult emergency surgical airway but is avoided in children (subglottic cricoid injury); and the purpose of the inner cannula (cleanable lumen preventing obstruction) versus the fenestration (airflow past the tube for speech). Finally, humidification as the answer to "how do you prevent crusts and blockage" is the pure viva mark. ## Frequently asked questions ### At which tracheal rings is a tracheostomy performed and why is the first ring spared? Through the second and third rings; violating the cricoid or first ring damages the subglottis, the narrowest and least forgiving segment, causing subglottic stenosis. ### What is the maximum safe cuff pressure and why? About 25 cm H2O or below — higher pressures compress tracheal mucosal capillaries, causing ischaemic ulceration, stenosis, malacia and fistula formation. ### What is a tracheo-innominate artery fistula and how does it present? Erosion of the innominate artery from tube or cuff pressure, presenting weeks after tracheostomy with a small herald bleed preceding catastrophic haemorrhage; managed by cuff hyperinflation, digital compression against the manubrium and immediate surgery. ### How is decannulation performed safely? By staged downsizing and capping or corking the tube for 24–48 hours including sleep, confirming an effective cough and stable airway before removal, then an airtight stoma dressing. ### Why is humidification essential in tracheostomy care? The bypassed nose no longer warms, filters and humidifies inspired air; dry air causes crusted secretions that can occlude the tube, so heated humidification with sterile suction and inner-cannula care forms the core of daily management.
