- Tracheostomy is an airway that is inserted subglottically through neck tissues directly into the trachea.
- Surgical Tracheostomy involves dissection and incision of trachea under direct vision.
- Percutaneous Tracheostomy involves Seldinger technique and dilatation of trachea between rings.
- PDT is percutaneous dilational tracheostomy
- airway obstruction
- inability to protect the airway (e.g. from aspiration)
- access for pulmonary toilet
- facilitate weaning from prolonged mechanical ventilation
- patient or family refusal
- paediatric patient (< 16 years)
- midline neck mass
- uncorrected coagulopathy or platelet dysfunction
- infection at site
- suspected or known difficult intubation
- poor respiratory function: FiO2 > 0.6, PEEP > 10
- difficult anatomy – obese/short neck/neck distortion
- unstable c-spine or c-spine immobilisation (cervical fusion/instability, rheumatoid arthritis)
- assess for appropriateness of PDT
- IV access
- emergency re-intubation gear
- standard monitoring (including ETCO2)
- personnel: surgeon, anaesthesia + bronchoscopist (all with adequate experience or supervision)
- GA + LA
- pull ETT back to cords (?LMA use)
- sterile technique
- insert percutaneous tracheostomy
Different techniques of PDT are discussed in more detail here.
- if accidental decannulation takes place in first 72 hours -> oral intubation
ADVANTAGES OF PDT
- reduced sedation requirement (greater comfort than oro-tracheal intubation)
- airway protection while unconscious
- allows gradual weaning of ventilatory support (reduced work of breathing)
- enhanced communication (written or phonation)
- decreased ICU mortality
- enhanced nursing care (mouth care and mobility)
- ease of replacement of tracheal tube
- can facilitate transfer to the ward
DISADVANTAGES/COMPLICATIONS OF PDT
- requirement for a surgical procedure
- See Tracheostomy complications
- hang over from when all tracheostomies were surgically inserted (window cut into trachea) -> downsizing would allow gradual closure of tract and was less likely to result in fistula.
- no real place in percutaneous tracheostomies
- advantages: improved swallow
- disadvantages: increased work of breathing, repeat trauma to airway, not really needed
FENESTRATED TRACHEOSTOMY TUBES
- for awake alert patients who want to phonate
- must have no risk of aspiration
- need to deflate cuff and insert a fenestrated inner
- prevents disuse atrophy of the vocal cords
- must warn patients that they will have sensation of air coming up through vocal cords
- may allow cough into mouth
- often suboptimal on non-surgical wards
- patient are by definition high risk patients
- if managed by outreach teams can improve outcomes (doctor, nurses, SLT, physio) – TRAM team
- emergency and replacement equipment should be at the bedside at all times
WEANING AND REMOVAL
- Some consider it once the patient has had the tracheostomy tube plugged for 48 hours or more, whereas others consider it once a speaking valve is tolerated
- Weaning may be achieved with a number of different pathways including direct removal of the TT, routine downsizing, changing to a cuffless TT, use of fenestrated TT, spigotting/capping/corking or use of a speaking valve.
- no evidence for any specific pathway
- approach tends to be clinician / institution specific
- absence of airway obstruction (tracheal stenosis or granulation tissue) according to nasoendoscopy and/or clinically by tube occlusion with cuff down
- sputum burden decreasing (2-4 hourly)
- patient co-operative
- good cough
- patient able to protect upper airway from aspiration
- no longer requires mechanical ventilation
