Tracheostomy Flashcards
what is tracheostomy
it is a surgical opening in the anterior wall of the trachea to facilitate ventilation/ inspiration. surgical- patients lies in a supine position and Cx placed in ext, with a 2-3cm incision is made (made between 2-4 tracheal rings), percutaneous- placed under guide wires (placed in between first and second tracheal rings) which then separates the trachea to allow insertion- doesn’t require surgery
indications
to maintain an airway, to bypass possible or actual upper airway obstructions, protections of trachea-bronchial tree, to assist in removal of bronchial secretions, prolonged need for artificial ventilation, to facilitate weaning from a ventilator, total laryngectomy, reduces anatomical dead spaces- makes breathing easier
pros of tracheostomy
increased patient mobility/ comfort, ease for suctioning, aids weaning from mechanical ventilation, decreases anatomical dead space, enables/assist communication, enables oral intake, decreased risk of infection
cons of tracheostomy
blocked/displaced tubes, infections, long term tracheal damage, aspiration risks, psychological effects, scar formation, long term vocal cord damage
features of tracheostomy tubes
shaft- airway bit, flange- bit around the outside, cuff- at end of pillow balloon, blown up to block airway, pillow balloon- where air is ejected, 15mm connector, inner tube
attachments- speaking valves, caps and spigots
types of tubes
single cannula- one tube, double cannula- outer and inner part, fenestrated (wholes in tubes, aids in weaning)/non-fenestrated, cuffed/un-cuffed, adjustable flanged
effects of tracheostomy on humidification
drying of secretions, loss of normal filtering systems, reduced mucocillary transport, reduced airway pressure
humidification
hydration, warm/cold water systems, nebulisers, saline installation, swedish nose/thermovent, buchanan bibs
what is weaning
a planned sequential process that allows early return from a dependant stat to independence
weaning- beginning the process
mechanical ventilation- CPAP- trachy mask-deflate cuff-speaking decantation cap- decantation
importance of weaning and decannulation
decreased risk of complications, decreased stress, psychological boost for patients, may promote speed of recovery, cost savings, decreased dependency of patient on MDT
criteria for tracheostomy weaning
primary cause resolved, adequate nutritional state, adequate sleep, psychological support, able to protect airways- adequate ventilatory reserve- spontaneous breathing off ventilator for 24-48hours, O2 <40%, manageable secretions- CVS stable
failed decannulation
decreased saturations, changes in HR (ECG), increased RR, increased WOB, inability to cough and expectorate, fatigue, stridor
continuation of tracheost
upper airway obstruction, severe neurological deficit, inability to maintain own airway, persistent severe aspiration, severely reduced lung compliance
tube changes- consider
timing, type of procedure, type of tube, progression of weaning, patients medical conditions, resus knowledge, emergency equipment, 2 operators, patient consent (where possible), competence
