6 - ENT - Upper airway - Obstruction - Emergency airway management Flashcards
when would cricothyroidectomy be done
- obstruction is at or above level of larynx, so endotracheal intubation not possible
- severe maxillofacial trauma
3 dif methods for cricothyroidectomy
needle
cricoidotomy kit
surgical
describe needle method of cricothyroidectomy
large bore canula into cricothyroid membrane at 45 degrees (sup)
give oxygen through cannula
describe surgical method of cricothyroidectomy
usually only >12y
incision in cricothyroid membrane, parting of tissue, insertion of short ET tube
Complications of cricothyroidectomy
laryngeal/tracheal trauma
recurrent laryngeal nerve damage
haemorrhage
oesphageal perforation
Indications for a tracheotomy - 6
- bypass UAO
- prevent UAO due to swelling after H+N surgery
- prevent aspiration in neuro condition
- allow respiration following laryngectomy
- protect lungs from UA bleeding
- in long term mechanical ventilation
Trachy - role of cuff + fenestration
cuff - allows seal for ventilation, prevents aspiration from above level of cuff
fenestration - allows air to pass through on expiration into larynx for speech
Trachy - role of speaking valve + reservoir
speaking valve - allows air to enter during inspiration + closes on inspiration
reservoir- allows cuff pressure to be checked
early complications of Trachy
blockage displacement surgical emphysma pneumothorax infection dysphagia
late complications of Trachy
tracheal erosion or stenosis
tracheo oesophageal fistula
persistent tracheocutaneous fistula
tracheitis
