Flashcards in 6 - ENT - Upper airway - Obstruction - Emergency airway management Deck (10):
1

when would cricothyroidectomy be done

-obstruction is at or above level of larynx, so endotracheal intubation not possible
-severe maxillofacial trauma

2

3 dif methods for cricothyroidectomy

needle
cricoidotomy kit
surgical

3

describe needle method of cricothyroidectomy

large bore canula into cricothyroid membrane at 45 degrees (sup)
give oxygen through cannula

4

describe surgical method of cricothyroidectomy

usually only >12y
incision in cricothyroid membrane, parting of tissue, insertion of short ET tube

5

Complications of cricothyroidectomy

laryngeal/tracheal trauma
recurrent laryngeal nerve damage
haemorrhage
oesphageal perforation

6

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

7

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

8

Trachy - role of speaking valve + reservoir

speaking valve - allows air to enter during inspiration + closes on inspiration
reservoir- allows cuff pressure to be checked

9

early complications of Trachy

blockage
displacement
surgical emphysma
pneumothorax
infection
dysphagia

10

late complications of Trachy

tracheal erosion or stenosis
tracheo oesophageal fistula
persistent tracheocutaneous fistula
tracheitis
