Q

What is a supraglottic airway Igel

A

The igel is a second generation supraglottic airway device used extensively in resuscitation and anaesthesia. Made from a medical grade thermoplastic elastomer, Igel has been designed to create a non-inflatable, anatomical seal of the pharyngeal, laryngeal, and perilayngeal structures while avoiding compression trauma. A gastric channel facilitates venting and active suctioning by inserting an appropriately sized orogastric tube.

Q

How do we know if our airway and breathing is compromised

A

Skin and perfusion: are they pink, cyanosed (blue) , flushed
Facial expressions: are they panicked, anxious, exhausted
Posture: tripod position, clutching at throat
Physical observations: barrel chest (COPD), accessory muscle use, intracostal and suprasternal retractions

Q

What is a OPA

A

An oropharyngeal airway, easily inserted airway management device extending from the lips to the pharynx, that prevents the base of the tongue from falling back and occluding the airway. A flange at the outer opening prevents the device from being inserted or pushed too far into the airway

16
Q

What are the indications of an OPA

A

Maintain airway patency
Bite block for intubated patients

17
Q

What are the contradictions of an OPA

A

Conscious patients
Patients with an intact gag reflex

18
Q

What are the complications of an OPA

A

Airway trauma from OPA placement
Intolerance of OPA requiring removal
Can precipitate vomiting / aspiration in patient with intact gag reflex
Incorrect size or placement can potentially exacerbate airway obstruction

19
Q

What are the colour coded OPA, their sizes and for who

A

Size 10 - red - large male
Size 9 - yellow - adult male
Size 8 - green - adolescent/ adult female
Size 7 - white - child
Size 6 - black - small child
Size 5 - blue - toddler
Size 4 - pink - infant
Size 3 - lilac - neonate

20
Q

Additional information of an OPA

A

Too small an OPA device is ineffective at protecting the airway, while too large a device can press against the epiglottis and obstruct the larynx or precipitate laryngospasm

21
Q

What is a NPA (nasalpharyngeal airway insertion)

A

It is a soft, anatomically designed airway adjunct which is inserted into the nasal passageway to provide airway patency. The flared distal end prevents the device from becoming lost within the nare.
The NPA has advantages over the OPA as it can be used in patients with intact gag reflex, trismus and oral trauma

22
Q

What are the indications of a NPA

A

Potential or actual airway obstruction

23
Q

Are there any contradictions of an NPA

A

No

24
Q

What are the complications of an NPA

A

Airway trauma, particularly epistaxis
Incorrect size or placement will compromise effectiveness
Exacerbate injury in base of skull fracture, with NPA potentially displacing into the cranial vault
Can stimulate a gag reflex in sensitive patients, precipitating vomiting or aspiration

25
Q

Additional information of an NPA

A

An NPA does not protect the patients airway from aspiration
The right nostril is often preferred for NPA insertion given that is typically larger and straighter than the left
A correctly sized NPA will have the flared end resting on the nostril

26
Q

What are the 3 sizes of an NPA

A

Size = 24 - internal diameter (mm)= 6 / external diameter (mm)= 8.1
Size = 28- internal diameter (mm)= 7 / external diameter (mm)= 9.4
Size = 32- internal diameter (mm)=8 / external diameter (mm)= 10.8

27
Q

Why is suctioning important

A

It decreases the risk of aspiration, promotes optimal pulmonary gas exchange and helps prevent nosocomial pneumonia

28
Q

What are the 4 suction adjuncts

A

Y-suction catheter
Yankauer catheter
Meconium aspirator
Ducanto catheter

29
Q

What is a y-suction catheter

A

Used for suctioning endotracheal tubes. Additionally suitable for the suctioning of the patients nares, nasopharynx, oropharynx, stoma, tracheostomy, and airway adjuncts

30
Q

What is a yankauer catheter

A

Rigid plastic catheter with a large suction tip surrounded by a bulbous head used to remove secretions from the oropharynx and external nares

31
Q

What is a meconium aspirator

A

Rigid plastic suction aid used in conjunction with an ETT to aid in the removal of meconium

32
Q

What is the Ducanto suction catheter

A

It is a rigid, high volume suction that can facilitate oropharyngeal clearing in cases of heavy airway soiling during suction assisted laryngoscopy
