Airway

DOI: 10.1201/9781003159179-2

Nasopharyngeal airway

Description:

• A flexible rubber tube consisting of a smooth angled tip, curved body and flanged end which can be inserted into the nose and extends into the top of the oropharynx
• Sizes range from 2 to 9 (corresponding to diameter in mm) with male adults usually requiring size 7 to 8 and females 6 to 7

Indication:

• Airway adjunct used to provide an airway in patients with an intact gag reflex, trismus or oral trauma
• May be used instead of or in conjunction with an oropharyngeal airway (see Oropharyngeal airway)

Directions of use:

• Select appropriate nostril for insertion (typically right nostril) and apply local anaesthetic spray
• Apply lubricant to tube and insert with bevel facing the nasal septum
• Advance along the septum horizontally, following the natural curvature of the floor of the nasopharyngeal cavity and rotated 90 degrees to lie in the nasopharynx
• Safety pin may be placed behind flange to prevent the advancement of tube
• Correct position can be confirmed by visualising tube tip behind uvula

Cautions and contraindications:

• Major contraindication is base of skull fractures due to possible intracranial placement
• Main complications include epistaxis, ulceration, infection, blockage

Oropharyngeal airway

Description:

• Also known as “Guedel” airway
• Rigid plastic tube inserted into mouth, curved to sit along the roof of the oral cavity and end at the tongue base
• Sizes are colour coded for easy identification (children – 0, 1, 2; adults – 4, 5, 6)

Indication:

• Airway adjunct used to lift the tongue off the posterior pharyngeal wall to prevent airway obstruction in reduced GCS (≤8)
• Also allows for oropharyngeal suctioning

Directions of use:

• Identify the correct size by measuring from the centre of the mouth between the first incisors to the angle of the mandible in an adult
• Ensure no foreign bodies in the oral cavity
• Lubricate the oropharyngeal airway
• Insert into the mouth upside down (reduces risk of pushing tongue back)
• Once tip is around the hard-soft palate junction, rotate 180 degrees and advance until flange at mouth opening
• Confirm airway patency

Cautions and contraindications:

• The main contraindication is use in patients with intact gag reflex (GCS>8)
• Main complications include gagging, vomiting and aspiration; soft tissue trauma to the tongue, palate and pharynx and injury to the teeth

Laryngeal mask airway

Description:

• Supraglottic airway device consisting of flexible plastic tube with an inflatable circular cuff on end which sits above the larynx
• Sizes range from 0 (infant) to 6 (large adult), with typically size 3 or 4 being used for female and male adults, respectively

Indication:

• Ventilation during elective anaesthesia with low risk of aspiration
• Cardiac arrest pre-intubation
• Failed endotracheal tube insertion/lack of available trained staff

Directions of use:

• Select correct size LMA
• Deflate cuff using 20ml syringe
• Lubricate cuff
• Position patient with 15 degree neck flexion and full head extension
• Insert the LMA over the tongue until it reaches the posterior pharyn...
