Airway management

Miscellaneous

Tools used in management/intervention (Artificial airway)

Infraglottic airway devices

Infraglottic acess (CTR)

Retrograde intubation

Tracheostomy

Cricothyroidotomy

Supraglottic access

Fiber optic devices

Endotracheal tube (ETT)

Supraglottic airway devices

☻Others (PLS!)

Streamlined pharynx airway liner

Laryngeal tube airway

Perilaryngeal airway

☻Other supraglottic airways similar to LMA (SAI)

Intubating laryngeal airway

Ambu laryngeal mask

Soft seal LM

☻Laryngeal mask airway (LMA) family (PF2UC2)

LMA Ctrach

LMA Classic

LMA unique

LMA fastrach

LMA flexible

LMA Proseal

Nasopharyngeal airway (NPA)

Oropharyngeal airway (OPA)

Face mask

Methods of assessment

3.Tests used in assessment

d) Other spaces

Thyroid to hyoid distance (Normally 2 fingers)

Hyoid to mental distance (Normally 3 fingers)

Inter-incisor distance (Normally 3 fingers)

c) SM spaces

Sterno-mental space

Critical distance is 12.5cm

Thyro-mental space (Normally More than 6.5cm/3fingers)

The blade used during laryngeoscope is called Miller-blade

if less than 6cm => considered difficult intubation

b) Atlanto-occipital joint

H&N extension (Normally 35ْ )

a) Oropharynx

Mallapati score

2.Physical examination (From above downward) Face/Teeth,tongue/mandibule/neck

Neck(SOLD): - Short neck - Obesity - Limited neck movement - DOorso-cervical fat pad

Mandibule: - Limited protrusion of mandibule - Limited opening of mouth

Teeth: - Malocclusion overbite of anterior teeth Tongue: - Large tongue

Face (Any facial deformities) : - Receding chin - Smal SM space

1.History taking(AP3CD/TS)

Snoring or sleep apnea

Tmporo-mandibular joint (TMJ) dysfunction

Dentures or loose teeth

Crvical spine abnormalities - Cervical spondylosis or ankylosing spondylosis

Previous neck surgery - Tracheostomy, thyroidectomy Previous airway problems - difficult intibations, stenosis, reaction to anaesthesia Previous Hemi-mandibulectomy

Introduction

2.Steps of airway management

2.2. Intervention

b)Simple maneuvers and airway adjunct devices

a) General guidelines

2.1. Assessment(What to assess?)

b) assessment of airway protection

a) Assessment of airway patency

1.What is airway?

It includes nose/mouth, pharynx, larynx and trachea

It's the normal passage way for air entry/exit in human for good gas exchange @ the lungs
