Consider one of the following op�ons :1. Preferably wake up the pa�ent2. Con�nue anaesthesia using the SAD only if considered safe for the pa�ent, keeping in mind the risk of aerosolisa�on 3. Tracheostomy and tracheal intuba�on through SAD are not preferred

Wake up the pa�ent

l Use second genera�on SAD

l Maximum two a�empts (only if SpO ≥ 95%)2

l Gentle mask ven�la�on between a�empts (if SpO2 95%) withl two-hand two-person technique and op�mal mask fit*l Consider changing size or type of SAD

l Maintain depth of anaesthesia and op�mal neuromuscular blockade

l Con�nue nasal oxygen using O flow at 5 L/min2

l Ensure neuromuscular blockadel Final a�empt at gentle mask ven�la�on* using op�mal technique

l Con�nue nasal oxygen using O flow at 5 L/min and efforts 2

Management of Unan�cipated Difficult Tracheal Intuba�on in Adults during the COVID-19 Pandemic

STEP 1: Laryngoscopy and tracheal intuba�onUnable to intubate during first a�empt at direct / videolaryngoscopy

STEP 4 : Emergency cricothyroidotomy

STEP 3: Rescue face mask ven�la�on

STEP 2: Insert SAD to maintain oxygena�on
