Risks	Possible ways to mitigate
Gastric inflation Pulmonary aspiration of gastric contents	Careful case selection Limiting controlled ventilation to low pressures via well positioned devices Use pressure controlled ventilation to limit peak airway pressure Correct use
Difficulty or failure in placement and ventilation	More information

Risks	Possible ways to mitigate
Gastric inflation Pulmonary aspiration of gastric contents	Careful case selection Limiting controlled ventilation to low pressures via well positioned devices Use pressure controlled ventilation to limit peak airway pressure Correct use
Difficulty or failure in placement and ventilation	Good technique Limitation of ventilating pressures
Mucosal trauma, oedema and necrosis of the uvula, oedema of the tongue Dental trauma during insertion and removal Various nerve injuries including recurrent laryngeal, hypoglossal and lingual nerves	More information

Difficulty or failure in placement and ventilation	Good technique Limitation of ventilating pressures
Mucosal trauma, oedema and necrosis of the uvula, oedema of the tongue Dental trauma during insertion and removal Various nerve injuries including recurrent laryngeal, hypoglossal and lingual nerves	Pre-operative assessment Good insertion technique Maintaining low intracuff pressure after insertion (and adjusting at 20-30 min if using nitrous oxide)
Epiglottic downfolding or oedema causing airway obstruction	Good insertion technique
