A middle-aged female patient was scheduled for an elective operation on her hand. She had undergone several general anaesthetics in the past when a cLMA had been used without documented problems. She had a Mallampati score of three and a thyromental distance of 6cm. Face mask ventilation with an oropharyngeal airway was extremely difficult. A pLMA was inserted, but ventilation was not possible. A size four cLMA was also tried with the same result. A size four i-gel® was then inserted. This immediately provided unobstructed ventilation and stable oxygenation saturation of 98%. The authors commented that ‘the i-gel®’s role in difficult airway management remains to be established, but its ease of insertion, short wide airway tube and good airway leak pressures make it a potentially useful airway device in cases of difficult mask ventilation.’
