Use of a ProSeal laryngeal mask airway and a Ravussin cricothyroidotomy needle in the management of laryngeal and subglottic stenosis causing upper airway obstruction.
We report the successful use of a ProSeal laryngeal mask airway (PLMA) as a dedicated airway to allow fibre-optic inspection and passage through a tightly stenosed glottic and subglottic lesion, before fibre-optic-guided transtracheal placement of a Ravussin needle and jet ventilation. The described technique avoided both tracheostomy and the potential of 'seeding' the tumour by passage of the needle through the mass. The PLMA may be a useful 'dedicated airway' and has several advantages over the classic LMA(double dagger) and intubating LMA when used for this purpose. These include improved airway seal and reduced risk of aspiration. Four other cases of use of the PLMA as a dedicated airway during management of difficult airways are discussed. double daggerLMA is the property of Intavent Ltd.
