The intubating laryngeal mask Fastrach™ is considered a gold standard for blind intubation as well as for fibreoptic guided intubation via a laryngeal mask. Recently, a single use version of the mask has been introduced. The Fastrach single use laryngeal mask is beng compared to the new, low-priced single use intubating laryngeal mask Ambu Aura-i™.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | success rate of blind intubation | overall success rate of blind tracheal intubation within two attempts using either the FASTRACH™ laryngeal mask or the Ambu Aura-i™ laryngeal mask | through study completion; time frame for individual study patient: two attempts of blind tracheal intubation peri-interventional, time maximum of 300 seconds | |
Secondary | influence of tracheal tubes | influence of success rates of blind tracheal intubation using different tracheal tubes (Rüsch or LMA-ETT) | through study completion; time frame for individual study patient: two attempts of blind tracheal intubation peri-interventional, time maximum of 300 seconds | |
Secondary | equivalence of the laryngeal masks regarding fibreoptic visualisation | fibreoptic control of laryngeal mask placement (Fastrach and Aura-i); the position of the larynx relative to the laryngeal cuff and mask-aperture is visualised and categorised as "correct", "lateral deviation", "epiglottic downfolding" or "not assessable"; additionally, the view on the larynx comparable to Cormack/Lehane score is recorded | through study completion; after placing the laryngeal mask and checking for airway leak pressure, fibreoptic visualisation is performed within 60 seconds | |
Secondary | subjective handling score | subjective handling score for the two compared laryngeal masks, rated as excellent (1) - poor (4) | through study completion; the handling of the laryngeal masks during the first placement attempt within 60 seconds; directly after placing laryngeal masks and before fibreoptic visualisation, the subjective handling score is documented as above | |
Secondary | differences in airway leak pressure | differences in airway leak pressure (ALP) of the two compared laryngeal masks, in cm H2O; presence of audible leakage as well as the absence of corresponding pressure increase on the monitor recorded by setting the APL valve to 40cm H2O, and fresh gas flow at 3l/min | through study completion; right after placing the laryngeal mask and checking for correct positioning, ALP is documented within 60 seconds | |
Secondary | incidence of postoperative sore throat and hoarseness | incidence of postoperative sore throat and hoarseness as well as difficulty swallowing as reported by the study patients ("none", "moderate", "severe") | patient interview 24 hours post procedural |
