Intubation through the LMA-Supreme: a pilot study of two techniques in a manikin.

The LMA-Supreme is a single-use disposable laryngeal mask that combines features of several laryngeal mask airways in one device. The primary aim of our study was to compare ease of use and operator preference for fibreoptic-aided intubation through the LMA-Supreme using an Aintree Intubating Catheter or Arndt Airway Exchange Catheter Set. Twenty participants experienced in fibreoptic-aided intubation performed a total of 40 intubations on an AirSim airway manikin through a #4 LMA-Supreme. Intubation using the Arndt Airway Exchange Catheter Set was easier than with the Aintree Intubating Catheter. Half of the participants preferred Aintree Intubating Catheter-assisted intubation, citing fewer steps and faster performance as the reasons. All 20 (100%) Arndt Airway Exchange Catheter Set-assisted intubations and 18/20 (90%) of Aintree Intubating Catheter-assisted intubations were successful. Aintree Intubating Catheter and Arndt Airway Exchange Catheter Set-assisted intubations can be performed quickly, successfully and with minimal difficulty through the LMA-Supreme by experienced operators. While the Arndt Airway Exchange Catheter may be easier the Aintree Intubating Catheter is faster. [ABSTRACT FROM AUTHOR]
