Further study details as provided by University Hospital Inselspital, Berne:

Primary Outcome Measures:
  • First attempt visualized blind intubation success rate [ Time Frame: how many seconds needed ]

Secondary Outcome Measures:
  • Overall intubation success rate [ Time Frame: how many seconds needed ]

Estimated Enrollment: 80
Study Start Date: October 2012
Study Completion Date: August 2014
Primary Completion Date: August 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Ambu Aura-i
Procedure: Intubation
visualized blind intubation
Active Comparator: AirQ
Procedure: Intubation
visualized blind intubation

Detailed Description:
After induction of anesthesia, one of the 2 laryngeal masks (Ambu or AirQ) is going to be inserted. Following this, a tracheal tube is mounted on a fiberoptic scope with the tip of the scope behind the tip of the tube. This way, the tracheal tube is not guided by the scope, but the scope visualizes the course of the tracheal tube in the laryngeal mask and the glottic opening as if the tracheal tube was advanced blindly: Visualized blind intubation
