Figure 3From: Randomized comparison of the i-gel™, the LMA Supreme™, and the Laryngeal Tube Suction-D using clinical and fibreoptic assessments in elective patients Flow chart indicating the number of failures and the supraglottic airway device used as the secondary device, including the corresponding success rates. 1st or 2nd success = insertion success rate for the first or the second insertion attempt. i-gel™; LMA-S = LMA-Supreme™; LTS-D = Laryngeal Tube Suction-D; TT = tracheal tube. Below the horizontal line is the summary for each device (intention-to-treat plus rescue device).Back to article page
