High success rate of fiberscope-monitored intubation via a supraglottic airway device BlockBusterTM in good device positioning: A prospective observational study

Upon arrival in the operating room, standard multi-channel monitors including non-invasive blood pressure, electrocardiograph, pulse oxygen saturation, and end tidal carbon dioxide (ETCO2) waveforms were applied throughout the procedure. The following data were recorded: (1) Attempts and duration needed to insert the SAD BlockBusterTM; (2) Fiberscopic check of the SAD position by Brimacombe J scoring system[3]; (3) The success rate of fiberscope-monitored intubation via the SAD BlockBusterTM; (4) Attempts and duration needed to intubate the BTT; and (5) Airway trauma and complications were recorded post-operatively. The sex ratio (female/male) was 70/36, the time of SAD BlockBusterTM insertion was 17.0 ± 2.9 s, and the success rate of gastric tube insertion was 99.1% (105/106) [Supplementary Table 1, http://links.lww.com/CM9/B845]. The higher success rate of intubation and less intubation time via SAD BlockBusterTM may be due to its unique design, such as a short one curve airway channel with large oval cavity and a circular exit with ramp, a modified inflatable cuff [Supplementary Figure 2, http://links.lww.com/CM9/B845].
