Both the conventional direct laryngoscopy and the D-Blade were used in 15 consecutive patients with normal airways during routine induction of anesthesia. The D-Blade was also used as a rescue device in 20 of 300 consecutive patients when conventional direct laryngoscopy failed.
The study found the device performed as well or better than a traditional blade in routine intubations. In tests where the authors had a poor view with the traditional blade, the D-BLADE improved the view significantly, suggesting it could be valuable as a rescue device.
