Randomized Controlled Trial Comparative Study
Comparison of plastic and metallic single-use and metallic reusable laryngoscope blades: a randomised controlled trial.
Plastic single-use laryngoscope blades have been found to increase the difficulty of intubation. Metallic single-use blades may represent an alternative. ⋯ The rates of failed intubation at first laryngoscopy were similar in the metallic reusable and metallic reusable groups, but greater in the plastic single-use group.

Comparative Study
A comparison of the AMBU ISCOPE and Macintosh laryngoscopes: first experience with a new device for tracheal intubation: a manikin study.
Video laryngoscopes achieve laryngeal visualisation through indirect imaging using video cameras that look around the curve of the tongue. The new AMBU ISCOPE intubation device combines features from the laryngeal mask airway with video laryngoscopy enabling visual control of tracheal intubation without the use of a stylet. ⋯ Tracheal intubation time was significantly longer in trainees using the AMBU ISCOPE intubation device compared to a Macintosh laryngoscope, but with a difference of only 8 s. Laryngeal visualisation was significantly better using the AMBU ISCOPE device, but success rates for intubation were the same.
