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.
