A clinical comparison of the Flexiblade and Macintosh laryngoscopes for laryngeal exposure in anesthetized adults.

The Flexiblade is a laryngoscope with a flexible blade. To evaluate the efficacy of the Flexiblade compared with the classic Macintosh laryngoscope, we performed a clinical study in 200 paralyzed patients undergoing elective surgery requiring general anesthesia and endotracheal intubation. Direct laryngoscopy was performed with a size 3 Macintosh laryngoscope and the Flexiblade, with and without activation of the lever.
