Initial evaluation of a new optic laryngoscope blade.
We report on a new optic laryngoscope blade that provides two views of the larynx during tracheal intubation. The availability of an alternative direct view of the larynx may improve the ability of anesthesia providers to observe the tracheal tube passing through the vocal cords when using a Macintosh laryngoscope blade. The optic port improved visualization of passage of the endotracheal tube in obese patients. However, further studies are needed in patients with difficult airways to determine whether this new blade will ease the ability of practitioners to insert a tracheal tube.
