✦ Synopsis

The Flexiblade is a laryngoscope which has a ‘flexible’ blade. The ‘front’ half of the blade can be moved in an anterior direction during laryngoscopy, enhancing the view of the glottis. The degree of movement can be controlled with the lever. We studied 200 ASA 1 and 2 adult patients requiring tracheal intubation and the patients acted as their own controls. The view of the larynx was improved in 93% of the cases when the vocal cords were not completely visible at laryngoscopy with the lever in the neutral position. Ninety‐seven per cent of patients with a Cormack and Lehane grading of 2 at normal laryngoscopy were transformed to grade 1 when the lever of the Flexiblade was depressed and 84% of cases with a grading of 3 were transformed to grade 2 or 1. In four patients, there was deterioration in the view of the cords: three patients with grade 1 were transformed to grade 2 and one with grade 2 to grade 3. There was no improvement in one case with grade 2 and three with grade 3.
