Assessing the incidence of ‘can see, cannot intubate easily’ during routine use of C‐ <scp>MAC</scp> videolaryngoscopy

Assessing the incidence of `can see, cannot intubate easilyd uring routine use of C-MAC videolaryngoscopy Evidence of benefit of videolaryngoscopy over direct laryngoscopy is widespread with increasing recommendations for routine use [1, 2].Videolaryngoscopy using Storz C-MAC reusable videolaryngoscopes (Karl Storz Endoscopy UK Ltd., Slough, UK) has been default practice throughout our hospital since 2017.Although hyperangulated blade videolaryngoscopy improves laryngeal view [1], many authors state that this does not improve ease of tracheal intubation, i.e. `can see, cannot intubate easily.We examined a database of adult videolaryngoscopic tracheal intubations to explore this.Statistical analysis was done with SPSS (version 30, IBM, Armonk, NY, USA).Our data collection method has been published previously [3].Anaesthesia and critical care staff in our UK district general hospital were asked to submit data from all tracheal intubations to a local database.Data relevant to the current analysis included: location; device used; grade of intubator; device experience; best grade of laryngeal view; number of tracheal intubation attempts; and need for a second operator.The Cook classification of laryngeal view was used: `easy(vocal cords visible, modified Cormack and Lehane grade 1 and 2a); `restricted(vocal cords not visible, epiglottis liftable, grades 2b and 3a); or `difficult(epiglottis not liftable or not visible, grades 3b and 4) [4].Consultants, Specialty/Associate Specialist doctors and Specialist Registrars were deemed senior intubators and all others junior intubators.We included cases with documented `easyvideolaryngoscopic view
