Comparison of King Vision and McGrath MAC Videolaryngoscopes for Airway Management in Adult Patients Undergoing Elective Surgery: A Prospective Observational Study
Abstract: Background: Videolaryngoscopes have changed contemporary airway practice by offering an indirect view of the glottis without the need to align the oral, pharyngeal and laryngeal axes. The King Vision (a channelled device) and the McGrath MAC (a non-channelled, Macintosh-shaped device) follow two different design philosophies, and a direct head-to-head comparison during routine intubation is therefore of practical value. Aim: To compare the King Vision and McGrath MAC videolaryngoscopes with respect to ease of intubation, glottic visualisation, haemodynamic response and intubation-related complications in adult patients with a normal airway. Methods: Sixty adult patients (ASA I-III, 18-60 years) scheduled for elective surgery under general anaesthesia were allocated into two equal groups- Group K (King Vision) and Group M (McGrath MAC). Number of attempts, intubation time, optimisation manoeuvres, Cormack-Lehane grade, Intubation Difficulty Scale (IDS) score, serial haemodynamic variables and complications were recorded. Results: First-attempt success was 100% in Group M versus 86.66% in Group K (p
