About

In the presented study, our aim was to compare intubation conditions regarding the modified Cormack & Lehane score (CL) between the D-Blade® in indirect laryngoscopy or Macintosh blade in direct and indirect laryngoscopy with C-MAC PM® in a simulated setting of a difficult airway in human subjects.

Full description

Patients with unexpected difficult airway requiring endotracheal intubation (ETI) remain extremely challenging for emergency physicians and intubation failure with subsequent hypoxic complications still represents the majority of cases in a recent closed claims analysis.

An incidence of major complications in airway management of 1 in 5,500 was estimated in the Fourth National Audit Project in the UK.

Therefore, our aim was to compare intubation conditions regarding the modified Cormack & Lehane score (CL) between the D-Blade® in indirect laryngoscopy or Macintosh blade in direct and indirect laryngoscopy with C-MAC PM® in a simulated setting of a difficult airway in human subjects.
