title: User satisfaction and forces generated during laryngoscopy using disposable Miller blades: a manikin study.
abstract: Increasing awareness of prion-related diseases has led to an increase in the number of disposable laryngoscope blades available. We compared 11 disposable and standard re-usable Miller size 1 blades. In this manikin-based study, we studied user satisfaction for field of view at laryngoscopy, build quality and users' willingness to use the blade in an emergency situation. These were found to be better with metal disposable blades (p</=0.001). Vertical and horizontal forces developed during laryngoscopy were greater with plastic than with metal blades.
