Preliminary evaluation of a novel videolaryngoscope, the McGrath series 5, in the management of difficult and challenging endotracheal intubation

A randomised controlled trial comparing the McGrath® videolaryngoscope with the straight blade laryngoscope when used in adult patients with potential difficult airways*

“…There were eight other occasions when the view was a grade 1, yet there was difficulty in manipulating the tracheal tube through the laryngeal inlet, as evidenced by needing at least two attempts to pass the tube through the cords. In another parallel study using the McGrath videolaryngoscope in patients with challenging airways, even with a good view, 22% of cases were associated with difficulty during intubation [23].…”

Clinical application of a novel video camera laryngoscope: a case series venturing beyond the normal airway

“…3), obtaining a clear view of anteriorly displaced vocal cords is possible. However, the most common complaint is obtaining a grade 1 view, but being unable to pass the ETT into the trachea [2][3][4]. This is likely due to the curvature and length of the McGRATH laryngoscope blade.…”

Direct and Indirect Laryngoscopy: Equipment and TechniquesDiscussion

“…[70][71][72] One recent study demonstrated that use of a GlideScope by less experienced operators (Pulmonary and Critical Care Medicine fellows) resulted in better first-attempt intubation success rates with fewer complications (compared with a traditional straight or curved blade) when performed for urgent endotracheal intubations in the critically ill. 73 However, another recent trial of 623 consecutive trauma subjects requiring emergent airway management reported no differences in first-pass success and longer intubation times with use of the GlideScope. 74 In addition, one subgroup of severe head injury trauma subjects in the video laryngoscope cohort also experienced a greater incidence of hypoxia of 80% or less (50% vs 24%).…”
