Video laryngoscopy — device types, advantages over direct laryngoscopy, and the evidence

Final SAQ — the principle of the indirect tip-camera view; the channelled (Airtraq, Pentax AWS) versus the non-channelled/hyperangulated (GlideScope, McGrath portable, C-MAC dual-role) families; the advantages (fewer failed intubations, better glottic view, no axis alignment, shared view for teaching and supervision, recording); the disadvantages (fogging and secretions, 'can see but cannot tube', screen and power dependence, cost, learning curve); the midline technique with a hockey-stick stylet; and the evidence subtlety that an improved view does not always translate into faster or easier intubation, particularly in the routine case and in infants.
