Mendonca C, et al. - ‘Sniffing’ and neutral positions were compared using a channelled (KingVision) and a non-channelled (C-MAC D-blade) videolaryngoscope in adult patients, in terms of ease of tracheal intubation, laryngoscopy time, intubation time, laryngoscopic view and success rate of tracheal intubation. Four groups of patients (KingVision ‘sniffing’, KingVision neutral, C-MAC ‘sniffing’ and C-MAC neutral) were examined. No significant difference was noted in the ease of intubation between the ‘sniffing’ and the neutral position when using the KingVision and the C-MAC videolaryngoscopes. Moreover, laryngoscopy time, intubation time and success rate did not significantly differ between the groups. Overall, either of the two positions could be used with these types of videolaryngoscopes, if deemed advantageous for the patient.
