Resumen
[Abstract] Introduction: There is uncertainty about the optimal videolaryngoscope for awake tracheal intubation in patients with anticipated difficult airway. The use of channelled and unchannelled videolaryngoscopy has been reported, but there is a lack of evidence on which is the best option.
Methods: We conducted a randomised clinical trial to compare the efficacy of the C-MAC D-Blade® vs. Airtraq® in adult patients (aged ≥ 18 y) scheduled for elective or emergency surgery under general anaesthesia with anticipated difficult airway who required awake tracheal intubation under local anaesthesia and conscious sedation. The primary endpoint was the first-attempt tracheal intubation success rate. Secondary outcomes included the overall success rate; number of tracheal intubation attempts; Cormack and Lehane glottic view; level of difficulty (visual analogue score); patient discomfort (visual analogue score); and incidence of complications.
Results: Ninety patients (70/90 male (78%); mean (SD) age 65 (12) y) with anticipated difficult airways were randomly allocated to C-MAC D-Blade or Airtraq videolaryngoscopy. First-attempt successful tracheal intubation rate was higher in patients allocated to the C-MAC D-Blade group compared with those allocated to the Airtraq group (38/45 (84%) vs. 28/45 (62%), respectively; p = 0.006). The proportion of patients' tracheas that were intubated at the second and third attempt was 4/45 (9%) and 3/45 (7%) in those allocated to the C-MAC D-Blade group compared with 14/45 (31%) and 1/45 (2%) in those allocated to the Airtraq group (p = 0.006). There was no significant difference in overall tracheal intubation success rate (C-MAC D-Blade group 45/45 (100%) vs. Airtraq group 43/45 (96%), p = 0.494).
Discussion: In patients with anticipated difficult airway, first-attempt awake tracheal intubation success rate was higher with the C-MAC D-Blade compared with Airtraq laryngoscopy. No difference was found between the two videolaryngoscopes in overall tracheal intubation success rate.
