Tracheal intubation using the ILMA, C‐Trach ^TM or McCoy laryngoscope in patients with simulated cervical spine injury

Abstract

A study of 90 patients was undertaken to compare intubation success rates of using either ILMA, C-Trach or McCoy laryngoscope in patients with simulated cervical spine injury. Insertion and intubation success rates, time taken to achieve intubation, airway complications and haemodynamic parameters were recorded. Insertion of ILMA and C-Trach was successful at the first attempt in all patients. Intubation success rates were higher in the C-Trach (100%) and McCoy (100%) groups than in the ILMA (87%) group. Total intubation time was significantly longer in the ILMA (63 s, SD 36.5) group than in the C-Trach (41 s, SD 15.8) and McCoy (30 s, SD 7.4) groups (p < 0.05, p < 0.05, respectively). There were no significant differences in haemodynamic parameters among the groups at any time.
