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(TM) 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(TM) 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.
