AbstractThe fibreoptic assisted laryngoscope is a new airway device. We compared the fibreoptic assisted laryngoscope with the Bullard laryngoscope, Macintosh laryngoscope and fibreoptic bronchoscope in a manikin with a simulated Cormack and Lehane Grade 4 laryngoscopic view. Eighteen anaesthetists intubated the manikin's trachea using these devices and the success rate of intubation was measured. They were then asked to rate the subjective difficulty of intubation. The success rate (95% confidence interval) was 100% (94.6-100) with the fibreoptic assisted laryngoscope, 88.9% (80.5-97.3) using the Bullard laryngoscope, 37.0% (24.1-49.9) with the Macintosh laryngoscope, and 22.2% (11.1-33.3) using the fibreoptic bronchoscope. Tracheal intubation using the fibreoptic assisted laryngoscope or Bullard laryngoscope is easier than that using the Macintosh laryngoscope or fibreoptic bronchoscope by subjective difficulty score. All of the intubations were successful with the fibreoptic assisted laryngoscope without practice. These results suggest that fibreoptic assisted laryngoscope may be a useful tool for paediatric difficult intubation.
