“…Indirect laryngoscopes improve the view and increase the success of intubation in cases when direct glottic view is difficult to obtain (5). In recent years, video laryngoscopy has gained an increasingly important role in the management of difficult and emergent laryngoscopy (6). This method allows for better visualization of anatomical structures, and it can be used as an educational tool (7).…”

Objective: Recently, to further enhance the potential in the management of difficult airways, the highly angulated D-Blade was added to the C-MAC system. The purpose of this study was to investigate the laryngoscopic view and intubation parameters using the new C-MAC D-Blade in comparison to the conventional C-MAC video laryngoscope and Macintosh direct laryngoscope in simulated easy and difficult airways. Methods:We recruited 26 experienced anaesthesia providers into a randomized trial. Each performed tracheal intubation of a Laerdal SimMan ® manikin with each laryngoscope in the following laryngoscopy scenarios: (1) normal airway, (2) cervical spine immobilization, and (3) tongue edema. The intubation times, success rates, number of intubation attempts, laryngoscopic views, and severity of dental compression were recorded. Results:In all scenarios, video laryngoscopes provided better laryngeal exposure than the ML and appeared to produce less dental pressure. In the cervical spine immobilization scenario, D-Blade caused less dental pressure and showed better Cormack-Lehane (CL) classes than the other devices (p<0.001). There were no differences between video laryngoscopes in success of tracheal intubation (p>0.05). The CMAC provided the most rapid intubation. The rate of failure was 19% with ML. In the tongue edema scenario, the CMAC provided the most rapid and successful intubation (p<0.001). There were no differences between video laryngoscopes in laryngoscopic views according to CL classification and dental pressure (p>0.05). The rate of failure was 46% with the ML and 7% with the D-Blade. Conclusion:The CMAC D-Blade caused less dental pressure than the conventional C-MAC and ML in the cervical immobilization scenario. The conventional CMAC performed better than the D-Blade and ML in the tongue edema scenario. These two video laryngoscopes may complement each other in various difficult airway situations.

“…The paraglossal straight blade and the videolaryngoscope have been shown in both manikin and human studies to improve the view of the larynx when compared with the Macintosh blade and to be useful in anticipated difficult airway management [3,[8][9][10]. However, no study has been performed comparing these two devices.…”

“…Straight blades are normally designed with a slight anterior curve at the tip, which is used to elevate the epiglottis directly. Video-assisted devices have become popular, allowing a better view of the larynx, and may be potentially useful in difficult tracheal intubations [9][10][11][12][13].…”

SummaryStudies show that both straight blade laryngoscopy and videolaryngoscopy can improve the view of the larynx when compared with the Macintosh blade laryngoscopy. However, no study has compared these two devices. A total of 80 patients with Mallampati grade ≥ 3 were randomly assigned to either have orotracheal intubation with the McGrath® videolaryngoscope or the Henderson straight blade. The primary outcome was laryngoscopic view. Time to intubation, number of attempts, ease of intubation and complications were also recorded. Thirty‐nine out of 40 patients had grade‐1 views in the McGrath group, compared with 29 out of 40 cases in the Henderson group (p = 0.003). There were no statistically significant differences in the secondary outcomes. Two patients suffered from minor oropharyngeal injuries in the Henderson group. Apart from offering significantly more grade‐1 laryngoscopic views, the McGrath videolaryngoscope did not improve other clinical outcomes compared with the straight blade, when used in patients with poor Mallampati scores.
