“…[1][2][3] Video laryngoscopy has been demonstrated to improve first-pass and ultimate success and decrease iatrogenic airway trauma during endotracheal intubation in adults. [4][5][6] In addition to clinical benefit, the ability to review videos captured during laryngoscopy provides a unique opportunity to assess metrics related to procedural performance and quality of care. The C-MAC video laryngoscope blades (Karl Storz, Tuttlingen, Germany) are structurally similar to those of conventional laryngoscopes, but allow continuous recording of intubations.…”

Objectives: Using recordings of endotracheal intubation attempts obtained with a video-enabled laryngoscope with Miller and Macintosh blades, the authors sought to evaluate the association between laryngoscopic approach (right-sided vs. midline) and intubation success, as well as adverse event rates in the pediatric emergency department (ED).Methods: This was a retrospective cohort study of children younger than 21 years who underwent endotracheal intubation with a C-MAC video laryngoscope in a tertiary care ED between August 2009 and May 2013. The primary outcome was successful endotracheal intubation on the first attempt. The secondary outcomes included time to intubation, video-recorded adverse events (oropharyngeal mucosal injury and aspiration), and physiologic adverse events. Multivariate regression models were used to determine the relationship between laryngoscope blade position and outcome measures adjusted for patient and provider factors.Results: The cohort consisted of complete video recordings for 105 of 143 (73%) patient encounters with intubations. The first-pass success rate did not significantly differ based on laryngoscopic approach (adjusted odds ratio [aOR] = 0.76, 95% confidence interval [CI] = 0.29 to 2.0). Among patients successfully intubated on the first attempt, the median time to intubation was longer for the right-sided approach compared to the midline approach (42 seconds vs. 31.5 seconds; p < 0.05). The odds of mucosal injury and aspiration were higher among patients intubated using a right-sided approach compared to a midline approach (aOR = 4.1, 95% CI = 1.2 to 14.5; aOR = 7.7, 95% CI = 1.5 to 39.5, respectively). Rates of physiologic adverse events did not differ based on approach.Conclusions: First-pass success rate did not differ based upon laryngoscopic approach type; however, a right-sided approach was associated with a longer time to intubation, as well as higher rates of mucosal injury and aspiration among patients undergoing video-enabled intubation in a pediatric ED.

“…Difficult intubation and failed tracheal intubation are among the major causes of morbidity and mortality associated with anaesthesia (3,4). 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).…”

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.

“…If the direct glottic view cannot be obtained, indirect laryngoscopes are found to be useful to the anesthesiologist to view the cords and increase the success of intubation [11] Various laryngoscopes (as C mac D-blade and Airtraq) were invented recently, which differ in shape and imaging technologies. Fiberoptic bronchoscope is the gold stander to deal with difficult intubation [4].…”

Background: Several complications may be correlated with difficult airway up to death. Fiberoptic bronchoscope is the gold stander to deal with difficult intubation. Airtraq laryngoscope and C-MAC® video laryngoscope are new devices that are used successfully for tracheal intubation. We compared using C-MAC D-blade video laryngoscope, Airtraq laryngoscope, and Fiberoptic bronchoscope for intubation of patient likely to have difficult intubation.

Comparison of video laryngoscopes with direct laryngoscopy for tracheal intubation

Abstract: Video laryngoscopes are a good alternative to direct laryngoscopy during tracheal intubation. The advantage seems to be more prominent when difficult intubation is encountered.
