“…A variety of work has been done to study the laryngoscopic view, ease of intubation, hemodynamic changes during laryngoscopy, and intubation and associated complications in patients with cervical collar in situ. 12 The Airtraq video-laryngoscope has been designed to facilitate intubation in normal and anticipated difficult cases. It does so, because of its blade with exaggerated curvature and an internal arrangement of optical components which facilitates a better view of the glottis and reduces the number of airway optimization maneuvers required.…”

“…Modified intubation difficulty score (IDS) described by Adnet et al, using the seven parameters (number of operators, number of attempts, number of additional techniques, Cormack-Lehane view, lifting force, laryngeal pressure, and vocal cord position) for intubation with Airtraq and McCoy laryngoscope was noted (►Table 1). 12 Difficulty in insertion of laryngoscope was graded by the intubating anesthesiologist as per Likert's scale i.e., 2 (very difficult to insert) to +2 (very easy to insert). Airway-related complications in the form of injury to lips, teeth, mucosal injury, laryngospasm, bronchospasm, postoperative stridor, and sore throat were also noted.…”

Background Immobilization of cervical spine is of utmost importance in patients with cervical injury, making intubation a difficult task due to the application of cervical collar. This study was done to assess which laryngoscope (Airtraq or McCoy) is better for intubation and prevents the deleterious effects of hypoxia by comparing the intubation time. Methods A prospective interventional randomized study was undertaken in 60 adult patients of American Society of Anesthesiologists (ASA) grade I and II, aged between 20 and 50 years, scheduled for various surgical procedures requiring tracheal intubation for anesthesia. Patients were randomly allocated to undergo intubation with either the Airtraq (Group A; n = 30) laryngoscope or McCoy (Group B; n = 30). Patients were intubated following the standard anesthetic protocol, and the differences in duration of intubation, changes in the hemodynamic parameters in response to intubation, modified intubation difficulty score, and airway complications between the Airtraq and the McCoy laryngoscope were compared. Results Overall intubation success rates were 100% with both devices and a similar number of intubation attempts were required. Though the mean time required for successful intubation was less with the Airtraq (25.2 ± 5.11 seconds) than the McCoy laryngoscope (27.3 ± 4.47 seconds); it was statistically insignificant (p = 0.14). Intubation difficulty score and ease of insertion were significantly less in Airtraq laryngoscope when compared with McCoy laryngoscope. Increase in the heart rate and mean arterial pressure was significantly more just after intubation with McCoy in comparison with Airtraq laryngoscope. However, the frequencies of airway complications were similar. Conclusion Intubation time despite being lesser with the Airtraq than the McCoy laryngoscope was statistically insignificant, and overall success rates between the two devices were similar.

“…The factors which determine difficulty of intubation are number of attempts, number of operators, alternative technique used, glottis exposure, application of lifting force external pressure, and the vocal cord position. The intubation difficulty score[ 1 17 18 ] consist of these 7 parameters. Score of 0, easy intubation, <5, slight difficulty, and >5, moderate to severe difficulty.…”

“…The ease of insertion of the scope was graded using 5-point Likert scale [ Table 1 ]. [ 17 ] The difficulty of intubation was assessed using modified intubation difficulty score (IDS) [ Table 1 ][ 1 18 20 ] using 7 parameters. Any complications such as airway trauma, esophageal intubation, desaturation, bronchospasm, and injury to teeth were also noted.…”

Background:Glottic visualization can be difficult with cervical immobilization in patients with cervical spine injury. Indirect laryngoscopes may provide better glottic visualization in these groups of patients. Hence, we compared King Vision videolaryngoscope, C-MAC videolaryngoscope for endotracheal intubation in patients with proven/suspected cervical spine injury.Methods:After standard induction of anesthesia, 135 patients were randomized into three groups: group C (conventional C-MAC videolaryngoscope), group K (King Vision videolaryngoscope), and group D (D blade C-MAC videolaryngoscope). Cervical immobilization was maintained with Manual in line stabilization with anterior part of cervical collar removed. First pass intubation success, time for intubation, and glottic visualization (Cormack – Lehane grade and percentage of glottic opening) were noted. Intubation difficulty score (IDS) was used for grading difficulty of intubation. Five-point Likert scale was used for ease of insertion of laryngoscope.Results:First attempt success rate were 100% (45/45), 93.3% (42/45), and 95.6% (43/45) in patients using conventional C-MAC, King Vision, and D blade C-MAC videolaryngoscopes, respectively. Time for intubation in seconds was significantly faster with conventional C-MAC videolaryngoscope (23.3 ± 4.7) compared to D blade C-MAC videolaryngoscope (26.7 ± 7.1), whereas conventional C-MAC and King Vision were comparable (24.9 ± 7.2). Good grade glottic visualization was obtained with all the three videolaryngoscopes.Conclusion:All the videolaryngoscopes provided good glottic visualization and first attempt success rate. Conventional C-MAC insertion was significantly easier. We conclude that all the three videolaryngoscopes can be used effectively in patients with cervical spine injury.
