“…For the GlideScope®, TTI was longer in the J shape than the 90° stylet [10]. However, another study demonstrated faster intubation with the J shape for GlideScope®, as well as for the C-MAC [9,21]. In our study, the J-shape showed comparable intubation quality with the 60° stylet for intubation with the McGrath MAC®.…”

Background: Adequate shapes for videolaryngoscopes are important for safer, faster, and successful intubation. The aim of this study was to compare two different shapes of stylets, the 60º and J-shape stylets, for intubation with the McGrath MAC®. Methods: In this multicenter, prospective, randomized controlled study, patients undergoing elective surgery under general anesthesia were randomly assigned into the 60º group or the J group. After anesthetic induction, subjects in both groups were intubated with an endotracheal tube bent into a specific shape according to the group allocation. Time to intubation, difficulty of intubation, glottic view grade, use of external manipulation, and number of intubation attempts were recorded. Results: One hundred and eight patients in the J group and 110 patients in the 60º group were enrolled. Time to intubation in the J group [23.1 (20.6-28.0)] was not different from the 60º group [24.8 (20.5-28.3), P = 0.623). There were no differences in difficulty of intubation, glottic view grade, use of external manipulation, and number of intubation attempts between the two groups. Conclusions: Adding extra curvature to the tube to resemble the shape of the blade did not improve the intubation conditions of the McGrath MAC®.

“…The results suggested that different stylet angulations and shapes might be used according to the type of video laryngoscope because of differences in the design of each videolaryngoscope. 7 , 11 , 21 , 22 When using the GlideScope® video laryngoscope, a 90° angled stylet facilitated faster and easier intubation than did a 60° angled stylet. 11 , 23 When using the C-MAC D-Blade® video laryngoscope (Karl Storz GmbH, Tuttlingen, Germany), a stylet with a blade shape or hockey stick shape allowed better performance in intubation.…”

“… 11 , 23 When using the C-MAC D-Blade® video laryngoscope (Karl Storz GmbH, Tuttlingen, Germany), a stylet with a blade shape or hockey stick shape allowed better performance in intubation. 22 To the best of our knowledge, however, few studies have involved the MVL. One study showed that the TTI was shorter with the 60° than 90° stylet, which was a result opposite that of the GlideScope®.…”

Objective This study was performed to compare two different shapes of stylets, 60° and J-shaped stylets, for intubation using the McGrath MAC® video laryngoscope (MVL). Methods Two hundred twenty-two patients undergoing surgery under general anesthesia were randomly allocated to Group J (n = 111) or Group 60° (n = 111) and intubated using the MVL with the stylet bent into the allocated shape. The time to intubation (TTI) and other intubating profiles were compared between the groups. Multivariate regression analysis was used to determine the relationship between factors related to difficult intubation and TTI. Results The TTI was not different between the two groups. There were also no differences in the intubating profiles between the two groups. In both groups, the TTI was longer with a modified Mallampati score (mMS) of ≥3 and percentage of glottic opening (POGO) score of <50. In Group J, the TTI was longer with a body mass index (BMI) of ≥30 kg/m2. Conclusion The TTI during tracheal intubation with the MVL was not different between the two groups. The TTI was longer with an mMS of ≥3 and POGO score of <50. In Group J, the TTI was longer with a BMI of ≥30 kg/m2.
