A comparison of the McGrath^®Series 5 videolaryngoscope and Macintosh laryngoscope for double-lumen tracheal tube placement in patients with a good glottic view at direct laryngoscopy

Abstract

SummaryWe compared the 3) s, p < 0.05) and a higher incidence of double-lumen tube malposition (6 (12.5%) vs 0, p < 0.05). However, in 18 non-randomised patients with Cormack and Lehane grade ≥ 2b on initial laryngoscopy using the Macintosh, the glottic view was improved on intubation with the McGrath videolaryngoscope, with a total success rate of double-lumen tube placement of 94.4% and mean (SD) intubation time of 50.0 (18.6) s. We recommend that in patients with a low airway risk index score requiring intubation with a double-lumen tracheal tube, the Macintosh laryngoscope is used as the first device and the McGrath videolaryngoscope is used only if this provides a poor glottic view.

McGrath Series 5 videolaryngoscope vs Airtraq DL videolaryngoscope for double-lumen tube intubation

“…A previous study showed that the McGrath Series 5 increased the incidence of DLT malposition. [12] In the present study, we found there was no significant difference in the incidence of DLT malposition between the 2 groups (6 patients in the Airtraq group and 10 patients in the McGrath group). Actually, DLT malposition was not an issue when using a videolaryngoscope in DLT intubation because fibre-optic bronchoscopy was routinely used for checking the position of the DLT.…”

“…[3,4] Furthermore, videolarynoscopes are recommended in cases of unexpected and expected difficult airway management. [5,6] Recently, many different types of video devices have been reported for use in DLT intubation including the GlideScope, [7–11] McGrath Series 5, [12,13] Airtraq, [14,15] CEL-100, [16,17] Pentax Airway Scope, [18] videolaryngoscopes with MAC blade, [19] video stylet, [20,21] and VivaSight-DL. [22,23] …”

“…[12,13] Therefore, we compared the McGrath Series 5 (Aircraft Medical, Edinburgh, UK) with the Airtraq DL (ProdolMeditec, Viscaya, Spain) for DLT intubation by experienced anesthesiologists. The outcomes will be guided for choosing a videolaryngoscope for DLT intubation in cases of failed intubation with the Macintosh laryngoscope.…”

Use of the Macintosh laryngoscope for double‐lumen tracheal tube placement

“…We read with interest the article by Yao et al. comparing the McGrath ® Series 5 videolaryngoscope (Aircraft Medical Limited, Edinburgh, UK) with the Macintosh laryngoscope for double‐lumen tracheal tube placement. They recommend that in patients with a low airway risk index score requiring intubation with a double‐lumen tracheal tube, the classic Macintosh laryngoscope is used as the initial device and the McGrath videolaryngoscope is used only if the classic Macintosh laryngoscope provides a poor glottic view.…”

Changing double‐lumen tracheal tube curvature

“…We read Yao et al. 's article comparing the McGrath Series 5 videolaryngoscope and Macintosh laryngoscope for double‐lumen tracheal tube (DLT) placement with interest , and would like to invite the authors to reply to several comments.…”
