“…Numerous studies have shown that the use of a videolaryngoscope diminishes the necessity of these additional maneuvers, which may result in shorter NTI times as compared to the use of a direct laryngoscope. Tseung et al [28]. reported that use of the GlideScope or Pentax AWS leads to reduced application of BURP, and Hazarika et al [29].…”

Background: Immobilization with cervical spine worsens endotracheal intubation condition. Though various intubation devices have been demonstrated to perform well in oral endotracheal intubation, limited information is available concerning nasotracheal intubation (NTI) in patients with cervical spine immobilization. The present study compared the performance of the C-MAC D-Blade videolaryngoscope with the McCoy laryngoscope for NTI in patients with simulated cervical spine injuries. Methods: This was a prospective, randomized, controlled, study done in a tertiary hospital. Ninety-five patients requiring NTI were included in data analysis: McCoy group (group M, n = 47) or C-MAC D-Blade videolaryngoscope group (group C, n = 48). A Philadelphia neck collar was applied before anesthetic induction to immobilize the cervical spine. Single experienced anesthesiologist performed NTI. The primary outcome was duration of intubation divided by three steps: nose to oropharynx; oropharynx into glottic inlet; and glottic inlet to trachea. Secondary outcomes included glottic view as percentage of glottis opening (POGO) score and Cormack-Lehance (CL) grade, modified nasal intubation-difficulty scale (NIDS) rating, hemodynamic changes before and after intubation, and complications.Results: Total intubation duration was significantly shorter in group C (39.5 ± 11.4 s) compared to group M (48.1 ± 13.9 s). Group C required significantly less time for glottic visualization and endotracheal tube placement in the trachea. More patients in group C had CL grade I and higher POGO scores (P < 0.001, for both measures). No difficulty in NTI (modified NIDS = 0) was more in group C than group M. Hemodynamic changes and incidence of complications were comparable between groups.(Continued on next page)

“…It is much bigger than the blade of traditional DL or MVL. 24 The bulky blade of PVL can make it difficult to insert a PVL into the mouth, which might increase the TTI. In a previous study comparing MVL and PVL during orotracheal intubation, although PVL provided superior glottic view over MVL, the TTI and ease of intubation were similar between the two devices.…”

Background The objective of this study was to determine the clinical usefulness of videolaryngoscopes (VLs) by comparing the time to intubation (TTI) and the ease of intubation of McGrath MAC VL (MVL), Pentax Airway Scope VL (PVL), and Macintosh direct laryngoscope (DL) during nasotracheal intubation using manual in-line stabilization to simulate difficult airways. Methods One hundred and twenty patients were randomly assigned to the MVL group (n = 40), the PVL group (n = 40), and the DL group (n = 40). Nasotracheal intubation was performed using MVL, PVL, or DL, according to group assignments. The primary outcome was TTI and secondary outcomes were glottic view, ease of intubation, and bleeding. ResultsThe TTI was significantly shorter in the MVL group than in the DL group (45 sec vs 57 sec; difference in means: -12; 95% confidence interval [CI], -21 to -3; P = 0.01). The percentage of glottic opening and Cormack Lehane grade were significantly superior in the MVL and the PVL groups compared with the DL group (both P \ 0.001). The intubation difficulty scale and numeric rating scale regarding ease of intubation were also significantly lower in the MVL and PVL groups than in the DL group (all P\0.007). The incidence of bleeding was significantly lower in the MVL group than in the DL group (3 vs 15, relative risk 0.2; 95% CI, 0.06 to 0.64; P = 0.001). Conclusion This study showed that both MVL and PVL provided better visualization of the glottis and easier intubation, with less additional manipulation than DL during nasotracheal intubation in simulated difficult airways. Additionally, use of the MVL significantly shortened the TTI compared with the DL. Trial registration www.clinicaltrials.gov (NCT02647606); registered 6 January, 2016.

“…We speculate that our main finding -higher variability in driving pressures and tidal volumes with pressure-compared with volume-controlled ventilation, should be independent of the airway device used. Perhaps pressure control ventilation may be more effective at achieving sufficiently high tidal volumes in case of a substantial air-leak, although newer supraglottic airways devices may have fewer issues with air leaks [2].…”

“…Obviously, a size-4 GlideScope blade would not be suitable for the paediatric patients included in this study. The design of the blade can affect the performance of videolaryngoscopy for nasotracheal intubation [2], in particular, acute distal angulation and the large size of the GlideScope blade, which can complicate use of the straight Magill forceps, in comparison with the Macintosh blade of the C-MAC videolaryngoscope; Boedeker curved forceps are recommended instead when an angulated-typed videolaryngoscope is used for nasotracheal intubation [3]. In addition, could the authors state which type of GlideScope videolaryngoscope was used in this study -Original, Cobalt, Ranger or Titanium -as different GlideScope videolaryngoscopes can have an effect [4]?…”

A comparison of the video laryngoscopes with Macintosh laryngoscope for nasotracheal intubation

Abstract: As compared with the Macintosh laryngoscope, the GlideScope video laryngoscope facilitated nasotracheal intubations with shortened intubation time and reduced intubation difficulty in patients undergoing oromaxillofacial surgery.
