Evaluation of the Video Intubation Unit in morbid obese patients

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 1 2010
I. BATHORY
Background: Tracheal intubation may be more difficult in morbidly obese (MO) patients than in the non-obese. The aim of this study was to evaluate clinically if the use of the Video Intubation Unit (VIU), a video-optical intubation stylet, could improve the laryngoscopic view compared with the standard Macintosh laryngoscope in this specific population. Methods: We studied 40 MO patients (body mass index >35 kg/m2) scheduled for bariatric surgery. Each patient had a conventional laryngoscopy and a VIU inspection. The laryngoscopic grades (LG) using the Cormack and Lehane scoring system were noted and compared. Thereafter, the patients were randomised to be intubated with one of the two techniques. In one group, the patients were intubated with the help of the VIU and in the control group, tracheal intubation was performed conventionally. The duration of intubation, as well as the minimal SpO2 achieved during the procedure, were measured. Results: Patient characteristics were similar in both groups. Seventeen patients had a direct LG of 2 or 3 (no patient had a grade of 4). Out of these 17 patients, the LG systematically improved with the VIU and always attained grade 1 (P<0.0001). The intubation time was shorter within the VIU group, but did not attain significance. There was no difference in the SpO2 post-intubation. Conclusion: In MO patients, the use of the VIU significantly improves the visualisation of the larynx, thereby improving the intubation conditions. [source]

Comparison of the Cobalt Glidescope® video laryngoscope with conventional laryngoscopy in simulated normal and difficult infant airways,

Summary Aim:, To evaluate the new pediatric Glidescope® (Cobalt GVL® Stat) by assessing the time taken to tracheal intubation under normal and difficult intubation conditions. We hypothesized that the Glidescope® would perform as well as conventional laryngoscopy. Background:, A new pediatric Glidescope® became available in October 2008. It combines a disposable, sterile laryngoscope blade and a reusable video baton. It is narrower and longer than the previous version and is available in a greater range of sizes more appropriate to pediatric use. Methods:, We performed a randomized study of 32 pediatric anesthetists and intensivists to compare the Cobalt GVL® Stat with the Miller laryngoscope under simulated normal and difficult airway conditions in a pediatric manikin. Results:, We found no difference in time taken to tracheal intubation using the Glidescope® or Miller laryngoscope under normal (29.3 vs 26.2 s, P = 0.36) or difficult (45.8 and 44.4 s, P = 0.84) conditions. Subjective evaluation of devices for field of view (excellent: 59% vs 53%) and ease of use (excellent: 69% vs 63%) was similar for the Miller laryngoscope and Glidescope®, respectively. However, only 34% of participants said that they would definitely use the Glidescope® in an emergency compared with 66% who would be willing to use the Miller laryngoscope. Conclusions:, The new Glidescope® performs as well as the Miller laryngoscope under simulated normal and difficult airway conditions. [source]

A comparison between the GlideScope® Video Laryngoscope and direct laryngoscope in paediatric patients with difficult airways , a pilot study

Summary The GlideScope® Video Laryngoscope may improve the view seen at laryngoscopy in adults who have a difficult airway. Manikin studies and case reports suggest it may also be useful in children, although prospective studies are limited in number. We hypothesised that the paediatric GlideScope will result in an improved view seen at laryngoscopy in children with a known difficult airway, compared to direct laryngoscopy. Eighteen children with a history of difficult or failed intubation were prospectively recruited. After inhalational induction, each patient had laryngoscopy performed using a standard blade followed by GlideScope videolaryngoscopy. The GlideScope yielded a significantly improved laryngoscopic view, both with (p = 0.003) and without (p = 0.004) laryngeal pressure. The mean (SD) time taken to achieve the optimal view was 20 (8)s using conventional laryngoscopy and 26 (22)s using the GlideScope® (p = 0.5). The GlideScope® significantly improves the laryngoscopic view obtained in children with a difficult airway. [source]
