“…[ 34 ] However, difficult DLT endobronchial intubation using videolaryngoscopes was only documented in case series and a retrospective study. [ 17 , 20 , 21 ] For the present prospective randomized controlled study, we applied in-line stabilization as a simulated difficult airway. Manual in-line stabilization was used to simulate 1 type of difficult direct laryngoscope scenario, because it increases rates of failed intubation, secondary to adverse impact on the laryngeal view during direct laryngoscopy.…”

Background:Double lumen endobronchial tube (DLT) intubation is commonly used for one-lung ventilation in thoracic surgery. However, because of its large size and shape, it is difficult to perform intubation compared with a single lumen tube. The aim of this randomized controlled trial was to determine whether the McGrath videolaryngoscope has any advantage over the direct Macintosh laryngoscope for DLT intubation in patients with a simulated difficult airway.Methods:Forty-four patients (19–60 years of age); scheduled to undergo general anesthesia with one-lung ventilation were assigned to 1 of 2 groups: DLT intubation with the McGrath videolaryngoscope (ML group [n = 22]); or conventional Macintosh laryngoscope (DL group [n = 22]). After manual in-line stabilization was applied as a way of simulating a difficult airway, the time required for intubation and the quality of glottic view were evaluated.Results:The time to successful intubation was not different between the 2 groups (ML group, 45 s [interquartile range, 38–52 s] versus DL group, 54 s [45–59 s]; P = .089). The McGrath videolaryngoscope, however, provided a significantly better glottic view. Modified Cormack and Lehane grade was better (P < .001), and the percentage of glottis opening score was higher in the ML group (P < .001). Overall intubation difficulty scale score was lower in the ML group (1 [0–2]) versus the DL group (3 [2–4]) (P < .001).Conclusion:The McGrath videolaryngoscope improved glottic view and resulted in lower overall intubation difficulty scale score in patients with in-line stabilization.

“…Several studies and case series have reported improved laryngeal views and greater intubation success rates in patients with predicted and known difficult airways using the McGrath videolaryngoscope [6][7][8][9][10]. There are, however, no randomised controlled clinical trials comparing the McGrath videolaryngoscope with the Macintosh laryngoscope in patients managed with manual in-line stabilisation.…”

The McGrath^® Series 5 videolaryngoscope vs the Macintosh laryngoscope: a randomised, controlled trial in patients with a simulated difficult airway

Summary We compared the McGrath® Series 5 videolaryngoscope with the Macintosh laryngoscope in a simulated difficult airway, using manual in‐line stabilisation in 88 anaesthestised patients of ASA physical status 1‐2. The primary outcome was laryngoscopic view. Secondary outcomes included rates of successful tracheal intubation and complications. A Cormack and Lehane grade‐1 or ‐2 view was found in all patients when using the McGrath compared with 45 (51%, p < 0.0001) using the Macintosh laryngoscopes. The mean (SD) percentage of glottic opening was 82 (23)% using the McGrath compared with 13 (23)% using the Macintosh (p < 0.0001). In 66 out of 88 patients (75%), the McGrath improved the glottic view by one to three grades compared with the Macintosh (p < 0.001). Intubation of the trachea was successful in all patients using the McGrath, while the Macintosh was successful in 26 (59%, p < 0.001). There was no significant difference in the complication rates between the devices.

В последующем воспалительный процесс приводит к тому, что Казанский медицинский журнал, 2016 г., том 97, №6 открыть рот невозможно даже после введения миорелаксантов [21,34].…”

Main causes of difficult intubation

Difficult or unsuccessful intubation occur in anesthesiologist’s practice infrequently but such situations may have direct threat to a patient’s life. Often mortality associated with anesthesia is caused precisely by difficulties of intubation. The article deals with analyses of the causes of possible difficult intubation in the practice of anesthesiologist and intensivist in planned and emergency situations. Mallampati test, evaluation of thyromantal distance and mobility of atlanto-occipital joint can be used to predict difficult intubation. According to most recent publications, the most effective way to predict it is the «LEMON» score. Ample opportunities for overcoming difficulties of tracheal intubation are created by recently introduced techniques of videolaryngoscopy - different types of video laryngoscope-modifications of Macintosh blades. Their features compared to classic intubation with the use of Macintosh and Magil blades are excellent view and complete visual control of structures of the larynx.
