evaluation of new Laryngoscope Blade for tracheal intubation truview evo2 a manikin study
European Journal of Anaesthesiology, 2008Co-Authors: Luca Miceli, M Cecconi, G Tripi, M Zauli, G Della RoccaAbstract:Background and objective: Difficult airways present a clinical challenge for anaesthetists. The Truphatek Truview EVO2© (Truphatek International Ltd, Netanya, Israel) is a new Laryngoscope Blade used for endotracheal intubation that could be used where there is difficulty in visualizing the laryngeal inlet. Methods: Twenty anaesthetists (12 trainees and eight consultants) compared the Truphatek Truview EVO2© with a conventional Macintosh size 3 Blade. The Trucorp Airsim Bronchi© (Trucorp Ltd, Belfast, Northern Ireland, UK) manikin was intubated under normal conditions and under simulated difficult conditions such as tongue inflation and neck rigidity. In each scenario, the Cormack-Lehane grade, time needed for successful intubation, perceived difficulty of tracheal intubation and personal preference of Blade were compared. The results were analysed with t-test (time of intubation), Wilcoxon signed-rank sum (Cormack-Lehane grade, ease of manoeuvre, preferred Blade) and analysis of variance with Bonferroni correction (augmentation of difficulties in different scenarios). Results: The Truview EVO2 Blade allowed the best laryngeal view as judged by the Cormack-Lehane grade (P < 0.05) in two separate situations: under simulated tongue inflation and under simulated neck rigidity. However, this Blade did not reduce the intubation time or the ease of tracheal tube placement with respect to conventional Macintosh Blade. Conclusion: Compared with the classical Macintosh Blade, the Truview EVO2 Blade allowed a better view of the larynx, but did not facilitate endotracheal intubation in any of the difficult scenarios created with the adjustable manikin and in most scenarios in fact prolonged the intubation time.

a macintosh Laryngoscope Blade for videolaryngoscopy reduces stylet use in patients with normal airways
Anesthesia & Analgesia, 2009Co-Authors: Adrien Van Zundert, R Maassen, R Willems, Michel Timmerman, Marc Siemonsma, Marc P Buise, Marco WiepkingAbstract:BACKGROUND: Although most tracheal intubations with direct laryngoscopy are not performed with a styletted endotracheal tube, it is recommended that a stylet can be used with indirect videolaryngoscopy. Recently, there were several reports of complications associated with styletted endotracheal tubes and videolaryngoscopy. In this study, we compared three videoLaryngoscopes (VLSs) in patients undergoing tracheal intubation for elective surgery: the GlideScope® Ranger™ (GlideScope, Bothell, WA), the V-MAC™ Storz® Berci DCI+ (Karl Storz, Tuttlingen, Germany), and the McGrath® (McGrath series 5, Aircraft medical, Edinburgh, UK) and tested whether it is feasible to intubate the trachea of patients with indirect videolaryngoscopy without using a stylet. METHODS: Four hundred fifty consecutive adults (ASA PS I-II) undergoing tracheal intubation for elective surgery were randomly allocated for airway management with one of the three devices. Anesthesia induction for tracheal intubation consisted of fentanyl-propofol-rocuronium. An independent anesthesiologist used the Cormack-Lehane grading system to score an initial direct laryngoscopic view using a classic metal Macintosh Blade. After subsequent positive-pressure ventilation using a face mask and an oxygen-sevoflurane mixture for 1 min, the trachea was intubated using one of the three VLSs. During intubation, the following data were collected: intubation time, number of intubation attempts, use of extra tools to facilitate intubation, and overall satisfaction score of the intubation conditions. RESULTS: The trachea of every patient was intubated using the VLSs, and none of the patients required conversion to the classic Macintosh Laryngoscope. All three VLSs offered equal or better view of the glottis as assessed by the mean Cormack-Lehane grade, compared with the traditional Macintosh laryngoscopy, including a larger viewing angle of the glottic entrance. The average intubation time was 34 ± 20 s for the GlideScope, 18 ± 12 s for the V-MAC Storz, and 38 ± 23 s for the McGrath VLS. Intubation with the Storz was faster (P < 0.05) than the other two VLS tested and necessitated fewer additional tools (P < 0.01), resulting in a higher first-pass successful intubation rate. A stylet had to be used in 7% of the patients in the Storz group versus about 50% of the patients when the other two VLS were used. CONCLUSIONS: The trachea of a large proportion of patients with normal airways can be intubated successfully with certain VLS Blades without using a stylet, although the three studied VLSs clearly differ in outcome. The Storz VLS displaces soft tissues in the fashion of a classic Macintosh scope, affording room for tracheal tube insertion and limiting the need for stylet use compared with the other two scopes. Although VLSs offer several advantages, including better visualization of the glottic entrance and intubation conditions, a good laryngeal view does not guarantee easy or successful tracheal tube insertion. We recommend that the geometry of VLSs, including Blade design, should be studied in more detail. Copyright

a comparison of three videoLaryngoscopes the macintosh Laryngoscope Blade reduces but does not replace routine stylet use for intubation in morbidly obese patients
Anesthesia & Analgesia, 2009Co-Authors: R Maassen, Boukje Hermans, Marco A E Marcus, Adrien Van ZundertAbstract:BACKGROUND:: Many manufacturers are producing videoLaryngoscopes (VLSs) with differing specifications, user interfaces, and geometry. It is clinically relevant to know the relative performance of the Blades. Visualization of the glottis and intubation are often problematic in (extremely) obese patients, and the new video technology may offer better functionality and performance. Although many tracheal intubations with direct laryngoscopy are performed with an unstyletted endotracheal tube, it is recommended to use a stylet for intubation using videolaryngoscopy. In this study, we compared 3 VLSs in morbidly obese patients undergoing intubation for elective surgery and tested whether it is feasible to intubate the tracheas of morbidly obese patients without using a stylet. METHODS:: One hundred fifty consecutive adult morbidly obese patients (body mass index >35 kg/m 2) were randomly selected to receive one of 3 VLSs: GlideScope®, Storz® V-Mac™, and McGrath®. Direct laryngoscopy scored the best possible view of the glottis; subsequently, the respective VLS was used, and the patient's trachea was intubated. Common preprocedural (e.g., Mallampati grade) and intraprocedural (Cormack-Lehane grade) metrics of intubation difficulty were measured, as well as the dependent variables of intubation time, number of attempts, and subjective difficulty. RESULTS:: All 3 VLSs tested offered an equal or better view of the glottis compared with traditional direct laryngoscopy. The number of attempts necessary to intubate the trachea differed significantly among VLSs (average 2.6 ± 1.0 attempts for the GlideScope, 1.4 ± 0.7 for the Storz, and 2.9 ± 0.9 for the McGrath VLS). The average intubation times were 33 ± 18 s for the GlideScope, 17 ± 9 s for the Storz, and 41 ± 25 s for the McGrath VLS. CONCLUSIONS:: In this study, the VLS with the Macintosh Blade (Storz VLS) had a better overall satisfaction score, intubation time, number of intubation attempts, and necessity of extra adjuncts, compared with the 2 other tested devices.
