Can the ETView VivaSight SL Rival Conventional Intubation Using the Macintosh Laryngoscope During Adult Resuscitation by Novice Physicians?: A Randomized Crossover Manikin Study.

ABSTRACT: The aim of this study was to assess the performance of the ETView VivaSight SL (ETView) single-lumen airway tube with an integrated high-resolution imaging camera in a manikin-simulated cardiopulmonary resuscitation scenario with and without chest compression. This was a randomized crossover manikin trial. Following a brief training session, 107 volunteer novice physicians who were inexperienced with airway management attempted to intubate a manikin using a Macintosh laryngoscope (MAC) and an ETView, with and without chest compressions. The participants were instructed to make 3 attempts in each scenario. In this trial, we compared intubation time, intubation success rates, and glottic visibility using a Cormack & Lehane Grade. Dental compression and ease of use of each device were also assessed. Median intubation times for the ETView and MAC without chest compressions were 17 (IQR, 15-19) s and 27 (IQR, 25-33) s, respectively (P?

Project description:The aim of the present study was to evaluate whether the TruView video laryngoscope (TruView) facilitates pediatric endotracheal intubation (ETI) more quickly and safely than conventional Macintosh laryngoscope (MAC) in three manikin-based airway scenarios. This was a randomized crossover manikin study including 120 novice paramedics. The participants performed tracheal intubations using both TruView and MAC on a pediatric manikin in a control scenario (A), chest compression scenario (B), and chest compression cervical stabilization scenario (C). The sequence of scenarios was randomized. The primary outcome was time to intubation. Secondary outcomes were overall success rates, incidence of dental trauma, and ease of intubation. All intubation attempts were assessed by a trained assistant. The overall success rate was significantly higher with the TruView compared than the MAC in scenario B (100 vs. 81.7 %; p?=?0.011) and scenario C (100 vs. 68.3 %; p?<?0.001). The intubation time was significantly lower with the TruView than the MAC (18.5 vs. 24.3 s, p?=?0.017, for scenario A; 21.6 vs. 25.7 s, p?=?0.023, for scenario B; and 28.9 vs. 45.4 s, p?<?0.001, for scenario C). Glottic view quality was better with TruView than the MAC in all scenarios, p?<?0.001.The TruView offers better intubation conditions than the MAC on a pediatric manikin in the control scenario, chest compression scenario, and chest compression scenario with cervical stabilization scenario. The TruView may be used to elevate the epiglottis for orotracheal intubation. Further clinical studies are necessary to confirm these initial positive findings.clinicaltrials.gov Identifier: NCT02289872.•Prehospital pediatric intubation using a standard laryngoscope is varied and ranges from 63.4 to 82 %. What is New: •This is the first study showing efficiency of pediatric endotracheal intubation using the TruView PCD by paramedics in tree simulation scenarios. •TruView PCD offers better pediatric intubation conditions than the Macintosh laryngoscope.

Project description:BackgroundEndotracheal intubation (ETI) can be challenging, especially in life-threatening situations such as cardiopulmonary resuscitation (CPR). Videolaryngoscopes aim to ease ETI, but effort is still widely discussed. This study intended to investigate 2 different airway devices regarding the success rate of ETI during ongoing chest compressions.MethodsThis randomized, cross-over, multi-center manikin trial included 85 experienced paramedics actively working in the emergency medicine service. After a standardized training session, all paramedics underwent 3 airway scenarios using both, direct laryngoscopy using a Macintosh blade and videolaryngoscope (the UEScope): normal airway without chest compressions, normal airway with uninterrupted chest compressions, and difficult airway with uninterrupted chest compressions. The primary outcome was successful ETI, defined as successful placement of the endotracheal tube within the manikin's trachea. Secondary outcomes were number of intubation attempts, time to successful ETI, time to best glottis view, best percent of glottic opening, best glottic view score (Cormack and Lehane), occurrence of dental trauma, ease of use, and willing to reuse in real-life situations.ResultsThe UEScope provided a better glottis visualization, and higher first pass intubation success rate compared to direct laryngoscopy in all 3 scenarios. The overall intubation success was higher, and the intubation time was shorter with the UEScope in scenario B and scenario C, but was comparable in scenario A. Dental compression occurred less often using the UEScope and paramedics rated intubation using the UEScope easier compared to direct laryngoscopy in all 3 airway scenarios.ConclusionIn simulated CPR scenarios, intubation with the UEScope resulted in a better glottis visualization, a higher intubation success, and a shorter intubation time compared to Macintosh laryngoscope (MAC). Moreover, in situations where the airway is difficult for ETI especially by the paramedic, the UEScope would be a better choice than the MAC. Further studies are needed to confirm these results in real-life patients.

Project description:A variety of instruments are used to perform airway management by tracheal intubation. In this study, we compared the MacIntosh balde (MB) laryngoscope with the Bonfils intubation fibrescope as intubation techniques. The aim of this study was to identify the technique (MB or Bonfils) that would allow students in their last year of medical school to perform tracheal intubation faster and with a higher success probability. Data were collected from 150 participants using an airway simulator ['Laerdal Airway Management Trainer' (Laerdal Medical AS, Stavanger, Norway)]. The participants were randomly assigned to a sequence of techniques to use. Four consecutive intubation 'trials' were performed with each technique. These trials were evaluated for differences in the following categories: the 'time to successful ventilation', 'success probability' within 90 s,'time to visualisation' of the vocal cords (glottis), and 'quality of visualisation' according to the Cormack and Lehane score (C&L, grade 1-4). The primary endpoint was the 'time to successful ventilation'in the fourth and final trial.There was no statistically significant difference in the 'time to successful ventilation' between the two techniques in trial 4 ('time to successful ventilation': median: MB: 16 s, Bonfils: 14 s, p = 0.244). However, the 'success probability' within 90 s was higher when using a Macintosh blade than when using a Bonfils (95 vs. 87%). The glottis could be better visualised when using a Bonfils (C&L score of 1 (best view): MB: 41%, Bonfils: 93%), but visualisation was achieved more rapidly when using a Macintosh blade (median: 'time to visualisation': MB: 6 s, Bonfils: 8 s, p = 0.003).The time to ventilation using the MacIntosh blade and Bonfils mainly did to differ, however success probabilities and time to visualisation primary favoured the MacIntosh blade as intubation technique, although the Bonfils seem to have a steeper learning curve. The Bonfils is still a promising intubation technique and might be easier to learn as the MB, at least in a manikin.
