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.

•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.
本研究的目的是评估在三种基于人体模型的气道场景中,TruView视频喉镜(TruView)相较于传统麦金托什喉镜(MAC),是否能更快速、安全地辅助小儿气管插管(ETI)。这是一项随机交叉人体模型研究,纳入了120名新手护理人员。参与者在控制场景(A)、胸部按压场景(B)和胸部按压颈椎固定场景(C)中,使用TruView和MAC对小儿人体模型进行气管插管。场景顺序是随机的。主要结局是插管时间。次要结局包括总体成功率、牙齿损伤发生率和插管难易程度。所有插管尝试均由一名经过培训的助手进行评估。在场景B中,TruView的总体成功率显著高于MAC(100%对81.7%;p = 0.011),在场景C中也是如此(100%对68.3%;p < 0.001)。TruView的插管时间显著短于MAC(场景A中为18.5秒对24.3秒,p = 0.017;场景B中为21.6秒对25.7秒,p = 0.023;场景C中为28.9秒对45.4秒,p < 0.001)。在所有场景中,TruView的声门视野质量均优于MAC,p < 0.001。
在控制场景、胸部按压场景以及胸部按压颈椎固定场景中,TruView在小儿人体模型上提供了比MAC更好的插管条件。TruView可用于抬起会厌以进行口气管插管。需要进一步的临床研究来证实这些初步的阳性结果。
