Abstract

Background and Aims: Videolaryngoscopes have attained prime importance in securing the airway in children in the present era. McGrath videolaryngoscope is available with single-use non-channeled fog-free disposable blades of various sizes showing its efficacy for intubation in adults but still lacunae in data related to children. Materials and Methods: In this prospective randomized controlled trial, a total of 88 children of the American Society of Anesthesiologists Grade I and II aged 1–10 years, weighing 10–20 kg undergoing general anesthesia were enrolled. Using the sealed envelope technique, the children were randomly allocated between Group G, in whom McGrath videolaryngoscope and Group M, in whom Macintosh laryngoscope was used for intubation. The primary aim was to compare intubation time between the two videolaryngoscopes. The secondary outcomes included glottic exposure time, Cormack and Lehane grading, number of attempts of intubation, intubation difficulty scale and complications. Statistical analysis was done using MedCalc software. The Student's t-test and Chi-square test were used for quantitative and categorical data, respectively. Results: The mean intubation time was comparable in both the groups (18.14 ± 17.80 s in Group G vs. 17.30 ± 16.74 s in Group M, P = 0.821). The mean time to glottic exposure was shorter (5.66 ± 4.58 vs. 8.50 ± 5.59 s, P = 0.0108) with decreased number of attempts of tube insertion and less incidences of trauma observed in patients with Group G as opposed to Group M. The Cormack and Lehane grading showed better glottic view in Group G. Conclusion: McGrath videolaryngoscope is as useful as the Macintosh laryngoscope for intubation in children with the added advantages of a better view of the larynx, lesser attempts to intubation, and fewer incidence of trauma.
McGrath视频喉镜与传统Macintosh喉镜用于气道正常儿童气管插管的比较
背景和目的:在当今时代,视频喉镜在儿童气道安全方面发挥着至关重要的作用。McGrath视频喉镜可提供各种尺寸的一次性非通道无雾一次性刀片,显示出其对成人插管的疗效,但与儿童相关的数据仍存在空白。材料和方法:在这项前瞻性随机对照试验中,共有88名美国麻醉师学会一级和二级儿童,年龄1-10岁,体重10-20 kg,接受全身麻醉。使用密封封套技术,将儿童随机分为G组和M组,G组使用McGrath视频喉镜,M组使用Macintosh喉镜进行插管。主要目的是比较两种视频喉镜的插管时间。次要结果包括声门暴露时间、Cormack和Lehane分级、插管次数、插管困难程度和并发症。使用MedCalc软件进行统计分析。学生t检验和卡方检验分别用于定量和分类数据。结果:两组的平均插管时间相当(G组18.14±17.80 s,M组17.30±16.74 s,P=0.021)。声门暴露的平均时间较短(5.66±4.58,8.50±5.59 s,P=0.0108),G组与M组相比,插管次数减少,创伤发生率降低。在G组中,Cormack和Lehane分级显示出更好的声门视野。结论:McGrath视频喉镜与Macintosh喉镜一样适用于儿童插管,还具有更好的喉视野、更少的插管尝试和更少的创伤发生率等优点。
