We hypothesized that because the view of the glottis is better with videolaryngoscopes, successful intubation in neonates would be accomplished in a shorter time with the GlideScope (®) (Verathon, Inc., Bothell, WA) videolaryngoscope (GVL). Forty-five students of the University of Athens, inexperienced in both techniques, participated in the study (21 medical students and 24 nursing students, crossover randomized study). Following a brief educational session, each participant practiced and attempted intubation on a neonatal manikin using conventional laryngoscope and GVL, as many times as required to secure the airway. The time required to successful intubation and the number of attempts with each device were recorded. No significant difference was observed between the number of attempts required for successful intubation with either laryngoscope. The time required for the first successful intubation with the conventional laryngoscope was significantly shorter compared with that required with the GVL ( P = 0.0013). There was no difference regarding the time required for the successful intubation between medical and nursing students, using the conventional laryngoscope or the GVL. The number of attempts to successful intubation with either device did not differ. The time required for intubation with the GVL was longer, and this is probably due to a design flaw.
我们假设，由于视频喉镜能够提供更好的声门视图，因此使用 GlideScope（®）（Verathon，Inc.，Bothell，WA）视频喉镜（GVL）进行新生儿插管会在更短的时间内完成。雅典大学的 45 名学生（21 名医学生和 24 名护理学生，交叉随机研究），对这两种技术都不熟悉，参与了这项研究。在简短的教育课程之后，每位参与者都使用常规喉镜和 GVL 在新生儿模型上进行了练习和尝试插管，直到确保气道通畅为止。记录了成功插管所需的时间和使用每种设备的尝试次数。两种设备均未观察到成功插管所需的尝试次数之间存在显著差异。与 GVL 相比，使用常规喉镜进行首次成功插管所需的时间明显更短（P = 0.0013）。使用常规喉镜或 GVL，医学和护理学生成功插管所需的时间没有差异。使用任何一种设备进行成功插管所需的尝试次数均无差异。使用 GVL 进行插管所需的时间更长，这可能是由于设计缺陷所致。
