由于2019年冠状病毒病(COVID-19)的高度传染性,气管插管对医务人员造成感染的高风险。为了减轻这种风险,各种医疗设备,包括视频喉镜,已经发展到辅助插管。这项研究比较了常规喉镜(Macintosh)和一次性视频喉镜(MedcaptainVS-10s和Honestmc喉镜_LA10000)的使用和操作过程。我们设计了一份问卷,以评估操作员对使用设备进行插管的感知,对来自2家医院的50名进行过插管或学习过插管技术的临床工作人员进行了统计分析。主要结果是声门可视化时间,插管时间,插管成功率,操作员和培训模型之间的距离,从声门可视化到管插入的时间。次要结果如下:喉镜整体质量,操作感觉,机动性,易用性,和视频质量。这项研究表明,视频喉镜在质量方面优于传统喉镜,操作感觉,和易用性。当LA10000被雇用时,插管成功率较高,并且由于与训练模型的距离较大,因此操作员感染的风险较低。然而,视频喉镜的使用需要适当的教育和培训设备的使用。这项研究还表明,当参与者在使用视频喉镜之前观看简单的手术视频时,插管时间较短。总的来说,视频喉镜检查可以为临床医务人员在大流行期间提供更安全,更方便的选择。
Tracheal intubation poses a high risk of infection to medical staff due to Coronavirus disease 2019 (COVID-19) highly infectious nature. To mitigate this risk, various medical devices, including video laryngoscopy, have been developed to assist intubation. This study compared conventional laryngoscopy (Macintosh) and disposable video
laryngoscopes (Medcaptain VS-10s and Honestmc Laryngoscope_LA10000) in terms of their use and operation processes. We designed a questionnaire to assess the operator perception of performing intubation with the devices, and statistical analysis was performed on 50 clinical staff members from 2 hospitals who had performed intubation or had learned intubation techniques. The primary outcomes were time to glottic visualization, intubation time, intubation success rate, distance between the operator and training model, and time from glottic visualization to tube insertion. The secondary outcomes were as follows: overall laryngoscope quality, operative feel, maneuverability, ease of use, and video quality. This study showed that video
laryngoscopes were superior to conventional
laryngoscopes in terms of quality, operative feel, and ease of use. When LA10000 was employed, the intubation success rate was higher, and the operator risk of infection was lower because of the greater distance from the training model. However, the use of video
laryngoscopes requires appropriate education and training use of the devices. This study also demonstrated that when participants viewed a simple operation video prior to using video
laryngoscopes, tube insertion time was shorter. Overall, video laryngoscopy can provide a safer and more convenient option for clinical medical personnel during pandemics.
