使用全面型防护面罩(带正压)与一次性使用头罩(非正压)对新型冠状病毒肺炎重症患者行气管插管的影响

Effects of using all⁃round protective mask(positive pressure)or disposable hood(non⁃positive pressure)on tracheal intuba⁃tion in patients with severe COVID⁃19

目的探讨麻醉医师使用全面型防护面罩(带正压)与一次性使用头罩(非正压)对新型冠状病毒肺炎重症患者行气管插管的影响。方法回顾性纳入2020年2月16日至2月29日武汉市第一医院20例新型冠状病毒肺炎患者行气管插管的相关资料,其中9例气管插管时麻醉医师穿戴全面型防护面罩(带正压)设为面罩带正压组,11例气管插管时麻醉医师穿戴一次性使用头罩(非正压)设为头罩非正压组,收集2组气管插管所耗时长及麻醉医师进行气管插管时的焦虑评分、插管满意度、面屏是否起雾、是否有明显憋闷感等情况。结果面罩带正压组麻醉医师进行气管插管时的焦虑评分明显低于头罩非正压组(P<0.05),两组行气管插管所耗时长、插管满意度、面屏起雾以及明显憋闷感等方面差异无统计学意义(P>0.05)。结论全面型防护面罩(带正压)与一次性使用头罩(非正压)比较,在一定程度上能使麻醉医师减轻焦虑感,二者在气管插管所耗时长以及插管满意度上能达到相同的效果,二者在短时间内(小于30 min)佩戴均不会出现面屏起雾和明显憋闷感。

Objective To discuss the effects of using all‑round protective mask(positive pressure)or disposable hood(non‑positive pressure)on tracheal intubation in patients with severe COVID‑19.Methods Twenty COVID‑19 patients who underwent endotracheal intubation from February 16 to February 29,2020 were retrospectively enrolled,including an all‑round protective mask(positive pressure)group with 9 anesthesiologists wearing all‑round protective mask(positive pressure)and a disposable hood(non‑positive pressure)group with 11 anesthesiologists wearing disposable hood(non‑positive pressure).Then,the following data were collected:the time‑consuming of tracheal intubation,anxiety score during tracheal intubation,endotracheal intubation satisfaction,the presence of screen fogging and obvious suffocation.Results Anesthesiologists in the all‑round protective mask(positive pressure)group presented remarkably lower anxiety scores of tracheal intubation than those in the disposable hood(non‑positive pressure)group(P<0.05).There was no significant difference in intubation time‑consuming,satisfaction,screen fogging and obvious feeling of suffocation between the two groups(P>0.05).Conclusions Compared to disposable hood(non‑positive pressure),all‑round protective mask(positive pressure)can relieve the anxiety of anesthesiologists to some extent.Both of them can achieve the same effects on the time‑consuming and satisfaction of endotracheal intubation.Within a short period of time(less than 30 min),no screen fogging and obvious feeling of suffocation appear in the two groups.
