目的:探讨气管插管前面罩加压预充纯氧对重症患者并发呼吸衰竭预后的影响。方法:采用对比研究,设置对照组(A组)和观察组(B组)。A组为危重病人并发呼吸衰竭达插管指征后即刻气管插管者;B组先予面罩加压给纯氧,待血氧饱和度达80%～90%以上时再行气管插管。在插管过程中监测血氧饱和度,随时给氧,保持血氧饱和度在70%～80%以上。结果:A组插管过程中心律失常发生率明显高于B组;A组后期MODS发生率、病死率高于B组。结论:气管插管前预充纯氧能降低插管过程中的不良反应,提高复苏质量,改善预后。
Objective: To investigate the influence of pre-intubation and nasal insufflation oxygen on the prognosis of critically ill patients with respiratory failure. Methods: By contrast study, set the control group (A group) and observation group (B group). A group of critically ill patients complicated by respiratory failure up to intubation indications immediately tracheal intubation who; B group to the mask pressure to pure oxygen, until the oxygen saturation of 80% to 90% or more when the tracheal intubation. During the intubation process to monitor oxygen saturation, oxygen at any time to maintain oxygen saturation at 70% to 80%. Results: The incidence of arrhythmia during intubation in group A was significantly higher than that in group B. The incidence of MODS and mortality in group A were higher than those in group B at the later stage. Conclusion: Pre-filled with pure oxygen before tracheal intubation can reduce adverse reactions during intubation, improve the quality of recovery and improve prognosis.
