摘要

目的 分析重症肺炎并呼吸衰竭以序贯机械通气开展临床治疗的效果。方法 选择我院2020年1月-2022年1月重症肺炎并呼吸衰竭患者共50例，数字表随机分2组每组25例，对照组的患者给予有创机械通气治疗，观察组采取有创机械通气-无创机械通气序贯治疗。比较两组机械通气总治疗时间、住院时间、治疗前后患者肺功能、氧合指数、氧分压、二氧化碳分压、总有效率。结果 观察组机械通气总治疗时间、住院时间短于对照组，治疗后患者肺功能、氧合指数、氧分压高于对照组，二氧化碳分压低于对照组，总有效率高于对照组，P＜0.05。结论 有创机械通气-无创机械通气序贯治疗对于重症肺炎并呼吸衰竭的治疗效果确切。

Abstract

Objective: To analyze the effect of sequential mechanical ventilation in the clinical treatment of severe pneumonia complicated with respiratory failure.
Methods: A total of 50 patients with severe pneumonia and respiratory failure in our hospital from January 2020 to January 2022 were selected and randomly divided into 2 groups with 25 cases in each group. Invasive mechanical ventilation - sequential treatment with non-invasive mechanical ventilation. The total treatment time, hospital stay, pulmonary function, oxygenation index, partial pressure of oxygen, partial pressure of carbon dioxide, and total effective rate were compared between the two groups before and after treatment.
Results: The total treatment time and hospitalization time of mechanical ventilation in the observation group were shorter than those in the control group. After treatment, the pulmonary function, oxygenation index and partial pressure of oxygen in the patients were higher than those in the control group, and the partial pressure of carbon dioxide was lower than that in the control group. The total effective rate was higher than that in the control group. P<0.05.
Conclusion  : The sequential treatment of invasive mechanical ventilation and non-invasive mechanical ventilation is effective in treating severe pneumonia and respiratory failure.
