Background. Tracheal stenosis is able to lead to airway obstruction. Objective. To evaluate the efficacy and safety profile of Montgomery T-tube implantation in patients with tracheal stenosis. Methods. Fifty-two patients with tracheal stenosis diagnosed between 2016 and 2019 were included in this retrospective cohort study. The patients were divided into observation group (n = 25 cases) and control group (n = 27). The therapeutic effect, arterial blood gas analysis, arterial oxygen partial pressure (PaO₂), arterial carbon dioxide partial pressure (PaCO₂), shortness of breath score, airway diameter change, dyspnea score, quality of life, and safety were compared between the two groups before and after treatment. Results. The therapeutic effect of the observation group gained better results than that of the control group (84.00% vs. 62.96%). One week after operation, the pH value, SaO₂, PaCO₂, shortness of breath score, airway diameter change, dyspnea score, life quality, and incidence of postoperative complications in the observation group exerted better results as compared to the control group. Conclusion. The implantation of Montgomery T-tube has effective function in terms of improving the symptoms of dyspnea and the life quality of patients with safety profile in patients harboring tracheal stenosis.

Montgomery T 形管植入气管狭窄患者的疗效和安全性

背景。气管狭窄能够导致气道阻塞。客观。评估蒙哥马利 T 管植入治疗气管狭窄患者的疗效和安全性。方法。该回顾性队列研究纳入了 2016 年至 2019 年间诊断的 52 名气管狭窄患者。将患者分为观察组（n  =25）和对照组（n  =27）。治疗效果、动脉血气分析、动脉氧分压（PaO ₂）、动脉二氧化碳分压（PaCO ₂)，比较两组治疗前后的气短评分、气道直径变化、呼吸困难评分、生活质量和安全性。结果。观察组治疗效果优于对照组（84.00% vs. 62.96%）。术后1周，观察组pH值、SaO ₂、PaCO ₂、气短评分、气道直径变化、呼吸困难评分、生活质量、术后并发症发生率均优于对照组。结论. 蒙哥马利T形管的植入在改善气管狭窄患者呼吸困难症状和患者生活质量方面具有有效作用，具有安全性。
