Abstract Objective: To observe the effects of electronic bronchoscopy-guided stent placement on blood gas indexes, shortness of breath, and pulmonary function in patients with malignant airway stenosis. Methods: A total of 120 patients with malignant airway stenosis who were treated with electronic bronchoscopy-guided stent placement were included in this study. The success rate of one-time placement, complications and 6-month postoperative survival were observed. Blood gas indexes [partial pressure of oxygen (PaO₂), partial pressure of carbon dioxide (PaCO₂) and oxygen saturation (SaO₂)], classification of shortness of breath, pulmonary function indicators [forced expiratory volume in 1s (FEV1), forced vital capacity (FVC) and peak expiratory flow (PEF)], and ECOG score were compared before and after treatment. Results: The success rate of one-time placement was 96.67%. After operation, there were 3 patients with obvious bloody phlegm, 9 patients with a little blood in sputum, and 8 patients with mild substernal pain, which all disappeared after symptomatic treatment. After treatment, dyspnea in all patients was relieved significantly. 21 (17.5%) patients died from the primary disease in 6 months after operation. After treatment, PaO₂ and SaO₂ increased significantly (P<0.05), and PaCO₂ decreased significantly (P<0.05). Shortness of breath was significantly improved (P<0.05). FEV1, FVC and PEF increased significantly (P<0.05), and ECOG score decreased significantly (P<0.05). Conclusion: Electronic bronchoscopy-guided stent placement is safe and effective in the treatment of malignant airway stenosis. It can significantly improve blood gas indexes, shortness of breath and pulmonary function.
