high flow nasal cannula, airway stent, nebulized saline
Brief summary
The application of HFNC therapy in patients with airway stent, improving both humidification and clearance of the airway secretion, could potentially reduce the risk of mucoid impaction, respiratory infections and granulation. HFNC therapy could be superior to nebulization of normal saline (usual care) in order to keep the stent cleaned, reducing, by inference, the risk of complications, as defined above.
Interventions
home treatment with HFNC after airway stent placement both for malignant and benignant central airway obstruction
home treatment with nebulized normal saline after airway stent placement both for malignant and benignant central airway obstruction

| incidence of mucous plugging associated with airway stent in nebulized saline group | within 7 days from stent placement | mucous plugging assessed during bronchoscopy, eventually determining reduction in cross-sectional stent area |
| incidence of granuloma associated with airway stent in HFNC group | within 90 days from stent placement | granuloma formation assessed during bronchoscopy, eventually determining reduction in cross-sectional stent area |
| incidence of granuloma associated with airway stent in nebulized saline group | within 7 days from stent placement | granuloma formation assessed during bronchoscopy, eventually determining reduction in cross-sectional stent area |
| incidence of respiratory infection associated with airway stent in HFNC group | within 90 days from stent placement | symptoms of respiratory infection + radiologic and/or bronchoscopic signs of infection + need of antibiotic therapy |
| incidence of respiratory infection associated with airway stent in nebulized saline group | within 90 days from stent placement | symptoms of respiratory infection + radiologic and/or bronchoscopic signs of infection + need of antibiotic therapy |
Secondary

| adherence to home treatment with HFNC in patients with airway stent, as assesed by time of daily utilization | within 90 days from stent placement | minutes a day spent on HFNC |
| mortality due to respiratory infection in HFNC group | within 90 days from stent placement | — |
| mortality due to respiratory infection in nebulized saline group | within 90 days from stent placement | — |
| all cause-mortality in nebulized saline group | within 90 days from stent placement | — |
| adherence to home treatment with nebulization of normal saline in patients with airway stent, as assesed by time of daily utilization | within 90 days from stent placement | times a day spent on nebulization |
| incidence of adverse events due to home treatment with HFNC in patients with airway stent | within 90 days from stent placement | incidence of malfunction of the device; incidence of complications as assessed by clinical examination (cough, headache, rhinitis) |
| incidence of adverse events due to home treatment with nebulization of normal saline in patients with airway stent | within 90 days from stent placement | incidence of malfunction of the device; incidence of complications as assessed by clinical examination (cough, headache, rhinitis) |
| Satisfaction of home treatment with HFNC by Cough and sputum assessment questionnaire (CASA-Q) | within 90 days from stent placement | Cough and sputum assessment questionnaire (CASA-Q) to evaluate both severity of cough and sputum production to quality of life impairment (minimum value 0, maximum value 100; higher scores mean worse outcome) |
| Satisfaction of home treatment with nebulized saline by Cough and sputum assessment questionnaire CASA-Q | within 90 days from stent placement | Cough and sputum assessment questionnaire (CASA-Q) to evaluate both severity of cough and sputum production to quality of life impairment (minimum value 0, maximum value 100; higher scores mean worse outcome) |
