About

Safety and efficacy of local instillation of Gentamicin and dexamethasone in acute exacerbation of bronchiectasis in mechanically ventilated patients

Full description

bronchiectasis is a chronic suppurative and inflammatory lung disease of diverse etiology characterized by pathological and irreversible dilatation of the bronchial tree. The impairment of the mucociliary clearance, which results from chronic airway inflammation, may cause long-term colonization or recurrent infection of bacteria, especially Pseudomonas aeruginosa (PA), while bacterial colonization and recurrent infection can aggravate airway inflammation. Sputum retention caused by the impairment of mucociliary clearance can result in mucous plugs, which in turn contribute to airflow obstruction and dyspnea.

Clinically, the major manifestations of bronchiectasis are chronic cough with purulent sputum, dyspnea, and fatigue that may diminish the patients' quality of life. The frequency of exacerbation and the decline in lung function may lead to poor prognosis and decrease quality of life.

The purpose of bronchiectasis management is to reduce exacerbation, prevent complications, and improve the quality of life. Long-term instillation of gentamicin can reduce the concentration of bacteria in the airways, decrease sputum production, attenuate lung function decline, and reduce acute pulmonary exacerbations without nephrotoxicity or ototoxicity. Dexamethasone is one of the most common glucocorticoids which can inhibit the expression levels of inflammatory factors in the airway and reduce the secretion of airway mucus. Topical administration could also reduce the systemic side effects.

Description:
this arm will include half number of cases(which will be 35 cases) selected in a randomized manner and will undergo bronchoscopic airway clearance followed by local instillation of gentamicin(80 mg once) and dexamethasone(5 mg) once.
Treatment:
Drug: bronchoscopic airway clearance followed by local instillation of gentamicin and dexamethasone
control group
No Intervention group
Description:
his arm will include the other half number of cases(35 cases) selected in a randomized manner and will receive only conventional treatment without intervention.
