Efficacy of Intermittent Subglottic Secretion Lavage Combined With Aspiration Preventing Ventilator Associated Pneumonia in Patients With Severe Neurological Disease：A Single-center Randomized Controlled Trial
Efficacy of Intermittent Subglottic Secretion Lavage Combined With Aspiration Preventing Ventilator Associated Pneumonia in Patients With Severe Neurological Disease：A Single-center Randomized Controlled Trial
The purpose of this study is to determine the efficacy of intermittent subglottic secretion lavage combined with aspiration preventing ventilator associated pneumonia in patients with severe neurological disease
Ventilator-associated pneumonia (VAP) is a common and serious complication of mechanical ventilation. Many studies have shown that the accumulation of subglottic secretions above the endotracheal cuff plays an important role in the pathogenesis of VAP. Subglottic secretion drainage (SSD) has been shown to be associated with a lower incidence of VAP in previous meta-analyses. Most studies in past reported that in the group of patients in whom endotracheal tube (ETT) was used and subglottic secretion drainage was applied compared to the group without subglottic secretion drainage.Very few studies compared two different methods of SSD,such as subglottic secretion lavage combined with aspiration or pure aspiration.The tubes need frequent cleaning as they often get blocked, especially the draining duct. This may be the reason why they are not commonly applied. However,subglottic secretion lavage combined with aspiration can reduce the incidence of tube blockage.So The purpose of this study is to determine the efficacy of intermittent subglottic secretion lavage combined with aspiration preventing ventilator associated pneumonia in patients with severe neurological disease.
