The goals: To evaluate effectiveness of the method using continuous aspiration of subglottic secretions in preventing from ventilator-associated pneumonia. Objects and method: from 9/2009 to 9/2010 at the Emergency Department and ICU Bach Mai hospital, there were 25 patients who had met all the criteria selected to the study and the patients were divided into two groups: 12 patients who were randomized to receive continuous aspiration of subglottic secretions called the study group, and the other 13 patient were involved in the control group with the conventional care.
