Observation and nursing of subglottic secretion drainage regularly to preven ventilator-associated pneumonia

Objective:To study the effects of regularly subglottic secretion drainage(SSD) on preventiving ventilator-associated pneumonia(VAP).Methods:102 patients treated by mechanical ventilation with nasal/oral tracheal intubation were randomly observation group and control group.The patients of observation group were assigned to receive either an endotracheal tube for regularly subglottic secretion drainage(n=52),the patients of the other group drainaged secretion by a standard endotracheal tube(n=50).The incidence of VAP of two groups were observed.Results:The incidence of VAP in observation group was 26.9%,while,the average onset time of VAP was 14±3 days,that of control group were 58.0% and 6±4 days respectively.There was significant difference between two groups(P0.05).Conclusion:Subglottic secretion drainage with an endotracheal tube regularly can effectively reduce the incidence of VAP in patients receiving mechanical ventilation.
