Application of combined tracheal tubes to the critical patients with mechanical ventilation

Objective To assess the influence of the subglottic secretion drainage on ventilator associated pneumonia (VAP) patients with mechanical ventilation.Methods The patients requiring tracheal intubation and mechanical ventilation for above 48 hours were randomly divided into two groups:A group received the ordinary tracheal tubes,B group received the combined tracheal tubes and regularly subglottic secretion drainage.The occurrence of VAP in two groups was observed and statistical analysis was made.Result Incidence rate of VAP was obviously higher in A group than in B group.Conclusion To avoid risk factors of VAP is a quite effective measure to reduce the incidence rate of VAP.The clinical application of combined tracheal tubes can effectively eliminate the subglottic secretion,reduce bacterial planting rate in the respiratory tract,and is proved to be a quite effective measure to prevent VAP.
