Prevention of Ventilator-associated Pneumonia with Techknowdedge of Subglottic Secretion Clean up

Objective To study the effect of techknowledge of subglottic secretion clean up to reduce the rate of ventilator-associated pneumonia (VAP).Methods Fifty-eight patients were divided into two groups. The observation group (n=32) was treated with techknowledge of subglottic secretion clean up and the control group(n=26) received routine airway care. The rate of VAP in two groups in 7, 14 days and over 14 days and duration of mechanical ventilation were compared.Results The VAP incidence was significantly lower in 7 and 14 days and the duration of mechanical ventilation was shorter in the observation group than those in the control group (P0.05,P0.01), but no significant difference was found between two groups after 14 days (P0.05).Conclusion Techknowledge of subglottic secretion clean up can significantly reduce the rate of VAP, but subglottic secretion is not the only one factor for VAP.
