Influencing Factors and Prevention of Ventilator Associated Pneumonia

Objective: To study the incidence and influential factors of early onset and late onset ventilator associated pneumonia in patients using mechanical ventilation. Methods: The clinical data of 295 patients who were hospitalized from June 2012 to June 2013 treated with mechanical ventilation were investigated by using a self-designed questionnaire. Among them,92 cases suffering from ventilator associated pneumonia were assigned into the research group,and the rest into the control group. The possible influencing factors of ventilator associated pneumonia in the patients were analyzed by logistic regression analysis. Results: Statistical differences were found in the diagnosis index results of early and late ventilator-associated pneumonia( P 0. 05 for both). By logistic regression analysis,we found that age,breathing time,ventilation mode,serum albumin,airway humidification,bed rest position,blood glucose and serum albumin levels. Conclusion: The following measures were adopted to reduce the incidence of ventilator-associated pneumonia,including shortening the time,strengthening basic care,paying attention to the management of respiratory tract.
