Corresponding Factors And Prevention Strategies Of Ventilator Associated Pneumonia

ObjectiveTo investigate risk factors of ventilator-associated pneumonia and to provide the corresponding clinical prevention strategies.MethodsA retrospective study was conducted in patients who had received mechanical ventilation more than 48 hours in general surgery intensive care unit from 2000 to 2006.Chi-square test and t test were adopted to ananlyze the VAP risk factors.Results77 patients were enrolled in this study, 32 patients had VAP, the morbidity was 41.56%. Blood glucose and the time of nose-stomach tube laid up in VAP group were significantly higher than in non-VAP group, ventilator circuit change period in VAP group were significantly shorter than in non-VAP group. Sex and age of patients and antibiotics therapy and the level of the serum albumin and the APACHEâ…¡score have no significant difference in the two groups.ConclusionsTo keep the blood glucose of patients under control, shorten the time of nose-stomach tube laid up and prolong the ventilator circuit changed period can reduce the morbidity of VAP.
