Objective: To investigate the clinical value of double catheter modified bronchoalveolar lavage (BAL) in the diagnosis of ventilator associated pneumonia.Methods: 60 cases of the patients diagnosed with VAP were selected and grouped according to the random principle. Microbiological diagnosis was made on the sputum obtained from 3 respiratory specimens methods. The common suction tube or closed suction tube method was adopted in group A (n=20), the modified bronchoalveolar lavage was adopted in group B (n=20) and the fiberoptic bronchoscopy bronchoalveolar lavage was adopted in group C (n=20). The diagnostic sensitivity, specificity, positive predictive value, negative predictive value and other clinical cost index were compared between the three groups.Results: The diagnostic sensitivity, specificity and positive predictive value in group A were better than those in group B and group C (P＜0.05); the negative predictive value in group A was higher than that in group B and group C (P＜0.05); there was no significant difference of the four indicators in group B and C (P＞0.05). There was no significant difference in average material cost, average drug fee, average monitoring fee and other expenses between the three groups (P＞0.05).Conclusion: Double catheter modified bronchoalveolar lavage is of high diagnostic value for ventilator-associated pneumonia, and the clinical cost is not high. It is worth popularizing in the acceptable range.
