Abstract:
Objective:To investigate the difference between bronchoalveolar lavage fluid (BALF) and tracheal aspirate (TA) on the use of antibiotics in patients with severe pneumonia.
Methods:Patients with severe pneumonias admitted to the Department of General Intensive Care Unit of Second Affiliated Hospital of Zhejiang University School of Medicine, between December 2014 and March 2019 were retrospectively analyzed. The difference of effects of BLAF and TA on the use of antibiotics in patients with severe pneumonia were compared and analyzed, as well as the effects of antibiotic de-escalation on patient’s mortality were evaluated. The quantitative data were analyzed by independent sample t test, and the enumeration data were determined by Chi-square test or Fisher exact probability method.
Results:Among the 120 patients, more bacteria were detected in BALF than in TA (82 vs 60, P<0.05). More fungi were detected in BALF than in TA (20 vs 3, P<0.05). Compared with TA, BALF results were more likely to guide the adjustment of antibiotic regimens (41 vs 16, P<0.05), including guidance for antibiotics de-escalation (27 vs 9, P<0.05). There was no significant difference in the 14-day mortality, 28-day mortality, hospital stay and duration of mechanical ventilation between the two groups (all P<0.05).
Conclusions:Compared with TA, BALF, as a pathogens detection method for severe pneumania, has more advantages in guiding antibiotics administration, including antibiotic de-escalation, which will not increase the mortality of patients.
