Abstract:
Objective To explore the effects of bronchoalveolar lavage combined with microbiological rapid on-site evaluation in potential donor lung maintenance.Methods Brain death patients who met the inclusion criteria and were admitted to the Intensive Care Unit(ICU)of Calmette Hospital Affiliated to Kunming Medical University from September 2020 to December 2022 were selected for bronchoalveolar lavage(BAL)and(BAL)and the lavage fluid were collected for M-ROSE to compare the pathogen detection rate and initial diagnosis time.According to the positive results of the microbiological rapid on-site evaluation,patients with the brain death were treated with empirical anti-infective therapy,and the oxygenation index,chest X-ray score,and the infection index(WBC,CRP,PCT)of anti-infective treatment 48 hours were evaluated.Results 1.Comparison of the detection rate of pathogenic microorganisms:The results of M-ROSE were highly consistent with a routine microbiological smear(Kappa = 0.921,P<0.001).2.Comparison of diagnostic time:The initial diagnosis time of M-ROSE was significantly lower than routine microbiological smear time and microbial culture time(P<0.001).3.Comparison of therapeutic effects of anti-infective therapy for 48 hours:There was no significant difference in oxygenation index,white blood cells and hypersensitive C-reactive protein before and after the anti-infective treatment(P>0.05).There were significant differences in procalcitonin and chest X-ray before and after the anti-infective treatment(P<0.05).Conclusion Bronchoalveolar lavage combined with microbiological rapid on-site evaluation has the high timeliness in the diagnosis of potential donor pulmonary infection,which can provide a preliminary basis for the early anti-infective therapy of donor lung maintenance.
