【 摘 要 】

ABSTRACTObjective: To describe the indications and endoscopic findings of bronchoscopy performed at a reference university hospital for inpatients diagnosed with COVID-19 during the first outbreak of the disease in Brazil.Methods: A retrospective analysis of medical records of adult patients diagnosed with COVID-19 who underwent bronchoscopy at the intensive care units of Instituto do Coração and Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, from March to August 2020.Results: A total of 132 bronchoscopies were performed in 103 patients diagnosed with COVID-19. Mean age was 56.1±14.5 years, and distribution was similar in both sexes. More than one test was performed in 16 patients. The most frequent indications were diagnostic endoscopic evaluation and therapeutic procedures in 78.6% of cases (n=81) and material collection in 21.4% of cases (n=22). The most frequent endoscopic findings were presence of secretion or clots in 34% of cases, the presence of acute inflammatory changes in 22.3%, and tracheal wall laceration in 20.4%. In 27.2% of patients, no relevant bronchoscopic findings were observed. In three patients, bronchoscopy was indicated to assess hemoptysis, but there was only one case of active bleeding. Procedure-related complications were not observed in this group of patients.Conclusion: Bronchoscopy proved to be a safe and effective procedure to assist in treatment of COVID-19 patients, and the most frequent indications were related to investigation of airway involvement or to evaluate infectious and inflammatory pulmonary processes.
