ABSTRACT
Objective:
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.
