ABSTRACT
BACKGROUND: Although the imaging features of coronavirus disease 2019 (COVID-19) are starting to be well determined, what actually occurs within the bronchi is poorly known. Here, we report the processes and findings of bronchoscopy in a patient with COVID-19 accompanied by respiratory failure.
CASE SUMMARY: A 65-year-old male patient was admitted to the Hainan General Hospital on February 3, 2020 for fever and shortness of breath for 13 d that worsened for the last 2 d. The severe acute respiratory syndrome coronavirus 2 nucleic acid test was positive. Routine blood examination on February 28 showed a white blood cell count of 11.02 × 109/L, 86.9% of neutrophils, 6.4% of lymphocytes, absolute lymphocyte count of 0.71 × 109/L, procalcitonin of 2.260 ng/mL, and C-reactive protein of 142.61 mg/L. Oxygen saturation was 46% at baseline and turned to 94% after ventilation. The patient underwent video bronchoscopy. The tracheal cartilage ring was clear, and no deformity was found in the lumen. The trachea and bilateral bronchi were patent, while the mucosa was with slight hyperemia; no neoplasm or ulcer was found. Moderate amounts of white gelatinous secretions were found in the dorsal segment of the left inferior lobe, and the bronchial lumen was patent after sputum aspiration. The right inferior lobe was found with hyperemia and mucosal erosion, with white gelatinous secretion attachment. The patient's condition did not improve after the application of therapeutic bronchoscopy.
CONCLUSION: For patients with COVID-19 and respiratory failure, bronchoscopy can be performed under mechanical ventilation to clarify the airway conditions. Protection should be worn during the process. Considering the risk of infection, it is not necessary to perform bronchoscopy in the mild to moderate COVID-19 patients .
