Bronchoscopy is an aerosol-generating procedure that creates unique challenges for healthcare providers to reduce the potential spread of the COVID-19 respiratory pathogen. As part of the initial response, Cleveland Clinic postponed elective surgeries including bronchoscopy. ⋯ When elective bronchoscopies were resumed, we established protocols to reduce aerosolization and potential virus transmission risks such as using an airborne infection-isolation room and changing to total intravenous anesthesia. Also, we established guidelines for periprocedural care and use of personal protective equipment including requirements for wearing N95 masks for all bronchoscopy procedures.

Severe COVID-19 illness is associated with intense inflammation, leading to high rates of thrombotic complications that increase morbidity and mortality. Markedly elevated levels of D-dimer with normal fibrinogen levels are the hallmark laboratory findings of severe COVID-19- associated coagulopathy. Prophylaxis against venous thromboembolism is paramount for all hospitalized patients, with more aggressive prophylaxis and screening recommended for patients with D-dimer levels above 3.0 μg/mL. Point-of-care ultrasonography is the imaging method of choice for patients at high risk, as it entails minimal risk of exposing providers to the virus.

The typical findings of COVID-19 on chest radiography and computed tomography (CT) include bilateral, multifocal parenchymal opacities (ground-glass opacities with or without consolidation, and "crazy paving"). In most cases, the opacities are predominantly in the peripheral and lower lung zones, and several have rounded morphology. However, these imaging findings are not pathognomonic for COVID-19 pneumonia and can be seen in other viral and bacterial infections, as well as with noninfectious causes such as drug toxicity and connective tissue disease. Most radiology professional organizations and societies recommend against routine screening CT to diagnose or exclude COVID-19.

Acute, uncomplicated rhinosinusitis is a clinical diagnosis. Imaging should only be used in the case of complicated sinus infections, recurrent or chronic sinus disease, or in surgical planning. The authors discuss key features of complicated and uncomplicated rhinosinusitis, management, and recommendations on the use of imaging in diagnosis.
