ABSTRACT

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has drastically affected hospital and operating room (OR) workflow around the world as well as trainee education. Many institutions have instituted mandatory preoperative SARS-CoV-2 PCR nasopharyngeal swab (NS) testing in patients who are low risk for COVID-19 prior to elective cases. This method, however, is challenging as the sensitivity, specificity, and overall reliability of testing remains unclear. OBJECTIVES: The objective of this study was to assess the concordance of a negative NS in low risk preoperative patients with lower airway bronchoalveolar lavage (BAL) specimens obtained from the same patients. METHODS: We prospectively sent intraoperative lower airway BAL samples collected within 48 h of a negative mandatory preoperative NS for SARS-CoV-2 PCR testing. All adult patients undergoing a scheduled bronchoscopic procedure for any reason were enrolled, including elective and nonelective cases. RESULTS: One-hundred eighty-nine patients were included. All BAL specimens were negative for SARS-CoV-2 indicative of 100% concordance between testing modalities. CONCLUSIONS: These results are promising and suggest that preoperative nasopharyngeal SARS-CoV-2 testing provides adequate screening to rule out active COVID-19 infection prior to OR cases in a population characterized as low risk by negative symptom screening. This information can be used for both pre-procedural screening and when reintroducing trainees into the workforce.

ABSTRACT

Severe Acute Respiratory Syndrome due to Coronavirus-19 (SARS-CoV-2) is caused by combined alveolar-capillary lung damage, with bilateral pneumonia and thrombosis, which often causes respiratory failure. Proper COVID-19 management requires high skills in airway control and the need to perform aerosol-generating procedures such as bronchoscopy, which can increase the possibility of virus spreading among healthcare professionals. In an epidemiologically delicate moment, the multidisciplinary decision on "WHEN, HOW and WHY" to perform bronchoscopies minimizing the risk of COVID-19 transmission, represented a great challenge for all specialists engaged in bronchoscopic procedures. In this work authors want to share all technical aspects of 87 videobronchoscopies performed in confirmed or suspected COVID-19 patients, from 3rd to 6th January 2020, describing the reason, the organizational and operational model and patients characteristics. Was also evaluated the impact of high-risk procedures such as bronchoscopy on the personnel involved. The disclosure of all technical details, represents, in the opinion of the authors, an important contribution, capable of providing support to all physicians engaged in bronchoscopy procedures in confirmed or suspected COVID-19 patients.
