BACKGROUND
Due to the high risk of COVID-19 transmission by asymptomatic patients, the aim of this study was to evaluate chest computed tomography (CT) and blood differential test as an additional COVID-19 screening tool for patients undergoing elective or urgent surgery.
PATIENTS AND METHODS
The preoperative assessment of 118 patients hospitalized from June to July 2020 included real-time reverse transcriptase polymerase chain reaction RNA test before elective surgery or rapid antigen test in emergency patients. The diagnostics were supplemented by chest CT and a complete blood count with a blood smear in all patients.
RESULTS
None of the hospitalized patients had molecular, serological or radiographic symptoms of COVID-19 infection. The chest CT revealed non-COVID-19 pathologies in a total of 48 patients. Leukocytosis and lymphopenia were typical of emergency patients.
CONCLUSION
Routine chest CT scans have no benefit in screening for potential COVID-19 changes in asymptomatic patients. Blood differential tests are readily available, which makes them more helpful in COVID-19 screening.
背景
由于无症状患者 COVID-19 传播的风险较高，本研究旨在评估胸部计算机断层扫描 (CT) 和血液差异检测作为接受择期或紧急手术患者的 COVID-19 额外筛查工具。
患者和方法
2020 年 6 月至 7 月住院的 118 例患者的术前评估包括择期手术前的实时逆转录酶聚合酶链反应 RNA 检测或急诊患者的快速抗原检测。所有患者均通过胸部 CT 和全血细胞计数加血涂片进行诊断。
结果
住院患者均无分子、血清学或影像学 COVID-19 感染症状。胸部 CT 总共显示 48 例非 COVID-19 病理学。白细胞增多和淋巴细胞减少是急诊患者的典型特征。
结论
常规胸部 CT 扫描对无症状患者潜在 COVID-19 变化的筛查没有益处。血液差异检测易于获得，因此在 COVID-19 筛查中更有帮助。
