COVID-19 pneumonia is responsible for the latest pandemic. Usage of pulmonary computed tomography (CT) scan is known to be an important method in the diagnosis of COVID-19. Here, we aimed to evaluate the relationship between CT severity score and capillary blood oxygen saturation in patients with COVID-19 infection. This is a cross-sectional study performed in 2020 on patients with COVID-19 infection. All patients underwent pulmonary CT scan and CT severity score was calculated. The initial capillary oxygen saturation by the time of admission was also collected. Data were collected and analyzed. A total number of 270 patients diagnosed with COVID-19 infection entered the study. The initial mean capillary oxygen saturation was 89.65 ± 8.09%. The mean score in patients was 15.16 ± 8.08. We also indicated that 27 patients had hypoxia by the time of admission and these patients had significantly higher CT severity scores ( = 0.001). Diabetes mellitus ( = 0.001), hypertension ( = 0.001), and chronic obstructive pulmonary disease (COPD) ( = 0.03) and totally having an underlying disease ( < 0.001) were significantly associated with decreased capillary oxygen saturation. Patients with hypertension ( = 0.001) and patients with the previous medical disease ( = 0.01) had significantly higher CT severity scores than others. There was a significant reverse relationship between CT severity score and capillary oxygen saturation ( = -0.44, < 0.001). We showed that there was a significant reverse relationship between CT severity score and capillary oxygen saturation which has great clinical importance. Furthermore, we indicated that previous medical history could also play an important role in CT severity score. Aalinezhad M, Alikhani F, Akbari P, Haji Rezaei M, Soleimani S, Hakamifard A.

新型冠状病毒肺炎（COVID-19）引发了最近的这场大流行。肺部计算机断层扫描（CT）已被确认为诊断COVID-19的重要手段。在此，我们旨在评估COVID-19感染患者的CT严重程度评分与毛细血管血氧饱和度之间的关系。这是一项于2020年针对COVID-19感染患者开展的横断面研究。所有患者均接受了肺部CT扫描，并计算了CT严重程度评分。同时收集了入院时的初始毛细血管血氧饱和度。对数据进行了收集与分析。共有270例确诊为COVID-19感染的患者纳入本研究。初始平均毛细血管血氧饱和度为89.65±8.09%。患者的平均评分为15.16±8.08。我们还指出，27例患者在入院时存在低氧血症，这些患者的CT严重程度评分显著更高（P = 0.001）。糖尿病（P = 0.001）、高血压（P = 0.001）、慢性阻塞性肺疾病（COPD）（P = 0.03）以及患有基础疾病（P < 0.001）均与毛细血管血氧饱和度降低显著相关。高血压患者（P = 0.001）以及有既往病史的患者（P = 0.01）的CT严重程度评分显著高于其他患者。CT严重程度评分与毛细血管血氧饱和度之间存在显著的负相关关系（r = -0.44，P < 0.001）。我们发现CT严重程度评分与毛细血管血氧饱和度之间存在显著的负相关关系，这具有重要的临床意义。此外，我们指出既往病史在CT严重程度评分中也可能起到重要作用。Aalinezhad M、Alikhani F、Akbari P、Haji Rezaei M、Soleimani S、Hakamifard A。COVID-19感染患者CT严重程度评分与毛细血管血氧饱和度之间的关系。《印度重症监护医学杂志》2021年；25(3):279 - 283。
