To investigate the correlation between capillary blood oxygen saturation and computerised tomography severity index in patients with coronavirus disease-2019 pneumonia.
The cross-sectional analytical study was conducted at the coronavirus disease-2019 ward of Nishtar Medical University and Hospital, Multan, Pakistan, June 1, 2020, to June 1, 2021. At the time of admission, capillary oxygen saturation of all patients was measured. Pulmonary computerised tomography scans were then performed, and computerised tomography severity index was calculated. Data was analysed using SPSS 18.
Of the 170 patients, 90 (52.9%) were males and 80(47%) were females. The overall mean age of the sample was 56.32±12.45 years. At the time of admission, the mean oxygen saturation was 88.9±6.53% and the mean severity index was 15.01±7.79. Overall, 22(12.9%) patients had hypoxia and the severity index reading was significantly high in these patients (p=0.001). Chronic obstructive pulmonary disease, hypertension and diabetes were significantly related to reduced blood oxygen saturation (p<0.05). Patients with hypertension had significantly raised computerised tomography scores. A significant inverse correlation was found between capillary oxygen saturation and computerised tomography severity index (p<0.01).
A significant inverse correlation was found between capillary oxygen saturation and computerised tomography severity index. Underlying comorbidities also affected the severity index.
研究 2019 冠状病毒病肺炎患者毛细血管血氧饱和度与计算机断层扫描严重指数的相关性。
本横断面分析研究于 2020 年 6 月 1 日至 2021 年 6 月 1 日在巴基斯坦木尔坦尼什塔尔医科大学和医院的 2019 冠状病毒病病房进行。所有患者入院时均测量毛细血管血氧饱和度，然后进行肺部计算机断层扫描，并计算计算机断层扫描严重指数。使用 SPSS 18 进行数据分析。
在 170 名患者中，90 名（52.9%）为男性，80 名（47%）为女性。样本的总体平均年龄为 56.32±12.45 岁。入院时，平均血氧饱和度为 88.9±6.53%，平均严重指数为 15.01±7.79。总体而言，22 名（12.9%）患者存在缺氧，这些患者的严重指数读数明显较高（p=0.001）。慢性阻塞性肺疾病、高血压和糖尿病与血氧饱和度降低显著相关（p<0.05）。高血压患者的计算机断层扫描评分明显升高。毛细血管血氧饱和度与计算机断层扫描严重指数之间存在显著负相关（p<0.01）。
毛细血管血氧饱和度与计算机断层扫描严重指数之间存在显著负相关。潜在的合并症也会影响严重指数。
