Abstract
Background Sudden exacerbations and respiratory failure are major causes for the death of severe COVID-19 pneumonia patient and but now the detection and treatment of severe patients is still lack. Methods A retrospective analysis is conducted on 69 collected cases, which are about 69 patients with COVID-19 pneumonia who were admitted to the Suzhou Fifth People’s Hospital from January 1, 2020 to February 8, 2020. Their epidemiological, clinical and imaging characteristics as well as laboratory data of the 69 patients were analyzed. Results The study found fibrinogen increased in 45 (65.2%) patients and when the fibrinogen takes a critical value of 4.805 g/L, the sensitivity and specificity, helping distinguish general and severe classification, are 100% and 14%, respectively, which are significantly better than lymphocyte and myoglobin. Chest CT images indicate that the cumulative number of lung lobes in severe patients were significantly higher than that in general patients (P<0.05) and the cumulative number of lung lobes in the lesions was negatively correlated with lymphocyte, and positively correlated with myoglobin and fibrinogen. Our study also found that there is no obvious effect of hormone therapy in severe patients with COVID-19. Conclusions Based on the retrospective analysis, the fibrinogen were found increased in severe patients and were better than lymphocyte and myoglobin in respect of distinguishing general and severe patients. And the study also suggested hormone treatment has no significant effect on COVID-19.
