CHEST X-RAY MANIFESTATIONS OF DECEASED COVID-19 PATIENTS IN THE EMERGENCY DEPARTMENT AT CHO RAY HOSPITAL
Main Article Content
Abstract
Background: COVID-19 is a global pandemic with a very high mortality. Patients are hospitalized with rapid disease progression and early deadth in the Emergency Department. Chest X-ray play an important role in diagnosis and prognosis of mortality. Purpose: (1) describe the chest X-ray findings of deceased covid-19 patients; (2) evaluate the relationship between Brixia score to mortality of COVID-19 patients in the Emergency Department. Methods: Retrospective study of COVID-19 patients who died at the Emergency Department, Cho Ray Hospital from August 1, 2021 to August 31, 2021, diagnosed with COVID-19 by RT-PCR technique. Clinical features and radiographic features were collected. Results: There are 226 cases in our study. We found that almost lesions distributed on bilateral lung (99%), in all 6 lung regions (78.3%) and diffuse distribution (94,2%). Interstitial, alveolar and consolidation lesions accounted for 69.5%, 61.9% and 94.7%, respectively. Pleural effusion occurs in 10.9% of cases. Pneumothorax and pneumomediastinum accounted for only 0.9% and 1.3% of cases. The mean Brixia score was 15. The mild, moderate and severe subgroups of the Brixia score were 6 (2.7%), 31 (13.8%) and 188 (83.5%) cases, respectively. There is a relationship between Brixia score and gender. Conclusions: Characteristics of chest X-ray in deceased COVID-19 patients mostly had consolidation, multifocal, many lung fields involved and diffuse distribution in both lungs. Other features such as pleural effusion, pneumothorax, subcutaneous emphysema and pleural thickening can be observed. Most of the patients who died had high Brixia scores.
