Purpose or objective: To establish the findings of lung ultrasound (LUS) and the final outcome in patients with a diagnosis of COVID-19. Methods: This is a descriptive, prospective, longitudinal study. We studied all patients admitted to the health center who were diagnosed with COVID-19 and who underwent LUS. These 13 patients were evaluated by lung ultrasound and the US findings were associated with the final evolution of the patient. Results: 13 patients were evaluated, 8 (61.57%) men and 5 (38.46%) women, between 30 and 86 years old, with 1 to 4 follow up ultrasounds. 9 recovered and 4 died. A statistically significant relationship was demonstrated between: death as the final outcome and the presence of 11 or 12 affected areas of the 12 evaluated by LUS, regardless of the pathological pattern they presented (p <0.01). A statistically significant relationship was demonstrated between death as the final outcome of the patient and the presence of subpleural consolidations in at least 6 of the 12 areas evaluated by LUS during follow up (p <0.05). Conclusion: The presence of 11 or 12 areas affected by any pathological pattern on LUS and the presence of 6 or more areas with subpleural consolidations are ultrasound factors of poor prognosis in patients with COVID-19 disease. (p <0.01) and (p <0.05) respectively.
