Objective: To investigate the application of remote ultrasound in COVID-19 isolation ward.
Methods: Two patients with suspected COVID-19 were admitted to the isolation ward in critical condition. In the isolation ward, the intensive care unit (ICU) physician used ultrasound to evaluate patients’ heart, lung, abdomen, blood volume, and lower limb veins, guided by an ultrasound expert in remote.
Results: (1) Under the guidance of the ultrasound expert, the ICU physician successfully performed ultrasound examination and gathered clear images. (2) The main manifestations of the patients’ lung lesions were multiple B3-lines in both lungs fused to “white lung” and pulmonary consolidation in the subpleural area. A small amount of effusion was observed in the bilateral costal diaphragmatic angle and left lower extremity vein thrombosis was found in patient No.1. Ultrasound was also used to assess the inner diameter and respiratory variability of the inferior vena cava for adjusting fluid supplementation. Patient No.1’s condition was severe with rapidly progressing pulmonary lesions. After treatment, ultrasound showed improvement in pneumonia and disappearance of pleural effusion and the left lower extremity vein thrombosis. (3) There was a high degree of consistency between ultrasound and chest computerized tomography (CT) findings in two patients.
Conclusion: The application of remote ultrasound can reduce the risk of cross-infection and save the personal protective equipment in the COVID-19 outbreak. Ultrasound experts can also provide real-time guidance for ICU physician to maintain a good quality of patient care and receive high-quality images for accurate diagnosis.
