【 摘 要 】

Introduction . One of the ultrasonic features of COVID-19 pneumonia is the presence of subpleural consolidation (SPC), and the number of SPCs varies among patients with COVID-19 pneumonia. Aim . To examine the relationship between disease severity and the number of SPCs on admission. Methodology . This observational, prospective, single‐center study included patients with suspected COVID-19 infection who had been transferred to the ICU. A specialized intensivist in critical care ultrasound performed lung ultrasound (LUS) and echocardiography within 12 hours of a patient’s admission to the ICU. The aeration score was calculated, and the total number of SPCs was quantified in 12 zones of the LUS. Results . Of 109 patients with suspected COVID-19 pneumonia, 77 (71%) were confirmed. The median patient age was 53 (82–36) years, and 81 of the patients (73.7%) were men. The aeration score and the counts of subpleural consolidation in each zone were significantly higher in patients with COVID-19 pneumonia ( and , respectively). There was an inverse relationship between PO 2 /FiO 2 , the aeration score, and the number of subpleural consolidations. The higher the number of SPCs, the worse the PO 2 /FiO 2 will be. Conclusions . Sonographic SPC counts correlate well with the severity of COVID-19 pneumonia and PO 2 /FiO 2 . The number of SPCs should be considered when using LUS to assess disease severity.
