Abstract Objective To evaluate the value of simplified lung ultrasound score (LUS) in dynamic assessment of lung injury in critically ill patients. Methods Sixty-four patients admitted to the emergency intensive care unit (EICU) of the Second Affiliated Hospital of Zhejiang University Medical College were prospectively observed from July 2017 to September. LUS in 12 regions was evaluated by ultrasound. LUS were recorded before and after treatment. The oxygenation index (PaO2/FiO2, PF), ICU hospitalization time and so on were recorded. Based on the 12 regions LUS, a variety of simplified LUS methods were established to observe the correlation with the12 regions LUS. Results The correlation between the 4 regions and the 12 regions was high before and after the treatment of 64 patients (P<0.05). In the survival group, the simplified 4 regions before treatment and after treatment had a high correlation with the 12 regions (P<0.05). The simplified 4 regions LUS was improved after treatment (4.75±2.36 vs. 3.11±0.95, P<0.05). PF was improved after treatment (287.32±74.89 vs.355.12±61.07,P<0.05). In death group, there was a good correlation between LUS and PF before and after treatment (P<0.05). Before and after treatment, the simplified 4 regions were highly correlated with the 12 regions in the death group (P<0.05). LUS deterioration in simplified 4 regions. Before treatment (5.71±1.79) compared with after treatment (8.71±1.49) (P<0.05). PF deteriorated. Before treatment (206.57±69.72) compared with after treatment (117.42±28.56) (P<0.05). There was no correlation between LUS and PF before and after treatment (P>0.05). The LUS and PF of the simplified 4 regions were improved in nine patients before and after extubation (P<0.05). Conclusion The simplified 4 regions LUS has a high correlation with the 12 regions LUS, which also reflects the degree of lung injury in critically ill patients and is worthy of clinical application as a means of monitoring.
