The Evaluation Value of Pulmonary Ultrasound Examination on the Severity and Prognosis of Pul-monary Infection Patients
[Objective]To explore the evaluation value of pulmonary ultrasound examination on the severity and prognosis of pulmonary infection patients.[Method]A total of 100 patients with pulmonary infections admitted to Meng-zhou Fuxing Hospital and the Second Affiliated Hospital of Zhengzhou University in Henan Province from January 2020 to December 2022 were selected as the infection group.In addition,100 volunteers who did not have pulmonary infections during physical examinations were selected as the control group.Both groups underwent pulmonary ultrasound examina-tion,and the pulmonary ultrasound characteristics and pulmonary ultrasound scores(LUS)of the two groups were com-pared.Simple linear correlation was used to analyze the correlation between LUS and the acute physiological function and chronic health scoring system(APACHE Ⅱ)score,clinical pulmonary infection score(CPIS),peripheral blood white blood cell(WBC)count,serum prealbumin(SPA),and soluble myeloid trigger receptor-1(STREM-1)in patients with pulmonary infection.The predictive value of LUS for the prognosis of patients with pulmonary infection was analyzed.[Result]The detection rate of B-line sign,lung consolidation sign,lung sliding sign weakened or disappeared,and air bronchial inflation sign in the infected group was higher than that in the control group,and the difference was statistically significant(P＜0.05);The WBC count,serum STREM-1 level,and LUS in the infected group were significantly higher than those in the control group(P＜0.05),while the serum SPA level was significantly lower than that in the control group(P＜0.05).There was a significant positive correlation between WBC count,serum STREM-1 level,APACHE Ⅱscore,CPIS,and LUS in the infected group(P＜0.05);The serum SPA level in the infected group was significantly negatively correlated with LUS(P＜0.05).After treatment,17 out of 100 patients died and 83 improved and were dis-charged.The analysis of Receiver Operating Characteristic(ROC)curves showed that LUS had a sensitivity of 71.04％,specificity of 87.34％,and an area under the ROC curve of 0.884 for predicting mortality in patients with pulmonary in-fections.[Conclusion]LUS is significantly correlated with the levels of inflammatory factors and the severity of pulmonary infection in patients,and can be used to predict patient prognosis.
