Abstract:
Purpose To investigate the diagnostic significance of modified lung ultrasound score(MPUS)for pediatric bacterial and viral pneumonia.Materials and Methods A total of 93 eligible children with suspected community-acquired pneumonia in Quanzhou Maternal and Child Care Hospital(Quanzhou Children’s Hospital)from December 2022 to June 2023 were elected as the study subjects.All these children received lung ultrasound and the MLUS was recorded according to the ultrasound manifestations of A line,B line and lung consolidation.According to the etiological results,the children were divided into a bacterial pneumonia group and a viral pneumonia group.According to disease severity,the children were divided into the mild group and the severe group.The MLUS was used to analyze the diagnostic significance of pediatric bacterial and viral pneumonia.Results The MLUS in the mild pneumonia group was 7(4,13)points and the MLUS in the severe pneumonia group was 20(14,30)points,and MLUS scores of pneumonia in the two groups were different(Z=-5.205,P<0.05).By drawing receiver operating characteristic curve,MLUS score of 14.5 was used as the cut-off point,the sensitivity for diagnosing severe pneumonia was 75.9%,the specificity was 82.8%.Area under the curve was 0.838.There was no significant differences in MLUS of 8.00(4.00,16.00)between the bacterial pneumonia group and 13.00(7.00,21.75)between the viral pneumonia group(Z=-1.981,P>0.05).The MLUS of 10.00(5.25,17.75)in the mild bacterial pneumonia group and 5.00(4.00,9.50)in the mild viral pneumonia group were significantly different(Z=-3.403,P<0.05).There was no significant differences in MLUS between the severe bacterial pneumonia group and the severe viral pneumonia group(t=0.017,P>0.05).In mild pneumonia,the cut-off value for the modified lung ultrasound score of 10.5 predicted moderate diagnostic efficacy of mild bacterial pneumonia,the area under the curve was 0.747,sensitivity was 50%and specificity was 87.5%.Large-area lung consolidation was more common in the bacterial pneumonia group than in the viral pneumonia group(χ2=8.360,P<0.05).Conclusion The modified lung ultrasound score can effectively evaluate the severity of pediatric bacterial pneumonia and viral pneumonia.For the identification of the two,MLUS may be a certain guiding significance.
