The Clinical Application Of 12 Partition Of Lung Ultrasound Score In Neonatal Respiratory Distress Syndrome

BackgroundNeonatal respiratory distress syndrome(NRDS)is a common critical disease in neonates,especially in premature infants.Early diagnosis and treatment can improve the prognosis of children.For a long time,the imaging examination of NRDS children's condition evaluation mainly depends on the bedside X-ray classification,but the X-ray examination has certain radiation risk,and the repeated radiography is considered to have the nature of accumulation,and once thought to have the carcinogenic effect,the newborn is more sensitive to it [1].In recent years,lung ultrasound has become a research hotspot.But whether pulmonary ultrasound can predict the severity of neonatal respiratory distress syndrome is unclear.So this topic is to study this problem.ObjectiveTo evaluate the clinical application value of lung 12 area ultrasound score in evaluating the severity of NRDS.At the same time,we analyzed the correlation between the 12 zone lung ultrasound score and the traditional parameters,such as oxygenation index,neonatal respiratory distress score and neonatal critical illness score.MethodsThe selected cases were 77 children who were admitted to the First Affiliated Hospital of Xinxiang Medical College within 24 hours from October 2018 to January 2020 due to NRDS.All the children in the group were given 12 zone ultrasound score of lung.Spearman analysis was used to analyze the correlation between 12 zone ultrasound score of lung and X-ray grade.Meanwhile,the differences of ultrasound scores between grade I,grade II,grade III and grade IV were compared.ROC curve was used to predict the cutoff value,sensitivity and specificity of ultrasound corresponding to X-ray of NRDS children.Pearson analysis was used to analyze the correlation between pulmonary ultrasound score and oxygenation index,neonatal respiratory distress score,neonatal critical illness score(NCIS).Result1.There was a positive correlation between the 12 area ultrasound score and chest X-ray grading(r = 0.742,P < 0.05).There was a significant difference in the ultrasound scores of chest X-ray grades I,II,III and IV(P < 0.05).The cutoff points of grade I and grade II were 14.5,AUC 0.882,sensitivity 94.6%,specificity 71.4%,P = 0.000.Grade II and grade III cutoff points were 23,AUC was 0.875,sensitivity was 81.8%,specificity was75.7%,P = 0.001.The cutoff points of grade III and IV were 29.5,AUC was 0.858,sensitivity was 85.8%,specificity was 81.8%,P = 0.009.2.There was a negative correlation between the 12 area ultrasound score and 0I(r =-0.827,P < 0.05).3.There was a negative correlation between the 12 area ultrasound score and NCIS(r=-0.799,P < 0.05).4.There was a positive correlation between the 12 area ultrasound score and the score of respiratory distress(r = 0.917,P< 0.05).ConclusionThe lung 12 area ultrasound score can predict the severity of NRDS.The higher the score,the more serious the disease.It can also be graded like an X-ray.
