摘　　要：目的:探究剪切波弹性成像(SWE)在新生儿呼吸窘迫综合征(NRDS)中的应用。方法:2019年1月-2020年5月收治NRDS患儿86例,作为研究组;另选取同时出生的正常新生儿86例,作为对照组。两组均进行肺脏SWE检查;比较两组超声图像特点及杨氏模量值。结果:对照组肺部呈低回声、胸膜线光滑、有A线,肺滑运动绝对而清晰,无胸腔积液及肺泡-间质综合征(AIS);研究组肺部呈高回声,胸膜线消失或呈增厚、模糊状态,A线消失,肺滑不明显,有AIS。研究组平均(Mean)值、最小(Min)值、最大(Max)值均高于对照组,差异有统计学意义(P<0.05)。对照组住院第1天、第3天、第7天Mean值比较,差异无统计学意义(P>0.05);研究组Mean值显著下降,但仍高于对照组,差异有统计学意义(P<0.05)。结论:SWE在NRDS中具有较高诊断价值,同时还可应用于临床疗效的评价。Objective:To explore the application of shear wave elasticity imaging(SWE)in neonatal respiratory distress syndrome(NRDS).Methods:From January 2019 to May 2020,86 children with NRDS were selected as the study group.Another 86 normal newborns were selected as the control group.Lung SWE was performed in both groups.We compared the ultrasonic image characteristics and Young's modulus between the two groups.Results:In the control group,the lung showed hypoechoic,smooth pleural line,A-line,absolute and clear pulmonary sliding motion,and there was no pleural effusion and alveolar interstitial syndrome(AIS).In the study group,the lung was hyperechoic,pleural line disappeared or thickened,fuzzy state,A line disappeared,lung slip was not obvious,and there was AIS.In the study group,Mean value,Min value and Max value were higher than those in the control group,the difference was statistically significant(P<0.05).In the control group,there was no significant difference in Mean value on the first day,the third day and the seventh day of hospitalization(P>0.05).In the study group,Mean value decreased significantly,but it was still higher than that in the control group,the difference was statistically significant(P<0.05).Conclusion:SWE has high diagnostic value in NRDS,and can also be used in the evaluation of clinical efficacy.
