| 目的 探讨肺超声评分（LUS）定量评估新生儿呼吸窘迫综合征（NRDS）严重程度及其临床意义。方法 收集74例NRDS患儿与30名对照组新生儿。对比LUS与X线检查、呼吸机辅助通气情况、呼吸机参数等临床资料。分析LUS与X线分级、辅助通气情况及呼吸机参数的相关性；应用ROC曲线评价LUS预测NRDS临床严重程度及需有创呼吸机辅助治疗的价值。结果 NRDS的肺超声表现为弥漫分布密集B线、A线消失、胸膜线异常、肺滑动征减弱、肺实变。NRDS患儿的LUS与X线分级、临床分度、辅助通气模式分级、呼吸机使用天数、呼吸机参数等呈正相关（P均<0.05）。LUS预测轻、中、重度NRDS的分值分别为13.0、22.5、29.5分。以LUS为22.5分预测患儿需应用有创辅助通气的敏感度和特异度分别为86.0%和64.5%。结论 LUS可以诊断并定量评估NRDS病情的严重程度，以指导临床诊疗。 |

| Objective To evaluate the value of lung ultrasound score (LUS) in the quantitative assessment of the severity of neonatal respiratory distress syndrome (NRDS) and the value of clinical diagnosis and treatment.Methods Totally 74 NRDS cases and 30 normal neonates were studied.LUS was compared with X-ray examination,clinical data,ventilator assisted ventilation and ventilator parameters.ROC curve was used to calculate sensitivity and specificity of LUS to predict the severity of NRDS and application of invasive ventilator treatment.Results The main findings of the lung ultrasound in NRDS included diffuse distribution of dense B line,disappeared A line,pleural line abnormalities,decreased pulmonary slip sign and pulmonary consolidation.LUS in patients with NRDS was significantly correlated with X-ray grades,clinical grades,assisted ventilation mode grades,number of days on ventilator and ventilator parameters (all P<0.05).LUS value to predict mild,moderate and severe NRDS were 13.0,22.5,and 29.5,respectively.The best cutoff point for LUS to predict the adoptation of invasive assisted ventilation was 22.5,which had sensitivity of 86.0% and specificity of 64.5%.Conclusion LUS can be used to diagnose and evaluate the severity of the desease,and to guide the clinical diagnosis and treatment. |
