Abstract:
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.
