Abstract
OBJECTIVES: To investigate the diagnostic effect of lung ultrasound on neonatal respiratory distress syndrome (NRDS) and to analyze the clinical application value of pulmonary ultrasound score. METHODS: Sixty-five NRDS babies who were diagnosed in our hospital from August 2019 to October 2020 were selected as the observation group, and 65 healthy babies were selected as the control group. Children in the two groups underwent lung ultrasound examination. The characteristic signs of lung ultrasound in the two groups were analyzed, and the detection rate of various signs and lung ultrasound score were compared between the two groups. RESULTS: The main manifestations of lung ultrasound in NRDS children were pulmonary parenchyma, abnormal pleural line, blurred or disappeared A line, pleural effusion, white lung, and weak or disappeared pulmonary pulsation; the lung ultrasound scores of different positions in the observation group were higher than those in the control group, and the differences were statistically significant (P<0.05). The detection rates of signs such as lung parenchyma, abnormal pleural line, disappeared A line, diffuse pulmonary edema, and air bronchogram in the observation group were significantly higher than that in the control group (P<0.05), and there was no significant difference in the detection rate of the sign of B line existence between the two groups (P>0.05). CONCLUSION: Lung ultrasound has a high diagnostic value in diagnosing NRDS, and lung ultrasound score can evaluate the severity of NRDS in babies to further optimize the diagnosis results, which has important clinical significance.
