Abstract: This paper discussed the value of bedside lung ultrasound score in the diagnosis and treatment of premature infants with respiratory distress syndrome. 88 premature infants with respiratory distress syndrome treated were selected as the observation group, and 100 premature infants without respiratory distress syndrome were selected as the control group. Compared the differences of bedside lung ultrasound score (LUS) between the two groups, and each different clinical data in the observation group, further analyzed the value of LUS score in predicting respiratory distress syndrome complicated with bronchopulmonary dysplasia and extremely critical respiratory distress syndrome. The LUS scores of bilateral lung, left lung and right lung in the observation group were significantly higher than those in the control group (P<0.05). In the observation group, the lung LUS scores of children with bronchopulmonary dysplasia, respiratory distress score > 8, and extremely critical disease (neonatal critical case score <70) were significantly higher than those of other children (P<0.05). Bilateral lung LUS score was positively correlated with respiratory distress score (P<0.05), and negatively correlated with neonatal critical case score (P<0.05). Bedside high frequency ultrasound monitoring has certain application value in the diagnosis and treatment of premature infants with respiratory distress syndrome complicated with bronchopulmonary dysplasia and disease degree.
