Objective  To investigate the clinical value of pulmonary ultrasound in the exami-nation of atelectasis in neonates.

Methods  200 children with suspected neonatal atelectasis admitted to The First Affiliated Hospital of Henan University of Science and Technology from Semptember 2020 to December 2021 were selected as study subjects. All the children received chest X-ray and pulmonary ultrasound examination. The clinical diagnosis results were regarded as the gold standard, and the re-sults of different methods were analyzed and discussed.

Results  There was no statistical difference between two methods in the positive detection rate of focal atelectasis (P>0.05). In terms of the positive detection rate of latent atelectasis, the rate of pulmonary ultrasound was higher compared to the rate of chest X-ray  (92.3% vs. 53.85%, P=0.027). The diagnostic efficiency of pulmonary ultrasound was higher than that of chest X-ray (P<0.05). In addition, there was no statistical significance in treatment evaluation 5 days after treatment and before discharge (P>0.05).

Conclusion  Pulmonary ultrasound has good diagnostic efficacy for neonatal atelectasis and has a positive effect on the follow-up during treatment and pre discharge evaluation.
