COMPARISON OF LUNG ULTRASOUND AND RADIOGRAPH IN THE DIAGNOSTIC VALUE OF NEONATAL RESPIRATORY DISTRESS SYNDROME

Abstract

TYPE: Abstract TOPIC: Pediatrics PURPOSE: To compare the reliability and accuracy of lung ultrasound (LUS) and chest X-ray(CXR) in the diagnosis of neonatal respiratory distress syndrome (RDS). METHODS: A retrospective analysis of 117 infants with RDS.Subjects met the following criteria :(1) Clinical diagnosis of RDS.(2) LUS and CXR were performed simultaneously. RESULTS: (1) Among the 117 cases, 111 cases were diagnosed with RDS by LUS, with a diagnostic coincidence rate of 95%; while only 57 cases were diagnosed by CXR with a coincidence rate was 48.7%.There was statistically significant difference between two methods (χ2=61.54, P < 0.05). In the diagnosis of RDS complications 1 pneumothorax was found by LUS as well as CXR, 47 cases of pneumonia were diagnosed by LUS and 19 of them were diagnosed by CXR, 5 cases of pleural effusion were found by LUS and only 1 case was found by CXR.The detection rate of RDS complications was 45.3% by LUS and only 18.0% by CXR(χ2=20.24, P < 0.05). Lung consolidation with air bronchograms, disappearance of A-line and abnormal pleural line are the main ultrasonic signs of RDS. CONCLUSIONS: LUS to diagnose RDS is accurate and reliable, and it is better to find the complications than CXR. CLINICAL IMPLICATIONS: Because it is no radiation damage, easy and convenient for dynamic observation at the bedside, thus it is suitable for clinical application in neonatal wards.
