The yield of lung ultrasound in neonates with respiratory distress

Abstract

Background: A systematic ultrasound has been validated across a wide span of ages using both chest anatomic structures (ie, ribs , pleural line)and artifact images ,such as the B-lines. Multiple diffuse bilateral B-lines are suggestive of interstitial syndrome . In the neonate, one can accurately differentiate the aerated dry lung, appearing as uniform hypoechogenic pattern, sliding with respiration and showing horizontal (the A-lines) ,from the hyperechogenic “white” pattern of the markedly “wet” or inflamed organ. Objective To study the value of chest ultrasound in neonates with RD And its value in comparison with chest x –rays.Methods: This prospective hospital based study was conducted on 74 neonates (October 2017to September 2018 in the Neonatal intensive care unit at Sohag university hospital with any degree of RD .All cases was involved with physical examination, chest x-ray and chest US. finally data was analyzed by SPSS software.Results: In the all the 74 cases chest ultrasound was applied and the disease was further categorized into RDS 25 cases (33.78%) .Pneumonia13 cases (17.56%), (TTN) 25 cases (33.7%) , (MAS), 9cases(12.16%).Pleural effusion4 cases (5.40%). We found that there no difference between diagnosis of the cases by(clinically ,history , and chest x-rays ) versus chest sonar diagnosis (p value=0.157) which was statistically in significant . Conclusion: no difference between diagnosis of the cases by(clinically ,history , and chest x-rays ) versus chest US diagnosis.Study Limitation:: we conduct only the neonatal group suffered from limited disease as RDS,TTN,MAS ,Pneumonia, excluding cases with congenital malformation .
