Diagnosis of pulmonary hemorrhage of the newborn infants using lung ultrasonography / 中华儿科杂志

ABSTRACT

Objective@#To investigate the accuracy and reliability of lung ultrasound in diagnosis of pulmonary hemorrhage of the newborn infants.@*Method@#From January 2014 to May 2016, 142 neonates from the Army General Hospital of the Chinese PLA were enrolled in the study. They were divided into two groups a study group of 42 neonates, who were diagnosed with pulmonary hemorrhage according to their medical history, clinical manifestations and chest X-ray findings, and a control group of 100 neonates with no lung disease. All subjects underwent bedside lung ultrasound in a quiet state in a supine, lateral or prone posture, performed by a single experienced physician. The ultrasound findings were compared between the two groups.Fisher′s exact test was uesd for comparison between two groups.@*Result@#The lung ultrasound main findings associated with pulmonary hemorrhage included (1) Shred sign which was seen in 40 patients(95%). (2) Lung consolidation with air bronchograms which were seen in 35 patients(83%). (3) Pleural effusion which was seen in 34 infants(81%), pleurocentesis confirmed that the fluid was really bleeding.(4)Atelectasis which was seen in 14 cases(33%). (5) Pleural line abnormalities and disappearing A-lines with an incidence of 100%. (6) Alveolar-interstitial syndrome 5 patients(12%)had the main manifestations of alveolar-interstitial syndrome. The above signs were not seen in normal controls (all P<0.01) and the normal lung mainly manifested with clear pleural line and A-lines under ultrasound.@*Conclusion@#Lung ultrasonography is accurate and reliable for diagnosing pulmonary hemorrhage, which is suitable for routine application for the diagnosis of pulmonary hemorrhage in the neonatal intensive care unit.
