Diagnostic efficacy of lung ultrasound and X-ray for neonatal respiratory distress syndrome and transient tachypnea / 中国医学影像技术

ABSTRACT

Objective To compare the efficacy of lung ultrasound and chest X-ray for diagnosis of neonatal transient respiration syndrome (TTN) and respiratory distress syndrome (RDS).Methods Totally 120 infants with respiratory distress underwent lung ultrasound and chest X-ray within 6 h after birth.Taking clinical diagnosis as the standard,the sensitivity,specificity and accuracy of lung ultrasound and X-ray for diagnosis of TTN and RDS were calculated.Results According to clinical diagnosis,there were 75 infants of TTN and 34 of RDS.The sensitivity,specificity and accuracy of lung ultrasound in diagnosis of TTN was 96.00％ (72/75),88.89％ (40/45) and 93.33％ (112/120),respectively,higher than those of chest X-ray (85.33％ [64/75],84.44％ [38/45] and 85.00％ [102/120]).Lung ultrasound showed 85.29％ (29/34) of sensitivity,95.35％ (82/86) of specificity and 92.50％ (111/120) of accuracy for diagnosis of RDS,whereas chest X-ray showed 88.23％ (30/34) of sensitivity,89.53％ (77/86) of specificity and 89.17％ (107/120) of accuracy.Conclusion Lung ultrasound is accurate for the diagnosis of TTN and RDS.
