超声与X线胸片对新生儿暂时性呼吸增快症和呼吸窘迫综合征的诊断效能

Diagnostic efficacy of lung ultrasound and X-ray for neonatal respiratory distress syndrome and transient tachypnea

目的比较肺脏超声与X线胸片对新生儿暂时性呼吸增快症(TTN)和呼吸窘迫综合征(RDS)的诊断效能。方法对120例呼吸困难新生儿于出生后6h内行肺脏超声和X线胸片检查,以临床诊断为标准,计算两种检查方法诊断TTN和RDS的敏感度、特异度和准确率。结果临床诊断75例TTN和34例RDS,肺脏超声诊断TTN的敏感度、特异度和准确率分别为96.00%(72/75)、88.89%(40/45)和93.33%(112/120),均高于X线胸片[分别为85.33%(64/75)、84.44%(38/45)和85.00%(102/120)]。肺脏超声诊断RDS的敏感度为85.29%(29/34),特异度为95.35%(82/86),准确率为92.50%,(111/120),而X线胸片诊断RDS的敏感度为88.23%(30/34),特异度为89.53%(77/86),准确率为89.17%(107/120)。结论肺脏超声可准确诊断新生儿TTN和RDS。

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 hafter 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 showed85.29%（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.
