摘　　要：目的研究肺脏超声对新生儿暂时性呼吸增快症（TTN）的诊断价值。方法2012年5月至12月在北京军区总医院附属八一儿童医院NICU住院，经临床表现、动脉血气分析和胸部X线检查确诊为TTN的40例患儿为研究组，同期住院的30例非肺病患儿为对照组。在安静状态下，患儿取仰卧、侧卧或俯卧位，以腋前线、腋中线、腋后线为界，将肺脏分为前、侧、后3个区域，探头与肋骨垂直或平行分别对双侧肺脏的每个区域进行扫查，并与传统胸部X线检查结果作对照。结果双肺点、肺泡-间质综合征或白肺、胸膜线异常、A-线消失、胸腔积液和彗星尾征等是TTN的常见超声声像图表现，无肺实变和支气管充气征。其中，双肺点对TTN诊断的敏感性和特异性均为100％。结论肺脏超声诊断TTN准确可靠，值得在新生儿监护病房内开展。Objective To evaluate the value of lung ultrasound to diagnose transient tachypnea of the newborn （TTN）. Methods From May to Dec. 2012,70 infants from NICU of Bayi Children＇s Hospital Affiliated to General Hospital of Beijing Military Command, were divided into 2 groups. The study group consisted of 40 newborn infants diag-nosed TTN by clinical manifestations, arterial blood-gas analysis and chest X-ray, while the control group consisted of 30 neonates without any lung diseases. In a quiet state, the infants were positioned in supine, side or prone. The lung field was divided into 3 areas by the anterior axillary line, midaxillary line and posterior axillary line. The regions of the bila- teral lung were scanned by the probe which was vertical or parallel with the ribs, then compared the results with conven-tional chest X-ray findings. Results The common ultrasound signs of TTN included double lung point, alveolar-intersti-tial syndrome or bilateral white lung, pleural line abnormalities, A-line disappearance, pleural effusion and comet-tail ar-tifacts, etc, without lung consolidation or air bronchogram. The double lung point was present in all infants with TTN, the sensitivity and specificity of which was all 100% for the diagnosis of TrN. Conclusion Lung ultrasonography is relia-ble for the diagnosis of TFN, and it is worth carrying out in NICU.
