OBJECTIVES
To assess the potential of bedside lung ultrasound to diagnose the radiologic alveolar-interstitial syndrome (AIS) in patients admitted to an emergency medicine unit and to estimate the occurrence of ultrasound pattern of diffuse and multiple comet tail artifacts in diseases involving lung interstitium.
METHODS
The ultrasonic feature of multiple and diffuse comet tail artifacts B line was investigated in each of 300 consecutive patients within 48 hours after admission to our emergency medicine unit. Sonographic examination was performed at bedside in a supine position. Eight anterolateral ultrasound chest intercostal scans were obtained for each patient.
RESULTS
The artifact showed a sensitivity of 85.7% and a specificity of 97.7% in recognition of radiologic AIS. Corresponding figures in the identification of a disease involving lung interstitium were 85.3% and 96.8%.
CONCLUSION
Comet tail artifact B line is a lung ultrasound sign reasonably accurate for diagnosing AIS at bedside.
目的
评估床旁肺部超声诊断急诊医学科收治患者的放射学肺泡间质综合征（AIS）的潜力，并估计在涉及肺间质的疾病中弥漫性和多发性彗尾伪像超声模式的发生率。
方法
在我院急诊医学科收治的300例连续患者入院后48小时内，对其多发性和弥漫性彗尾伪像B线的超声特征进行研究。在患者仰卧位时于床旁进行超声检查。每位患者获取8次前外侧胸部肋间超声扫描图像。
结果
该伪像在识别放射学AIS方面的敏感性为85.7%，特异性为97.7%。在识别涉及肺间质的疾病方面，相应的数据分别为85.3%和96.8%。
结论
彗尾伪像B线是一种在床旁诊断AIS相当准确的肺部超声征象。
