摘要
目的探讨床旁经胸肺超声彗尾征诊断急性心源性呼吸困难的准确性。方法选择因急性呼吸困难入院的患者58例,于药物治疗前行床旁经胸肺超声检查。将患者分为心源性呼吸困难与肺源性呼吸困难,比较经胸肺超声检查结果,判断经胸肺超声彗尾征诊断心源性呼吸困难的敏感度、特异度及准确率。结果经胸肺超声彗尾征诊断急性心源性呼吸困难的敏感度为93.75%(30/32,95%CI 77.78%～98.91%),特异度为88.46%(23/26,95%CI 68.72%～96.97%),阳性预测值为90.90%(30/33,95%CI 74.53%～97.62%),阴性预测值为92.00%(23/25,95%CI 72.50%～98.60%),诊断准确率为91.38%(53/58)。结论根据经胸肺超声彗尾征可以较准确地诊断急性心源性呼吸困难。
Objective To evaluate the diagnostic accuracy of bed side transthoracic lung ultrasound comet-tail sign in dif- ferentiating heart failure （HF）-related acute dyspnea from pulmonary-related acute dyspnea. Methods Fifty-eight patients with acute dyspnea who underwent transthoracic lung ultrasound before pharmacotherapy were enrolled. The patients were divided into HF-related acute dyspnea group and pulmonary-related acute dyspnea group. The sensitivity, specificity, nega- tive predictive value （NPV）, positive predictive value （PPV） and accuracy of lung ultrasound in identifying the HF-related acute dyspnea were a,~sessed. Results Ultrasound comet-tail sign had a sensitivity of 93. 750//oo （30/32, 95%CI 77.78%-- 98.91%）, aspecificity of 88.46% （23/26, 95%CI 68.72%--96.97%）, PPV of 90.90%0 （30/33, 95%CI 74.53%-- 97.62%） and NPV of 92.00% （23/25, 95%CI 72.50%--98.60%） for the diagnosing HF-related acute dyspnea, and the accuracy was 91. 380/6 （53/58）. Conclusion Transthoracie ultrasound comet-tail sign has high diagnostic accuracy in dif- ferentiating acute HF-related from pulmonary-related acute dyspnea.
