| 摘要: |
| 目的：肺间质性病变患者肺超声出现特征性的垂直于胸膜强回声线的“彗星尾”伪像,称为B线。本研究应用床边肺超声观察急性心源性肺水肿患者肺超声B线特征及其变化,探讨B线在临床病变程度判断及治疗效果评价中的价值。方法：19例急诊入院确诊为急性心源性肺水肿患者,均行床边肺部12区超声检查(左肺6区,右肺6区),B线出现频率(出现B线的肺扫描区个数)分别与动脉血氧分压(PaO2),血中脑利钠肽(BNP)水平行相关分析。治疗两周后重复肺超声检查,比较治疗前后B线出现频率。结果：所有患者均可观察到两肺弥漫性B线,出现频率与血浆BNP水平呈正相关(r＝0.65),和PaO2呈负相关(r＝-0.73)。治疗两周后B线出现频率较治疗前明显减低(2.1±1.1 vs 7.3±2.4,p<0.01)。结论：床边肺超声B线可作为有效评估急性心源性肺水肿病变程度及随访治疗效果的简便手段。 |

| Abstract: |
| Objective: Vertical lines arising from the pleural line, the comet-tail artifact, referred as B line, is a characteristic image in patients with interstitial lesions. Our aim is to observe B lines using bedside lung ultrasound examination in patients with acute cardiogenic pulmonary edema, assess its value in monitoring the severity and resolution of pulmonary edema. |
