Lung ultrasound B-lines are the sonographic pattern of partial deaeration of the lung. In patients with pulmonary edema they are detected as multiple, diffuse, and bilateral, by placing the ultrasound probe in the intercostal spaces. B-lines can be used for bedside monitoring of pulmonary decongestion, and can guide diuretic therapy. Persistent pulmonary congestion after hospitalization for acute heart failure increases the risk of being rehospitalized in the following months. Adding B-lines assessment to echocardiography in an integrated cardiopulmonary ultrasound is of great value in establishing the kind and degree of myocardial and valvular impairment, and their hemodynamic consequences as pulmonary edema.
肺部超声 B 线是肺部部分去气的超声表现。在肺水肿患者中,通过将超声探头放置在肋间隙中,可以检测到多个、弥漫性和双侧的 B 线。B 线可用于床边监测肺部充血情况,并指导利尿剂治疗。急性心力衰竭住院后持续存在肺部充血会增加随后几个月再次住院的风险。在综合心肺超声中,将 B 线评估与超声心动图相结合,对于确定心肌和瓣膜损伤的类型和程度及其作为肺水肿的血流动力学后果具有重要价值。
