不同类别肺水肿在肺部超声中B线的对比

Compared of Different Categories of Pulmonary Edema in the Lung Ultrasound B Line

目的探讨不同类别肺水肿,特别是心力衰竭肺水肿与肺源性肺水肿,通过肺部超声中B线的数量进行对比,有助于协助肺水肿的临床判断。方法本次共纳入20例心力衰竭肺水肿患者,及25例炎症性肺水肿患者,采集315组数据,对比两种病理条件下患者的肺脏不同检查部位B线数目和EVLWI的差异。结果炎症性肺水肿出现B线的相关性(R^2=0.7178,P<0.01)较心力衰竭肺水肿(R^2=0.02,P<0.01)高,而两种病理情况下,肺脏各部位B线数目、EVLWI的数值无明显差异(P>0.05)。结论炎症性肺水肿的患者对比心力衰竭肺水肿的患者更容易在肺部超声中出现B线。

Objective To explore different categories pulmonary edema, especially in failure and pulmonary edema and lung-derived pulmonary edema, through comparing ultrasonic B line number in the lungs, aim to help to assist in pulmonary edema clinical judgment. Methods The participants included 20 cases of heart failure in patients with pulmonary edema, and 25 patients with inflammatory edema, 315 groups of data. The differences of the two kinds of pathological conditions, the patients with different check parts of the lung, B-line number and EVLWI were compared. Result The group of lung-derived pulmonary edema patients of correlation of B line（R^2= 0.7178, P〈0.01）was high the group of failure and pulmonary edema patients（R^2=0.02, P〈0.01）; but there was no statistical differences between the two kinds of pathological conditions, in B-line number and EVLWI. Conclusion Lung-derived patients with pulmonary edema compare with the group of pulmonary edema patients,are easier to appear B-line.
