Abstract：Objective To explore the dynamic changes in B-line counts at the posterolateral alveolar and/or pleural syndrome point(PLAPS point)during the early stage of acute cerebral hemorrhage,to assess their diagnostic value in the early identification of neurogenic pulmonary edema(NPE).Methods This retrospective study analyzed 40 patients with acute cerebral hemorrhage who were admitted to Chongqing Seventh People's Hospital from January to October 2024,and they were categorized into the NPE group and the non-pulmonary edema group based on the presence or absence of NPE.All patients underwent bedside lung ultrasound scans at the PLAPS point,and B-line counts were recorded.Results The B-line count was significantly higher in the NPE group than in the non-pulmonary edema group(5.13±1.22 vs 2.32±1.41,P<0.01).ROC curve analysis showed that B-line counts at the PLAPS point had a sensitivity of 92.50%and a specificity of 86.42%for diagnosing NPE,with an optimal cutoff value of 3.5 lines.Additionally,in some patients with NPE,B-line counts at the left PLAPS point were generally higher than those at the right side.Conclusion B-line quantification at the PLAPS point offers high sensitivity and specificity for the diagnosis of NPE,making it particularly valuable for early detection in patients with acute cerebral hemorrhage.Left-sided B-line predominance may indicate greater fluid accumulation in the left lung,which could inform and refine ultrasound assessment strategies.Wider clinical adoption is recommended.
