血液透析对尿毒症患者肺动脉压产生的影响观察

目的研究患者在血液透析之前以及之后的肺动脉压以及相关影响因素的转变情况.方法：收治132 例尿毒症患者,均接受维持性血液透析.在透析前后,对比以下指标：患者的临床资料、实验室指标、超声心动图特点等.结果：透析之前并发肺动脉高压32 例,透析后45 例,透析后PAH 发生率明显高于透析前（P〈0.05）.结论：完成血液透析之后,尿毒症患者并发出现肺动脉高压的危险性明显升高,动静脉内瘘是影响其的重要因素.

Objective: to study the before and after hemodialysis in patients with pulmonary artery pressure and the transformation of the related influencing factors. Methods: 132 patients with uremia renal medicine as the main object of study, are receiving maintenance hemodialysis, and analyzed the the following indexes before dialysis, also to diagnose the following indicators: after dialysis in patients with clinical data and laboratory indexes and echocardiographic characteristics, etc. Results: 32 cases of patients complicated with pulmonary hypertension before dialysis, dialysis after 45 cases of patients complicated with pulmonary hypertension, PAH incidence was significantly higher after dialysis before dialysis, both significant difference, with a statistically significant difference(P<0.05). Conclusion: the completion of hemodialysis, uremia patients complicated with pulmonary hypertension risk increased significantly, arteriovenous fistula is one of the important factors affecting its inside.
