BACKGROUND Patients with chronic kidney disease are at higher risk of developing cardiovascular disease. Chronic exposure to intermittent hemodialysis may be a source of added stress to the cardiovascular system; intradialytic hypotension is a common complication of hemodialysis, and repeated events may lead to hemodynamic stress and ischemic injuries. Administration of non-pneumatic compression stockings to the lower limbs has demonstrated hemodynamic stabilizing effects in other settings and may provide similar benefits in the kidney disease population. Therefore, we conducted this pilot study assessing the feasibility and tolerability of the application of non-pneumatic compression stockings to patients with kidney disease. We also assessed the changes in hemodynamic measurements following the application of the compression stockings to explore the biological feasibility of this being an effective intervention for intradialytic hypotension. METHODS Fifteen individuals were enrolled in the study (5 healthy, 5 chronic kidney disease patients, and 5 dialysis patients). Outcomes including hemodynamic parameters such as cardiac output, peripheral vascular resistance, and blood pressure were measured using continuous pulse wave analysis. Changes in global longitudinal strain were measured via echocardiography. These outcome measurements were made before and after the application of compression stockings. RESULTS All study participants tolerated the compression garments well and without complication. Hemodynamic response to lower body compression caused varying effects on cardiac output, mean arterial pressure and global longitudinal strain. Some individuals saw large improvements in hemodynamic parameters while in others the opposite effect was observed. No consistent response was elicited. CONCLUSIONS Application of compression stockings to patients with renal dysfunction is well-tolerated. However, significant variations in hemodynamic outcomes exist, and may be a barrier for larger scale trials without prior identification of specific patient characteristics indicating likely benefit from the application of external compression.

肾功能不全患者对非气动抗冲击压服的血流动力学反应。

背景技术患有慢性肾脏疾病的患者患心血管疾病的风险更高。长期暴露于间歇性血液透析可能会增加心血管系统的压力。透析内低血压是血液透析的常见并发症,反复发生的事件可能导致血液动力学压力和缺血性损伤。对下肢使用非气动加压袜已证明在其他情况下具有血流动力学稳定作用,并且可能在肾脏疾病人群中提供类似的益处。因此,我们进行了这项初步研究,以评估将非气动加压袜应用于肾脏疾病患者的可行性和耐受性。我们还评估了加压袜的应用后血液动力学测量的变化,以探讨将其作为透析内低血压有效干预措施的生物学可行性。方法该研究共纳入15名患者(5名健康者,5名慢性肾脏病患者和5名透析患者)。使用连续脉搏波分析测量包括血流动力学参数(例如心输出量,外周血管阻力和血压)的结果。通过超声心动图测量整体纵向应变的变化。这些结果的测量是在施加压力袜之前和之后进行的。结果所有研究参与者对加压衣的耐受性良好且无并发症。对下半身压缩的血流动力学响应对心输出量,平均动脉压和整体纵向应变产生不同的影响。有些人的血液动力学参数有很大的改善,而另一些人则观察到相反的效果。没有引起一致的反应。结论加压袜在肾功能不全患者中的耐受性良好。但是,血液动力学结果存在显着变化,如果没有事先确定患者的特定特征(可能从外部加压应用中获益),可能会成为大规模试验的障碍。试验注册ClinicalTrials.gov,标识符:NCT02915627,注册日期:2016年9月27日。有些人的血液动力学参数有很大的改善,而另一些人则观察到相反的效果。没有引起一致的反应。结论加压袜在肾功能不全患者中的耐受性良好。但是,血液动力学结果存在显着变化,如果没有事先确定患者的特定特征(可能从外部加压应用中获益),可能会成为大规模试验的障碍。试验注册ClinicalTrials.gov,标识符:NCT02915627,注册日期:2016年9月27日。有些人的血液动力学参数有很大的改善,而另一些人则观察到相反的效果。没有引起一致的反应。结论加压袜在肾功能不全患者中的耐受性良好。但是,血液动力学结果存在显着变化,如果没有事先确定患者的特定特征(可能从外部加压应用中获益),可能会成为大规模试验的障碍。试用注册ClinicalTrials.gov,标识号:NCT02915627,注册日期:2016年9月27日。血液动力学结果存在显着变化,并且可能在没有事先确定患者特定特征(可能从外部加压应用中获益)的情况下进行大规模试验。试验注册ClinicalTrials.gov,标识符:NCT02915627,注册日期:2016年9月27日。血液动力学结果存在显着变化,并且可能在没有事先确定患者特定特征(可能从外部加压应用中获益)的情况下进行大规模试验。试用注册ClinicalTrials.gov,标识号:NCT02915627,注册日期:2016年9月27日。
