Abstract

Introduction: Intra-dialytic hypotension (IDH) remains the commonest problem associated with routine haemodialysis treatments. Fluid shifts from intracellular(ICW) and extracellular(ECW) compartments to refill plasma volume during haemodialysis with ultrafiltration.

Methods: We studied the effect of relative changes in ICW and ECW indifferent body segments using multifrequency segmental bioimpedance during haemodialysis and IDH episodes.

Results: Of 42 haemodialysis patients,16 patients (38.1%) developed IDH within the first hour of dialysis. Patients with and without early IDH were well-matched for demographics and starting bioimpedance measurements. However, after 60 min, the relative change in in ECW/ICW ratio between the non-fistula arm and leg was significantly different for the early IDH group median -1.07 (-3.33 to 0.8) versus 0.61 (-0.78 to 1.8), p < 0.05, whereas there no differences in ultrafiltration rate, relative blood volume monitoring or on-line clearance.

Conclusion: Monitoring serial changes in fluid status in different body compartments with bioimpedance may potentially prevent IDH in the future.

在血液透析过程中，血液透析室内生物阻抗测量值的变化对早期透析室内低血压的影响。

导言：透析内低血压（IDH）仍然是常规血液透析治疗中最常见的问题。在超滤血液透析过程中，液体会从细胞内（ICW）和细胞外（ECW）分区转移，以补充血浆容量：我们利用多频节段生物阻抗研究了血液透析和IDH治疗期间ICW和ECW相对变化对身体各节段的影响：在42名血液透析患者中，有16名患者（38.1%）在透析的第一个小时内出现了IDH。有早期 IDH 和没有早期 IDH 的患者在人口统计学和起始生物阻抗测量方面非常匹配。然而，60 分钟后，非瘘管手臂和腿部的 ECW/ICW 比率的相对变化在早期 IDH 组的中位数-1.07（-3.33 至 0.8）与 0.61（-0.78 至 1.8）之间存在显著差异，P 结论：利用生物阻抗监测身体各部分液体状态的连续变化有可能在未来预防 IDH。
