| 摘 要： | 目的探索应用改良的节段生物电阻抗法-小腿电阻抗比值(CBIR)评估血液透析(HD)患者的容量状况。方法使用多频生物电阻抗分析仪测定157例健康志愿者右侧小腿的电阻抗值,计算CBIR(impedance 200k/impedance 5k)作为容量负荷指标,并确定正常参考值范围。同时检测117例HD患者透析后CBIR,观察患者容量负荷状况。结果健康志愿者的CBIR为(0.774±0.028),由此确定正常参考值范围为0.746～0.802(均数±1个标准差)。HD组透析后CBIR明显高于正常对照组(0.790±0.033)vs(0.774±0.028),P0.001],其中容量增高者(CBIR0.802)、容量正常者(CBIR在0.746～0.802)和容量降低者(CBIR0.746)分别占36.8%,53.0%,10.2%。在使用降压药的剂量无显著差异的情况下,CBIR增高组高血压的发生率明显高于CBIR正常组(P=0.008)和CBIR降低组(P=0.003)。结论小腿电阻抗检测可能是评估HD患者容量状况的有效方法。

| Abstract: | Objective To evaluate volume status in hemodialysis(HD) patients by modified bioimpedance spectroscopy-calf bioimpedance ratio(CBIR).Methods Calf bioimpedance was measured by bioimpedance spectroscopy.As an index of volume status,CBIR was calculated as follows:CBIR = impedance of 200 kHz/impedance of 5kHz.Reference CBIR range was obtained from 157 healthy volunteers.The volume status of 117 HD patients post-dialysis was assessed using the CBIR from healthy volunteers as the reference CBIR range.Results CBIR... |
