腹膜透析患者腹膜平衡试验及其操作

Peritoneal equilibration Test and Its Operation on CAPD Patients

对52例腹膜透析患者进行腹膜平衡试验（PET），判断腹膜对小分子物质的转运能力。其中，高转运者6例（11．5％），高于平均转运者35例（67．4％），低于平均转运者9例（17．3％），低转运者2例（3．8％）。分析腹膜转运功能与透析充分性的关系，在标准剂量透析状态时高转运和低转运类型的患者平均尿素KT／V及Ccr明显低于其它转运类型，在低于平均转运的患者中有残余肾功能者KT／V及Ccr明显高于无尿或少尿者。根据PET的结果，对11例患者调整了透析方案，透析效能明显改善，说明PET有助于腹透选择或调整适合CAPD患者的透析方式。同时对PET的操作过程中应注意的一些问题进行了总结和讨论。

In order to observe the transport ability of peritoneum to small molecular substances, peritoneal equilibration test (PET) was performed in 52 CAPD patients. By analysing the relationship be-tween peritoneal transport function and dialysis adequacy,we found the average urea KT/V and Cr weresignificantly lower in high and 1ow transport groups (n = 6 and n= 2) than in high average and low aver-gae groups (n=35 and n= 9). According to the results of PET,we adjusted the dialysis program of 11patients and the dialysis adequacy was markedly improved. We conclued that PET was helpful for select-ing and adjusing CAPD program,and discussed some questions which should be payed more attention inPET operation.
