摘要： 目的 了解限制水钠摄入对腹膜透析患者血容量和一般状况的影响。方法 随机选择存在轻 度显性水肿的门诊腹膜透析患者14例，用生物电阻抗的方法测定其血容量状态。不增加高渗腹膜透析液的前提下，指导患者限制水盐摄入，监督指导, 跟踪随访4周。观察患者限制水钠摄入后的水肿消退情况，体重和体力活动变化情况。结果 水肿患者生物电阻抗测定实际体重较干体重平均增加(3.54±2.20)Kg。11例患者经水钠限制，体重平均降低(3.27±2.68)Kg，3例患者自行间断加用2.5％的腹膜透析液。63.6％的患者（7/11）水肿消退，27.3％（3/11）的患者水肿减轻，仅有0.9％（1/11）的患者水肿无明显变化。45.5 ％（5/11）的患者感觉活动能力和一般状况改善，其他患者无明显变化。5例（45.5％）患者减少高渗液的用量。讨论 单纯进行有效的水钠摄入的限制可明显改善腹膜透析患者的水肿状态和一般状况。

Abstract: Objective To study the effect of sodium and water restriction on blood volume and systemic fluid status. Methods Fourteen CAPD patients with mild edema were selected, the blood volume of whom were measured by bioimpedence analysis. The patients were advised to take salt and water restriction without using more hypertonic glucose solutions and were followed up for 4 weeks. Results The difference between actual body weight and dry weight of these patients was (3.54±2.20)Kg before salt and water restriction. After taking salt and water restriction, the body weights of 11 patients decreased by (3.27±2.68)Kg. The other 3 patients used more 2.5% glucose dialysate by themselves. Edema disappeared in 7 (63.6%) patients, lessened in 3(27.3%) patients and did not change in only 1 (0.9%) patient. The general life status of 5 patients improved whereas others did not change. Five patients decreased their use of high-osmotic dialysate at the end of the follow-up. Conclusions Salt and water restriction can be effectively used to treat fluid overload in CAPD patients and this can improve the patients' general health status.
