| 摘 要： | 目的通过联机尿素监测器(OCM)实时动态监测KT/V,并对影响KT/V的相关因素进行分析。方法采用德国Fresenius4008S透析机及随机附带OCM组件,实时动态监测31例维持性血液透析患者,共308人次KT/V,同时记录透析器类型、透析时间、单超时间、血液流量,透析开始时尿素清除率(K1),透析两小时尿素清除率(K2),透析结束时尿素清除率(K3)。结果KT/V值与透析时间和血液流量成正相关,与尿素分布容积成负相关;尿素清除率和透析时间呈直线负相关,透析液流量由500ml/min调节到800ml/min,透析器的尿素清除率约提高15%。结论提高KT/V的有效方法是增加血流量、延长透析时间、提高透析液流量和使用高效率透析器;复用透析器不宜超过4次。

| Abstract: | Objective To inspect KT/V by online clearance monitoring and analysed the results. Methods 31 patients with maintenance hemodialysis were investigated by the Fresenius 4008S with OCM appliance. Results The positive correla- tion among KT/V, hemodialysis time, blood volume per minute and the negative correlation between KT/V and the urea distri- bution volume. Conclusion The effective ways to enhance KT/V are to increase the blood volume per minute, prolong hemodialysis time and add dialytic liquid per minute. Dialyzer reuse is suitable for 4 cycles. |
