摘　　要：目的探讨应用双腔负压吸引法清除维持性血液透析患者长期留置导管内血栓的作用。方法将12例维持性血液透析的长期留置导管患者随机分为对照组(6例,235例次)和观察组(6例,232例次)。对照组采用常规操作方法,即单腔负压吸引法上机,利用血泵对透析导管的动脉腔进负压吸引;观察组采用双腔负压吸引法上机,即在常规操作流程中,于上机前增加利用透析机血泵对透析导管的静脉端进行负压吸引这一步骤,实现对透析导管的动、静脉双腔均进行负压吸引。结果观察组血栓清除率为3.02%,比对照组(1.70%)高1.78倍;两组透析器凝血情况比较,差异无统计学意义(P>0.05)。结论双腔负压吸引法对透析导管内不牢固血栓的清除效果优于单腔负压吸引法,同时并不增加透析器的凝血。Objective To explore the effect of removing blood clots in permanent hemodialysis catheters through double lumen pres- sure suction technique. Methods Totally, 12 patients on maintenance hemodialysis therapy were randomly divided into a control group （6 cases, 235 times of hemodialysis） and an observation group （6 cases, 232 times of hemodialysis）. The control group were subjected to conventional methods. Namely, single cavity pressure suction method（suctioning the arterial lumen of the dialysis ca- theter with a pump）. The observation group were subjected to double lumen pressure suction technique. Namely, in routine process, the venous lumen, besides the arterial lumen, of the dialysis catheter was suction. Results Thrombus clearance rate in the observation group was 3. 02%, 1.78 times higher than the control group （1.70%）. The rates of dialyser coagulation between the 2 groups had no significant difference （P〉0.05）. Conclusion Double lumen pressure suction method is able to remove unstable blood clots in dialysis catheter. Being superior to single lumen suction, this method does not increase blood coagulation in dialyser.
