血液灌流与血液透析联合治疗尿毒症顽固性皮肤瘙痒临床分析

目的探讨血液灌流(HP)器与血液透析(HD)器串联治疗尿毒症顽固性皮肤瘙瘁的临床结果。方法维持性透析的尿毒症患者100例,随机分为两组,串联组(HP+HD组)50例,采用透析器与灌流器(HA型)串联进行治疗,每月2次,常规透析中其余6次净化方法为HD治疗;对照组(HD组)50例,单纯进行血液透析,外用乳化剂,口服抗组胺药物治疗皮肤症状,每月2次,每次4.h,均采用肝素抗凝,血流量200 mL/min。透析液为碳酸氢盐,流速为500mL/min。串联组先血液灌流及透析2h后再单纯透析2h,共治疗3个月。治疗前后检测Scr,BuN,用放射免疫法测定血液PTH水平,比较2组的肾小球过率(GFR)和透析时间。结果(1)HP+HD组患者治疗后PTH的清除率为(51.1±4.28)%,治疗前后比较差异有统计学意义(P<0.05);皮肤瘙痒缓解率为92.0%。(2)HD组的PTH清除率为(15.9±5.27)%;治疗前后比较差异无统计学意义(P>0.05),皮肤瘙痒缓解率为20.0%。结论血液灌流器与透析器串联治疗尿毒症顽固性皮肤瘙痒能有效消除PTH,缓解皮肤瘙痒症状。血液透析不能有效清除PTH,也不能缓解皮肤瘙。

Clinical analysis on therapeutic alliance of hemoperfusion and hemodialysis in the treatment of stubborn itch of skin due to uremia

Objective To explore the clinical effectiveness of hemoperfusion combined with hemodialysis on the stubborn itch of skin due to uremia.Methods One hundred uremia patients undergoing maintenance hemodialysis were randomly divided into two groups:series group(n=50,given hemodialysis combined with hemoperfusion twice a mouth)and control group(n=50,treated with hemodialysis alone;meanwhile,emulsifying agent external use and antihistamine drug taken orally to alleviate the itch).De- coagulant:heparin;the blood f...
