【摘要】 目的 前瞻性观察以新鲜冰冻血浆作透析液行血液透析(HD—PBD)后继续进行高容量 

血液滤过(HVHF),评价其对高胆红素血症患者血清胆红素的清除机制。 方法 选择第四军医大学第一 

附属医院15例肝衰竭患者行HD-PBD治疗6h后,应用同一滤器(AV600)继续行HVHF治疗24h。全部患者 

分别在HD—PBD治疗初始(0h)及开始后2h、4h和6h取滤器动脉端和静脉端血液、流入端和流出端透析 

液,HVHF治疗0h、6h、1 2h和24h取滤器前及滤器后血液,同时留取滤液。观察治疗前后胆红素水 

平的变化。 结果①HD—PBD对胆红素的清除较HVHF明显(P<0.05)。②HD—PBD治疗初始的TB溶质 

清除率(Kd)为(23.0±3.4)ml/min,滤器使用4~6h后弥散作用下降。⑧HD—PBD治疗初始通过弥散 

和吸附的体外清除量分别为(15.6±5.6)mmol/min和(10.3±3.2)mmol/min,滤器使用4~6h后作用下 

降。④HVHF以吸附清除为主,其中治疗初始u及附清除量最大,12h以后吸附清除量而滤过清除量相 

对恒定。⑤HD—PBD治疗初始的体外清除总量高于HVHF[(25.9±8.2)mmol/min vs(7.17±3.34)mmol/ 

rain,P<0.05。 结论HD—PBD联合HVHF治疗对血清胆红素有明显降低作用,其清除机制主要为弥散 

和吸附,对流作用较小。

[Abstract]Objective To prospectively evaluate the effect of hemodialysis with lfesh frozen plasma— 

based dialysate(HD—PBD)plus high volume hemofiltration(HVHF)for the clearance of serum biliubirn in 

patients with heperbiliubinemria.Methods Fifteen patients with liver failure were included in this study.After 

HD—PBD therapy or fthe first 6 hours,patients were then treated with HVHF or 24 hours usifng the same AV600 

iflter.Blood and he tplasma—based dilysatae from vein nd aartery end ofthe ilfter were taken at 0,2,4 nd a6h during 

HD—PBD.Blood before and after filtration as well as the ultrafiltrate were also taken at 0,6,1 2 and 24h during 

HVHF.Biliubirn was determined in dialysate,ultrafiltrate and plasma.Results①The clearance rate of serum 

biliubirn with HD—PBD for 6 hours was signifcantly higher than hatt wih tHVHF orf 24 hours(P<0.05). The 

Kd for serum total biliubirn(TB)was(23.0±3.4)ml/min at the beginning of HD—PBD.After HD—PBD orf 4—6 

hours,the Kd for TB decreased signiifcantly.⑨At the beginning of HD—PBD,the total clearance amount of TB 

by dispersion and adsorption were(15.6±5.6)mmol/min and(10.3±3.2)mmol/min,respectively,and hen t

decreased significantly after using the ilfter or f4~6 hours. In HVHF,TB was mainly removed by adsorption. 

After HVHF or 1f 2h,clearance by adsorption decreased signiicantfly,but he amount tof clearance by ultrafiltra— 

tion remained stable.⑨The clearance amount of TB by HD—PBD at the beginning decreased signiicafntly but 

higher than those by HVHF orf 24 hours(P<0.05).Conclusion HD—PBD plus HVHF,a newly proposed 

modality or fpatients with liver failure,can decrease serum biliubirn eficifently.Dispersion and adsorption are he t

major mechanisms of seum rbiliubirn clearance in HD—PBD,of which the ability decreased gradually after 4 hours 

of dialysis.Convection and adsorption are the major mechanisms of serum biliubirn clearance in HVHF.but the
