血浆置换是应用血浆单采术清除患者体内的异常物质,同时以等量置换液回输给患者。我们用以治疗2例多发性骨髓瘤,取得了较好效果。例1:男,49岁。患多发性骨髓瘤(IgG型),曾用M_2方案治疗6个疗程。行血浆置换木前ESR142mm/h,IgG 64.01g/L,蛋白电泳r0.55。置换血浆1495ml后,ESR降为11mm/h,IgG52g/L。替代液用新鲜同型血浆、6%羟乙基淀粉及生理盐 Plasma exchange is the use of plasma apheresis removal of abnormal substances in patients with the same amount of replacement fluid back to the patient. We used to treat 2 cases of multiple myeloma, and achieved good results. Example 1: Male, 49 years old. Suffering from multiple myeloma (IgG type), had used M 2 regimen for 6 courses. Plasma exchange pre-ESR142mm / h, IgG 64.01g / L, protein electrophoresis r0.55. After replacing 1495 ml of plasma, ESR was reduced to 11 mm / h and IgG 52 g / L. Replacement fluid with fresh plasma, 6% hydroxyethyl starch and physiological salts
