化学成分和新的生产技术的最新进展导致透析膜的生物相容性和透过性得到改善。其中,一种名为中等截断(MCO)的新型膜的创建代表着朝着改善临床结果迈出的重要一步。这种膜的开发是为了改善中到高分子量(MW)溶质(即5-50 kDa范围内的尿毒症毒素)的清除。MCO膜具有独特的截留和截留特性。由于改进了筛分轮廓,MCO膜也被描述为高截留率。在MCO血液透析器中实现的显著内部过滤提供了对中到高MW溶质的显著对流清除。与高截留膜相比,在MCO膜中观察到的白蛋白的边际损失被认为是可以接受的,即使不是有益的,也可以产生一定的蛋白质结合溶质的清除。MCO膜在经典透析方式中的应用体现了一种称为扩张式血液透析的新技术。这种疗法不需要特定的软件或专用硬件,使其能够在透析液质量符合当前标准的所有环境中应用。
Recent advances in chemical composition and new production techniques resulted in improved biocompatibility and permeability of dialysis membranes. Among these, the creation of a new class of membranes called medium cut-off (MCO) represents an important step towards improvement of clinical outcomes. Such membranes have been developed to improve the clearance of medium to high molecular weight (MW) solutes (i.e. uraemic toxins in the range of 5–50 kDa). MCO membranes have peculiar retention onset and cut-off characteristics. Due to a modified sieving profile, MCO membranes have also been described as high-retention onset. The significant internal filtration achieved in MCO haemodialysers provides a remarkable convective clearance of medium to high MW solutes. The marginal loss of albumin observed in MCO membranes compared with high cut-off membranes is considered acceptable, if not beneficial, producing a certain clearance of protein-bound solutes. The application of MCO membranes in a classic dialysis modality characterizes a new technique called expanded haemodialysis. This therapy does not need specific software or dedicated hardware, making its application possible in every setting where the quality of dialysis fluid meets current standards.
