血液透析可以将患者体内因肾功能衰竭而滞留在体内的各种代谢性废物清除,并且可以减轻机体各个器官、组织细胞,因代谢废物产生的毒性作用,还可以将原发病产生的感染性炎症介质排出体外,如肿瘤坏死因子、白细胞介素2等,有效的控制炎症反应,从而避免患者出现全身炎症反应综合征、多器官功能障碍综合征等情况,还可以通过调节透析液电解质的浓度,迅速纠正电解质平衡失调,通过超滤水排除体内多余的水分,减轻循环负荷,从而达到纠正机体内环境紊乱的目的[1-2]。
Hemodialysis can remove all kinds of metabolic wastes in the body due to renal failure, and can reduce the toxic effects of various organ and tissue cells in the body due to metabolic waste, and can also reduce the infectiousness caused by the original disease Inflammatory mediators excreted in vitro, such as tumor necrosis factor, interleukin 2, effectively control the inflammatory response, so as to avoid patients with systemic inflammatory response syndrome, multiple organ dysfunction syndrome, etc., but also by adjusting the dialysate electrolyte concentration , Quickly correct electrolyte imbalance, remove excess body water by ultrafiltration, reduce the cycle load, so as to achieve the purpose of correcting the body environment disorders [1-2].
