介绍和研究的目的。酸性浓缩物的集中制备和分配系统代表了血液透析的真正创新,与酸袋相比,在便利性和生态可持续性方面。这项研究的目的是比较使用传统的酸袋与酸性浓缩物的集中分配系统,特别关注生态可持续性和便利性方面的差异。方法。在摩德纳大学医院的肾脏科透析和肾脏移植部门安装了Granumix系统®(FreseniusMedicalCare,坏Homburg,德国)。在引入Granumix®系统之前收集的数据(包括用过的酸袋,用于包装的盒子和托盘,使用的酸溶液和木材产生的废物的公斤数,塑料,纸板和残留酸溶液)与实施Granumix®系统后收集的比较。材料消耗等因素,产生的废物量,未使用和浪费的产品,透析会议准备所需的时间和护士的满意度进行了分析,以记录哪种系统更具环境可持续性。结果。2019年在我们的透析中心收集的数据显示,消耗了30,000个酸袋,从木材中产生了超过20,000公斤的废物,塑料和纸板,和大约12,000升的残余酸溶液要处理,操作员的处理重量达到近160,000公斤。使用酸性浓缩物的集中分配系统导致产生的废物大幅减少(2,642千克对13,617千克),待处理的残余酸溶液(2,351升vs12,100升)和操作人员处理的重量(71,522公斤vs158,117公斤)。Conclusions.酸性浓缩物似乎更适合当今透析必须面临的可持续性挑战。特别是由于患者数量的显著增加,这导致了更多的治疗,因此,对生态可持续产品的需求不断增长。
Introduction and aim of the study. The centralized preparation and distribution system of acidic concentrate represents a true innovation in hemodialysis, when compared to acid bags, in terms of convenience and eco-sustainability. The aim of this study is to compare the use of traditional acid bags with the centralized distribution system of acidic concentrate, with particular attention to differences in terms of eco-sustainability and convenience. Methods. At the Nephrology Dialysis and Renal Transplantation Unit of the University Hospital of Modena was installed the Granumix system® (Fresenius Medical Care, Bad Homburg, Germany). Data collected before the introduction of the Granumix® system (including the used acid bags, boxes and pallets used for their packaging, liters of acid solution used and kilograms of waste generated from wood, plastic, cardboard and residual acid solution) were compared with those collected after the implementation of the Granumix® system. Factors such as material consumption, volume of waste generated, unused and wasted products, time required for dialysis session preparation and nurses\' satisfaction were analyzed to document which system was more environmentally sustainable. Results. Data collected in 2019 at our Dialysis Center showed a consumption of 30,000 acid bags, which generated over 20,000 kg of waste from wood, plastic and cardboard, and approximately 12,000 liters of residual acid solution to be disposed of, with a handling weight by operators reaching nearly 160,000 kg. The use of the centralized distribution system of acidic concentrate resulted in a significant reduction in waste generated (2,642 kg vs 13,617 kg), residual acid solution to be disposed of (2,351 liters vs 12,100 liters) and weights handled by operators (71,522 kg vs 158,117 kg). Conclusions. The acidic concentrate appears to be better suited to the sustainability challenge that dialysis must faces today, particularly due to the significant increase in the number of patients, which leads to a higher number of treatments and, therefore, a growing demand for eco-sustainable products.
